Answer:
Thermal Energy and Chemical Reactions
The device controlled the activation as shown by the water holding room temperature for 15 seconds until activation by crushing the pills. The temperature rose 30° over two minutes,showing a measurable exothermic reaction from the Calcium Chloride dissolving in the water.
Pour 5mL water in a quart bag
Place Thermometer in the bag to make contact
Fill two gelatin 000 capsules with 1 gram of Calcium Chloride
Place capsules into the bag
Wait 15 seconds to crush the capsules while they are submerged in the water
-Temperature
0 seconds 75 degrees
15 seconds - Activation 75 degrees
30 seconds 85 degrees
60 seconds 95 degrees
90 seconds 104 degrees
120 seconds 105 degrees
Conclusion: During a reaction, thermal energy from the environment is converted into chemical energy stored in the products.

Which of the following is not a factor that is required for the formation of hurricanes?
A: Very high winds in the upper atmosphere
B: Ocean temperatures of atleast 80 degrees F
C: Low winds in the upper atmosphere
D: Warm, moist air
Answer:
Either A or C
Explanation:
Answer:
Hurricanes start with warm and cool climates for them to start. The stronger the climate, the stronger the hurricane is going to be. The winds are very high, going from a category 1, where it does damage bur not a lot, to a 5, where damage is really bad in some areas. So, your correct answer is C because in the hurricane, there needs to be high winds for it it become a hurricane

Water molecules can stick to other water molecules through which type of
bond?
Covalent
lonic
Oxygen
Hydrogen
Answer:
Hydrogen Bonds
Explanation:
Hydrogen bonds allow for hydrogens to bond to each other. They are the strongest type of intermolecular bonds.
Hydrogen bonds are dipole-dipole, and when water molecules are close to each other, the hydrogen bonds form between the hydrogen atoms.
Answer:
hydrogen bonds
Explanation:
this type of bond allows hydrogen atoms to bond together.
compared to the surface temperature and luminosity of massive stars in the main sequence, the smaller stars in the main sequence are
Answer:
Betelgeuse
b.Polaris
c. Aldebran
d.Sirius
e. The Sun
Explanation:
arent sure
In comparison with the surface temperature and luminosity of massive stars in the main sequence, the smaller stars in the main sequence are: cooler and less luminous.
A star is a giant astronomical or celestial object that contains a luminous sphere of plasma and bounded together by its own gravitational force.
Generally, a star typically comprises two (2) main hot gases and these are:
I. Hydrogen (H).
II. Helium (He).
Main sequence refer to stars that can fuse hydrogen atoms in its core, to form helium atoms.
Some examples of a main sequence include the following;
Sun (closest to planet Earth). Antares. Canopus. Vega. Betelgeus.The luminosity of a star can be defined as the total amount of light radiated by the star per second. Also, it is measured in Watts (W).
In conclusion, smaller stars in the main sequence are cooler and less luminous than massive stars in the main sequence.

BRAINLIEST What stage of cellular respiration uses the high-energy electrons from NADH and FADH2 to form ATP molecules?
Krebs cycle
Electron transport chain
Fermentation
Glycolysis
Answer:
Krebs cycle
Explanation:
Electron transport chain
AD+ and NADH: NAD+ is an electron carrier that accepts a pair of high-energy electrons to become NADH. The NADH carries the high-energy electrons to the electron transport chain where they are used to build high-powered ATP molecules.

what is europhication
Answer:
Eutrophication, the gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem such as a lake. The productivity or fertility of such an ecosystem naturally increases as the amount of organic material that can be broken down into nutrients increases.
Plants that thrive in this type of climate are most likely adapted to which of these conditions
Answer:
Plants Adapting
Explanation:
Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.

How does the use of wild-life/animals impact on the earth?
Answer:
Hope it helps...
Explanation:
Animals help us to save our environment. Some micro organisms such as bacteria help us clean the environment; others help plants by converting free nitrogen from air and feeding the roots. Some insects and earthworms help in agriculture by increasing fertility of the soil and also by increasing organic quality of soil.
Answer:
When a predator goes extinct, all of its prey is released from that predation pressure, and they may have big impacts on ecosystems. If there are too many deer, for example, they can really change the ecosystem because they can destroy forests, and they also carry diseases.
