We can change or shift vehicle weight by

a) change in speed (by accelerating and by braking)

b) change in direction (turning left or right)

Now there is a physics behind the shift in weight based on braking and accelerating.

You can shift weight to the front of your vehicle by braking.

Similarly, we can shift weight to back by accelerating.

Bending or turning left will transfer weight to right

Bending or turning right will transfer weight to left

Answer:

B and C

Explanation:

I think the answer correct is C because you never know in what temperature the block of ice is going to melt but if it says select all that apply its possible that B might be useful.

The potential energy diagram shows the gain and loss of potential energy as water molecules decompose into hydrogen and oxygen.

Dovator [93]

Answer:

The diagram with the five labels of the parts is in the image attached. Please, see the image.

Explanation:

1) General explanation: a potential chemical energy diagram is used to show how the reactants gain energy until they reach the activation energy, form the activated complex, and release part of the energy to form the products.

The difference between the chemical potential energy of the products and the reactants is the enthalpy of the reaction:

ΔH rxn = ΔH products - ΔH reactants.

The labels that correspond to each part of the diagram are explained next.

2) Reactants:

This is the substances at the start, so they appear on the left bottom side of the diagram.

3) Activation energy:

It is the energy that the reactants must reach (the highest point) in order to the reaction occurs.

4) Activated complex:

This is the intermediate state and of highest energy. The reactants have formed a complex at mid way between the reactants and the products.

5) Products:

These are the substances formed when the reaction is completed. They are lower in energy than the activated complex. They can be either higher or lower in energy than the reactants. The products are shown to the right of the diagram.

6) Enthalpy of the reaction:

The enthalpy of the reaction is the difference in energy of the products and the reactants. In this case, since, the products are higher in energy, it means that the reaction absorbed energy and it is an endothermic reaction.

What is best classified as a physical change?

andrew-mc [135]

A physical change is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not. Physical changes can further be classified as reversible or irreversible. The melted ice cube may be refrozen, so melting is a reversible physical change.

Denver, Colorado (altitude above sea level is 5,280 ft) has an atmospheric pressure of 633. mm Hg. Calculate the boiling point o

Fed [463]

Answer:

T2 = 94.6 C

Explanation:

Use Clausius-Clayperyon equation.

ln P1/P2 = ∆Hvap/R (1/T2 - 1/T1) where R = 8.314 J/mol-K and T is in degrees K

P1 = 760 mmHg

P2 = 630 mmHg

T1 = 373 K

T2 = ?

∆Hvap = 40.7 kJ/mole

R = 0.008314 kJ/mole-K (NOTE: change R to units of kJ)

Plug in and solve for T2

ln 760 mmHg/630 mmHg = 40.7 kJ/mole (1/T2 - 1/373K)

T2 = 367.74 K = 94.6 C
