Identify the products in the following chemical reaction: Multiply chose 2NaHCO3 + CaCl2 → CaCO3 + CO2 + 2NaCl + H2O

B. CaCl2

C. CaCO3

D. CO2

E. NaCl

H2O

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
