Answer:
A. True
Explanation:
The octane number is determined by comparing the characteristics of gasoline to isooctane (2,2,4-trimethylpentane) and heptane. The correct option is option A.
Basically, the higher the octane number, the greater the resistance of the gasoline to knocking.
As there was no electric charge on neutrons, and they did not get affected by electromagnetic fields.
Explanation:
The functions of the neutron in atoms is:
To hold the nuclei with coulombic repulsion between the protons.
The neutron has no charge on it and hence were not discovered.
Its mass is slightly less than the proton.
It provides stability to the atom.
Lord Chadwick is credited to prove the existence and discovery of neutron.
He proved that the nucleus of the atom has its mass in the centre as neutron+ proton.
He bombarded beryllium with alpha particles, and found high energy radiation.
Answer:
Option C.
The Bohr effect describes the effect of pH on the affinity of hemoglobin for oxygen.
Explanation:
The hemoglobin is the oxygen carrying part of the blood. However, According to Christian Bohr, the binding affinity for oxygen by the hemoglobin in the blood is greatly affected by the acidity and content of carbon dioxide in the blood. As a matter of fact, they are inversely related. The more acidic the blood is, or the lower the pH of the blood, the lower the amount of oxygen that can become bonded with the hemoglobin in the blood.
They all have a certain amount of protons electrons and neutrons.
Answer:
I think it's because it shows properties that are similar to noble gases.
