pH(D) A compound that increases the hydroxide ions (OH-) when it is dissolved in a solution
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
There is a lot of water on earth. If oxygen was very soluble in water, the oceans would absorb and hold the oxygen of the atmosphere and there would be none left for plants and animals.
Hope this help you!!
