When the products of a reaction are hotter than the reactants, an exothermic reaction is happening. An exothermic reaction is a reaction that releases energy to the surroundings. The energy released should be more than what is absorbed in order to maintain the reaction.
Answer:
589 torr or mmHg.
Explanation:
We know that 1 atmospheric pressure is equal to 760 torr or 760 mmHg so calculate 0.775 atm pressure in term of mmHg and torr. We perform the following steps which is
1 atm -------- 760 torr or mmHg
0.775 atm ------- X
By cross multiplication we get
X = 760 x 0.775
X = 589 torr or mmHg
So we can conclude that if 0.775 atm is equals to 589 torr.
Answer:
In the picture, it's shown that the energy from the sun and carbon dioxide is absorbed by plants through the leaf and is used for cooking food in plants. It is also shown that nutrients and water needed for the plant is absorbed through the roots of the plant. And it's also shown that cooking results in the formation of Glucose and Oxygen in which oxygen is released into the atmospehere and the glucose is stored in the plant for its own needs.
Answer:
The right answer is "6 gm".
Explanation:
Given:
Amount of Li,
= 0.3 gm
Battery rated,
= 5 Ah per cell
Total number of cells,
= 4
The total power limit will be:
= ![5\times 4](https://tex.z-dn.net/?f=5%5Ctimes%204)
= ![20 \ Ah](https://tex.z-dn.net/?f=20%20%5C%20Ah)
hence,
The amount of Li in battery will be:
= ![(0.3)\times 20](https://tex.z-dn.net/?f=%280.3%29%5Ctimes%2020)
= ![6 \ gm](https://tex.z-dn.net/?f=6%20%5C%20gm)
(Allowed for transportation).
The answer is C.) Electron.
Hope this Helps!
P.s could i get a brainliest!
