<h2>GREETINGS!</h2><h2>_____________________________________</h2><h3>Answer:</h3>

ITS $C_{4}H_{10}$ AND $C_{5}H_{12}$

<h2>_____________________________________</h2><h3><u>GENERAL FORMULA OF ALKANE</u></h3><h3> $C_{n}H_{2n+2}$ </h3>

Where n is the number of CARBONS

By using the General Formula of Alkanes having 4 carbon atoms is

$C_{4}H_{2x4+2}$

$C_{4}H_{10}$

By using the General Formula of Alkanes having 5 carbon atoms is

$C_{5}H_{2x5+2}$

$C_{5}H_{12}$

IF YOU USE THE SAME FORMULA FOR THE OTHER TWO OPTIONS THE OUTCOME WILL NOT BE AS SAME AS GIVEN IN THE QUESTION SO THOSE TWO ARE CAN NOT BE OUR ANSWER

Coal can be converted to methane gas by a process called coal gasification. The equation for the reaction is the following: 2 C

zloy xaker [14]

Answer:

24 g of C are needed to produce 1mol of CH₄

Explanation:

The reaction is:

2C (s) + 2H2O (l) → CH4(g) + CO2 (g)

2 moles of carbon react with 2 moles of water in order to produce 1 mol of methane and 1 mol of carbon dioxide.

If we want to produce 1 mol of methane, we need 2 moles of C

Let's find out the mass → 2 mol . 12 g/1 mol = 24g

Answer:

0.454moles

Explanation:

Calculate the molar mass of AgBr

Ag=108

Br=80

Molar mass= 108+80

Molar mass=188g/mol

It's mole to gram question

2moles of Na2S2O3= 188g of AgBr

X moles of Na2S2O3=42.7g of AgBr

Cross multiply

188x=2×42.7

X= 85.4/188

X=0.454moles

Acetic acid is the closest to 4.5 in my opinion.

Cl(g) + H2----> HCl(g) +H<br> Do interaction can occur at room temperature

Kaylis [27]

This is not the proper equation, the equation should be:
Cl2 + H2 ----> 2HCl
This does not happen at room temperature and needs a source of activation energy such a spark.
