Answer:
0.57 water
Explanation:
To solve this problem, we need to write the reaction expression first.
The reactants are oxygen gas and hydrogen gas.
They react to give a product of water
2H₂ + O₂ → 2 H₂O
Given that;
Number of moles of hydrogen gas = 0.57moles
From the balanced reaction expression;
2 moles of hydrogen gas produces 2 moles of water
So;
0.57mole of hydrogen gas will also produce 0.57 water
Answer:
6 J
Explanation: Work done(J) = Force(N) × Distance(m) along the direction of force.
Given, Force=2 N, Distance=3 meters
∴ Wok done (J) = 2 × 3 = 6 J.
Answer:
Water's heat of vaporization is around 540 cal/g at 100 °C. The same amount of heat is exchanged or released in the phase shift during the condensation of 1 g water vapor to 1 g of water.
