Explanation:
According to law of conservation of mass, mass of the reactants is equal to the mass of products in a chemical equation. As mass can neither be created nor it can be destroyed but it can be transformed from one form to another.
As it is given that hydrogen and in excess oxygen is reacting that leads to the formation of water. Hence, the chemical reaction equation will be as follows.
Since, it is given that 4 mol of hydrogen is reacting with excess of oxygen and gives 2 moles of water.
Hence, number of moles of water produced is calculated as follows.
4 mol of 
= 4 moles of 
Thus, we can conclude that 4 moles of water you can produce from 4.0 mol of hydrogen and excess oxygen.
They show equal response to every kind of taste , doesn't matter if sour , salty , sweet , pungent etc . that depends on what the person likes the most , if you like sugary edibles , then the brain would sense it and be happy about it , and show a greater tendency towards it.
Molarity refers to moles/ L. This indicates the concentration of a solution containing solute and solvent.
1 molar solution contains 1 mole of solute in 1 L of solvent.
According to Avogadro's number, 1 mole of a substance contains 6.023 x 10^23 molecules, atoms, or ions.
For this reason, 6.023 x 10^23 atoms, ions, or molecules are in a molar solution.
You have to balance out those forces and apply the same amount of equal and opposite force to it. I hope I helped ^^
Answer:
There is no friction because of the mass.
Explanation:
The bigger box ran out of force to move so it hit the smaller box. (im in 7th grade and have the answer key)
