Answer:
Weight reduces
Explanation:
As you continue to move away form the earth to the moon, weight begins to reduce because the acceleration due to gravity reduces.
Weight is the force gravity on a body;
Weight = mass x gravity
Since mass is consistent and does not vary, the weight changes due to differences in gravity on the bodies.
- On the moon, the gravity is lower than on the earth.
- This also, makes the weight lower on the moon.
Each mole of a substance contains 6.02 x 10²³ particles
Atoms of Fe = 4.5 x 6.02 x 10²³
= 2.709 x 10²⁹ atoms
23.9 11.00 would be the wrong answer because I guessed
Electron affinity is a measure of the tendency of a neutral atom to gain electrons and form a negative ion. It can be represented by a general equation:
X + e- → X-
The value of electron affinity decreases on moving down a group. This is because on moving down a group the atomic size increases as a result the added electron feels less pull or attraction towards the nucleus.
In group 14, Carbon 'C' is the first member and therefore will have the highest electron affinity.
Ans : A) Carbon
