PLS HELP! VERY IMPORTANT ASSIGNMENT! 2. How many mol of HCl can form from 25.2 mol of Na 2 S 2 O 3 ? (2 marks)

3. How many Liters of Cl 2 are required to produce 15.7 moles of NaHSO 4 ? (2
marks)

4. How many molecules of HCl can form from 4.92 grams of H 2 O? (3 marks)

Pls show work and even if you can't answer them all even one answer would be appreciated

learn to pronounce

noun

the practice of taking someone else's work or ideas and passing them off as one's own.

step-by-step explanation:

d. you cannot tell because there are no values shown.

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
