What is mass percent?

Mass percent is defined as a way of expressing a concentration or describing the component in a particular mixture.

It can also be defined as a mass of a element or solute divided by the mass of compound or solvent.  

Mass percent of sulfur of sample A

= 32 + 48 = 80

= 32 / 80 x 100

= 40 %

Mass percent of sulfur of sample B

= 30 + 30 = 60

Describe the properties of noble gases. based on their electronic arrangement, explain whether they can exist alone in nature.

Answers

Noble gases exist as monatomic gases, which means that their molecules consist of a single atom.

What are noble gases?

A "Noble gas" can be defined as a gas which does not undergo chemical reactions. Examples of Noble gases are helium, Neon, Argon, Krypton, Xenon, and Radon.

Properties of noble gases:

Noble gases are the least reactive of all elements because they have eight valence electrons, which fill their outer energy level. That's why noble gases rarely react with other elements and form compounds.

Atoms of noble gases do not bond with other gases. Only helium exists as atoms of Helium, not as diatomic molecules. Helium does not form compounds with atoms of other elements.

A. Carbon monoxide blocking oxygen in the blood.
B. Heavy metals leaking into groundwater and damaging the nervous system.
C. Carbon particles causing breathing problems.
D. Carbon particles making buildings dirty.

Answers

Carbon monoxide blocks oxygen in the blood. Hence, option A is correct.

What is combustion?

Combustion is a chemical process or a reaction between Fuel (Hydrocarbon) and Oxygen.

During incomplete combustion part of the carbon is not completely oxidized producing carbon monoxide (CO). Incomplete combustion uses fuel inefficiently and carbon monoxide is released.

Carbon monoxide gas diffuses rapidly across the pulmonary capillary membrane, binding to haemoglobin with an affinity 200 times that of oxygen to form carboxyhemoglobin. By displacing oxygen, CO decreases the oxygen-carrying capacity and oxygen delivery to tissues, causing marked cellular hypoxia and acidosis.

Hence, option A is correct.

All liquids evaporate if exposed to certain elements.

What is Evaporation ?

Evaporation is the process by which water changes from a liquid to a gas or vapor.

Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.

All liquids evaporate if exposed to certain elements.

The rate at which a liquid evaporates depends on its molecular structure.

The other factors that affect evaporation are surface area, temperature and air movement.

We can also do a few fairly simple experiments to demonstrate the effect that the various factors have on the rate of evaporation.

If 1.32 g MgO is combined with 100.0 mL of 1.00 M HCl in a coffee cup calorimeter, the temperature of the HCl solution increases from 24.2 °C to 34.4 °C. Calculate the enthalpy change for the reaction per mole of MgO. Assume that the specific heat of the HCl solution is 4.18 J/g·°C and its density is 1.00 g/mL.

MgO(s) + 2HCl (aq) MgCl2 (aq) + H2O (l)

Answers

The change in enthalpy for the reaction per mole is -130KJ/mol.

Given,

Reaction: MgO(s) + 2HCl (aq) →MgCl₂ (aq) + H₂O (l)

1.32 g MgO is combined with 100.0 mL of 1.00 M HCl in the cup of coffee.

Change in temperature, ΔT=34.4 °C-24.2 °C =10.2°C

Specific heat of the HCl solution, c= 4.18 J/g·°C

Density= 1.00 g/mL

Mass can be written as the product of density and volume.

Mass= Density × Volume= 1g/ml × 100 ml=100g

Heat can be written as

Heat, Q=mcΔT=100g×4.18 J/g·°C×10.2°C=4263.6J

Number of moles of the MgO,

n= (mass of MgO)/(Molar mass)= 1.32g/(40.3g/mol)= 0.03275 mol

Change in Enthalpy, ΔH=-Q/(n)=(-4263.6J)/(0.03275 mol)

ΔH= -1300186J/mol= -130KJ/mol

Hence, the change in enthalpy for the reaction per mole is -130KJ/mol.

What is a chemical equation?

A chemical equation is a symbolic representation of a chemical reaction; Reactants are represented on the left and the products on the right.

The law of conservation of mass states that in a closed system, mass is neither created nor destroyed during a chemical or physical reaction. The law of conservation of mass is applied whenever you balance a chemical equation. It is also applicable to stoichiometry. A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.

Consider the balanced equation for the combustion of methane.

[tex]CH_4 + 20_2 \implies CO_2 + 2H_2O[/tex]

All balanced chemical equations must have the same number of each type of atom on both sides of the arrow.

In this equation, we have 1 C atom, 4 H atoms, and 4 O atoms on each side of the arrow.

The number of atoms does not change, so the total mass of all the atoms is the same before and after the reaction. Mass is conserved.

The same atoms of the same element that are present in the reactants are also present in the products, according to the rule of conservation of matter.

This leads us to believe that the response to the question is true because: It has the same atom kinds on both sides of the reaction arrow (Option C)

It requires 2,500 joules to raise a certain amount of water (c = 4.186 j/g°c) from 20.0°c to 60.0°c. what is the mass of the water that is being heated? 15 g 40 g 63 g 80 g

Answers

Answer:

15 grams of water will absorb 2,500 Joules  in going from 20.0 to 60.0 C.

Explanation:

The heat involved in raising a mass (m) of a substance with a specific heat (c) from one temperature to another (Delta T) is given by:

Heat = mc(Delta T)

2,500 Joules = m*(4.186J/gC)*(60C-20C)

2,500 Joules = m*(4.186J/gC)*(40C)

2,500 Joules = m*(4.186J/gC)*(40C)

m = (2,500J)/(4.186*40J/g)

m = 14.93 grams

a serving of a particular fruit dessert contains 20.0 g of sugar. if all the sugar is sucrose, c12h22o11, how many molecules of sugar are present in this serving?

Answers

Taking into account the definition of Avogadro's number and molar mass, 3.49334×10²² molecules of sucrose are present.

Definition of molar mass

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

Avogadro's Number

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Molecules of sugar in this case

In first place, the molar mass of sucrose is 342 g/mole. So, you can apply the following rule of three: If by definition of molar mass 342 grams of the compound are contained in 1 mole, 20 grams of the compound are contained in how many moles?

[tex]amount of moles=\frac{20 gramsx1 mole}{342 grams}[/tex]

amount of moles= 0.058 moles

Now, considering the Avogadro's number, you can apply the following rule of three: If 1 mole of the compound contains 6.023×10²³ molecules, 0.058 moles contains how many molecules?

amount of moleculas= (6.023×10²³ molecules × 0.058 moles)÷ 1 mole

amount of molecules= 3.49334×10²² molecules

Finally, 3.49334×10²² molecules of sucrose are present.

What causes ionic bonding between two atoms?

Answers

Answer:

Ionic bonding happens when an atom of an element gives one or more of its electrons to the other element's atom..it usually takes place between metal and non metal atoms...like in NaCl, Na gives its valence electron to chlorine and completes its own octet. Chlorine accepts the electron and completes its own octet too...but now both the atoms have an opposing charge and hence they attract each other to form an IONIC bond.

Ionic bonds are the strongest of the bonds...here complete transfer of electrons takes place unlike covalent bonds.

Moodle is looking for a number only, no units.)

Answers

The molarity of the unknown solution will be 1.310 M.It is denoted by M₂.

What is molarity?

Molarity is defined as the ratio of the moles to the volume of the solution.

Given data;

Volume of unknown solution,V₁ = 10.5 mL

The volume of diluted solution,V₂ = 80.0 mL

Molarity of new solution,M₁ = 0.172 M

Molarity of unknown solution, M₂=?

For dilution we use the formula as;

M₁V₁=M₂V₂

M₂=M₂V₂/V₁

M₂ = ( 80 × 0.172 ) / 10.5

M₂= 1.310 M

Hence the molarity of the unknown solution will be 1.310 M.

For  Isotope B ;

% Abundance =  30/50 x 100

The following three significant activities are involved in photosynthesis:

1. Chlorophyll absorbs light energy.

2. Water molecules are divided into hydrogen and oxygen and light energy is converted to chemical energy.

3. Carbon dioxide is converted to sugars.
