To balance it, it would be N2 + 3H2 ------> 2NH3.
for c) it would be 2N2 + 6H2 -------> 4NH3
Explanation:
the correct match can as follows:
1. helium ⇒ discrete atoms (helium is an inert gas)
2. oxygen ⇒ molecules (oxygen exists in molecular form as O2)
3 Magnesium ⇒ matalic lattice ( Magnesium is a metal FCC crystal Structure :) )
4 Aluminum⇒ covalent network (since it is situated in the middle of the group and posses amphoteric properties too)
I attached the working and the answer to the question below.
Please note that C = speed of light, ν = frequency, λ= wavelength
<span> The wavelength of a 2.80 Hz wave is
1.07 </span>
× 10¹⁰
Expected to deal with what? Fires?
Answer:
True
Explanation:
Molecular mass of
:
Molecular mass of Ca + molevular mass of C + molecular mass of O × 3
40g + 12g + 16 × 3g
= 40g + 60 = 100g
Thus its true
