3.
protium (A = 1), deuterium (A = 2), and tritium (A = 3).
Answer:
Lavoisier made an important contribution to chemistry by the law of conservation of mass
Explanation:
The law of conservation of mass tell us, that the mass doens't change in a system. You have the same mass at the begining and in the end of a reaction.
Matter is neither created, nor destroyed in a chemical reaction.
This law also states that mass of reactants is the same of products in any chemical reaction
the correct answer is.. ill tell you when i search it up gimme 2 seconds
<span>C represents the displacement ONLY if it is the VECTOR arrow from P to W.
Usually if the arrow on the diagram has JUST a letter listing, that letter stands for the SIZE or LENGTH of the VECTOR arrow. In order to have the letter represent the VECTOR, itself, it must have a symbol of a "half arrow" placed above it.</span>
Answer:
A solution labeled "0.105 M NaOH" would contain 0.105 moles of NaOH in each liter of solution.
Explanation:
The concentration of a solution in Molarity (M) stands for the number of moles of that substance contained in 1 L of solution.
Molarity = Concentration in mol/L = (Number of moles of solute) ÷ (Volume of solution in L)
Molarity = Concentration in mol/L = 0.105 M = 0.105 mol/L
Number of moles of solute = ?
Volume of solution in L = 1 L
0.105 = Number of moles of solute × 1
Number of moles of solute = 0.105 mole
Hence, a solution labeled "0.105 M NaOH" would contain 0.105 moles of NaOH in each liter of solution.
Hope this Helps!!!
