Ineed with these science questions, leave explanations .

which acid will undergo 100% dissociation when dissolved in water?
a c25cooh
b ch3cooh
c hcl
d hf

a parallel dc circuit has a total current of 4 amperes and a resistance of .5 ohms. if the current is doubled, and the resistance is halved, how many times more is the new power compared to the old power?
a 2
b 4
c 1/4
d 1/2

1.

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.

A) 2

Explanation:

Electrical power is defined in terms of current and resistance as

now we will have current is doubled but resistance is halved

so change will be given as

so we have

so here power is doubled
