your answer is B my friend
Answer: __3__Na2CO3 + __2__Ag3P → __2__Na3P + __3__Ag2CO3
Explanation:
In balancing equations you need to make sure the number of atoms before the reaction should be equal to the number of atoms after the reaction.
Before the reaction: We had 6Na, 9CO, 6Ag and 2p
After the reaction: We have 6Na, 9CO, 6Ag and 2p
And now we are sure that atoms before the reaction are equal to atoms after the reaction
Chemical reactions that are possible regarding the formation of the carbonic acid and the dissolving of calcite are 3.
So, the best option is A. 3.
Answer:
Humans, and most vertebrates, lack the enzyme cellulase.
Explanation:
Cellulose is a polysaccharide and it is made up of glucose however we the humans and other vertebrates lack the enzyme cellulase which is required to break down the cellulose molecule.
Some Animals such as cows, and termites have bacteria in the intestinal tract which can digest the cellulose as it has cellulase enzyme.
Thus due to symbiotic association with bacteria a few animals may digest cellulose indirectly.
The atmosphere protects the earth from many things, such as space debris,the suns radiation, etc
