The appropriate mixing ratio for a solution to kill blood borne pathogens is 1 part chlorine to 10 parts water if you are mixing a solution in a spray bottle with 15 ounces of water how much chlorine do you need to add for the correct ratio

To solve this problem, all we have to do it to make use of the principle of ratio and proportion. We are given the following ratio:

1 part Chlorine / 10 parts Water

Now to determine the amount of chlorine needed for 15 ounces of water, all we have to do is to use proportion. Let us say that the amount of Chlorine needed is x, therefore:

1 part Chlorine / 10 parts Water = x / 15 ounces Water

so,

1 / 10 = x / 15

Therefore calculating for x:

x = 15 / 10

x = 1.5 ounces of Chlorine

let that person have a turn to speak : )

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
