The number of sandwiches that can made with  6 pieces of bread and 4 slices of cheese is 3 sandwiches.

<h3>What are limiting reactants?</h3>

Limiting reactants are those reactants which determine the amount of product that can be formed since they get used up in a reaction.

In the making of sandwiches from bread and cheese, the limiting reactant is the material that is used up.

The formula for making a sandwich is given below;

2 pieces of bread + 1 slice of cheese = 1 sandwich

6 pieces of bread can make 3 sandwiches

4 slices of cheese can make 4 sandwiches

Thus, bread is the limiting reactant.

Therefore, the number of sandwiches that can made with  6 pieces of bread and 4 slices of cheese is 3 sandwiches.

The number of sandwiches that can be made with  6 pieces of bread and 4 slices of cheese is 3 sandwiches.

<h3>What are limiting reactants?</h3>

The limiting reagent is the reactant that is completely used up in a reaction and thus determines when the reaction stops.

In the making of sandwiches from bread and cheese, the limiting reactant is the material that is used up.

Requirement of making sandwich related to the reaction is given below:

2 pieces of bread + 1 slice of cheese = 1 sandwich

6 pieces of bread can make 3 sandwiches

4 slices of cheese can make 4 sandwiches

Thus, bread is the limiting reactant.

Therefore, the number of sandwiches that can be made with  6 pieces of bread and 4 slices of cheese is 3 sandwiches.

___________ minerals are dark-colored because they contain _____________. a. Mafic; iron and/or magnesium b. Felsic; iron and/or
Likurg_2 [28]

Answer:

A. Mafic; iron and/or magnesium

Explanation:

Let's find the answer by naming some minerals and their chemistry.

Mafic minerals are dark-colored whereas felsic minerals are light-colored, thats way mafic rocks are dark-colored because they are mainly composed by mafic minerals and the other way around for felsic rocks.

But remember that mafic minerals as amphiboles, pyroxenes or biotites, involve in their chemical structure iron and/or magnesium. Although calcium and sodium can be incorporated in amphiboles and clinopyroxenes, they are not involved in orthopyroxenes and biotites. On the other hand, although potassium is involved in biotite and in some extent in amphiboles, this element is not involved in pyroxenes.

So in conclusion, mafic minerals are usually dark-colored because they involve iron and/or magnesium in their chemical structures.

URGENT!! This is timed, PLEASE HELP!
Andrews [41]

Answer:

99.24 gm of nitrogen .

Explanation:

molecular weight of ammonia = 17 , molecular weight of nitrogen = 28.

2 NH₃(g) + 3 CuO(s) → 1N₂(g) + 3 Cu(s) + 3 H₂O(g)

2 x 17 gm                      28 gm

( 34 gm )

34 gm of ammonia forms 28 gms of nitrogen

1 gm of ammonia   forms 28 / 34 gms of nitrogen

120.51 gn of ammonia forms 28 x 120.51 / 34 gms of nitrogen

28 x 120.51 / 34 gms

= 99.24 gms of nitrogen will be formed .
