ventilation

humidity

insulation

surface temperature

Explanation:

ventilation-well ventilated room could increase the body's cooling process

humidity-being in a humid location could cool the body at a slower rate

insulation-a body wrapped in something will cool slower then one not

surface temperature-a body on a hit surface will cool slower than one on a cold surface

The potential energy on a spring is proportional to the square of which of these quantities

erica [24]

The magnitude of the force required to change the length of a spring-like object is directly proportional to the spring constant and the displacement of the spring. Elastic potential energy is directly proportional to the square of the change in length and the spring constant.

What is the pOH of 0.5 M KOH?

jenyasd209 [6]

Answer:

pOH = 0.3

Explanation:

As KOH is a strong base, the molar concentration of OH⁻ is equal to the molar concentration of the solution. That means that in this case:

[OH⁻] = 0.5 M

With that information in mind we can calculate the pOH by using the following formula:

pOH = -log[OH⁻]

pOH = -log(0.5)

pOH = 0.3

Molecules that are optically active due to the tetrahedral arrangement of bonds around the carbon atom are often referred to as

morpeh [17]

Answer:
Molecules that are optically active due to the tetrahedral arrangement of bonds around the carbon atom are often referred to as Chiral Molecules.

Explanation:
Chiral molecules have stereogenic centers. When plane polarized light is fall on these compounds they rotate the light either in clockwise or anti clockwise direction. The mirror images of chiral moleculecules are non-superimposable. Below few examples for molecules containing chiral centers are given.

Iron pyrite, FeS2, is known as Fool's Gold because it is a shiny yellow solid which is similar in appearance to gold. Iron pyrit

kobusy [5.1K]

Answer:

Explanation:

The algebraic sum of all the oxidation numbers of all atoms in a neutral compound is zero.

In order to know the formula of the negative Sulfur ion in pyrite, we must determine its oxidation state.

Let us make the make the oxidation number of sulfur = x

Therefore, FeS₂:

+2 +2x = 0

+2 = -2x

x = -1

The formula of the negative ion is S⁻
