Answer:
Cobaltous Nitride,I think so anyway.......
Answer:
A. 3.7 x 10⁻³
Explanation:
In the beginning of the reaction there are 0.200 moles of reactant. After 25 minutes, remain 0.108 moles. That means the moles that wer descomposed are:
0.200 moles - 0.108 moles = 0.092 moles of reactant were descomposed.
That descomposition occurs in 25 minutes. The average rate of descomposition in moles / minute are:
0.092 moles Methyl isonitrile / 25 minutes = 3.7x10⁻³ mol/min.
Right option is:
<h3>A. 3.7 x 10⁻³</h3>
Most organic compounds are made of just 4 elements, which are carbon, hydrogen, oxygen, and nitrogen. (I think, I am not sure)
Hope that helps!!!
Its called ionic bonding! :^)
<span>Moles of aluminum carbonate = Mass / Molar mass
= 47.6 g / 233.99 g molâ’1
=0.203 mol
To find moles of oxygen:
In each mole of the carbonate there are 9 moles of oxygen
And thus there are 9 Ă— 0.203 moles of oxygen in the given quantity.
= 1.83 moles of oxygen
Within one mole of oxygen, we have 6.022 x 10^23 atoms
Amount of atoms within 1.827 moles of oxygen = 1.83 x 6.022 x 10^23
= 1.10 x 10^24 atoms</span>
