She will most likely observe that the temperature does not change during melting because the heat absorbed is used to overcome intermolecular forces rather than to increase the kinetic energy of the particles if she measures the temperature of the water in the beaker.

Temperature does not change during melting because the heat absorbed is used to overcome intermolecular forces rather than to increase the kinetic energy of the particles.

As long as both ice and water are present in the beaker, the temperature of the water will not increase.

The freezing point of water is 0°C (273 K).

The water's temperature should be 0°C (273 K).

The following reaction: HF(aq) <--> H+(aq) + F-(aq) has an equilbirum constant (K) value of 7.2 x 10-4. This means that th
andriy [413]

Given an equilibrium constant value of 7.2 x 10-4 it is false to say that the reaction proceeds essentially to completion.

<h3>What is the equilibrium constant?</h3>

In a reaction, we can judge using the value of the equilibrium constant weather or not the reaction moves on to completion. If the reaction moves up to completion, it the follows that the value of the equilibrium constant ought to be large.

On the other hand, when we have a case that the equilibrium constant is small and is not so large, then the reaction does not proceed essentially to completion.

Given an equilibrium constant value of 7.2 x 10-4 it is false to say that the reaction proceeds essentially to completion.

Which of the following shows the correct path of blood through the heart and lungs?
jeyben [28]

Answer:

B

Explanation:

Always remember blood first flows from atria (remember A comes before V) to ventricles and the right side always carries deoxgenated blood to the lungs which then arrives through the left side when oxygenated

Number 39! Please explain step by step!!!
ahrayia [7]

Answer:

The answer to your question is The honda civic hybrid weights 13181.8 N or 1318.2 kg

Explanation:

Data

Weight = 2900 lb

Weight = ? N

mass = ? kg

1 kg ------- 10 N

0.22lb ---- 1N

Use proportions to solve this problem

                        0.22 lb ------------------- 1 N

                        2900 lb -----------------  x

                         x = (2900 x 1) / 0.22

                         x = 2900 / 0.22

                        x = 13181.8 N

                          1 kg ----------------------- 10 N

                           x     ----------------------- 13181.8 N

                           x = (13181.8 x 1)/10

                           x = 1318.2 kg
