Answer:
2.5g
Explanation:
When the reaction goes into completion, they will produce 2.5g. This is complement the law of conservation of mass.
According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but transformed from one form to another".
- The mass of reactants and products in a chemical reaction must be the same.
- There is no change in mass in moving from reactant to product
- So, if we start with 2.5g of reactants, we must end with 2.5g of products.

= 0.019310344827586 kilogram/cubic meter
Answer: Exocytosis is the reverse of endocytosis. Quantities of material are expelled from the cell without ever passing through the membrane as individual molecules. By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.

3. Yes
4. No
5. Yes
6. No
Explanation:
Use the reactivity series. If the element is above it, it is more reactive. More reactive elements can displace less reactive elements from their compounds.
