avanturin [10]3 years ago
7 0

Answer:

4 ions

1  M³⁺ ion and 3 NO₃⁻ ions ( Where M³⁺ stands for the group 13 cation).

Explanation:

Group 13 elements are Boron , Aluminium, Galium, Indium and Thalium. When they form ionic compounds they can lose their  three valence electrons to form a tripositive (+3) ion. Nitrate ion is a negative ion with a single negative(-1) charge. When these two form a compound 3 univalent negative nitrate ions must combine with one tripositive group 13 element to form a neutral compound. So the total no of ions is 4.

padilas [110]

Answer:

The answer to your question is: C. The specific latent heat of fusion

Explanation:

A. The specific latent heat of vaporization  Specific latent heat of vaporization indicates the transition from liquid to vapor, but we are not looking for this definition. This answer is wrong.

B. The specific heat indicates the amount of heat needed to increase the temperature of water 1°C, so this answer is wrong.

C. The specific latent heat of fusion . This heat indicate the transition from solid ie to liquid, so this is the right answer.

D. The internal energy measures the energy of the molecules of a substance, so this answer is wrong.

Please answer both questions.
Deffense [45]

Answer:

1)Krypton

2)11H

Explanation:

electrons=protons

protons=atomic number

mass number=protons+neutrons

mass number is the superscript

atomic number is the subscript.

1)The answer is Krypton because its atomic number= number of protons=number of electrons is 36.

mass number is 46+36=82.

2)subscript=atomic number=number of protons=number of electrons

i. H = electrons=1

=neutrons=0

ii. Cl=electrons=17

=neutrons=35-17=18

iii. Na=electrons=11

=neutrons=23-11= 12

so the answer is Hydrogen because it has 1 electron and 0 neutron.

I hope this helps.
