Hello,
Your brainliest answer would be:
1A. Both involve ion movements
1B. Passive transport moves ions from high concentration to low, using no metabolic energy.
2A. Both passive transport processes.
2B. Diffusion refers to the movement of any chemical from one place to another, whereas osmosis exclusively from one place to another.
Plz mark me brainliest!
Hope this helps!
The formula unit equation for the given reaction occurring in water is
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).
<h3>What is chemical reaction?</h3>
Chemical reactions are those reaction in which reactant molecules react with each other for the formation of product.
When calcium sulfide reacts with iron (II) bromide for the formation of iron(II) sulfide and calcium bromide will be represented through the following equation:
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq)
Above reaction best explains the formula unit of given reaction as all valency of atoms are satisfied there.
Hence, the required formula unit is CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).

False , they form water or ice crystals
The important thing to note is the reason why electron react is due to the instability of the electrons. All elements wants to aim the electron configuration of the noble gases. This is the most stable form in which each of the orbitals are sufficiently filled. When it comes to bonding, the order of reactivity is: alkynes > alkenes > alkanes. Alkynes are compounds with triple bonds, alkenes with double bonds and alkanes with single bonds. The single bonds are called saturated hydrocarbons. This is because they have reached stability, so it is quite difficult to react this with reducing or oxidizing agents. Alkynes and alkenes are unsaturated hydrocarbons. They readily react with reducing and oxidizing agents so as to become saturated, as well. The underlying principle for this is that single bonds contain sigma bonds which is the head-on overlapping of electrons. These is the strongest type of covalent bond. Double and triple bonds contain pi bonds which is the side overlapping of electrons orbitals. Hence, these electrons would be easily separated making it more reactive especially during protonation.
