Answer:

Naphthalene is a non polar substance

Explanation:

In chemistry, the principle of like dissolves like is the over aching principle that controls the dissolution of one substance in another.

Naphthalene dissolves in diethyl ether because diethyl ether is a non polar solvent just as naphthalene is a nonpolar substance.

Since water is a polar solvent, it can not dissolves naphthalene at any pH because naphthalene is a nonpolar substance.

Calcium hypochlorite (ca(ocl)2, mw = 142.983 g/mol) is often used as the source of the hypochlorite ion (ocl–, mw = 51.452 g/mol
stiv31 [10]
When the concentration is expressed in ppm, that means parts per million. It is also equivalent to mg/L. For this problem, we do stoichiometric calculations. We manipulate the units by cancelling like units if they appear in the numerator and denominator side until we come with the amount of solid Ca(OCl)2 needed. The solution is as follows:

40 mg/L * (1 L/1000 mL) * 50 mL * (1 g/1000 mg) * (1 mol OCl⁻/51.452 g) * (1 mol Ca(OCl)₂/ 2 mol OCl⁻) * (142.983 g Ca(OCl)₂/mol) * 0.95 = 2.64×10⁻3 g or 2.64 mg.

Therefore, you would need 2.64 mg of solid Ca(OCl)₂.

HELP!!!
Helen [10]

Answer:

The answer to your question is 8.1 g of ZnCl₂

Explanation:

Data

mass of ZnCl₂ = ?

mass of Zn = 7.0 g

mass of CuCl₂ = 8 g

Balanced chemical reaction

                Zn  +  CuCl₂   ⇒   ZnCl₂  +  Cu

Process

1.- Calculate the molar mass of the reactants

Zn = 65.4 g

CuCl₂ = 63.6 + (35.5 x 2) = 134.6 g

2.- Calculate the limiting reactant

theoretical yield  CuCl₂ / Zn = 134.6/65.4 = 2.06

experimental yield CuCl₂ / Zn = 8/7 = 1.1

The limiting reactant is CuCl₂ because the experimental yield was lower than the theoretical yield.

3.- Use proportions to calculate the mass of ZnCl₂

molar mass of ZnCl₂ = 65.4 + (35.5 x 2) = 136.4 g

                  134.6 g of CuCl₂ ---------------- 136.4 g of ZnCl₂

                      8   g                 ----------------  x

                      x = (8 x 136.4) / 134.6

                      x = 8.1 g of ZnCl₂

PLEASE HELP IM SO CONFUSED :(
Ksenya-84 [330]
Answer is: 2Zn + O₂ → 2ZnO (2Zn²⁺ + 2O²⁻).
Unbalanced chemical reaction: Zn + O₂ → ZnO.
Zn → Zn²⁺ + 2e⁻ / ×2; 2Zn → 2Zn²⁺ + 4e⁻.
4e⁻ + O₂ → 2O²⁻.
Zinc lost two electrons and became Zn²⁺, molecule of oxygen gain four electrons and become 2O²⁻.  Multiply first reaction with two to have same number of electrons and put coefficients in chemical reaction.

How many phosphorus atoms are contained in 158 kg of phosphorus? how many phosphorus atoms are contained in 158 kg of phosphorus
zheka24 [161]
To determine the number of phosphorus atoms from a given mass, we need to determine the number of moles of the substance by dividing the molar mass which for in this case is equal to 123.88 g/mol for P4. Then, we multiply Avogadro's number. It <span>represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole.

mole P4 = 158 kg P4 ( 1000 g / 1 kg ) ( 1 mol / 123.88 g ) = 1275.43 mol P4
# of P4 atoms = 1275.43 mol P4 ( 6.022 x 10^23 atoms P4 / 1 mol P4 ) = 7.68x10^26 atoms P4</span>
