Answer:
Explanation:
The theory of propagation of error in case of addition and subtraction states that maximum errors are added in absolute terms in both the operation of addition and subtraction . So in this case the subtracted value will be
10.5775 - 10.3005
= .2770 g
errors will be added ie in subtracted value we can find error to the tune of
.0002 + .0002 = .0004 g
So the subtracted value will be written as
.2770 ± .0004
Element’s oxidation number decrease that because that element has received electrons from another element
Explanation:
A reduction in oxidation state is known as a reduction. Such reactions include the formal removal of electrons: a net gain in electrons moving a reduction, and a clear loss of electrons being an oxidation.
An oxidation-reduction (redox) reaction is a type of synthetic reaction that involves a transfer of particles between two species. An oxidation-reduction reaction is any synthetic reaction in which the oxidation number of a molecule, atom, or ion quarters by winning or missing an electron.
Question:
Diffusion is the movement of particles from high to low concentration. True or False
Answer:
True.
Explanation:
Diffusion is a process that allows the movement of substance or particles in and out of cells through a semipermeable membrane.
Diffusion is a process that allows the spread or movement of particles from the region of higher concentration to a region of lower concentration through a semipermeable membrane.
Diffusion only occurs in gases and solution but not in solids, it also occurs only where particles can move freely.
Note: When particles move from the region of higher concentration to a lower concentration, it gives room for even, uniform and random distribution of particles.

I think it's C - sorry if I'm wrong
