Moles of K = 32.4/39 = 0.83 mole. According to stoichiometry, 2 moles of K produces 1mole of H2. Therefore, 0.83 mole of K produces = 0.83/2 = 0.415 moles of H2. Therefore number molecules of H2 = moles of H2 x 6.02 x 10^23 = 2.4983 x 10^23 molecules. Hope this helps!
Answer: Silver has an atomic mass of aproximately 107.9.
Explanation:
1 mole of silver atoms = 107.9g and there are 6.02x10^23 atoms in one mole.
Answer:
They are all organic compounds
Explanation:
Methanol, ethanoic acid and glucose are all organic compound that can be found in living organisms.
Glucose is a product of photosynthesis in plants. It is also produced from digestion of food in animals.
Ethanoic acid is a product of cellular respiration that occurs where there is insufficient oxygen.
Methanol is a waste often found in urine.
These compounds can all be traced to living sources. They are called organic compounds.
Answer:
Desmosomes.
From what I remember from my science class.
Answer: The new pressure is 2.8 atm.
Explanation:
Since our given information only involves pressure and volume, we will use Boyle's Law: 
. Let's input the data into the formula.
We have to rearrange our data a bit now because the volume is supposed to be in liters. To convert from milliliters(mL) to liters(L), you must divide the number by 1000. That is what we will do with both of our given volumes.
Now that our volumes are in liters, we can correctly plug in our data.
Since we do not know the value 
, we must rearrange the formula into a stoichiometric equation to find out the answer.
Our final answer is 2.8 atmospheres.
I hope this helps!! Pls mark brainliest :))
