Answer:
In 3K2O3 - 6 K atoms, 9 O atoms
In 2H3NCH3Br - 12 H atoms, 2 N atoms, 2 C atoms, 2 Br atoms
In 4 Ar2CO3 - 8 Ar atoms, 4 C atoms, 12 O atoms
Explanation:
All you need to do is multiply the coefficient by the number of each atom in the compound. For example, H3NCH3Br has 1 nitrogen, 1 carbon, 1 bromine, and 6 hydrogens. If you have 2H3NCH3Br, just multiply all those numbers by 2.
Answer:
762.60 g
Explanation:
In order to convert from moles of a substance into grams, we need to multiply the number of moles by the substance's molar mass:
- Moles * Molar Mass = Grams
With the above information in mind, we can <em>use the data given by the problem</em> and <u>calculate how many grams are there in 12 moles of Cu</u>:
- 12 mol * 63.55 g/mol = 762.60 g
2 Fluorine atoms covalently bonded with each other, each sharing an equal number of a single, one valence electron to achieve a stable octet, would form a diatonic fluorine gas. It is a diatomic molecule, a molecule consisting of 2 atoms that are the same, in this case fluorine.
Answer:
A scientific claim is a statement about the results of your experiment that is supported by evidence gathered during the experiment and reasoning that explains how the evidence is connected to the claim. For example: Claim: Air is matter.
