Two elements that have similar properties to copper are silver and gold, which are in the same group as copper (Group 11) on the Periodic Table. Copper, silver, and gold are the best electrical and thermal conductors of all the metals.
Answer:
Solution given:
1 mole of KCl
22.4l
1 mole of KCl
74.55g
we have
0.14 mole of KCl
74.55*0.14=10.347g
74.55g of KCl
22.4l
10.347 g of KCl
22.4/74.55*10.347=3.11litre
volume of each solution contains 0.14 mol of KCl contain 3.11litre.
Answer:
<h3>The answer is 1.04 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of coke = 21.36 g
volume = 20.5 mL
So we have

We have the final answer as
<h3>1.04 g/mL</h3>
Hope this helps you
Answer: It has a charge of -2 because it has 2 more electrons than protons meaning it has a negative charge of 2 which is -2. Neutrons don't effect charge.
( +1 +1 -1 -1 -1 -1) = -2
Each proton has a charge of +1 and each electron has -1.
2(1) - 4(1) = -2
