How many grams of ammonia are produced from 6 moles of nitrogen?
Answers
Answer: The equation is 3H2 + N2 → 2NH3
If 6 moles of H2 gas react with N2 (assuming all reactants react)
6 * 2/3 moles of ammonia must be produced.
Therefore 4 moles of ammonia can be produced.
Since it is a gaseous equation (all reactants/products are gases), we can just assume that the Mr of the gases do not affect the amounts of the reactants or the products.

What is true about Carbon-14 and Carbon-12?
a. The mass of the Carbon-14 sample is less than the Carbon-12 sample, but the reactivity of both samples was the same.
b. The mass of the Carbon-14 sample is greater than the Carbon-12 sample, but the reactivity of both samples was the same .
c. The reactivity of the Carbon-14 sample is less than the Carbon-12 sample, but the mass of both samples was the same.
d. The reactivity of the Carbon-14 sample is greater than the Carbon-12 sample, but the mass of both samples was the same.
Answers
Answer:
B.
Explanation:
Correct: b. The mass of the Carbon-14 sample is greater than the Carbon-12 sample, but the reactivity of both samples was the same .
- C-14 has two additional neutrons, so is heavier than C-12. The chemical properties will be the same, however.
Lead has an atomic number of 82. Which statement describes all neutral atoms and ions of lead?
Neutral atoms of lead must have 82 electrons. Ions must have 82 electrons, as well.
Neutral atoms of lead must have 82 neutrons, but ions can have more or fewer.
Neutral atoms of lead must have 82 protons. Ions must have 82 protons, as well.
Neutral atoms of lead must have 82 protons, but ions can have more or fewer.
Answers
The neutral atom of lead must have 82 protons while ions can have b or less than 82.
The atomic number of an element is the number of protons in the nucleus of the element.
Also, for neutral atoms, the number of protons equals the number of electrons.
In ionic form, the number of protons/electrons of an atom may vary and be different from that of the neutral form.
Positive charges mean that the ion has less proton than its neutral version while negative charges mean that it has more electrons than its neutral version.
Thus, the neutral atom of lead will contain an equal number of protons as the electrons while its ionic form can have more or less than 82 protons.

Circle the compound that has the higher boiling point and explain why we see the
differences we do
Answers
Answer:
1. Ethane has a higher boiling point
2. Heptyne has a higher boiling point
3. Octane has a higher boiling point
Explanation:
1. Ethane has stronger intermolecular attractions (van der Waal's forces) than ethene and so has the higher boiling point.
2. The longer (and the straighter) the chain, the greater the opportunity for intermolecular interactions, and thus the greater the boiling point. You should look up these boilig points! n-Pentane has a normal boiling point of approx. 36 ∘C ; n-heptane boils at 98 ∘C .
3. Octane has a high boiling point, because its molecule contains 8 Carbon atoms, and with increasing molecular weight of hydrocarbon its boiling temperature increases.

Neutralization reactionFrom the question, we are to determine what substance x is.
First, we will identify the gas given off.
The gas that turns lime water milky is carbon (IV) oxide (CO₂) gas.
RECALL: Acids react with carbonate to produce salt and water with the release of carbon dioxide gas.
Hence, substance x is an acid. The process that takes place in the reaction is a Neutralization reaction.

Please Help giving high points. Perform the following mathematical operation, and eport the answer to the correct number of significant figures. 4568/1.3 = [?]
Answers
Answer:
1.3 is the value with the lowest sig figs in your question. So we have 2 sig figs.
4568/1.3 = 3513.84615
Now let's change the answer in sig figs.
We know that trailing zeros don't actually count as part of sig figs.
So we can round the answer to 3500, having the 2 sig figs (3 and 5) while the trailing zeros don't count.
Final answer = 3500
