Explanation:

The answer is when the waves meet the shore and cause the crest to spill over the trough. This activity creates a back and forth movement of the sand which causes them to settle at a certain area under below the water.

The boiling of pure water has been resulted in the particles gaining energy and moving away from each other. Thus, option A is correct.

The boiling can be described as the conversion of the liquid state to the gaseous state. The molecules in the gaseous space are apart from each other and have no fixed shape.

The pure water has been transferred to the gaseous state at the temperature of 100 degrees celsius. The boiling has been introduced with the addition of the energy.

The water molecules gain energy and start to vibrate. The vibrations have resulted in the change in the change in phase of the liquid with evaporation.

Thus, when pure water boils, the water particles gain energy and move away from each other. Thus option A is correct.

Answer:The Strong Nuclear Force (also referred to as the strong force) is one of the four basic forces in nature (the others being gravity, the electromagnetic force, and the weak nuclear force). As its name implies, it is the strongest of the four. However, it also has the shortest range, meaning that particles must be extremely close before its effects are felt. Its main job is to hold together the subatomic particles of the nucleus (protons, which carry a positive charge, and neutrons, which carry no charge. These particles are collectively called nucleons). As most people learn in their science education, like charges repel (+ +, or - -), and unlike charges attract (+ -).Hope this helps

Explanation:

took test edge 2020

D. 5

got it correct on test <3

C, 0.746 mol Ag.

1 mol Ag = 6.022 x 1023 atoms of Ag -> 4.49 x 1023 atoms of Ag x 1mol Ag/6.022 x 1023 atoms -> 0.746 mol Ag

The moles of Ag that contain 4.49  [tex]\rm \times\;10^2^3[/tex] atoms have been 0.745 moles.

The number of atoms in a mole can be given by the Avagadro number. The Avagadro number has been equal to the number of atoms in a mole of compounds. The Avagadro number has been constant with a value of 6.023 [tex]\rm \times\;10^2^3[/tex].  

6.023 [tex]\rm \times\;10^2^3[/tex] atoms = 1 mole

So, for the given 4.49  [tex]\rm \times\;10^2^3[/tex] atoms:

4.49  [tex]\rm \times\;10^2^3[/tex] atoms = [tex]\rm \dfrac{1}{6.023\;\times\;10^2^3}\;\times\;4.49\;\times\;10^2^3[/tex] moles

4.49  [tex]\rm \times\;10^2^3[/tex] atoms = 0.745 moles.

The moles of Ag that contain 4.49  [tex]\rm \times\;10^2^3[/tex] atoms have been 0.745 moles.

Answer:

Lead Phosphate

Explanation:

answer below

Explanation:

Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface.

Answer:

Option A

Explanation:

The answer is "mass" or option A. It's not option B because volume is the amount of space in a object which is not what the question is asking for. It's also not option C because density goes hand in hand with volume measuring how much space a object takes up, and also density is mass per volume. Leaving only option A, therefore it is your answer.

Percentage Composition from Formulas

A more complex example is sucrose (table sugar), which is 42.11% carbon, 6.48% hydrogen, and 51.41% oxygen by mass.

Or

53.3 %

Thus the % composition of glucose by mass is carbon 40.0 % oxygen 53.3 % hydrogen 6.7 % In this way, the % composition by mass of any compound can be calculated provided that its formula is known.

...

Carbon C 40.001%

Oxygen O 53.285%

Explanation:

The formula of nitrogen gas is given as;

          N₂

  Given volume of the gas = 120cm³

Now,

 We need to find the number of molecules and the mass of this compound

Solution:

At STP;

     1 mole of gas occupies a volume of 1dm³ ;

          1000cm³  = 1dm³

          120cm³  gives 0.12dm³;

Now;

              1dm ³ of gas contains 1 mole of substance at STP

             0.12dm³ will contain 0.12mole of nitrogen gas at STP

Mass of N₂ gas = number of moles x molar mass of N₂

    Molar mass of N₂ = 2(14)  = 28g/mol

    Mass of N₂  = 0.12 x 28  = 3.36g

1 mole of a substance contains 6.02 x 10²³ molecules

0.12 mole of N₂ will contain 0.12 x 6.02 x 10²³  = 7.22 x 10²²molecules
