If you burn 22.6 g of hydrogen and produce 202 g of water, how much oxygen reacted

Chemistry

Jlenok [28]3 years ago
8 0
The balanced reaction for the production of water from hydrogen and oxygen is: 2H₂ + O₂→ 2H₂O. Also, the relevant molar masses are the following:

Molar mass of H₂O = 18 g/mol
Molar mass of O₂ = 32 g/mol

We need not be concerned with the amount of hydrogen since we can derive the amount of oxygen that reacted based on the amount of product produced. The following equation is then set-up:

Mass of O₂ reacted = <span>202 g H2O x 1 mol H2O/ 18 g H2O x 1 mol O2/ 2 mol H2O x 32 g O2/ 1 mol O2 = 179.56 g O2

Thus, we have determined that 179.56 g O2 reacted with H2 to produce 202 g of H2O.</span>

At STP, what volume of container would be needed to hold 3.2 moles of gas?
Rzqust [24]

78.4 L volume of container is required to hold 3.2 moles of gas.

Explanation:

  • STP is defined as the standard temperature and pressure of a gas in room temperature conditions. At STP, one mole of the gas which has Avogadro's number of molecules in it will occupy a volume of 22.4 L.
  • So, one mole of a substance or gas will occupy a volume of 22.4 L then the volume of the container needed for  3.2 moles of gas is calculated by multiplying 22.4 L, standard volume with the moles of the gas 3.2 moles.
  • Hence, the answer would be 78.4 L.

An object on top of a building has a GPE of 23,048j and a mass of 39kg, What is the height of the object
kirill115 [55]

Answer:

<h2>59.1 m</h2>

Explanation:

The height of the object can be found by using the formula

h =  \frac{p}{mg }  \\

where

p is the potential energy

m is the mass

h is the height

g is the acceleration due to gravity which is 10 m/s²

From the question we have

h =  \frac{23048}{39 \times 10}  =  \frac{23048}{390}  \\  = 59.0974...

We have the final answer as

<h3>59.1 m</h3>

Hope this helps you
