For each of the following unbalanced equations,
calculate how many milligrams of each product
would be produced by complete reaction of
10.0 mg of the reactant indicated in boldface.
Indicate clearly the mole ratio used for the
conversion.
a. FeSO4(aq) + K2CO3(aq) →
FeCO3(s) + K2SO4(aq)
b. Cr(s) + SnCl4() → CrCl3(s) + Sn(s)
C. Fe(s) + Sg() ► Fe, Sz(s)
d. Ag(s) + HNO3(aq) →
AgNO3(aq) + H2O(l) + NO(g)

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
