Explanation:
Your tools of choice for stoichiometry problems will always be the mole ratios that exist between the chemical species that take part in the reaction.
As you know, the stoichiometric coefficients attributed to each compound in the balanced chemical equation can be thought of as moles of reactants needed or moles of products formed in the reaction.
In your case, the balanced chemical equation for this synthesis reaction looks like this

Notice that the reaction requires
2
moles of hydrogen gas and
1
mole of oxygen gas to produce
2
moles of water.
This tells you that the reaction produces twice as many moles of water as you have moles of oxygen gas that take part in the reaction.
You know that your reaction uses
6.0
moles of oxygen. Assuming that hydrogen gas is not a limiting reagent, you can say that the reaction will produce
6.0

Answer:
[NaCl] = 1.72 M
Explanation:
First of all, we balance the equation:
BaCl₂ + Na₂SO₄ → 2NaCl + BaSO₄
We convert mass of barium chloride to moles
45 g . 1mol / 208.23g = 0.216 moles
Ratio is 1:2. This means, that our moles of reactant may produce the double of moles, of product.
0.216 . 2 = 0.432 moles of NaCl are been produced.
Molarity is mol/L. We convert volume of water from mL to L
250 mL . 1L /1000 mL = 0.250 L
[NaCl] = 0.432 mol/0.250L = 1.72 M
<span>Our Earth is structured around the densities of the materials which make it up.One property of density is that it determines the way materials in a mixture are sorted. This property of matter results in the layering and structure of Earth's atmosphere, water, crust, and interior.</span>
Answer: density or
To determine the toughness of a solid you would have to know how much kinetic energy it absorbed before it broke.
