Answer:
False
Explanation:
Let's break down the equation PV=nRT.
P=Pressure
V= Volume
n= number of mole
R= the universal constant
T= Temperature
The = sign is the barrier between them. Whenever one side of the equation increases, something on the other side is directly impacted. When Temperature increases, so will pressure--and vise versa.

D. They use their knowledge to make public policy.
Scientists learn learn about the world through observation which helps in making scientific theories.
What are observations?
Observations are defined as a set of statements or facts which are recorded while conducting an experiment.Observations are made through sensing changes in the variables of the experiment.
It is specifically defined as an act of knowing or recording the changes in the variables of the experiment.Recording observations holds importance as recording observations avoid the experiment to be repeated over and over again.
It is important to note down observations so that the testing of hypothesis is made easier.There are four types of observations .Observations need to be descriptive and must be written in complete sentences and should include all the numerical data of the experiment.

Calculate the molarity of a solution prepared by dissolving 13.0 g of Na2CrO4 in enough water to produce a solution with a volume of 800. mL .
Express the molarity to three significant digits.
Answer:
molar mass sodium chromate = 162g
12.6g ÷ 162g/mole = moles sodium chromate (This is the solute)
molalrity or M = moles solute ÷ lliters of solution (You'll have to change given mL to L)

7. Put the following elements in order from smallest to largest atomic radius and explain
why:
C.0, Sn, Sr
Answer:
O, C, Sn, Sr
Explanation:
As per the periodic table trends, atomic radius of an atom deceases from left to right and increases down a group this is so because across a period or from left to right, number of protons increases that increases the nuclear charge and nuclear radius decreases. Down the group, atomic radius increases because energy level increases and distance between nucleus and outermost orbital increases.
The elements in order from smallest to largest atomic radius are:
O, C, Sn, Sr because as per the periodic table trends, oxygen (O) fall into right side of Carbon (C) in the periodic table and Strontium (Sn) and Tin (Sn) fall into down the group where Tin (Sn) is on the right side of Strontium (Sn).
Hence, the correct order is "O, C, Sn, Sr".

What is the relationship between the molecular mass and the molar mass of a substance?
Answer:
That is, the molar mass of a substance is the mass (in grams per mole) of 6.022 × 10 23 atoms, molecules, or formula units of that substance. In each case, the number of grams in 1 mol is the same as the number of atomic mass units that describe the atomic mass, the molecular mass, or the formula mass, respectively.

describe the relationship between kinetic energy and mass
Answer:
Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. ... Objects with greater mass can have more kinetic energy even if they are moving more slowly, and objects moving at much greater speeds can have more kinetic energy even if they have less mass
High solubility of ammonia in water what type of interaction is responsible for?
Answer:
The solubility of ammonia is mainly due to the hydrogen bonding and not the reaction. Other common substances which are freely soluble in water because they can hydrogen bond with water molecules include ethanol (alcohol) and sucrose (sugar).
Answer:
Hydrogen Bonding

The solubility of ammonia is mainly due to the hydrogen bonding and not the reaction. Other common substances which are freely soluble in water because they can hydrogen bond with water molecules include ethanol (alcohol) and sucrose (sugar).
What are the relative strengths of intermolecular forces based upon the findings in this activity
Answer:
Dispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond). Dispersion forces < dipole-dipole interactions < hydrogen bonds.
Answer:There are two kinds of forces, or attractions, that operate in a molecule—intramolecularand intermolecular. Let's try to understand this difference through the following example.
Figure of towels sewn and Velcroed representing bonds between hydrogen and chlorine atoms
We have six towels—three are purple in color, labeled hydrogen and three are pink in color, labeled chlorine. We are given a sewing needle and black thread to sew one hydrogen towel to one chlorine towel. After sewing, we now have three pairs of towels: hydrogen sewed to chlorine. The next step is to attach these three pairs of towels to each other. For this we use Velcro as shown above.
So, the result of this exercise is that we have six towels attached to each other through thread and Velcro. Now if I ask you to pull this assembly from both ends, what do you think will happen? The Velcro junctions will fall apart while the sewed junctions will stay as is. The attachment created by Velcro is much weaker than the attachment created by the thread that we used to sew the pairs of towels together. A slight force applied to either end of the towels can easily bring apart the Velcro junctions without tearing apart the sewed junctions.
Exactly the same situation exists in molecules. Just imagine the towels to be real atoms, such as hydrogen and chlorine. These two atoms are bound to each other through a polar covalent bond—analogous to the thread. Each hydrogen chloride molecule in turn is bonded to the neighboring hydrogen chloride molecule through a dipole-dipole attraction—analogous to Velcro. We’ll talk about dipole-dipole interactions in detail a bit later.

Ninety-five percent of igneous rocks
and metamorphic rocks are below
Earth's surface. Why is this true?
Answer:
This is so cause ...
Igneous rocks are formed when the molten material cools and hardens
and
Metamorphic rocks form when they are subjected to high temperatures and the great pressure of the rock layers above it.
So most of these rocks are found beneath the earth''s crust
(I hope im right... this might not be the perfect answer... but this as close as I can get.. I hope it usefull for u )
The given statement is true because igneous and metamorphic rocks are formed through processes that typically occur deep within the Earth's crust or mantle.
What are igneous rocks ?Igneous rocks are formed from molten magma that cools and solidifies beneath the Earth's surface, while metamorphic rocks are formed from existing rocks that are subjected to intense heat and pressure deep within the Earth.
After their formation, these rocks may remain buried beneath the Earth's surface due to ongoing geological processes such as plate tectonics, where rocks are pushed deeper into the Earth's mantle over time.
Additionally, erosion and weathering can expose rocks at the Earth's surface, but the majority of the exposed rocks tend to be sedimentary rocks rather than igneous or metamorphic rocks.
As a result, the vast majority of igneous and metamorphic rocks remain buried deep within the Earth's crust and mantle, making up the majority of the Earth's crust beneath the surface.
