Answer:

increases

Explanation:

The acid strength of any species depends on the stability of its conjugate base ,

The conjugate base is formed via the removal of the hydrogen ion .

Hence , more stable the conjugate base , more acidic would be the compound .

The conjugate base have a negative charge ,

Hence , larger the anion or the conjugate base , more stable it would be , because the negative charge will get dispersed on the larger species , hence will become stabilized .

Therefore ,

Larger the size of anion or the conjugate base , more stable would be the anion and more acidic would be the compound .

Aneli [31]
The correct answer is <span>A. The transfer of heat and energy

Sound waves, electron movement, and conservation of matter are studied by different parts of physics. Thermo is an ancient root word/prefix that is used to refer to heat. An example of that is a Thermos, which is supposed to save heat of a liquid.</span>

Semenov [28]
I think it’s C since the ice changes from solid to a liquid which is physical and then it reacts with calcium metal making the calcium hydroxide which is chemical change. And another sign of it being chemical was the release of gas.

A sunscreen preparation contains 2.50% benzyl salicylate by mass. If a tube contains 4.0 oz
antoniya [11.8K]

About 0.92 kg of benzyl salicylate would be needed in order to manufacture 325 tubes of sunscreen.

A tube contains 4.0 oz of the sunscreen and each one 2.5% benzyl salicylate.

         2.5% of 4.0 oz = 0.1 oz

Thus, each tube would need 0.1 oz of benzyl salicylate.

325 tubes of the sunscreen is needed and each one requires 0.1 oz of benzyl salicylate. Hence, total amount of benzyl salicylate needed would be:

    325 x 0.1 oz = 32.5 oz

From conversion:

16 oz = 1 lb

Hence,

32.5 oz = 32.5/16

                        = 2.03 lb

Also:

2.205 lb = 1 kg

2.03 lb = 2.03/2.205

             = 0.92 kg
