The formula for potassium hydrogen carbonate is CHKO3 .
Answer:
Freezing does not affect the mass of Juice because mass is constant and only the volume increases.
Explanation:
Freezing does not affect the mass of liquid and only volume increases, because when liquid freezes, the molecules stick together in hexagonal form and then expand, the mass remain constant and it's volume increases when it is frozen and become solid which signify that when there is increase volume, frozen juice is less dense than liquid juice.
Carbon dioxide acts as a blanket or a glass shield
The chemical equation is
Cu(s) +4HNO3(aq) ⇒ Cu(NO3)2(aq) + 2NO2(g) + 2H2O(g)
Answer:
12
Explanation:
In the right hand side of the equation, there are three compound which contains O2, which are;
Cu(NO3)2 , number of oxygen atoms =3*2 =6
2NO2, number of oxygen atoms = 2*2=4
2H2O, number of oxygen atoms =2*1=2
Total number of oxygen atoms on the right side of equation = 6+4+2 =12
