Answer: ∠2 and ∠4 are vertical angles.

Explanation: We are given two linear lines that intersect each other and forms angles.

Theorem: When two lines intersect, the vertical angle are congruent to each other which means that the two angles are equal. Vertical angles are the angles that are opposite to each other.

In the given figure, ∠2 and ∠4 are opposite to each other, hence they are considered as vertical angles.

∠2 = ∠4 (From above theorem)

Avogadro's law states that the _____ of a gas is directly proportional to the _____ of the gas when _____ stay the same
attashe74 [19]

Answer:

The three blanks for this answer, are

1. volumen

2. moles

3. Temperature and pressure.

So, Avogadro's law states that the volume of a gas is directly proportional to the moles of the gas when temperature and pressure stay the same

Explanation:

Imagine you have 10 moles of a gas which is contained in 50 L. How many moles of that gas, you will have if the volumen has been reduced to 10 L. (Of course, don't forget that T° and pressure are the same)

There is an equation like this, initial moles /initial volume = moles at the end/volume at the end, (Avogadro law for gases), so 10/50 =moles at the end/10.  When u operate, moles at the end = (10 x 10) / 50.

Moles at the end are 2. Did u get it?. Volumen has been reduced, also the moles.
