Answer:
heated particles speed up, vibrate faster and gain kinetic energy, and the particles move farther apart. cooled particles slow down, vibrate slower and lose kinetic energy. room temperature particles would be in between the two. i think :)
Explanation:
The measures of angles P and S
A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. A parallelogram is PQRS. Parallelograms come in 4 different varieties, including 3 unique varieties. The four varieties are rhombuses, parallelograms, squares, and rectangles.
P and S are adjacent angles in the parallelogram PQRS, and the total of all adjacent angles in a parallelogram is 180 degrees.
Angle P + Angle S equals 180 degrees.
More information is needed, though, to calculate certain angles.

Answer:
The percent composition of fluorine is 65.67%
Explanation:
Percent Composition is a measure of the amount of mass an element occupies in a compound. It is measured in percentage of mass.
That is, the percentage composition is the percentage by mass of each of the elements present in a compound.
The calculation of the percentage composition of an element is made by:
In this case, the percent composition of fluorine is:
percent composition of fluorine= 65.67%
<u><em>The percent composition of fluorine is 65.67%</em></u>
Answer:
34.2 g
Explanation:
In the Hall-Heroult process, Al³⁺ (from Al₂O₃) is reduced to Al. The reduction half-reaction is:
Al³⁺ + 3 e⁻ ⇒ Al
We can establish the following relations:
- 1 A = 1 c/s
- 1 mole of e⁻ has a charge of 96468 c (Faraday's constant)
- 1 mol of Al is produced when 3 moles of e⁻ circulate
- The molar mass of Al is 26.98 g/mol.
Suppose a current of 6800 A is passed through a Hall-Heroult cell for 54.0 seconds. The mass of Al produced is:
