Yes it is true. When entering a number as a criterion you type the number without any dollar signs or commas. :)

The sum of oxidation numbers in a neutral compound is always zero. (Note that in order for this to be true, the oxidation number of each type of atom present must by multiplied by the number of such atoms present in the formula unit for the compound before the addition is performed.)

True. Organisms must compete with each other for space to live

No.Water is a binary compound. A binary compound contains two elements, regardless of the number of atoms of each.

The lines do not not touch each other.

We can say that this is true to some extent. We must all agree that the properties of a compound DOES depend on the elements it contains since a variation in the elements changes the properties of the compound. However, what we must remember is that the properties of the compound does NOT depend on the properties of the elements that make up the compound. A simple example is water, made of hydrogen and oxygen…

The measurements must be equal to each other.

The measurements must be equal to each other.

In a nonlinear equation, each variable must only have one solution.

It must be proven to be true by several different individuals not known to each other.
