Hey there!
Zn + HCl → ZnCl₂ + H₂
First, balance Cl.
1 on the left, 2 on the right. Add a coefficient of 2 in front of HCl.
Zn + 2HCl → ZnCl₂ + H₂
Next, balance H.
2 on the left, 2 on the right. Already balanced.
Lastly, balance Zn.
1 on the left, 1 on the right. Already balanced.
Our final balanced equation:
Zn + 2HCl → ZnCl₂ + H₂
Hope this helps!
Balloons filled with oxygen will sink and balloons filled with nitrogen will also sink, this is because oxygen is more dense than air but nitrogen is only slightly less dense than air meaning it is not enough for the nitrogen to rise

Answer:
1) represented by a lower case letter
2) always masked by dominant genes
3) only expressed in the absence of a dominant gene
Explanation:
So if I take a black and a yellow marker- and tried drawing the yellow over the black- or the other way around- you'd still only see the black marker. The recessive trait is like the yellow marker. Now if I drew the yellow marker with another yellow marker you would see the yellow. I hope this helps!
