The answer will be D that is electricity is a flow of protons.

Electricity has the following properties:

It is a flow of electrons.

It travels easily through metal.

It travels "downhill" as it is attracted to the Earth.

So the answer is D only as electricity is not a property of protons , it is not a flow of protons, electricity is only defined as flow of electrons not protons so the answer is D only.

D, It is a flow of protons, is the best answer. Electricity is the flow of electrons, not protons.

Calculate the percentage composition of each element in calcium hydroxide
sp2606 [1]

Answer:

54.1 % Ca, 43.2 % O, 2.7% H

Explanation:

Molecular formula for calcium hydroxide is Ca(OH)₂

As we don't have a mass of Ca(OH)₂ to find out the percentage composition, we consider that the question refers to 1 mol of compound.

1 mol of hydroxide weighs 74.08 g

1 mol of hydroxide has 1 mol of Ca, therefore 40.08 g are Ca

2 moles of O therefore 32g are O

2 moles of H therefore 2 g are H

Percentage composition is known as (Mass of element/Total mass) . 100

  • (40.08 / 74.08) . 100 = 54.1 %
  • (32 / 74.08) . 100 = 43.2 %
  • (2 / 74.08) . 100 = 2.7%

In order to complete his research project, Roger needs to make a mixture of 86 mL of a 36% acid solution from a 39% acid
Zina [86]

The volume of the 39% acid solution that Roger needs to use to make a mixture of 86 mL of a 36% acid solution is 74.27 mL.

The mixture of the acids solutions is given by:

CV = C_{1}V_{1} + C_{2}V_{2}    (1)      

Where:

C: is the concentration if the mixture = 36%  

V: is the total volume of the mixture = 86 mL

C₁: is the concentration of acid 1 = 39%

V₁: is the volume if acid 1 =?

C₂: is the concentration of acid 2 = 17%

V₂: is the volume of acid 2

The sum of V₁ and V₂ must be equal to V, so:

V = V_{1} + V_{2}

V_{2} = V - V_{1}  (2)

By entering equation (2) into (1), we have:

CV = C_{1}V_{1} + C_{2}(V - V_{1})

36\%*86 mL = 39\%*V_{1} + 17\%(86 mL - V_{1})

Changing the percent values to decimal ones:

0.36*86 mL = 0.39*V_{1} + 0.17(86 mL - V_{1})  

Now, by solving the above equation for V₁:

V_{1} = 74.27 mL  

Therefore, the volume of the 39% acid solution is 74.27 mL.

PLEASE HELP
WITCHER [35]
The answer is A) Water has surface tension.
This is the correct answer because water allows animals and really light items to rest upon the top of the water. 
Hope This Helps! If you could mark me as the brainiest answer, that would be amazing. I want others to read this answer and know it is accurate. If you need help with another question, just ask. :)
