Answer:
Controls the movement of substances into and out of the cell.
Answer:
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is: AB→A+B. Most decomposition reactions require an input of energy in the form of heat, light, or electricity.
Explanation:
Hopefully this helps :)
The main difference between the two is that emission spectrum has different colored lines in the spectrum, an absorption spectrum has dark colored lines in the spectrum.
The density of Jena’s smoothie is 0.667 g/mL.
Mass = 200 g
Volume = 300 mL
Density = mass/volume = 200 g/300 mL = 0.667 g/mL
Answer:
3). 1.30 × 10^(24) molecules
Explanation:
From avogadro's law which state that equal volume of all gases at the same temperature and pressure contain the same number of molecules.
We can relate it to this question as;
V₁/n₁ = V₂/n₂
Where;
V₁ is initial volume
n₁ is initial number of molecules
V₂ is final volume
n₂ is final number of molecules
Thus at STP, we have V₁ = V₂ and as such Plugging in the relevant values gives;
5/(1.30 x 10^(24)) = 5/n₂
n₂ = 1.30 x 10^(24) molecules
