1. A student predicted the reaction between hydrogen and oxygen gas would yield 125
mL of water. However, after measuring the water formed in the reaction, the
student determined that only 110mL of water was actually formed. What is the
percent yield of this reaction?
Answer:
88%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
110/125 = 0.88
0.88 x 100 = 88%

Which of these layers is found directly above the Earth's core?
Group of answer choices
Outer core
Mantle
Inner core
Crust
Answer: Mantle
Explanation:
there are 3 layers of the earth- core, mantle and crust. The layer found directly above the earth's core is the mantle.
Answer:
The answer depends on what you are taking about: the outer core or the inner core?
Answer: Mantle
Explanation:
If you find a picture of the Earth's layers, you can see that the inner core is the bottommost layer. However, if you combine the Inner Core and Outer Core, that could be determined as the Earth's core.
I would chose the Mantle because if the two cores are combined, the layer directly above them is the Mantle.

Stimulus refers to events that produce a response in the body due to changes in the environment , therefore response to stimulus is essential for an organism to survive and adapt in its environment.
What is a stimuli?A stimuli is any sensation or action that produces a response in a tissue or organ.
Stimulus is the plural noun of stimuli.
There are two types of stimulus:
external stimulus which comes from outside the body internal stimulus which comes from within the body.The body responds to stimulus in order to adapt to changes in both its external and internal environment.
For example, when the envrionment is hot, the brain receives stimulus from heat receptors and then we start to sweat in order to cool down.
Stimulus are received by sense organs in the body
There are five sense organs in the body;
eye - for sightear - for hearing nose - for smellingskin - for feeling mouth - for tastingSensory receptors in sense organs receives stimulus and send it to the brain through the sensory neurons.
The brain processes the stimulus and send messages back through motors neurons to appropriate organs and tissues to act in response to the stimulus.
Therefore, response to stimulus is essential for an organism to survive and adapt in its environment.

Why do hot packs and cold packs eventually return to room temperature?
Answer:
Temperature will revert to room temperature after the substance reacts fully. Heat energy flows between the chemical bonds of the added substance and water to the surroundings (elsewhere in the water, the beaker, a student's hand that touches the beaker).
Explanation:
Hot packs and cold packs eventually return to room temperature because of thermal equilibrium
Temperature is the degree of hotness or coldness of a body. We have to note that bodies often tend to attain thermal equilibrium with the surroundings. Hence heat flows from or to the body as required.
Hence, the need to attain thermal equilibrium with the environment is the reason why hot packs and cold packs eventually return to room temperature.
