Acetylene gas, C2H2, releases large quantities of heat when it burns, making it ideal for welding applications. This gas is gene

rated by reacting calcium carbide with excess water. Calcium hydroxide is a byproduct of this reaction. If you needed 26kg of acetylene to fill a cylinder, how many kg calcium carbide would you need to order?

Answer:

64 kg

Explanation:

The computation of the number of kg need to ordered is shown below:

As we know that

CaC_2 + 2H_2O \rightarrow Ca(OH)^2   + C_2H_2

Now as we know that

1  mole of C_2H_2 generated from 1 mole of CaC_2

Now

26g of C_2H_2 generated from 64g of CaC_2

And,

26kg of C_2H_2 generated from

= \frac{64g\times26Kg}{26g}

= 64kg CaC_2

Hence, the number of kg that required for ordering the calcium carbide is 64 kg

<u>Answer:</u>

a. Oxidising agent: Cl₂

b. Reducing agent: NaBr

c. Oxidised: NaBr

d. Reduced: Cl₂

e. Oxidation numbers before reaction: Cl= 0, Na= +1, Br= -1

f. Oxidation numbers after reaction: Cl= -1, Na= +1, Br= 0

<u>Explanation:</u>

Oxidising agents reduces themselves, oxidising other elements/compounds.

Reducing agents oxidise themselves, reducing other elements/compounds.

Oxidation is the <u>loss</u> of electrons or an <u>increase</u> in oxidation number.

Reduction is the <u>gain</u> of electrons or <u>decrease</u> in oxidation number.

Suppose that a sample of gas occupies 187 mL
drek231 [11]

Answer:

V2 = 90.7 mL

Explanation:

pressure and volume are inversely proportional, if the pressure is increased, the volume will decrease. In an isothermal process:

p1V1 = p2V2

V2 = p1V1/p2 = (277 torr×187 mL)/571 torr

V2 = 90.7 mL
