Answer:
C
Explanation:
Pressure it says it in the name its the force of colliding particles
<h3><u>Answer;</u></h3>
= 9.45 × 10^23 molecules
<h3><u>Explanation; </u></h3>
The molar mass of Na2SO4 = 142.04 g/mol
Number of moles = mass/molar mass
= 223/142.04
= 1.57 moles
But;
1 mole = 6.02 × 10^23 molecules
Therefore;
1.57 moles = ?
= 1.57 × 6.02 × 10^23 molecules
<u>= 9.45 × 10^23 molecules </u>
Answer:
Ratio between the reactants is 1:1, so if 2 moles of potassium sulfate react, The reaction consumes 2 moles of barium chloride
The reaction produces 2 moles of barium sulfate ( ratio is 1:1) and 4 moles of potassium chloride. (Ratio with this is 2:4)
Explanation:
This is the reaction:
BaCl₂(aq) + K₂SO₄(aq) → BaSO₄(s) + 2KCl(aq)
Ratio between the reactants is 1:1, so if 2 moles of potassium sulfate react, The reaction consumes 2 moles of barium chloride
The reaction produces 2 moles of barium sulfate ( ratio is 1:1) and 4 moles of potassium chloride. (Ratio with this is 2:4)
Answer:
"To ensure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance."
Explanation:
Hello,
The OSHA -Occupational Safety and Health Administration- is an agency of the United States Department of Labo signed into law on December 29, 1970.
