A,D,and E I hope this helps
Ba(OH)₂ + 2HCl = BaCl₂ + 2H₂O
n(HCl)=c(HCl)v(HCl)
n{Ba(OH)₂)}=c{Ba(OH)₂}v{Ba(OH)₂}=2n(HCl)=2c(HCl)v(HCl)
v{Ba(OH)₂}=2c(HCl)v(HCl)/c{Ba(OH)₂}
v{Ba(OH)₂}=2*0.250*0.020/0.100=0.100 L = 100 mL

Answer:</h3>
1.265 g/mL
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of a rock as 43 g
- Volume of the rock as 34 mL
- Altitude of the rock as 4390 ft
We are required to calculate the density of the rock.
Density is the mass of an object per unit volume.
It is calculated by;
Density = Mass / volume
Therefore;
Density = 43 g ÷ 34 mL
= 1.265 g/mL
Thus, the density of the rock is 1.265 g/mL
