I believe the correct answer here is 6.2. Since you would have to multiply the specific heat of gold by the amount of gold by the new heat of the gold. So this would be:

0.031 x 10 x 20 = 6.2

Hydrogen peroxide decomposes to form water and oxygen gas according to the following equation: 2H2O2(aq)  2H2O(l) + O2(g) If 31
olya-2409 [2.1K]

Answer:

141.89 dm^3

Explanation:

The equation of the reaction is;

2H2O2(aq) --------->2H2O(l) + O2(g)

Now , we are told that the mass of hydrogen peroxide decomposed was 315g. Number of moles of hydrogen peroxide in 315g of the substance is given by;

Number of moles= mass/molar mass

Molar mass of hydrogen peroxide= 34.0147 g/mol

Number of moles= 315g/34.0147 g/mol = 9.26 moles of hydrogen hydrogen peroxide.

From the reaction equation;

2 moles of hydrogen peroxide yields 1 mole of oxygen

9.26 moles of hydrogen peroxide yields 9.26 ×1/2 = 4.63 moles of oxygen

From the ideal gas equation;

Volume of the gas V= the unknown

Pressure of the gas P= 0.792 atm

Temperature of the gas= 23°C +273 = 296 K

Number of moles of oxygen = 4.63 moles of oxygen

R= 0.082atmdm^3K-1mol-1

Hence, from PV=nRT

V= nRT/P

V= 4.63 × 0.082 × 296/0.792 = 141.89 dm^3

During an experiment, 321.1 grams of strontium phosphite are measured into a beaker. How many moles of strontium phosphite are i
Allushta [10]

321.1 g of strontium phosphite will contain 0.76 moles of strontium phosphite in the beaker.

<u>Explanation:</u>

It is known that 1 mole of any substance is equal to the molar mass of that substance. So for the case of strontium phosphite, the molar mass is found to be 420.8 g/mol.

This means 1 mole of Strontium phosphite will contain 420.8 g of strontium phosphite.

Then 1 g of strontium phosphite will have \frac{1}{420.8} moles of strontium phosphite.

So, 321.1 g of strontium phosphite will contain \frac{321.1}{420.8}=0.76 moles

Thus, 321.1 g of strontium phosphite will contain 0.76 moles of strontium phosphite in the beaker.
