<h2>
Answer: 4.94 g </h2>
Explanation:
Mass of solution of Na₃PO₄ = volume × density
= 35.9 mL × 1.10 g/mL
= 39.49 g
Now, since the solution only contains 12.5% Na₃PO₄, then the mass of Na₃PO₄ is 12.5% of 39.49 g
12.5% × 39.49 g = <u>4.94 g </u>
Answer:
false
Explanation:
it is MUCH lower in temperature
Answer:
In an endothermic reaction, the products have more stored chemical energy than the reactants. In an exothermic reaction, the opposite is true. The products have less stored chemical energy than the reactants. The excess energy in the reactants is released to the surroundings
Boyle's law gives the relationship between pressure of a gas and volume.
It states that the pressure of a gas is inversely proportional to volume of gas at a constant temperature.
PV = k
where P - pressure , V - volume and k - constant
P1V1 = P2V2
where parameters for the first instance are on the left side of the equation and parameters for the second instance are on the right side of the equation.
1.50 atm x 500.0 mL = P x 150.0 mL
P = 5 atm
applied pressure should be 5 atm to compress the gas.
