Draw a graph of how kinetic energy & temperature are related
(LOOK AT THE PICTURE ATTACHED)
Answers
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.

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)
Answers
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.

how many moles are in 4.38 of AgNO2
Answers
Answer: 0.02 moles
Explanation:
The number of moles in 4.38 g of AgNO₂ is equal to 0.028 mol.
What is a mole?A mole can be described as a standard unit that can be utilized to calculate a given number of particles. The constituents counted are usually individually distinct but identical entities.
A mole of the substance can be used to calculate quantities of atoms, molecules, ions, or other particular particles. The quantity of matter can be described as measured by elementary entities.
The number of constituents present in one mole is equal to 6.023× 10 ²³ which is known as Avogadro’s constant.
Given, the mass of AgNO₂ = 4.38 g
The mass of one mole of AgNO₂ = 153.87 g
The number of moles of in 4.38 g of AgNO₂ = 4.38/153.87 = 0.028 mol
Therefore, the number of moles of AgNO₂ is equal to 0.028 mol.

If 42.68 ml of 0.43 M KOH is used to neutralize 18.40 ml of H, SO4, calculate
the concentration of the sulfuric acid solution.
Write the net ionic equation of this reaction
Answers
The concentration of the sulfuric acid : 0.499 M
The net ionic equation
2 OH ⁻(aq]+ 2 H ⁺ (aq] → 2 H ₂O (l]
Further explanationGiven
42.68 ml of 0.43 M KOH
18.40 ml of H2SO4
Required
the concentration of the sulfuric acid
the net ionic equation
Solution
Acid-base titration formula
Ma. Va. na = Mb. Vb. nb
Ma, Mb = acid base concentration
Va, Vb = acid base volume
na, nb = acid base valence
Input the value :
a=KOH, b= H2SO4
0.43 x 42.68 x 1 = Mb x 18.40 x 2
Mb = 0.499 M
The net ionic equation
Reaction
2KOH + H2SO4 → K2SO4 + 2H2O
2 K ⁺ (aq]+ 2 OH ⁻ (aq] + 2 H ⁺ (aq] + SO ₄²⁻(aq] → 2 K ⁺ (aq] + SO ₄²⁻(aq] + 2 H ₂ O (l]
canceled the spectator ions :
2 OH ⁻(aq]+ 2 H ⁺ (aq] → 2 H ₂O (l]
Why are fungi classified together?
They get their food the same way
They have a similar behavior
They grow in the same areas
They look alike
Answers
Answer:
A, they get their food in the same way.
Explanation:
Some fungi can be toxic or poisonous.
Example: mushrooms. Mushrooms typically are found in forests and meadows/plains.
Some fungi are glowing, brown, and in many forms/shapes.
In conclusion, fungi all get nutrient from the dirt they grew in, forests can be moist which gives fungi excellent places to form, usually around trees, because they can absorb plenty of nutrients from the dirt.

many mL should the patient take in each dose?
1) 500 mL
2) 10.0 mL
3) 2.50mL
4) 50.0 mL
5) 2.0 mL
Answers
10 ml should the patient take in each dose
Further explanationGiven
125 mg of penicillan ⇒ 4 times/day
The concentration = 250 mg/5 ml
Required
The volume of the dose
Solution
The mass of penicillan/day :
= 125 mg x 4 times
= 500 mg
The volume/day :
= 500 mg : 250 mg/5 ml
= 10 ml

Si en un laboratorio hay 300 moles de plomo y 300 moles de plata en cual de los dos casos la masa en mayor?
Answers
Answer:
Esto significa que la masa en las moles de plomo es mayor que en las de plata.
Explanation:
Las moles de los átomos representan la cantidad de átomos presentes. Para saber la masa de los átomos debemos convertir las moles a gramos usando el peso molecular de cada uno de los átomos (207.2g/mol para el plomo y 107.82g/mol para la plata).
La masa de plomo en 300 moles es:
300 moles * (207.2g / mol) = 62160g de plomo
Y la masa de plata es:
300 moles * (107.82g / mol) = 32346g de plata
Esto significa que la masa en las moles de plomo es mayor que en las de platawhat is the total number of atoms in 3.0 grams sample of neon?

= 3 g : 20,1797 g/mol
= 0.1487
The number of atoms :
N = n x No(No=Avogaro's number)
N = 0.1487 x 6.02 x 10²³
N = 8.95 x 10²²
