Is this an example of decomposition 2CH4 + 402 → 2C02 + 4H2O

Chemistry
1 answer:
Molodets [167]3 years ago
5 0

Answer:

Identify each equation as a composition reaction, a decomposition reaction, or neither.

Fe2O3 + 3 SO3 → Fe2(SO4)3

NaCl + AgNO3 → AgCl + NaNO3

(NH4)2Cr2O7 → Cr2O3 + 4 H2O + N2

Solution

In this equation, two substances combine to make a single substance. This is a composition reaction.

Two different substances react to make two new substances. This does not fit the definition of either a composition reaction or a decomposition reaction, so it is neither. In fact, you may recognize this as a double-replacement reaction.

A single substance reacts to make multiple substances. This is a decomposition reaction.

Test Yourself

Identify the equation as a composition reaction, a decomposition reaction, or neither.

C3H8 → C3H4 + 2 H2

ithium metal reacts with water to give lithium hydroxide and hydrogen gas. if 75.5 mL of hydrogen gas is produce at STP, what is
Galina-37 [17]
The reaction equation may be written as:
2Li + 2H₂O → 2LiOH + H₂

A single mole of gas occupies 22,400 ml of gas at STP. Therefore, the moles of hydrogen gas are
75.5 / 22,400 = 0.0034 mol
According to the equation, the moles of lithium are twice that of hydrogen gas; thus,
0.0034 x 2 = 0.0068 mol

The mass of lithium is given by:
mass = moles x atomic mass
mass = 0.0068 x 6.9
mass = 0.047 grams

When you add the metal the volume increases from 25.0 to 28.9 how would you find the volume of the metal?
Rzqust [24]

3.9L

Explanation:

Initial volume = 25L

Final volume = 28.9L

The initial volume is the volume of the liquid without the metal in originally in the container. It is 25L

After adding the metal, the volume changes to 28.9L

 Final volume = Initial volume + volume of metal

To find the volume of metal make it the subject of the expression;

    Volume of metal = Final volume - initial volume = 28.9  - 25 = 3.9L

The volume of irregular solids are measured by immersing them in water. The change in volume gives their volume.

Sometimes the volume of water displaced is the volume of the solid.

When 40g of ammonium nitrate explode 14g of nitrogen and 8g of oxygen form. How many grams of water form?
blagie [28]

answer and Explanation:

the same amount would have to stay in grams, so if 14 grams of nitrogen is formed, then 8 grams of oxygen, add those two together and you get 22. and that's 22 of the 40 grams used, so 40 su
