Answer: 2.64 g of carbon dioxide that could be produced by the chemical reaction.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require = 2 moles of 
Thus 0.06 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 moles of give = 1 mole of 
Thus 0.06 moles of give =
of
Mass of 
Thus 2.64 g of carbon dioxide that could be produced by the chemical reaction.
Answer:
Both answer choice 2 and answer choice 3 are correct choices.
Explanation:
Biotic factors are living components in an ecosystem. They are living organisms which affect another living component in an ecosystem.
Antibiotic factors are non living components of an ecosystem. They are chemicals which affect living organisms.
The choice 2 is correct. The seeds spread out by mice is a biotic factor interacting with an antibiotic factor
Choice 3 is correct. The seeds in the soil grow into new trees are biotic factors interacting with an antibiotic factor
A polyatomic ion is a charged combination of individual atoms. The combination is regarded as a single unit when considering reactivity with other elements. Example: OH- which is a polyatomic ion made from one oxygen and hydrogen atom to form the negative hydroxide ion.
