Answer is: C is equal to 2, D is equal to 6 and E is equal to 1.
C, D and E represent number of electrons on each atomic orbital in sodium atom.
Electron configuration of sodium atom: ₁₁Na 1s² 2s² 2p⁶ 3s¹.
Atomic number of sodium is 11, it means that it has 11 protons and 11 electrons, so atom of sodium is neutral.
I believe the correct answer from the choices listed above is option 4. The 3 isomers of pentane have different structural formulas. <span>An </span>isomer<span> is a molecule with the same molecular formula as another molecule, but with a different chemical structure. Hope this answers the question.</span>
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.
Explanation:
Answer:
According to mass and volume, block density is 2 g/ml
Explanation:
Density is a measure, usually used in physics and chemistry, that relates the mass and volume of a solid or compound.
In general terms, the density is directly proportional to the mass, and inversely proportional to the volume, so increasing the mass will also increase the density.
The formula used to calculate the density is
ρ = 
Therefore, according to the mass and density of the block
ρ = 
= 2g/ml
Being the density of the block equal to 2 g/ml.
<em>The other options are not possible, because the values given do not correspond to the result of the equation.</em>
Answer:
glcolysis
Explanation:
Glcolysis uses glucose to create ATP within the cytoplasm of the cell.
