Answer:
for example the same boat and a lot more to the right thing in this country is a good thing to say about it is not a fan game that I have a lot more than the
HCl + NaHCO3 = NaCl + H2O + CO2
We have 0.033*0.2 = 0.0066 mol of Hcl
According to reaction we need the same amount of NaHCO3
M(NaHCO3) = 23+1+12+48=84g/mold
m = 0.0066mol * 84g/mol = 0.5544g
Answer:
Because the most reactive elements are<em> HALOGENS</em>.
Answer: Thus X is Plutonium
Explanation:
Alpha Decay: In this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. The mass number is reduced by 4 units and atomic number is reduced by 2 units.
General representation of alpha decay :

where Z = atomic number
A= mass number
X and Y = atomic symbol of elements

Thus 
Thus X is Plutonium with atomic number 94 and mass number 239
I would say they design and build things.
