Answer:

Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze.

so i'm gonna guess and say that it does not matter because the rain drops freeze in the atmosphere in a cold place.

Explanation:

Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze.

An atmosphere is defined as a blanket of gases that surrounds Earth which held near the surface of the planet by Earth’s gravitational force of attraction.

Argon, oxygen and nitrogen from the three main constituents of the atmosphere, it Helps to retain the sun’s heat and prevents it from escaping back into space, Protects life from harmful radiation, Plays a major role in Earth’s water cycle.

The atmosphere has five distinct layers which are determined by the changes in temperature and it happen with increasing altitude. Layers of Earth’s atmosphere are divided into five different layers as  Exosphere

Thermosphere, Mesosphere, Stratosphere, Troposphere

Answer:

according to online:

"Hydrogen ions are transported with the electrons along the chain of reactions. In photosystem I, the electrons are energized, and the energy is stored in molecules of NADP+. During these reactions, the NADP+ molecules are reduced by the addition of electrons. A hydrogen ion is added to NADP+ to form NADPH."

A) A plastic pot handle.

Metals are very good conductors of heat because they contain delocalised electrons that can flow through the metal, transferring heat.

Both a copper pan and a metal spoon are made of metals, so are very good conductors of heat.

Plastic is an insulator, the opposite of a conductor. This makes it very bad at conducting heat, which is why it is used as the handle (it stops you burning yourself when you hold the pot). The answer is therefore A.

What is the molar concentration of a solution prepared by dissolving 3.05 grams of sodium acetate in enough water to prepare 3.43 x 102 mL of the solution

sodium acetate NaCH3COO has molar mas of

23 + 12 +24 + 1 +32 = 92 g/mol

3.05 g is 3.05 g/ 92 g/mol = 0.0328 moles

it is distributed over 102 mL = 0.102 L

its concentration is 0.0328/ 0.102 =0.296 M Mhttps://brainly.com/question/25586315?answering=true&answeringSource=feedPublic%2FhomePage%2F3#

4NH₃(g) + 6NO(g) → 5N₂(8) + 6H₂O(l)

The mole ratio of NO to NH₃ based on the balanced equation is 6 to 4 (or 3 to 2 in the simplest form)

Therefore in the reaction, there are ³/₂ more moles of NO than NH₃.

⇒ since moles of NH₃ = 2.45 mol  

   then moles of NO    =   2.45 mol × ³/₂  

                                     =   3.675 mol

Answer:

cm^3 —> dm^3

divide by 1000

159.5 — Mr of CuSO4

n (moles in mol) = c (concentration in mol/dm^3) * v (volume in dm^3)

0.100 mol of CuSO4 dissolved in 0.5dm^3 of water

calculate for mass of CuSO4 dissolved in 0.03dm^3  (30cm^3) of the solution

n = m/Mr

m = n*Mr

if 0.1 mol is dissolved in 0.5 dm^3 of water

0.5/0.03 ≈ 16.66666667

0.1 = 0.05

0.1 / 16.66666667 = 0.006

0.5 / 16.66666667 = 0.03

0.006 (mol of CuSO4) = 0.03 (dm^3 solution)

0.006 * 159.5 = 0.957 g

I think this is the answer

The mass copper sulphate CuSO₄ in 30ml solution is 957.6g.

To determine the mass of copper sulphate in the given solution, compare both the molarity given  

M₁V₁=M₂V₂

n₁/V1=n₂/V2

0.1/0.5=n₂/30         cm³=ml

n₂=6 moles

6×159.5=957.6g

Multiply the calculated moles with the relative mass/molecular mass to get the mass of CuSO₄.

hence, the mass of CuSO₄ is 957.6g
