The empirical formula of the following compounds 0.903 g of phosphorus combined with 6.99 g of bromine.
<h3>What is empirical formula?</h3>
The simplest whole number ratio of atoms in a compound is the empirical formula of a chemical compound in chemistry. Sulfur monoxide's empirical formula, SO, and disulfur dioxide's empirical formula, S2O2, are two straightforward examples of this idea. As a result, both the sulfur and oxygen compounds sulfur monoxide and disulfur dioxide have the same empirical formula.
<h3>
How to find the empirical formula?</h3>
Convert the given masses of phosphorus and bromine into moles by multiplying the reciprocal of their molar masses. The molar masses of phosphorus and bromine are 30.97 and 79.90 g/mol, respectively.
Moles phosphorus = 0.903 g phosphorus 
= 0.0293 mol
Moles bromine 6.99 g bromine
=0.0875 mol
The preliminary formula for compound is P0.0293Bro.0875. Divide all the subscripts by the subscript with the smallest value which is 0.0293. The empirical formula is P1.00Br2.99 ≈ P₁Br3 or PBr3

Lithium is an element that has an electronic configuration of 2,1. So when forming bonds, it tries to release one of its electrons in the last shell to reach the octet state. Normally when atoms release electrons they get positive charge since the number of protons which bear positive charge, is higher than number of electrons which bear negative charge. So when reaching its octet state, lithium gains positive charge!
Hope this helps! Tbh am not good at explaining. If u have any doubts, ask me!

2,000,000/25=80,000
The answer is 80,000 polio viruses
Answer:
0.0140 M H₂C₆H₆O₆.
Explanation:
- We should mention the relation: <em>Ka = α²C,</em>
Where, Ka is the dissociation constant of the acid.
α is the degree of ionization of the acid.
C is the concentration if the acid.
<em>The percent of ionization (α %) = α x 100.</em>
α = √Ka/C
∴ α is inversely proportional to the concentration of the acid.
<em>So, the acid with the lowest concentration has the greatest percent ionization.</em>
Answer:
definitely yes
Explanation:
because the hydrogen and oxygen will combine and make water
