From previous experiments, this chemical reaction is known to absorb of energy. The position of the piston is monitored, and it

is determined from this data that the system does of work on the piston during the reaction. Is the reaction exothermic or endothermic? exothermic endothermic Does the temperature of the water bath go up or down? up

Hello. Your question is missing data, which makes it difficult to answer it with exactness, but I will try to help you in the best possible way.

If the reaction absorbs energy it means that the reaction is endothermic. This is because endortemic reactions are those that absorb energy from the environment, as opposed to exothermic reactions that release energy into the environment.

In that case, if the reaction is absorbing energy, it is appropriate for the water bath temperature to drop.

4) A granola bar has a mass of 42.9 g and the granola bar contains 26.20% honey
nata0808 [166]

<u>Answer:</u>

The percentage of honey in one granola bar is 26.02 percent.  

<u>Explanation:</u>

The weight of 1 granola bar is 42.9 grams. The grams of honey that is present in one granola bar is equal to 26.02 percent of 42.9 = 11.16 g

Now the amount of honey in the factory is given as 189.5g the weight of total granola bars would be

                                     = 42.9/11.16 x 189.5= 728.25

So no. of granula bars =728.25/42.9 =16.9 that can be Approximated to nearly 17

Now if one box has 6 bars then 17 bars will have to fit inside three boxes

Describe the difference between at atom and an ion in regards to their substaomic<br> particles.
tangare [24]

Answer:

-Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.

-An atom has an equal number of protons and electrons. An ion has an imbalance between the number of protons and electrons.

-An atom has no electrical charge. Ions have an electrical charge because they have an imbalance of protons and electrons.

yan [13]

Answer:

Picking up marbles and placing them in a sack

Explanation:

The entropy of a chemical system is defined as the measure of disorder. Therefore a negative change in entropy is the movement to a more ordered state. The only option here which achieves a more ordered state, would be the first option.

Picking up marbles and placing them in a stack achieves more order, rather than the other options - that achieve more disorder.
