Answer: Water is the solvent in this recipe.
Explanation: A solvent is " a molecule that has the ability to dissolve other molecules". Lemon juice and sugar are solutes.
Which of the following is a neutralization reaction?
a
SiCl4 + 4 H2O → H4SiO4 + 4 HC
b
HCl + NaOH → NaCl + H2O
c
6 CO2 + 6 H2O → C6H12O6 + 6 O2
d
2Al + 6HCl → 2AlCl3 + 3H2
Answer:
B
Explanation:

How many moles of copper are needed to react with sulfur to produce 0.25 moles of copper (i) sulfide according to the following reaction: 2 Cu + S = Cu2S
Answer:
0.5 mole
Explanation:
The equation for the reaction is given below:
2Cu + S —> Cu2S
We can calculate the mole of copper (Cu) needed to react with sulphur (S) to produce 0.25 mole of copper(I) sulfide (Cu2S) by doing the following:
From the balanced equation above,
2 moles of Cu reacted to produced 1 mole of Cu2S.
Therefore, Xmol of Cu will react to produce 0.25 mole of Cu2S i.e
Xmol of Cu = 2 x 0.25 = 0.5 mole
Therefore, 0.5 mole of copper (Cu) will react with sulphur (S) to produce 0.25 mole of copper(i)sulfide (Cu2S)
