The term absolute zero is given because the volume and the temperature comes to 0. So according to Charles law,
<span>At const K temp, </span><span>Volume is proportional to Temperature. </span>So the volume is also 0. <span>P = nRT/V. </span><span>T=0 and P=0</span>
It has 49 electrons as well. The amount of protons and electrons are equal.
Answer:
19.28 g/cm^3 to the nearest hundredth.
Explanation:
The volume of water displaced = the volume of the metal.
density = mass / volume
0.0694 kg = 0.0694 * 1000
= 69.4 g.
Density = 69.4 / 3.6
= 19.28 g/cm^3.
Calcium chloride.
It might seem reasonable to call it calcium dichloride, but the IUPAC name for it is calcium chloride.
Answer:
2-; anion
Explanation:
1. Charge
Charge = +8 - 10 = -2
However, when we talk about the charge on an ion, we put the number first, so we say charge is 2-.
2. Type of ion
The ion has a negative charge, so it is an anion.
The nucleus has eight protons (oxygen), so it is an oxyanion.
The symbol for an oxyanion with two negative charges is O²⁻, and its name is the oxide ion.
