I just had this question it is c
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.

15.3 litres of water will be produced if we take 1.7 litres of Hydrogen
Explanation:
Let's take a look over synthesis reaction;
<u> </u><u />
<u>Balancing the chemical reaction;</u>
<u> </u><u />
Thus, 2 moles of hydrogen molecules are required to form 2 moles of water molecules.
<u>Equating the molarity;</u>
<u /> =
(Since, the molecular mass of hyd and water is 2 and 18 respectively)
x=
x= 15.3 litres.
Thus,15.3 L of water will be produced if we take 1.7 litres of Hydrogen in a synthesis reaction.
The formula is SrCl2. hope this helps
