Answer:

0.17094 liters

Explanation:

-For STP, Pressure=1 atm and Temperature=273K

-We apply the combined gas law which relates temperature, pressure and Volume:

\frac{PV}{T}=k

-We therefore equate the relationship at different temperatures as follows:

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}\\\\\frac{1\times 1.4\ }{273}=\frac{1.2\times V_2}{40}\\\\V_2=\frac{1\times 1.4\ }{273}\times \frac{40}{1.2}\\\\=0.17094\ L

Hence, the new volume is 0.17094 liters

In the reaction of silver nitrate with sodium chloride, how many grams of silver chloride will be produced from 100. g of silver
pantera1 [17]

Answer:

The mass in grams of silver chloride, AgCl produced is 84.37 grams

Explanation:

The chemical equation for the reaction is given as follows;

AgNO₃ + NaCl   →  AgCl + NaNO₃

The mass of silver nitrate, AgNO₃, in the reaction = 100.0 g

Therefore, 1 Mole of AgNO₃ produces 1 mole of AgCl,

The molar mass of silver nitrate, AgNO₃ = 169.87 g/mol

The number of moles of silver nitrate, AgNO₃, in the reaction = 100/169.87 moles

The number of moles of silver nitrate, AgNO₃, in the reaction ≈ 0.59 moles

Since 1 mole of AgNO₃ produces 1 mole of AgCl, 0.59 moles of AgNO₃ produces 0.59 moles of AgCl

The number of moles of silver chloride, AgCl produced = 0.59 moles

The molar mass of silver chloride, AgCl = 143.32 g/mol

Therefore;

The mass of silver chloride, AgCl produced = The number of moles of silver chloride, AgCl produced × The molar mass of silver chloride, AgCl

Which gives;

The mass of silver chloride, AgCl produced = 143.32 g/mol × 0.59 moles = 84.37 g

The mass of silver chloride, AgCl produced = 84.37 g.

If coefficients of a balanced equation are doubled the enthalpy change for reaction is
BlackZzzverrR [31]

Answer:

Explanation

ΔH is directly proportional to the quantity of a substance that reacts or is produced by a reaction. Enthalpy is directly proportional to mass. Therefore, if you double the coefficients in an equation, then the value of ΔH is multiplied by two.
