answer: the variable part of an amino acid is the: SIDE CHAIN
Answer:
Answer A
Explanation:
because it had 6 electrons in the last shell so it needs two electrons to reach 8
Answer:
Nitrates.
Explanation:
They convert ammonia to nitrates.
We have to calculate the molar mass of AL(OH)₃
Atomic mass (Al)=27 amu
Atomic mass (O)=16 amu
Atomic mass (H)=1 amu
molecular weight= 27 amu+3(16 amu + 1 amu) =78 amu.
Therefore, the molar mass of Al (OH)₃ is 78 g/ mol
Now, we calculate the number of moles in 98.3 g of aluminum hydroxide.
78 g-------------------1 mol
98.3 g----------------- x
x=(98.3 g * 1 mol) / 78 g=1.26 moles.
Answer: 1.26 moles.
In a chemical reaction, the atoms of the starting species called reactants rearrange to form new substances which are the products of the chemical reaction. The identities of the atoms involved in the reaction remain the same. Their number also stays the same before and after the reaction
