How much heat energy is produced when 22 grams of propane is burned in a stove?
To determine the heat energy produced when burning propane, we need to know its heat of combustion, which is approximately 50 MJ/kg. For 22 grams (0.022 kg) of propane, the energy released can be calculated as follows: 0.022 kg × 50,000 kJ/kg = 1,100 kJ. Therefore, burning 22 grams of propane produces about 1,100 kJ of heat energy.
How many grams of water are produced when 300 grams of hydrogen react with an unlimited amount of oxygen?
The atomic mass of hydrogen is 1.008 and the molecular mass of water, with formula H2O, is 18.015. Therefore, the mass of hydrogen to that of water has the ratio of 2(1.008)/18.015 = about 0.1119, and the answer to the problem is 300/0.1119 = 2.68 X 103 grams, to the justified number of significant digits.
What mass of water decomposes to make 4 grams of hydrogen gas and32 grams of oxygen gas how do you know?
In chemistry, the outcome of a reaction must have the same mass as the initial state. This means that if you have 32g of oxygen and 4g of hydrogen, you just have to add the numbers to discover the original mass (in this case, 36g).
How many grams of carbon dioxide is produced from the combustion of B grams of hexane?
The combustion of hexane (C6H14) produces carbon dioxide (CO2) according to the reaction: C6H14 + 7O2 → 6CO2 + 7H2O. For every 1 gram of hexane burned, approximately 3.03 grams of carbon dioxide are produced. Therefore, from the combustion of B grams of hexane, the amount of carbon dioxide produced would be approximately 3.03B grams.
What mass of methanol (CH3OH) is produced when 140.1 g of carbon monoxide reacts with 12.12 g of hydrogen?
8.20g of carbon monoxide, how many grams of methanol will be produced?
What is the total number of grams of H'S produced when 116 grams of the product Nail is formed?
The equation of the reaction is Fe + HCl → H₂ + FeCl₂. Since one mole of iron produces one mole of hydrogen gas, the molar ratio between Fe and H₂ is 1:1. Thus, the total number of grams of H₂ produced when 116 grams of iron is reacted would be 2 grams (1 mole of hydrogen gas weighs 2 grams).

How many grams of CO2 will be produced by burning 34.3 gram of C3H8?
To calculate the amount of CO2 produced when burning 34.3 grams of C3H8 (propane), you need to balance the chemical equation for the combustion of C3H8. Since each mole of C3H8 produces 3 moles of CO2, you first convert 34.3 grams of C3H8 to moles, calculate the moles of CO2 produced, and then convert that to grams of CO2.
How many grams of CO2 will be produced by burning 22 gram of C3H8?
To calculate the grams of CO2 produced by burning 22 grams of C3H8, first determine the moles of C3H8 using its molar mass, then use the balanced chemical equation for the combustion of C3H8 to find the moles of CO2 produced, and finally convert moles of CO2 to grams using the molar mass of CO2.
What weight and volume of carbon dioxide would be produced by burning 24 grams of carbon in air?
Weight:1.45 grams volume: 6.789

What is the number of grams of hydrogen gas produces when 146 grams of HCL decompose completely?
The gram molecular mass of HCl is 36.46 and the gram atomic mass of hydrogen atoms is 1.008. Therefore 146 grams of HCl decompose to provide 146(1.008/36.46) or about 4.04 grams of hydrogen gas, to the justified number of significant digits.
How many grams of hydrogen is produced when 167.12 g of hydrochloric acid is reacted with copper?
Cu + 2 HCl --> CuCl2 + H2 167.12 g HCl * (1 mol HCl/36.46 g HCl) * (1 mol H2/2 mol HCl) * (2.02 g/1 mol H2) = 4.629 g H2 4.63 grams of hydrogen gas is produced when 167.12 grams of hydrochloric acid reacts with copper.
In a laboratory 178.8 grams of water is separated into hydrogen gas and oxygen gasthe hydrogen gas has a mass of 20.0 grams what is the mss of the oxygen gas produced?
