Answer:
Filters are used to lower the amount of pollutants released into the environment.
Explanation:
The major waste products from nuclear reaction are nuclear waste and steam. Nuclear waste is stored, not released into the environment. Steam is released but it is pure H2O and does not require filtration. This makes the statement false.
Answer:
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

Answer:
The correct option is 9
Explanation:
The number of dots in the electron dot symbol for chlorine = 7
The arrangement are 2 each on three of the for sides and one dot on the forth side
Therefore, given that the electronic configuration of the different orbital levels are;
1st = 1s²
2nd = 2s²2P⁶
The element that will have 7 electrons in the outermost shell similar to that of chlorine will have an electronic configuration as follows;
1s²2s²2P⁵, such that there are a total of 9 electrons (2 + 2 + 5 = 9) with 7 of the electrons in the outermost shell and 7 dots surrounding the element's symbol
However, since the for the atom to be electronically neutral, there are equal number of electrons and protons in the atom and given that the atomic number = The number of protons in the nucleus of the atom, we have that the atom having 7 dots surrounding its symbol similar to chlorine, Cl, has an atomic number of 9.
Answer : The mass of carbon dioxide produced will be, 303.424 grams.
Explanation : Given,
Mass of butane = 100 g
Molar mass of butane = 58 g/mole
Molar mass of carbon dioxide = 44 g/mole
The balanced chemical reaction will be,
First we have to calculate the moles of 
Now we have to calculate the moles of 
From the balanced reaction, we conclude that
As, 2 moles of butane react to give 8 moles of carbon dioxide
So, 1.724 moles of butane react to give 
moles of carbon dioxide
Now we have to calculate the mass of
Therefore, the mass of carbon dioxide produced will be, 303.424 grams.
Answer:
Heyo
Explanation:
Humus is often used by to fertilize the soil. Aside from adding nutrients, it also loosens the texture of the soil. With a freer texture, air and water can more easily penetrate, and oxygen can reach the plant’s root system faster. Some experts also believe it has the ability to prevent plants from getting hit by the disease.
hope this helps!
