Answer:
-219.99kJ
Explanation:
The acronym '' NADH'' simply stands for what is known as coenzyme 1 with full meaning of Nicotinamide Adenine Dinucleotide Hydride. This substance is useful in the production of energy. The oxidation reaction of NADH causes it to produce NADP⁺ and the oxygen produces water when it is in the reduction process. The balanced equation for the oxidation reaction is given below as:
NADPH ---------------------------------------------------------------------> NADP⁺H⁺ + 2e⁻.
Also, the balanced equation for the reduction reaction is given below as:
O₂ + 2H⁺ + 2e⁻ --------------------------------------------------------------> H₂O.
It can be shown from the above REDOX reaction that the total number of electrons getting transferred is 2.
The Gibbs energy = -nFE. where n = 2, F = faraday's constant = 96485.3329 C and E = overall cell potential.
The overall cell potential = E[ reduction reaction] - E[oxidation reaction] = 0.82 - (- 0.32 ) = 1.14 V.
Hence, the Gibbs energy = - 2 × 96485.3329 × 1.14 = -219.99kJ
Be 2+ is the charged ion of Be
-same amount of protons and neutrons, but has 2 less electrons, giving it full valence shell and + 2 charge
Answer:
A very high powered nuke.
Explanation:
The sheer force,as used in "Armageddon",will have to be more powerful than Tsar Bomba,the largest nuclear bomb to detonate in history.In order to make this bomb,you would need a <u>lot</u> of nuclear fission.This is a delicate process,so we must do it carefully,but not too slowly.Next:The detonation.It would either have to be rocket powered to the asteroid cluster,asteroid,etc,or it would have to be transported.Once near the target,it would have to be remote detonated from a far distance,because radiation travels FAST through space,therefore,if not a far enough distance away,you would melt into nothing,probably.Once detonated,there are multiple possibilities,the rock could split in half and go separate ways around the earth,reattach,and keep going.Or maybe the bomb would do nothing and just put another crater in the asteroid,and we all die.There are way more,but to the point,a nuclear bomb has a 50% chance of working,but its the best way.
The mass, in grams, of the chlorine gas will be 0.84 grams
<h3>Mass of gases at STP</h3>
At standard temperature and pressure, 22.4 L of gas has 1 mole of the gas in it.
This time, what we have is 265 mL of the gas at STP. 265 ml is equivalent to: 265/1000 = 0.265 L
If.
22.4 L = 1 mole
Then,
0.265 L = 0.265 x 1/22.4 = 0.01183 moles
This means that 0.01183 moles of chlorine is present in the gas at STP.
Mass of 0.01183 moles of chlorine = moles x molar mass.
The molar mass of chlorine gas is 71
Mass of the chlorine gas = 0.01183 x 71 = 0.84 grams

#SPJ1
The heat required to completely melt the given substance, platinum, we just have to convert first the given mass in mole and multiply the answer to its molar heat of fusion..
Hf = mass x (1/molar mass) x molar heat of fusion
Hf = (85.5 g) x (1 mole/195.08 g) x 4.70 kcal/mol
Hf = 2.06 kcal
