When the reaction shown is correctly balanced, the coefficients are<br> Li + Br2 - LiBr
Natasha_Volkova [10]

2, 1, 2

Explanation:

Given equation of reaction:

             Li + Br₂  → LiBr

In balancing any chemical equation, they must obey the law of conservation of matter. This law suggests that the number of moles of reactants and products must be the same in a chemical reaction.

This suggests that no amount of matter is lost during a chemical reaction.

The reaction above is a combination reaction in which two species combines to give a product.

 To balance chemical reactions, we can simply inspect and assign the appropriate coefficient to the reactants and products. The coefficients should be whole numbers.

Also, the approach here would be mathematical where we would derive simple and solvable algebraic expressions to address the problem.

 Assign alphabets a, b and c to the species;

          aLi + bBr₂  → cLiBr

Conserving Li;     a  = c

                   Br;     2b = c

let      b = 1;

         c = 2

          a = 2

The coefficients are 2, 1  and 2

The balanced equation is:

           2Li + Br₂  → 2LiBr

What is the difference between a mixture and compound
bonufazy [111]
A compound is made up of a single type of molecule. A mixture, on the other hand, is made up of different substances that can be distinguished from one another.
As an example:
Water (pure water) is a compound since it's only made up of water molecules
Seawater is a mixture since it is made up of water molecules and soluble salts

Use the balanced equation to solve the problem.
harkovskaia [24]

Answer:

4.20 moles NF₃

Explanation:

To convert between moles of N₂ and NF₃, you need to use the mole-to-mole ratio from the balanced equation. This ratio consists of the coefficients of both molecules from the balanced equation. The molecule you are converting from (N₂) should be in the denominator of the ratio because this allows for the cancellation of units. The final answer should have 3 sig figs because the given value (2.10 moles) has 3 sig figs.

1 N₂ + 3 F₂ ---> 2 NF₃

2.10 moles N₂        2 moles NF₃
---------------------  x  ---------------------  =  4.20 moles NF₃
                                  1 mole N₂

A 75 gram bar of gold is cut into three equal pieces. How does the density of each piece compare to the density of the original
11111nata11111 [884]

Answer:

You should know that density is the relation between, mass and volume as it is described in this equation: d = m/v. As the mass doesn't change in each piece, you will see that volume is less than the original, that's why each piece is 1/3 the density of the original bar or, you can also see, that you have increase by 3, the density original.
