A4% peroxide solution is mixed with a 10% peroxide solution, resulting in 100 l of an 8% solution. the table shows the amount of each solution used in the mixture. what is the value of z in the table?

its 8

Step-by-step explanation:

100x0.08=8

plus i took the test on edg -_-

Step-by-step explanation:

Let x represent the amount of 4% solution and y represent the amount of 10% solution.

⇒ x + y = 100 ..................(1)

x liters of the 4% solution gives us the expression 0.04·x

y liters of the 10% solution gives us the expression 0.10·y

100 L of the 8% solution gives us 0.08 × (100) = 8

⇒ 0.04·x + 0.10·y = 8 ...........(2)

This gives us the system of equations (1) and (2)

To solve this, we will use substitution.

Substituting x = 100 - y from equation (1) into equation (2). We get,

Substitute this value of y into the first equation:

use formula for the circle a=3.14

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
