The answer
the general equation of the reaction is
<span>NH4NO3 -------------- N2O + 2H2O
</span><span>The molar mass of NH4NO3 is 80.03
</span>The mass of NH4NO3 is <span>160.1 g
so we can deduce that
n</span>NH4NO3 = number of mole of NH4NO3 = 160.1 g / 80.03 =2 moles
by using proportion property
NH4NO3 -------------- N2O + 2H2O
1mole 1mole 2 moles
nNH4NO3 nH2O
the number of mole nH2O can be found by
1/ nNH4NO3 = 2 / nH2O
nH2O = 2 x nNH4NO3 = 2 x 2 = 4 moles
to find the mass, we use
mH2O = 4 moles x 18.01 g /mol = 36 g
Answer:
The answer is B
Explanation:She is collecting data about how the growth will be affected
Answer:
Chernobyl Accident 1986. The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel. The resulting steam explosion and fires released at least 5% of the radioactive reactor core into the atmosphere and downwind – some 5200 PBq (I-131 eq).
Explanation:
The concentration of A will be <em>0.34 mol·L⁻¹</em> after 60 min.
In a first-order reaction, the formula for the amount remaining after <em>n</em> half-lives is
If
