<span>There are only four elements that were named after actual scientists.
Curium [Cm] is named after Marie and Pierre Curie. The Curies worked extensively on radioactive elements so another scientist appropriately named this radioactive element after them.
Einsteinium [Es] is named after the famed physicist Albert Einstein.
Lawrencium [Lr or Lw] is named after Ernest Lawrence, who invented a machine to detect radioactivity. Lawrencium is a radioactive element. Mendelevium [Md] is named after Dimitri Mendeleef who created the modern day periodic table.</span>
Answer:
Explanation:
Hello!
In this case, since the molarity of a solution is defined as the moles of solute divided by the volume of solution liters, given the mass of potassium sulfate, we can compute the moles by using its molar mass (174.24 g/mol):
Thus, since one mole of potassium sulfate has two moles of potassium ions (K₂) and one mole of sulfate ions, we can compute the moles of each ion as shown below:
In such a way, the molarity of each ion turns out:
Best regards!
Answer:
A reaction at equilibrium implies that the concentration/amount of reactants & products present in that reaction don't change but will remain constant. It could also mean that the forward reactions and reverse reactions will occur at the same rates.

Aluminum reacts with hydrochloric acid to produce aluminum chloride and hydrogen gas. 2 al(s) + 6 hcl(aq) → 2 alcl3(aq) + 3 h2(g) what mass of h2(g) is produced from the reaction of 1.35 g al(s) with excess hydrochloric acid?
Find 1 mol
6C = 12*6 = 72
12H=1*12 = 12
O6 = 16*6 = 96
Total = 180 grams
0.98 mol
0.98 * 180 = 176.40 My answer would have to go out to 176.40
Note: anyone responding will use rounded numbers for the atomic mass. All periodic tables have variations in them. Use your periodic table to get the better atomic mass.
Answer
176.40 g C6H12O6 <<<<
