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:
b.fission, because the reaction absorbed energy
Explanation:
Answer:
the mechanical advantage is 50 because 0.50/0.01=50
The increasing order of photons in terms of energy is Er < Ey < Eb
A photon is a tiny particle of electromagnetic radiation and its energy is proportional to the frequency and rest mass as zero.
By using the formula:
E = h * ν
E = h * c / λ
h = planks constant
c = speed of light
Since h * c is constant
E is inversely proportional to wavelength λ
For blue:
λ = 453 nm
Eb= k / 453
where k is constant
For red:
λ = 660 nm
Er = k / 660
For yellow:
λ = 595 nm
Ey = k / 595
Therefore,
The increasing order of photons in terms of energy is
Er < Ey < Eb.
