How does the air masses and fronts play a role in a hurricane? Explain.
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.

Pure water boils at 100°C.
What happens to the water particles when water boils?
A They gain energy and move further apart.
B They gain energy and stay close together.
CThey lose energy and move further apart.
DThey lose energy and stay close together.
choose one answer correctly!
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.

Which of the following compounds would contain an electrostatic attraction as bonds between ions?
Answer:
iron sulfate
Explanation:
Electrostatic attraction as bonds between ions is characteristic of the electrovalent bond or the ionic bond
In this type of bond, there is electron transfer from one atom to another. The atom that looses electrons become positively charged while the atom that gains electrons becomes negatively charged.
In iron sulfate, there is electrostatic attraction between Fe II ions and sulphate ions, making iron sulfate an ionic compound.

How many moles of Ag (silver) contain 4.49 x 1023 atoms Ag?
27.0 mol
0.746E23 mol
0.746 mol
0.746E24 mol
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.

what is the amount of matter in an object.
A mass
B volume
C Density
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.
Hope this helps.

Calculate the mass of 120cc of nitrogen gas at ntp.How many number of molecules are present in it.Easy step of mole concept
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

It is more difficult to remove a proton from an atom than an electron. Which of the following force must be overcome to remove a proton from an atom? A) centrifugal force B) gravitational force C) electromagnetic force D) strong force
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
