Answer:
B. move more quickly
Explanation:
As a sample of matter is heated, we know that the particles begins to move more quickly.
This is because the temperature of a substance is directly proportional to the average kinetic energy of a system.
- As the temperature increases, the body gains more kinetic energy
- This is translated to the particles of the medium.
- Then they begin to move quickly and very fast enough.
Answer: The temperature goes up.2.The piston doesn't move in and out.3.Heat flows out.4. Amount of heat evolved is +285 kj/mol
Explanation:
The temperature in the water bath will rise because heat being evolved is absorbed it.Based on principle of constant pressure, the piston doesn't move in and out.Since the reaction is a combination reaction, heat will be evolved.
Your wight on the earth is greater because it has more gravitational pull whilebon the moon your weight is lower beacause of less gravitational pull.

This site is used for learning, so to give a better understanding, here is a walkthrough.
So let's create a question:
Can a molecule have a dipole moment if it has no polar covalent bonds?
Here's the answer to that question:
Even though a molecule contains only one element, it can have a persistent dipole moment. The most common example is ozone (trioxygen). It is curved and has a partial positive charge on the center oxygen atom (similar to sulfur dichloride).
Permanent dipole moments are caused by an unequal, directed charge distribution within a molecule, not by changes in electronegativity. Such charge distributions are frequently caused by so-called "polar covalent bonds," which occur between atoms with markedly varying electronegativity. However, they are not the sole explanation.
So using this information, try to answer this question on your own.
