Answer:
Zn + 2HCl → ZnCl2 + H2
Explanation:
Zn + HCl → ZnCl2 +
The complete equation is given below:
Zn+ HCl → ZnCl2 + H2
Now we can balance the equation by doing the following:
There are 2 atoms of Cl and 2 atoms of H on the left. This can be balanced by putting 2 in front of HCl as shown below:
Zn + 2HCl → ZnCl2 + H2
Answer:
yes, because evidence from scientifically research studies, is important because it lets us make decisions based on what works with studies of science we can know if this is right or not

Explanation:
Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions.
Answer:
Mass of copper oxide: 10g
Mass of copper: 8.882g
Mass of oxygen: 1.118g
<u> Cu</u> <u>O</u>
8.882 1.118
Divide by 
8.882÷63.5 1.118÷16
0.14 0.07
Divide by the lowest number 0.14/0.07 0.07/0.07
2 1
Check the ratio now, Cu has 2 atoms and O has 1 atom .
The formula is
