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.

When naming an ionic compound what must always
come first the anion or the cation? (Metal or
nonmetal)

Answers

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.

Two people are pushing on a shopping cart from opposite sides. When will the motion of
the shopping cart change?
A. When the two forces are equal
B. When the forces acting on it are unbalanced
C. When both people stop applying a force
D. When the two people push with the same force

Answers

Answer:

The answer is B

The motion of the shopping cart will change when the forces acting on the shopping cart are unbalanced. Option B is correct.

According to Newton's first law of motion, an object will remain in its state of motion (either at rest or moving with a constant velocity) unless acted upon by an external force. In this case, the shopping cart is initially at rest or moving with a constant velocity due to the balanced forces exerted by the two people pushing it from opposite sides.

If the two forces applied by the people pushing the cart are equal the cart will continue to move in the same direction with the same velocity. The forces cancel each other out, resulting in a balanced force situation, and there is no change in motion.

However, if the forces applied by the two people pushing the cart are unequal, the forces are unbalanced. This will result in a net force acting on the shopping cart, causing an acceleration and a change in its motion. The cart will either start moving if it was initially at rest or change its speed and/or direction if it was already in motion.

When both people stop applying a force is incorrect because, the cart's motion will continue unchanged if it was already moving with constant velocity due to the absence of any unbalanced forces.

Hence, B. is the correct option.

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.

3. How many moles of glucose does 1.2 x 1024 molecules represent?

Answers

The answer is two miles


1 mole of any substance has 6.02 x 1023 molecules. For getting thenumber of moles we can divide 1.2 x 1024/6.02 x 1023 and we receive 2 moles.

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.
