Answer:
The mass of an average copper atom is
Explanation:
Given:
The total mass of copper atoms,
Number of atoms,
Now, we are asked to find the mass of 1 copper atom.
We use unitary method to find the mass of 1 copper atom.
Mass of atoms = m
∴ Mass of 1 atom =
Plug in 63.5 for 'm', for 'N' and simply.
Mass of 1 atom =
Therefore, the mass of an average copper atom is
You can start by writing out the molecular formula of each molecule.
Aluminum (Al 3+) Phosphate (PO4 3-)
AlPO4
Nickel II (Ni 2+) sulfide (S 2-)
NiS
Aluminum Sulfide
Al2S3
Nickel Phosphate
Ni3(PO4)2
If you’re wondering, we get those charges by looking at the periodic table. The metals usually have a + charge based on their group number. The nonmetals usually - charge egual to 8 - their group number.
You then balance the ions by flipping the charges, dropping the signs, and adding them in as subscripts.
Now we can put it into an equation
AlPO4 + NiS —-> Al2S3 + Ni3(PO4)2
Balance by adding coefficients
2 AlPO4 + 3 NiS —-> Al2S3 + Ni3(PO4)2
Waterways or lakes. at least that’s what google said lol.
Answer:
I'd say the answer is B) Load.
Hope this helps. :-)

The international scientific units of measurements
<h3>
Explanation:</h3>
- SI units are units of measurement that are accepted and agreed upon globally as standard units of measurements.
- Examples include, meters(m) to measure length, kilograms(kg) to measure mass and seconds(s) to measure time among others.
- SI units can however, be converted to other units using multiplication factors. For example to convert kg to g we multiply the number of kg with 1000.
