one molecule of bromine and two molecules of potassium chloride combine in a reaction. How many atoms are in the products?
2
3
4
6
I think its 2 because it says products not product
maybe a bit of a trick question ...
"atoms" are conserved in chemical reactions
the three molecules in the reactants contain six atoms total
those same six atoms end up in the products
is this right??
Six
Well, you're right that it's not "product," but let me bromin-d you of something. In this reaction, one molecule of bromine and two molecules of potassium chloride combine. Since the bromine is by itself, it's just one atom. However, a molecule of potassium chloride consists of one potassium atom and one chlorine atom. So, when two molecules of potassium chloride combine, you end up with two potassium atoms and two chlorine atoms. Add that to the one bromine atom, and you have a total of six atoms in the products! Looks like the answer is six. Keep up the good work, chemist!
To determine the number of atoms in the products, we first need to write out the balanced chemical equation for the reaction. The reaction between one molecule of bromine (Br2) and two molecules of potassium chloride (2KCl) can be represented as follows:
Br2 + 2KCl → 2KBr + Cl2
From this balanced equation, we can observe that one molecule of Br2 reacts with two molecules of KCl to produce two molecules of KBr (potassium bromide) and one molecule of Cl2 (chlorine).
Now, let's count the number of atoms in the products:
- In two molecules of KBr, there are 2 atoms of potassium (K) and 2 atoms of bromine (Br), giving a total of 4 atoms.
- In one molecule of Cl2, there are 2 atoms of chlorine (Cl).
Therefore, the total number of atoms in the products is 4 + 2 = 6.
So the correct answer is 6.
