Answer:
36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.
Explanation:
Number of slices of ham = 231
Given that each sandwich has 1 slice of ham.
Then 231 slices of ham will be in :
A single sandwich is made up of 2 bread slices , Then bread slices in 231 sandwiches will be :
Each bread slice is applied with 0.0500 ounce of mayonnaise.
Then 462 bread slices will have :
1 bread loaf = 13 bread slices
Then breads loves in 462 bread slices :
36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.
Answer:
F. 2NO + 02 —> 2NO
H. 4NH3 + 502 —> 4NO + 6H20
Explanation:
The law of conservation of mass states that matter can neither be created nor destroyed during a chemical reaction but can be convert from one form to another.
2NO + 02 —> 2NO
From the above, the total number of N on the left balance the total number on the right i.e 2 atoms of N on both side of the equation.
The total number of O on the left balance the total number on the right i.e 2 atoms of O on both side of the equation. This is certified by the law of conservation of mass.
4NH3 + 502 —> 4NO + 6H20
From the above, the total number of N on the left balance the total number on the right i.e 4 atoms of N on both side of the equation.
The total number of O on the left balance the total number on the right i.e 10 atoms of O on both side of the equation.
The total number of H on the left balance the total number on the right i.e 12 atoms of O on both side of the equation.
This is certified by the law of conservation of mass.
The rest equation did not conform to the law of conservation of mass as the atoms on the left side did not balance those on the right side
Can you show me the passage?
Explanation:
I can't guess it properly
Answer: Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.
