(exact weight of isotope #1) (abundance of isotope #1) + (exact weight of isotope #2) (abundance of isotope #2) = average atomic weight of the element(68.72*61.29) + (39.71*70.92) = 4211.84 + 2816.237028.07/100= 70.28
70.28 is the atomic mass of Gallium for the location
Answer:
A neutralization reaction between an acid and a metal hydroxide produces salt and water.
Explanation:
In a neutralization reaction, an acid and a base are combined according to the following example (hydrochloric acid and sodium hydroxide):
HCl + NaOH ---> H20 + NaCl
They are generated as products: water and a salt, in this case sodium chloride.
The first answer choice would be more conservative to our environment
