Answer:
False
Explanation:
If the row echelon form of the augmented matrix for a linear system has a row of zeros, then the there must not have infinitely many solution,
we can prove this with an example. Suppose we have an augmented matrix A for linear system with a row of zeros,
1 0 0 1
A= 0 1 0 -2
0 0 1 - 1
0 0 0 0
we get
x1=1
x2=-2
x3=-1
so, system has an unique solution.
we can take inference that the given statement is wrong
Answer:
Potassium was the first metal to be isolated by electrolysis. It was discovered by the English chemist Sir Humphry Davy by decomposing molten potassium hydroxide (KOH) with a voltaic battery.

Hope this helped :) good luck! ❤️
Explanation:
A <em>coolant solution</em> is a <u><em>homogeneous </em></u>mixture because the coolant particles are not chemically combined with the water (keep their properties) and they are evenly distributed throughout the water.
The overall charge of an atom is positive if the number of electrons is less than the number of protons. Electrons are negatively charged particles while protons are positively charged particles. If there are less electrons as compared to the number of protons in an atom, then naturally the overall charge of the atom would be positive since there are excess protons. Another case would be that the overall charge of an atom is negative if the number of electrons is greater than the number of protons. An atom having more electrons than the number of the protons present would lead to a negative value of the charge since there are excess electrons.
