<em>D</em> = 1.59 g/mL  = 1.59 kg/L

Mass of CCl₄ = 703.55 g – 346.8 g = 357.75 g

<em>D</em> = mass/volume = 357.75 g/225 mL = 1.59 g/mL

(1.59 g/1 mL) × (1 kg/1000 g) × (1000 mL/1 L) = 1.59 kg/L

The compound has the empirical formula of CH. Give some possible molecular formulas for this compound if you didn't know the mol
olchik [2.2K]

Answer:

Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. This is the mole ratio of the elements and is represented by subscripts in the empirical formula.

Explanation:

The result is the molecular formula

What causes water's low vapor pressure?
kenny6666 [7]
"The vapor pressure<span> of water is relatively </span>low<span> because it is held together through hydrogen bonds. This means that the molecules in a glass of water do not evaporate from the water very easily, as the molecules are attracted to each other."</span>

Write the rate expression for the following reaction. H2+1/2 <br>O2 arrow H2O​
julsineya [31]

Answer:

r=-k[H_2][O_2]^{1/2}

Explanation:

Hello!

In this case, according to the chemical reaction:

H2 + 1/2  O2 --> H2O​

Since both hydrogen and oxygen are the reactants and the rate laws are written in terms of the concentration of reactants and the rate constant, we obtain:

r=-k[H_2][O_2]^{1/2}

Whereas the negative sign represents the consumption of those reactants and the power 1/2 the stoichiometric coefficient of oxygen in the reaction.

Best regards!
