The general form of a compound can be written in the form
of:
[X(a) Y(b)] ^ c
Where a and b are subscripts, and c is the superscript of
the whole formula.
The relationship that we can derived here between the
constants is:
(valence of X) * a + (valence of Y) * b = c
Since the formula obviously has no superscript, therefore
c = 0. We also know in chemistry class that the valence of Cl is -1, therefore:
valence of X * 1 + (-1) * 3 = 0
valence of X - 3 = 0
<span>valence of X = 3</span>
Answer:
1 makes the most sense
Explanation:
There is no way blood pressure will be decreased especially if your ventricles are erratically contracting for a long period of time. So 3 and 4 are out. And you said number 2 is wrong so my finally answer is 1.
Answer:
Explanation:
Chemical Equations are representations of chemical reactions in terms of the symbols and formulae of the elements and compounds involved. A chemical equation usually have the reactant at the left hand side while the product is on the right hand side.
A chemical Equation is of little or no value if is not in balanced equation. When an equation is balanced , the total number of atoms of any element on the left-hand side of it must be equal to the total number of atoms of that element on the right hand side.
in the given question; we are given a word problem of chemical symbol to compute and also to balance the chemical equation.
From below; the chemical equation can be written as:
From the above equation we will notice that it is not truly balanced ; so th balanced equation can be written as:
Answer:
It cannot conduct electricity, however adding salt or sugar will make the water have impurities/other substance making it easier to conduct electricity
Explanation:
Distilled water by itself does not contain impurities, thus, it cannot <em>conduct </em>electricity.
When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely, increasing the conductivity.

Answer:
d. decomposition
Explanation:
decomposition reaction is a reaction in which a compound breaks down into 2 or more substances.
the general form is: AB → A + B
