Answer:
no of neutron = atomic mass - atomic number
Explanation:
here
atomic mass = 64
atomic number = 30
no of neutron = <span>64−30</span>
no of neutron = 34
Answer:
K = 4.07x10⁻³
Explanation:
Based on the reaction:
NH₄I(s) ⇄ NH₃(g) + HI(g)
You can define K of equilibrium as the ratio of concentrations of reactants and products, thus:
K = [NH₃] [HI] / [NH₄I]
But, as NH₄I is a solid, is not taken into account in the equilibrium, that means K expression is:
K = [NH₃] [HI]
As the concentrations in equilibrium of the gases is:
[NH₃] = 4.34x10⁻²M
[HI] = 9.39x10⁻²M
Equilibrium constant, K, is:
K = 4.34x10⁻²M * 9.39x10⁻²M
<h3>K = 4.07x10⁻³</h3>
During a combustion reaction the carbon in a hydrocarbon compound is paired with Oxygen (O2) in the air to form Carbon-Dioxide (CO2), whilst the Hydrogen too pairs with Oxygen to form water vapour (H2O). Heat is also produced during this reaction.
Condensation happens<span> when the temperature of air containing moisture decreases. falling air temperatures cause condensation because warm air can hold more moisture than </span>cold<span> air. when warm air in the </span>bathroom<span> is heated by the shower to temperatures as much as 100 degrees F, the air becomes saturated with moisture, hope it helps</span>
