Answer:
The correct answer is option 1 "F(2-) "less than" C2(2+) "less than" O(2-) "less than" N(2-)".
Explanation:
Bond order is a term used in chemistry to identify the number of electrons involved in making the bonding between two or more atoms in a molecule. Bond order is equal to half the difference between the number of bonds in the atoms minus the number of antibonds. Therefore, the correct order of bond order from smallest to largest is as follows:
1. F(2-): equals to 0.5 (it has 8 bonds and 7 antibonds)
2. C2(2+): equals to 1 (it has 4 bonds and 2 antibonds)
3. O(2-): equals to 2 (it has 8 bonds and 4 antibonds)
4. N(2-): equals to 2.5 (it has 8 bonds and 3 antibonds)
Answer:
9 is the answer
Explanation:
because u need to divide 45 from 5 which is 9
Answer should be 1.5 M given that M is the SI unit for molarity!
Blood is considered a suspension because it contains particles that can settle out.
A (heterogeneous) suspension is defined as a mixture between a liquid and particles of a solid. In the case, the particles do not dissolve. The particles and the liquid are mixed up so that the particles are dispersed throughout the liquid. They are "suspended" in the liquid. A key characteristic of a suspension is that the solid particles will settle and separate over time if left alone.
This is exactly what happens when anti-coagulated blood is left to stand alone for some time. Blood cells separate and settle from the plasma, the watery part of the blood.
Yo sup??
Heat produced per gram of reactant=13.1 KJ
.=13100 J
Actual heart produced=1850 J
By applying unitary method we get the weight of reactant to be x
x=1850/13100
=0.141 gm
Hope this helps
