<span>Atomic number and mass number for the carbon isotope with seven neutrons are:
Z,A = 6,13
There are 3 isotopes of carbon that are carbon 12, carbon 13 and carbon 14.
The carbon atom with seven neutron is carbon 13. Each carbon has 6 protons so its atomic number is 6 and when it has seven neutron then mass number will be (6 + 7) = 13
So, atomic number Z is 6 and mass number A is 13.</span>
<span>The relationship between the amount of space between particles and the state of matter is that if the distance between the particles is very very less or closely packed) then it said to be a solid , If the distance between the particles is very less (more than that of solid) then the matter is a liquid & If the distance between the particles is less (more than that of liquid) then it is said to be gaseous. By this we conclude that when the amount of space between the particles varies then the states of matter (Solid , Liquid , Gas) also differs.</span>
Answer:
as temperature increases, solubility of gas decrease
1)general or nonspecific observation- Qaulitative
2)educated guess- hypothesis
4)measured observation- quantitative
5)standard reference data or experiment-control
6)a presently accepted explanation of how something happens-law
8) a curve drawn to average delvations- best fit curve
Answer:
Pure covalent
Explanation:
To know the type of bond between two atoms you must find the electronegativity difference of them:
If electronegativity difference is:
< 0.4: Pure covalent.
Between 0.4 and 1.8: Polar covalent.
> 1.8: Ionic.
The electronegativity of Zn is 1.65 and Ni is 1.91. Electronegativity difference is:
1.91 - 1.65 = 0.26
That means the type of bond is:
<h3>Pure covalent</h3>
