Answer:
Explanation:
Given the following mathematical expression;
A = ½(a + b)h
To make a the subject of formula (express a in terms of A, b and h);
First of all, we would cross-multiply;
2A = (a + b)h
Opening the bracket, we have;
2A = ah + bh
Rearranging the mathematical expression, we have;
ah = 2A - bh
Answer:
Explanation:
The expected product is MgO, so the 1-to-1 mole ratio Mg to O in the product is all that is required.
Bynari means that the compound is formed by two kind of elements.
You have listed three ions, V 5+, Cl - and O 2-.
Binary ionic compounds are formed by a positive ion and a negative ion, so the possible ionic compound formed by the listed ions are:
1) VCl5, where the number 5 next to Cl is a subscript.
2) V2O5, where the number 2 next to V and the number 5 next to O are subscripts.
Subscripts are used to indicate the number of atoms of each element in the formula.
So, the empirical formula searched are VCl5 and V2O5.
I can give you other examples with more ions.
Ca (2+) and S(2-) => Ca2S2 => CaS
Na(+) and F(-) => NaF
Cs(+) and Br(-) => CsBr

Answer:</h3>
4.3 miles
<h3>
Explanation:</h3>
We are given;
Distance of 22,704 feet
We are required to determine the number of miles in 22,704 feet
- To convert one unit to another we use conversion factors
- Therefore, we need to know the suitable conversion factor.
- That is, 1 mile/5,280 feet
- Thus, to determine the number of miles we multiply the number of feet with the conversion factor.
That is;
= 22,704 feet × 1 mile/5,280 feet
= 4.3 miles
Therefore, there are 4.3 miles in 22,704 feet
