Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. Changing the pressure on a reaction which involves only solids or liquids has no effect on the rate.
Answer:
protons and neutrons
Explanation:
protons and neutrons is equal to mass number
Answer:
approx 2.45g
Explanation:
2HCl + Na2SO4 → 2NaCl + H2SO4
2 : 1 : 2 : 1
0.05 0.025 (moles)
⇒ mH2SO4 = 0.025 × 98 = 2.45 g
Answer:
Percentage error =
x 100%
Explanation:
In order to calculate the percentage error in the student's calculation, the following formula will be used:
Percentage error =
x 100%
experimental molar mass = 64 g/mol
theoretical molar mass = 58 g/mol
Hence, the expression becomes:
Percentage error =
x 100%
