Northern atlantic and northern pacific oceans
Answer:
25.5 g
Explanation:
First, you will need a balanced chemical equation
CuO + H₂ ==> H₂O + Cu
From the equation above, we can see that for every 1 mole of CuO (copper(II) oxide), 1 mole of Cu (copper) is produced.
Convert grams of CuO to moles. You should get 0.402 mol. Now with the relationship established above, you can see that you should ideally get 0.402 mol. Convert this to grams. Your answer should be 25.5 g.
Answer:
Carbon dioxide is a gas at room temperature
C. A person pushing a box across the floor
In this reaction, water acts as the base and donates a proton to hydrazine (H2NNH2). Hydrazine becomes protonated: [N2H5]<span>+ And thus hydrazine in this reaction is actually a base. The conjugate base of the acting acid H2O is OH- (hydroxide ion).</span>
