Answer:
Hello
12 grams
The mass of one mole of carbon-12 atoms is 12 grams.
Hope it helps You.....
Explanation:
Answer:
D
Explanation:
The amount of energy released or absorbed is equal the product of the mass, the specific heat capacity and the temperature change. The temperature change being the difference between the final and initial temperature.
Q = mc∆T
Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/g∙K)
∆ is a symbol meaning "the change in" ∆T = change in temperature (Kelvins, K)
From the data provided in the question, we can deduce that:
Q = 16.7KJ = 16,700J
m = 225g
c = 1.74J/g.k
For the temperature, let the final temperature be f. This means our ∆T = f - 20
16,700 = 225 * 1.74 * (f - 20)
16700 = 391.5 (f - 20)
f - 20 = 16700/391.5
f - 20 = 42.7
f = 20 + 42.7 = 62.7
Answer:
All atoms of isotopes of a particular element have the same number of protons, but different numbers of neutrons in their nuclei.- True
The reaction of tetrahedral intermediate and the two leaving groups, methoxide and amide anion favour product.
<h3>What is leaving group? </h3>
A leaving group is a group of atoms or an atom which is able to break away from a molecule as a stable species or with a lone pair, breaking the bond between the molecule and itself.
<h3>What is intermediate? </h3>
A stage is come before forming product. This stage is termed as transition stage and the reactant at this stage is termed as intermediate.
According to Le Châtelier's Principle, a reactions always tend towards the equilibrium, the reaction produces more products from the excess reactant, that's why it causing the system to shift to the left which allows the system to reach equilibrium.
Due to this reason, this reaction shift towards product.
Thus, we concluded that the reaction of tetrahedral intermediate and the two leaving groups, methoxide and amide anion favour product.
