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:
To react with 0.5 moles of Zn 1 mole of HCl is required
Explanation:
Given data:
Number of moles of Zn = 0.50 mol
Number of moles of HCl = ?
Chemical equation:
Zn + 2HCl → H₂ + ZnCl₂
Now we will compare the moles of Zn and HCl through balance chemical equation.
Zn : HCl
1 : 2
0.50 : 2×0.5 = 1 mol
In order to react with 0.5 moles of zinc 1 mole of HCl is required.
The electrons in an atom that are in orbits away from the nucleus are called valence electrons. Nitrogen: 5, Silicon: 4, Oxygen: 6, Magnesium: 2.
<h3>What exactly is a positive electron and why is it significant?</h3>
Valence electrons are the electrons that reside in an atom's outermost shell. The role of valence electrons in controlling an atom's reaction makes them crucial. By writing an octet, you'll be enabled see how many protons fill the highest amount of energy.
<h3>What is valence defined simply?</h3>
In chemistry, valence, sometimes called valency, is a characteristic of an element who establishes how many other atoms of the element each atom can interact with. The phrase, which was first used in 1868, is used to represent both the broad capability of pairing of an element and its numerical value.
