Question

I need help with these science questions, leave explanations please.

Answer 1

Hello there.

Which acid will undergo 100% dissociation when dissolved in water?

Answer: HCL

Option: C

Second Question...not sure.

Answer 2

1.

Answer:

C) HCL

Explanation:

here HCL is 100% dissolved in the water because electronegativity difference between H and CL is sufficiently high and it will easily dissociate the charge into two ions.

So here correct answer will be

C). HCL

2.

Answer:

A) 2

Explanation:

Electrical power is defined in terms of current and resistance as

$P = i^2R$

now we will have current is doubled but resistance is halved

so change will be given as

$P' = (2i)^2(\frac{R}{2})$

so we have

$P' = 2P$

so here power is doubled
