Calculate how many moles of NH3 form when each quantity of reactant completely reacts according to the equation:
Leya [2.2K]
<span>1) Use the balanced chemical equation to find the molar ratios (proportions) of each product and reactant.

3N2H4(l)→4NH3(g)+N2(g)

=> molar ratios: 3 mol N2H4 : 4 mol NH3

2) Use the product to reactant molar ratio, and the quantity of reactant to determine the yield:

2.0 mol N2H4 * [4mol NH3] / [3mol N2H4] = 2*4/3 mol NH3 = 2.7 mol NH3

Answer: 2.7 mol

Butane (C4 H10(g), Delta. Hf = â€"125. 6 kJ/mol) reacts with oxygen to produce carbon dioxide (CO2 , Delta. Hf = â€"393. 5 kJ/mo
Anton [14]

The enthalpy of this reaction is -5315 KJ/mol.

The equation of the reaction is;

2C4H10(g) + 13O2(g) -----> 8CO2 (g) + 10H2O(g)

We know that the enthalpy of reaction can be obtained from the enthalpy of formation of the reactants and products as follows;

ΔHrxn = ΔHf(products) - ΔHf(reactants)

We have the following information from the question;

ΔHf C4H10 = - 125. 6 kJ/mol

ΔHf CO2 = - 393. 5 kJ/mol

ΔHf H2O = - 241. 82 kJ/mol

ΔHf O2 = 0 KJ/mol

Hence;

[(8 × (- 393. 5 )) + (10 × (-  241. 82))] - [2( - 125. 6))]

= -5315 KJ/mol

If more greenhouse gasses were added to the atmosphere, what would happen to Earth's heat budget and the planet's temperature?
denis23 [38]

Answer:

Global Warming!

Explanation:

Greenhouse gases help keeping the Earth warm for example; Carbon dioxide, methane etc. But recently there has been too much pollution which produced more greenhouse gases like; carbon dioxide...Usually trees and plants would help in keeping the air clean by eliminating carbon dioxide but as we know trees are being cut down. Which increases the amount of CO2 (chemical formula of Carbon dioxide) and they capture more heat. Which causes the temperature to gradually increase in earth and ice caps to melt in Antarctica, and causes the water levels to rise.
