Only CuSO4 conducts electricity in water because it is an ionic compound. The conduction of electricity is due to the ions in the ionic compound. When copper sulphate is dissolved in water, the ions dissociate and conduct electricity.
The others are do not liberate electricity when dissolved in water because ions are not liberated when electricity is passed through their solutions.

I would say CuSO4 or Copper Sulfate, as option 1 is Methane and would create a fire so heat, and the last one is Sugar which doesn't conduct electricity.  And C6H6 I believe is not soluble in water.<span />

36.4 g of SnCl2 is dissolved in 135.7 mL of water.
Yuki888 [10]

Answers:

1st: 189.6 g/mol

2nd: 0.1357 L

3rd: 1.41 M

Explanation:

Finding Molar Mass:

SnCl2 = <u>Tin(II) Chloride</u>

Tin has a molar mass of <u>118.71 g/mol</u>

Chloride has a molar mass of <u>35.453 g/mol</u>

Chloride*2 = <u>70.906</u>

<u>118.71 + 70.906 ≈ 189.6 g/mol</u>

Finding Liters of Solution:

L = mL/1000

135.7 mL / 1000 = <u>0.1357</u>

Finding Molarity:

molarity = <u>moles of solute / liters of solution</u>

M = (36.4g /  189.6g) / 0.1357 L = <u>1.41 M</u>

Hope this helped ;)

A 25.0 g sample of metal at
AveGali [126]

The answer to this question is change in temperature will be 6.1 and specific specific heat capacity of metal will be 1698.36.

According to the formula of Calorimetry

Q = msΔT

where, Q = Quantity of heat absorbed (in joules)

M = Mass of water sample given (in kilogram)

S = specific heat capacity of metal

ΔT = Change in temperature

We have given,

Mass as 25 gram which is equal to 0.025 Kg.

Change in temperature as 6.1

Quantity of heat absorbed as 259 J

Applying to the formula of Calorimetry

Q = msΔT

259 = 0.025 × s × 6.1

s = 1698.36

So, specific heat capacity of metal came out to be 1698.36 and the change in temperature will be 6.1
