<span>A transformation that is invariant with respect to distance. That is, the distance between any two points in the pre-image must be the same as the distance between the images of the two points.</span>
Answer:
The sum of the coefficients in the balanced equation is 11
Explanation:
A reaction where an organic compound reacts with oxygen to produce carbon dioxide and water is called combustion.
The balance reaction of combustion for methanol is:
2CH₃OH (l) + 3O₂(g) → 2CO₂(g) + 4H₂O (g)
Coefficients from stoichiometry are 2, 3, 2 and 4
Sum = 2 + 3 + 2 + 4 = 11
Answer:
Explanation:
We are asked to find the density of a brick. Density is a substance's mass per unit volume. The formula for calculating density is as follows.
The mass of the brick is 100 grams and the volume is 25 cubic centimeters.
Substitute the values into the formula.
Divide.
The density of the brick is <u>4 grams per cubic centimeter.</u>
Radon is a colorless, odorless, radioactive gas. It is also a leading cause of lung cancer. Ventilation is essential.
