mass h
<h3>

</h3>
Explanation:
molar mass is equal to number of mass over moles we take 14.19 over17 molar mass of ammammonium equals 0.8347 incase of moles. 1H=1Nh3 ,so. n.H=0.8347 Mr=2 ,M.H=? Mr=m/n. 0.8347x2=1.669grams
Answer:
f = 0.084 s⁻¹
Explanation:
Given data:
Frequency of light = ?
Wavelength = 35.6 m
Solution:
Formula:
Speed of light = wavelength × frequency
Speed of light = 3× 10⁸ m/s
by putting values,
3× 10⁸ m/s = 35.6 m × f
f = 3× 10⁸ m/s / 35.6 m
f = 0.084 s⁻¹
An anion is a negatively charged particle.
Answer:
The percent yield is 66.7%
Explanation:
1. The balanced chemical reaction to obtain carbon dioxide from the methane is:

2. Calculathe the theoretical quantity of carbon dioxide.
As the problem says that the limiting reagent is the methane, all the calculations will be made from this quantity:

3. Calculate the percent yield:
Percent yield = 
Percent yield = 
Percent yield = 66.7%
