Which of these reactions are acid-base reactions?

Answers

Answer:

The fifth answer choice (NH3 + H2O = NH4+ + OH-)

Explanation:

An acid-base reaction occurs when an acid and base combine, and the acid, (which is H2O in this case) "donates" a proton, or an H+ to the base. In this reaction, H2O gave one of its H+ to NH3, to make NH4+ and OH-. NH4+ now has a positive charge because it gained a positive ion, while OH- now has a negative charge because it gained a negative ion.

A 10g of limestone is treated with dilute hydrochloric acid.The liberated gas measured at 27°C and 750mmHg is 18.5dm^3.Find the percentage purity of calcium carbonate.​

Answers

Your question's data is not correct, it should be 100 grams of limestone instead of 10 grams, You will find the correct solution below according to that.

The percentage purity of calcium carbonate is 82.5%

The balanced chemical equation is

CaCO₃ + 2HCl  →  CaCl₂ + H₂O + CO₂

Because CO₂ is a gas, you can easily convert it to mole directly

No. of mol of CO₂ = volume dm³ /22.4 dm³

No. of mol of CO₂ = 8.5 dm³ / 22.4 dm³

No. of mol of CO₂ = 0.825 mol

According to equation 1 mole of CO2 is made from 1 mole of CaCO3

So, 0.825 mole of CO2 will be made from 0.825 mole of CaCO3

Mass of CaCO3 = moles of CaCO3 × Molar mass of CaCO3

Mass of CaCO3 = 0.825 × 100 grams

Mass of CaCO3 = 82.5 grams

Percentage purity of CaCO3 = (mass of CaCO3/Total mass of CaCO3) × 100

Percentage purity of CaCO3 = (82.5/100) × 100 %

Percentage purity of CaCO3 = 82.5 %

Thus we can say that as percentage purity is the percentage of mass of pure compound on per unit of total compound, the percentage purity of the calcium carbonate will be 82.5 %

Sulfur dioxide (SO2)

Why is this the best option?

To determine the polarity of the molecule, there are two requirements. The first one has a variety of terminal atoms, whereas the second has a lone pair on the center atoms. The molecule is polar if one of the requirements is met; else, it is nonpolar. The oxygen atom is a terminal atom because it surrounds the sulfur atom, which is the center element in the SO2 molecule's Lewis structure. In this molecule, there are two terminal oxygen atoms. If we look at the first criterion, we can see that it is not met because it calls for the presence of two separate terminal atoms.

Answers

Activation energy is required so reactants can move together, overcome forces of repulsion, and start breaking bonds.

What is activation energy?

The minimum amount of energy that is needed to activate atoms or molecules to a condition in which they can undergo a chemical transformation or physical transport.

The activation energy of this chemical reaction is high that it will not start at room temperature. This is why a source of heat is required to start the fire: the “energy barrier” must be overcome before the reaction can proceed further.

In any chemical reaction, existing chemical bonds should be broken before new bonds formation. The breaking of chemical bonds requires an input of energy. In some reactions, the thermal energy at room temperature is enough to break the bonds.

In other cases, the thermal energy at room temperature does NOT give enough energy to break the needed bonds (by facilitating sufficiently energetic molecular collisions) to get the reaction started.

Magnesium burns in air with a dazzling brilliance to produce magnesium oxide: 2 Mg(s) + O2(g) → 2 MgO(s) How many moles of O2 are consumed when 2.10 mol of magnesium burns?

Answers

Answer:

1.05 mols of O2 gas

Explanation:

For this type of problem, it's important to understand what the balanced Chemical equation tells us:

Balanced Chemical equations

Let's look at the balanced chemical equation:

[tex]2Mg(s)+O_2(g)-- > 2MgO(s)[/tex]

This equation two sides of the reaction arrow.  On the left are the reactants (things you start with, and that react during the chemical reaction), and on the right side are products (things that are produced during the chemical reaction that you end with).

The numbers in front of each compound tell how many of molecules are involved for a full reaction without anything left over.  A "mol" is a large quantity ([tex]6.022*10^{23}[/tex]), in this case, of molecules , since it's unlikely you're only taking a single molecule of each substance (it would be so tiny, you wouldn't even know you were doing the reaction).

So,for every 2 moles of Magnesium used, we'll also need 1 mole of Oxygen, and it will produce 2 moles of Magnesium Oxide.

In a way, during the reaction it's almost like 2 moles of Magnesium is equal to 1 mole of Oxygen and is equal to 2 moles of Magnesium Oxide:

[tex]2 mol Mg(s)=1mol O_2(g)=2molMgO(s)[/tex]

From here, we can build some unit ratios, to convert between the known quantity of moles we have, and find the unknown quantity of moles that are requested.

Finding the right unit ratio

We know that we are looking at 2.10 mol of Magnesium, so we want a unit ratio with moles of Mg on the bottom.  We want to find moles of O2, so we want a unit ratio of moles of O2 on top.

The unit ratio we want is the middle part of the equation, divided by the left part of the equation.

[tex]2 mol Mg(s)=1mol O_2(g)\\\frac{2 mol Mg(s)}{2 mol Mg(s)}=\frac{1mol O_2(g)}{2 mol Mg(s)}\\1=\frac{1mol O_2(g)}{2 mol Mg(s)}[/tex]

Since this quantity is 1, it is a unit ratio and can be multiplied to other things to change their units (for this problem).

Finding the answer

Starting with what we know, and multiplying by our unit ratio:

[tex]2.10 mol Mg(s)*\frac{1mol O_2(g)}{2 mol Mg(s)}=1.05mol O_2(g)[/tex]

Notice that the units from the first quantity cancel with the units on the bottom of the fraction, leaving only the unit on top of the fraction ... the exact units we wanted!

So, 1.05mols of O2 would be consumed during the reaction if exactly 2.10moles of Magnesium are burned.

How many moles of O2 are consumed when 2.10 mol of magnesium burns?

Answers

1.05 moles of oxygen gas are consumed in the reaction when 2.10 mol of magnesium burns.

What are moles?

A mole is defined as [tex]6.02214076 × 10^{23}[/tex] of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

We are given:

Moles of magnesium = 2.10 mol

For the given chemical reaction:

2Mg + O₂ → 2MgO.

By Stoichiometry of the reaction:

2 moles of magnesium react with 1 mole of oxygen gas.

So, 2.10 moles of magnesium will react with = [tex]\frac{1}{2}[/tex] X2.10 =1.05 moles

Hence, 1.05 moles of oxygen gas are consumed in the reaction.

How many possible electrons can be held in the Bohr model n=8 energy level?

Answers

Electrons in the Bohr model follow the number of elements in the rows of the periodic table.

2 in the first orbit

8 in the second and third ring

18 in the fourth etc...

The Bohr model is a simplistic means of explaining the placement of the subatomic particles of the elements of the periodic table.

The Bohr model arrangement of electrons follows the same pattern as the periodic table.

2 elements in the first row, and 2 electrons in the first orbit.

8 elements in the second row, and 8 electrons in the second orbit.

8 elements in the third row, and 8 electrons in the third orbit.

The fourth and fifth orbits would therefore hold 18 electrons.

For most chemists, the Bohr model does not work well beyond the third row of the periodic table because the model becomes quite oversized and bulky.

Answers

0.342 x [tex]10^(^1^6^)[/tex])  photons are required to emit 1 joule of energy.

What is a photon?

A photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic (or light) energy.

We need to find the number of photons emitted per second.

So we have E = hc ÷ λ

= (6.6 x [tex]10^-(^3^4^)[/tex]x 3 x [tex]10^8[/tex] m/s) ÷ 6.78 x [tex]10^(^-^7^)[/tex]nm

= 2.92 x [tex]10^(^-^1^9^)[/tex]Joules

Now number of photons per second = I / E (I = intensity)

= 1 x [tex]10^(^-^3^)[/tex] joule / sec ÷ 2.92 x [tex]10^(^-^1^9^)[/tex]joule

= 0.342 x[tex]10^(^1^6^)[/tex]

Hence, 0.342 x [tex]10^(^1^6^)[/tex])  photons are required to emit 1 joule of energy.

Surpassed only by silver, copper is a highly conductive metal. This means electricity can pass through it with greater ease, making it ideal for use in electrical wires. Companies can use other conductive metals to create electrical wires.

15. Corrosion

Copper metal when exposed to air turns green in color due to corrosion. When the copper vessel is exposed to air in the rainy season, the metal reacts with gases, moisture, and atmospheric gases to form a mixture of copper carbonate and copper hydroxide. This gives a green color to the surface of the copper meta

16. Silicon

silicon is the backbone of the electronics industry. Because silicon is the reason for the fast development happened in the field of electronics. therefore, silicon is the backbone of electronics.

17. High chemical reactivity

Sodium is stored under kerosene because of its high chemical reactivity with almost all of the other elements (for example oxygen from the air which oxidizes it instantly). Kerosene and mineral oil are the only chemicals that make sodium inert. Usually, when Na reacts with a solvent it liberates hydrogen gas from its composition.

18. Metal oxides are oxides of metals. Nonmetal oxides are oxides of nonmetals. The main difference between metal oxides and nonmetal oxides is that metal oxides are basic compounds whereas nonmetal oxides are acidic compounds.

19.  Silver is more likely to tarnish near a petroleum refinery than in a place far away from it because when silver reacts with petroleum or hydrogen sulfide present in it as a pollutant in the air, it starts forming a black coating of silver sulfide.

20. A noble metal is ordinarily regarded as a metallic chemical element that is generally resistant to corrosion and is usually found in nature in its raw form. Gold, platinum, and the other platinum group metals (ruthenium, rhodium, palladium, osmium, iridium) are most often so classified. Silver, copper, and mercury are less often to sometimes included as noble metals although each of these usually occurs in nature combined with sulfur.
