Answer:liters
Explanation:
Refer to the following balanced equation in which ammonia
reacts with nitrogen monoxide to produce nitrogen and
water.
4NH3(g) + 6NO(g) → 5N2(8) + 6H2O(l)
How many moles of NO are required to completely react with
2.45 mol NH3 ?
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

Which ingredients are needed to transform nadp to nadph?.
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."

what is atmosphere ?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

Which of the following is NOT a conductor of heat?
A. a plastic pot handle
B. a copper pan
C. a metal spoon
A) A plastic pot handle.
Explanation: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.

Explanation:
A copper sulphate solution contained 0.100 moles of copper sulphate dissolved in 0.500 dm cubed of water. Calculate the mass of copper sulphate in 30.0cm cubed of this solution. Relative formula mass (mr): CuSO4= 159.5
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.
How to determine the mass of copper sulphate in the given solution?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

125 mm Hg. What will the new pressure be when the volume
is decreased to 2.75 L? The temperature stays the same.
Answer:

The new pressure can be found by using the formula for Boyle's law which is
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume

why are water-soluble vitamins less likely to be toxic compared to fat-soluble vitamins?
Answer:
Water-soluble vitamins are not stored in the body and are excreted in the urine quickly. Unlike water-soluble vitamins, fat-soluble vitamins are dissolved in fat and an excess of them would lead to toxicity if consumed in large amounts because it would lead to rancidity, and they are not easily excreted by urine like water-soluble vitamins.
Even when consumed in high doses, water-soluble vitamins are less likely to create problems since they are eliminated through urine rather than stored.
What are vitamins?Vitamins are defined as a collection of molecules required for healthy cell growth, development, and function. While some vitamins support healthy neurons and infection resistance, others may aid in correct blood clotting or food energy absorption.
Water-soluble vitamins are promptly eliminated in the urine and are not retained by the body. In contrast to water-soluble vitamins, which are easily eliminated by urine, fat-soluble vitamins are dissolved in fat. If ingested in excess, they can be harmful due to rancidity and cannot be easily expelled through urine.
Thus, even when consumed in high doses, water-soluble vitamins are less likely to create problems since they are eliminated through urine rather than stored.
