Explanation:

Red Blood Cell- Carry Oxygen - Large Surface area no nucleus

Sperm Cell- Fertilize the Egg- tail, lots of mitochondria

Palisade Cell- Photosynthesis- Lots of chloroplast and transparent

Palisade Cell; are plant cells located on the leaves, right below the epidermis and cuticle. So they carry Process of Photosynthesis and carry lots of chloroplast, and are transparent.

Sperm Cell; are gametes (sex cells) that are produced in the testes (gonad) of male human beings and animals. So They fertilize egg and have tail, lots of mitochondria enzyme in the head, streamlined.

Red Blood Cells; A type of blood cell that is made in the bone marrow and found in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body. So they carry oxygen and have large surface area and nucleus

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890
