A. Strong & Weak nuclear forces which are attractive. And electromagnetic.
b. Because the more electronegative atom really wants to complete it's valence shell, so it either covalently, or non-covalently bonds to the other atom.
c. Ummm, ask google? Well, it's kind of logical as well, but the part that Coulomb's law plays into it - I do not know.
C the immigration rate is higher than the emigration rate
Yes, people should be concerned because plaque buildup might cause your breath to smell bad, or cause your teeth to look very yellow, consider brushing your teeth and using mouth wash daily and don’t drink or eat unhealthy foods that will cause your teeth to look bad. plaque buildup might also cause damage to the stomach and maybe affect when you have to use the restroom.
Answer:
Molar solubility of AgBr = 51.33 × 10⁻¹³
Explanation:
Given:
Amount of NaBr = 0.150 M
Ksp (AgBr) = 7.7 × 10⁻¹³
Find:
Molar solubility of AgBr
Computation:
Molar solubility of AgBr = Ksp (AgBr) / Amount of NaBr
Molar solubility of AgBr = 7.7 × 10⁻¹³ / 0.150
Molar solubility of AgBr = 51.33 × 10⁻¹³
Answer:
The solution to the question is as follows
(a) The rate of ammonia formation = 0.061 M/s
(b) the rate of N₂ consumption = 0.0303 M/s
Explanation:
(a) To solve the question we note that the reaction consists of one mole of N₂ combining with three moles of H₂ to form 2 moles of NH₃
N₂(g) + 3H₂(g) → 2NH₃(g)
The rate of reaction of molecular hydrogen = 0.091 M/s, hence we have
3 moles of H₂ reacts to form 2 moles of NH₃, therefore
0.091 M of H₂ will react to form 2/3 × 0.091 M or 0.061 M of NH₃
Hence the rate of ammonia formation is 0.061 M/s
(b) From the reaction equation we have 3 moles of H₂ and one mole of N₂ being consumed at the same time hence
0.091 M of H₂ is consumed simultaneously with 1/3 × 0.091 M or 0.0303 M of N₂
Therefore the rate of consumption of N₂ = 0.0303 M/s
