<u>Answer:</u> The balanced equation for the above reaction is given below.

<u>Explanation:</u>

Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen to produce carbon dioxide and water molecule.

The balanced chemical equation for the combustion of methane follows:

CH_4+2O_2\rightarrow CO_2+2H_2O

By stoichiometry of the reaction:

1 mole of methane gas reacts with 2 moles of oxygen gas to produce 1 mole of carbon dioxide and 2 moles of water molecule.

Hence, the balanced chemical equation is given above.

Answer:

The correct answers are:

• Softer, porous, or more permeable rocks weather faster than harder rocks.

• Rocks in warmer climates weather faster than rocks in colder climates.

• The more water present, the faster the rate of weathering.

Explanation:

Weathering is the process through which the surface minerals of rock are broken down and loosened. This occurs through the action of extreme temperatures, rainwater and biological activity.

Hope this helps- Good luck ^w

Answer:

See explanation

Explanation:

Calcium carbide reacts with water to yield acetylene gas and calcium hydroxide as follows;

CaC2(s)+2H2O(g)⇋Ca(OH)2(s)+C2H2(g)

This now shows us that the equation as written in the question is wrong. Since the equation for the reaction of calcium carbide and water as shown in the question is wrong, the equation can not be balanced.

Volcanoes emit much hydrogen sulfide gas, h2s, which reacts with the oxygen in the air to form water and sulfur dioxide, so2. ev
liq [111]

Answer: There will be 131.3 tons of SO_{2} that will be generated.


Explanation : We have the data as 72 tons of H_{2}S, O_{2} is 101 tons and H_{2}O as 38 tons.


Conversion of 1 ton to kg will be approximately 907.2 Kg


We have to convert the given data of tons into kg for all;


So, moles of H_{2}S = (72 tons X 907.2 Kg/ton X 1000 g/Kg) / (34.082 g/ mol) = 1.916 X 10^{6} moles

Now, moles of O_{2} = (101 tons X 907.2 Kg/ton X 1000 g/Kg) / (32 g/mol) = 2.80 X10^{6} moles

And, H_{2}O = (38 tons X 907.2 Kg/ton X 1000 g/Kg) / (18.016 g/mol)

= 1.03 X 10^{6} moles


Now, we have to calculate the moles of H_{2}S

so, 1.916 X 10^{6} moles / 2 moles of H_{2}S = 958 X 10^{3}


Now, for O_{2} ;

So, 2.80 X10^{6} moles / 3 moles of O_{2} = 933.3 X 10^{3} moles


Here, we can see that O_{2} is acting as a limiting reactant.


Now, moles of SO_{2} = 2.80 X10^{6} X (2 moles of SO_{2} / 3 moles of O_{2}) = 1.86 X 10^{6}


Now converting this into mass,


Mass = Moles X Molar Mass

Mass = 1.86 X 10^{6} X (64.066 g/mol X 10^{-3} kg/g) X (1 ton / 907.2 Kg)

= 131.3 tons of SO_{2}
