Answer:

Step-by-step explanation:

a = 4

b= 1

c = 2

d =2

Leftside of equation:

No. of H molecules =  4

No. of Cl molecules =  4

No. of O molecules =  4  *4 + 8 =16 + 8 = 24

No. of P molecules = 2

Right side of equation:

No. of H molecules =  4

No. of Cl molecules =  4

No. of O molecules = 2*5 + 2 *7 = 10 + 14 = 24

No. of P molecules = 2

Clare is paid $90 for 5 hours of work. At thos rate how many seconds does i take for her to earn 25 cents?
natka813 [3]

We are given

Clare is paid $90 for 5 hours of work

Total money paid =$90

total hours of work =5 hours

so, firstly  we will find rate of work

rate of work = ( total money paid)/( total hours of work)

now, we can plug values

and we get

The rate of work is

=\frac{90}{5}

=18 $/ hour

now, we have to find time for amount paid is 25 cents

so, amount paid =25 cents

100 cents =1$

so, amount paid =$ 0.25

Since, the rate is constant

so, we can take same rate here

now, we can use formula

rate of work = ( total money paid)/( total hours of work)

now, we can plug values

18=\frac{0.25}{T}

now, we can solve for T

T=\frac{0.25}{18} hour

since, T is in hours

so, we can change into seconds

1 hour =3600seconds

so, we can plug

T=\frac{0.25}{18}\times 3600 seconds

T=50 seconds......................Answer
