Answer:
4.3 x 10⁶ kJ are released
Explanation:
From the balanced chemical equation we know that when 2 moles of hydrogen peroxide decompose, 191 kJ of heat are released. So what we need to calculate is the number of moles the 765 kg of H2O2 represent and calculate the heat released.
Molar Mass H2O2 = 34.01 g/mol
Mass H2O2 = 765 Kg x 1000 g/Kg = 765000 g
moles H2O2 = 1 Mol / 34.01 g x 765000 grams = 22.5 Mol
(-196.1 kJ/ 2 mol H2O2 ) x 22.5 mol H2O2 = -4.3 x 10⁶ kJ
<span>The equation that represents the pressure of a gas under ideal conditions is the PV= nRT. The pressure of a gas is the exerted force that has various properties such as the compressibility and the viscosity. Compressibility refers to the response actions when pressure is applied.</span>
98.857g Na
To find this, set up an equation as so:
4.3 mol Na = 
Multiply everything on the top and divide that by everything on the bottom to get the final answer of 98.857g Na.
Hope this helps!
