Draw a graph of how kinetic energy & temperature are related
(LOOK AT THE PICTURE ATTACHED)
Answer:
As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

how much time will it take a car traveling at an average of 75 mph to go a distance of 225 miles
Time taken = 3 hours
Further explanationGiven
speed : 75 mph
distance : 225 miles
Required
time taken
Solution
An equation of constant velocity motion
[tex]\large {\boxed {\bold {d = v \times \: t}}}[/tex]
d = distance = m
v = speed = m / s
t = time = seconds
Input the value :
t = d : v
t = 225 miles : 75 miles/hour
t = 3 hours
how many grams of PH3 will be produced if 6.0 l of H2 are used?
Mass of PH3= 6.086 g
Further explanationGiven
6.0 L of H2
Required
mass of PH3
Solution
Reaction
P4 + 6H2 → 4PH3
Assumed at STP ( 1 mol gas=22.4 L)
Mol of H2 for 6 L :
= 6 : 22.4 L
= 0.268
From the equation, mol PH3 :
= 4/6 x moles H2
= 4/6 x 0.268
= 0.179
Mass PH3 :
= 0.179 x 33,99758 g/mol
= 6.086 g

3. How many moles of glucose does 1.2 x 1024 molecules represent?
It measure the number of elementary entities of a given substance that are present in a given sample. 1.99 moles of glucose are present in 1.2 x 10²⁴ molecules.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance. The stoichiometry represents the number of moles. Mole is directly proportional to the number of given molecules.
Given number of atoms= 3.01x10²³atoms
we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
mole of glucose =given number of molecules of glucose ÷ 6.022×10²³(Avogadro number)
Substituting the values, we get
mole of glucose= 1.2 x 10²⁴÷6.02 x 10²³
mole of glucose= 1.99 moles
Therefore, 1.99 moles of glucose are present in 1.2 x 10²⁴ molecules.

"What are behavioral adaptations?
Why would an animal adapt it's behaviors?"
Explain why sometimes in a lab it seems like the conservation of mass isn’t accurate (but we know we haven't truly lost any mass)
Answer:
The law of conservation of mass states that in a closed system, the whole mass is conserved.
But the law of conservation of mass is not accurate sometimes in lab because in every chemical reaction, mass is converted into energy and not the whole mass can be conserved. Energy in chemical reaction can be created only by destroying the mass and not from any other means.
This is why, sometimes in a lab it seems like the conservation of mass isn’t accurate.

Why are we able to see planets at night?
Answer: Because planets do not have nuclear fusion, they do not produce their own light. Instead, they shine with light reflected from a star. When we see planets in the night sky, such as Venus, the so-called "Evening Star," we're seeing reflected sunlight.

When naming an ionic compound what must always
come first the anion or the cation? (Metal or
nonmetal)
Answer:
Cation / metal
Explanation:
When we named ionic compound we always write cation first. Let's take an example.
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations and ionic compound is formed. When we naming it we write " sodium " first which indicate sodium cation ( Na⁺) while anion which is Cl⁻ is always written at the end. When we naming ionic compound we ended the name of anion with "ide". Sodium indicate metal while chloride ion indicate non metal. it means metal comes first while naming ionic compound.
