Answer: 112 dm3
Explanation:
At STP, 1 mole occupied 22.4dm3
Hence
5mole will occupy 22.4×5= 112dm3
I’m not sure but I think the answer is B
For every action there is an opposite and equal reaction. Your foot pushes on the boat and the boat pushes against the water which doesn't have much friction, so the boat moves backward instead of you moving forward. On land, the land pushes back up at you with the same force so you move forward.
Answer: -
The test solution reacted with the supernatant from the test tube. In trial number 3 there was the largest amount of precipitate.
An amount of 0.019 g of precipitate was found. In trial 3, 3 mL CuSO₄ and 3 mL Na₂S was taken. Thus they were at a 1: 1 ratio.
From the fact that the most amount of precipitate was formed when the two reactants were at 1:1 ratio implies that at that ratio, all of the reactants reacted.
Thus the mole ratio of the reaction is 1 : 1.
