1) it allows air, water and nutrients (salts) to penetrate the soil and reach the plant roots and not just stay on the surface of the soil where the plant can't absorb it.
2721.55422g
Explanation:
First, step is to find out how much is 1pound in grams.
So,
1 POUND x (1 KG/2.204 POUND) x (1000G/1 KG) which is equal to 453.59g
Here, we got that 1 pound is equal to 453.59g.
In the question, it is given that the weight of the baby is 6 pound.
To convert 6 pounds into grams, we need to multiply 6 pounds with 453.59 g,
6pounds x 453.59g = 2721.55422 g
Hence, the weight of the 6-pound baby in grams will be 2721.55422 grams.
Answer:
Explanation:
Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. Include all free radicals by right-clicking on an atom on the canvas and then using the Atom properties to select the monovalent radical.
Answer is: <span>the pressure of the gas is 9,2 atm.
</span>p₁ = 4,0 atm.
T₁ = 300 K.
V₁ = 5,5 L.
p₂ = ?
T₂ = 250 K.
V₂ = 2,0 L.
Use combined gas law - the volume of amount of gas is proportional to the ratio of its Kelvin temperature and its pressure.<span>
</span>p₁V₁/T₁ = p₂V₂/T₂.
4 atm · 5,5 L ÷ 300 K = p₂ · 2,0 L ÷ 250 K.
0,0733 = 0,008p₂.
p₂ = 9,2 atm.
Answer:
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
