For plant cells there is a cell membrane and a cell wall. For animal cells there is a cell membrane but no cell wall. Because it is rigid, I think it is most likely the cell wall, but if other organisms include animals, then it is the cell membrane.
Answer:
a)there would be no reaction
Explanation:
The activity series of metals has many functions. The one applicable to this problem is that it can be used to determine whether a reaction will occur or not. Also, based on the positions of metals in the series, we can know how reactive a metal is compared to another.
In a single displacement reaction, a metal replaces another metal based on their position on the activity series. Metals that are higher in the series are generally more reactive than others below them and so will displace them.
Would aluminum replace magnesium to form a new compound or would there be no reaction?
Magnesium is higher than aluminum in the activity series. Therefore it is more reactive than aluminum. No reaction will occur.
Answer:
The new volume is 7,606.96 Liter.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas in the balloon = 0.918 atm
= final pressure of gas in the balloon = 0.0012 atm
= initial volume of gas in the balloon =
= final volume of gas in the balloon = ?
= initial temperature of gas in the balloon =
= final temperature of gas in the balloon =
Now put all the given values in the above equation, we get:
The new volume is 7,606.96 Liter.
In chemical reactions, elements or compounds called reactants, are changed into other substances or compounds and elements called products. You cannot change one element into another in a chemical reaction. They are both important in order to classify the reaction.
