It is possible for citric acid and baking soda to create water because they are both chemical compounds that can react with each other to create new compounds.

When citric acid and baking soda are mixed together, they undergo a chemical reaction known as a neutralization reaction. This type of reaction occurs when an acid and a base react to form salt and water.

In this case, citric acid is an acid and baking soda is a base. When they are mixed together, the acid and base neutralize each other, creating a salt compound and water. The acid and base cancel out each other's properties and neutralize the solution. The acid donates a proton (H+) to the base, and the base accepts it to form water.

The gas that was measured by the students, is the carbon dioxide (CO2) that is produced as a byproduct of this reaction. As the acid and base react, they release carbon dioxide gas, which is 4.2 grams more than they had at the start. The reaction can be written as follows:

[tex]C_{6}[/tex][tex]H_{8}[/tex][tex]O_{7}[/tex] [tex]_{(aq)}[/tex] + [tex]NaHCO_{3}[/tex] [tex]_{(s)}[/tex] → [tex]NaC_{6}[/tex][tex]H_{5}[/tex][tex]O_{7}[/tex] [tex]_{(aq)}[/tex] + [tex]H_{2} O[/tex] [tex]_{(l)}[/tex] + [tex]CO_{2}[/tex] [tex]_{(g)}[/tex]

Activation energy  can be defined as the minimum energy required by particles at the reactant side for a chemical reaction to occur. According to the reaction conditions, specifically for reversible reactions, reactants can in turn become products and vice versa.

Exothermic reaction can be defined as the process where the heat energy is liberated in the conversion of the reactants to products for the forward reaction. We know that the heat is created in this process a small part of the energy may be initially provided to activate the reactant particles but once the reaction is in ongoing state it produces good amount of heat energy to keep the process in flow.

The reverse reaction, we know that is the endothermic in nature. The heat energy is absorbed in the conversion of the products ( now reactants in the reverse reaction ) to reactants ( now products in the reverse reaction ), as a result of this more amount of  energy has to be initially and continuously supplied for them to overcome the activation energy barrier for the reverse reaction to occur and be sustained.

Using ideal gas law, the mass of helium in the laser is 1.5*10⁻³mg

To determine the mass of helium in the laser, we need to first calculate the number of moles of helium and neon in the laser. We can then use the molar mass of helium to convert the number of moles to mass.

Given that the laser has a volume of 0.785 L and is filled with a mixture of 90.0% helium and 10.0% neon at a pressure of 1.00 torr at 25.0 °C, we can use the ideal gas law to calculate the number of moles of each gas.

The ideal gas law is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

R = 8.314 J/mol.K

T = 25.0 + 273 = 298 K

Given that the pressure is 1.00 torr, we need to convert it to atm, which is the same unit as R.

1 torr = 1/760 atm

so, P = 1.00 torr / 760 atm = 0.0013158 atm

now we can calculate the number of moles of the gas in the laser:

n = PV / RT = 0.0013158 atm * 0.785 L / (8.314 J/mol.K * 298 K) =   4.17*10⁻⁷ moles

To find out the number of moles of helium and neon, we can use the percentage composition:

nHe = 4.17*10⁻⁷ moles * 90.0% = 3.753*10⁻⁷ moles

nNe = 4.17*10⁻⁷ moles * 10.0% = 4.17*10⁻⁸ moles

The molar mass of helium is 4.003 g/mol

We can use the number of moles and molar mass to find the mass of helium in the laser:

mass = nHe * molar mass =  3.753*10⁻⁷ moles * 4.003 g/mol = 1.5 *10⁻³mg

Therefore, the mass of helium in the laser is 1.5 * 10⁻³mg.

The substance, whose empirical formula is NO2 and whose molecular mass is 92 g/mol, has the molecular formula N2O4 (dinitrogen tetroxide).

Empirical formula is a compound's chemical formula that only specifies the ratios of the elements it contains and not the precise number or arrangement of the atoms. This would be the compound's element with the smallest whole number ratio.

molecular formula = empirical formula × n

where "n" is the total number of components required to construct a molecular formula.

molar mass of your compound is 92 g/mol (Given)

It implies that molar mass of every atom in that molecule must equal 92 g/mol.

1×14.0067 g/mol + 2×15.9994 g/mol = 46.0055 g/mol

So, if one building block has a molar mass of 46.0055 g/mol, how many would you need to get the molecule?

46.0055 g/mol × n = 92 g/mol

n = 92g/mol / 46.0055 g/mol = 1.99976 ≈ 2

either more or fewer neutrons than protons are there in an unstable isotope. Unstable isotopes do not occur in nature for long periods because they eventually break up.

Answer:

0.648 g of Ag ( silver) is produced

Explanation:

First calculating the moles of the reactants given;

Cu = 5/64 = 0.078 moles

Mr ( molecular mass) of AgNO3 = 108 + 14 + (16 x 3)

= 170 g

Now the moles of AgNO3 ;

1/170 = 0.006 moles

setting up mole ratio to calculate the limiting reactant:

moles of Cu  :  moles of Ag

       1            :     2

       0.078   :      X

X = 0.078 x 2

   = 0.156 moles of Ag

moles of AgNO3  : moles of Ag

             2            :      2

           0.006      :      X

X = (0.006 x 2)/2

   = 0.006 moles of Ag

As silver nitrate ( AgNO3) gives the least number of moles of Ag therefore it is the limiting reactant and would control the amount of product formed.

Now the mass of Ag formed:

atomic mass x moles

= 108 x 0.006

= 0.648 g of Ag ( silver) is produced

In order to find the rate of consumption of HCl in moles/s, you would need to know the balanced equation for the chemical reaction involving magnesium and HCl.

One common reaction is the reaction between magnesium and hydrochloric acid:

Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)

If the rate of consumption of magnesium is 5.0 × 10^-9 mol/s, this means that 5.0 × 10^-9 moles of magnesium are being consumed per second. In this reaction, one mole of magnesium reacts with 2 moles of HCl, so for every mole of magnesium consumed, 2 moles of HCl are also consumed.

Therefore, the rate of consumption of HCl in moles/s can be calculated by multiplying the rate of consumption of magnesium by 2:

rate of consumption of HCl = (rate of consumption of Mg) * 2

rate of consumption of HCl = (5.0 x 10^-9 mol/s) * 2 = 1.0 x 10^-8 mol/s

So the rate of consumption of HCl in moles/s is 1.0 x 10^-8 moles/s.

The volume of  1.33 mol/L calcium bromide solution that contains 125 g of calcium bromide is 470 mL

The volume can be calculate as follows:

First we should calculate the moles of calcium bromide

The moles of calcium bromide = Mass/ mass molar

The moles of calcium bromide = 125 g / 199.89 g/mol

The moles of calcium bromide = 0.625 moles

from de question we know that the molar of the solution is 1.33 mol/l

we also know that Molar = moles/ volume

so the volume is gonna be

volume= moles/ molar

volume = 0.625 moles/ 1.33 mol/L = 0.47 L = 470 mL

Therefore, the volume of  1.33 mol/L calcium bromide solution that contains 125 g of calcium bromide is 470 mL
