Answer:

In a chemical reaction, arrows separate reactants from products and points to where the reaction is going. On the other hand, the coefficients detail the amount of the components of the chemical reaction.

Explanation:

The way to represent a chemical reaction is through the chemical equation. To write this chemical equation, the following rules must be followed: The reactants are written on the left, and the products on the right, both, separated by an arrow that indicates the direction of the reaction.

The chemical equation must be balanced, leaving the same number of atoms of each of the elements. To balance a chemical reaction, numbers known as coefficients are placed in front of it, showing the relative number of atoms entering a reaction.

The arrows used by chemists means "react to produce" or "yield", such that when two substances react with each other they yield products, represented or shown by an arrow. The coefficients on the other hand, describe the lowest whole number ratio of the amounts of all of the reactants and products.

Which of the following chemical formulas show three molecules of a compound that has one
mr_godi [17]

The chemical formula : 3HgBr₂(Mercury(II) bromide)

<h3>Further explanation</h3>

Given

The chemical formulas of Mercury and Bromine

Required

The appropriate chemical formula

Solution

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

The number of molecules is determined by the coefficient in front of the compound

the number of atoms is determined by the subscript after the atom and the coefficient

Three molecules⇒ coefficient = 3

one atom of Mercury ⇒Hg

two atoms of Bromine ⇒ Br₂

The chemical formula : 3HgBr₂

How many milliliters of a 0.40%(w/v) solution of nalorphine must be injected to obtain a dose of 1.5 mg?
ozzi
The number  of Ml  of  a  0.40 %w/v solution  of   ,nalorphine  that must  be injected  to  obtain  a  dose  of 1.5 mg is  calculated as  below


since M/v%   is  mass  of solute  in  grams per 100  ml

convert Mg to  g
1 g = 1000 mg  what  about  1.5 mg =?  grams
=   1.5 /1000 = 0.0015 grams


volume is therefore =  100 (  mass/ M/v%)

= 100  x(  0.0015/ 0.4) =  0.375  ML
