A dibasic acid is an acid that has two oxygen ions to donate to a base in an
acid-base reaction.
Therefore, a dibasic molecule has two replaceable hydrogen atoms.
<span>Energy is required to produce a chemical change during (2) electrolysis, given that it is the only stage which includes only a chemical change. The other options include physical changes as well.</span>
a. malleable, flexible, and ductile
Answer:
Phosphorous has the smallest atomic size.
Explanation:
As we know these elements belong to same period means there valence shell is the same. So moving from left to right along the period the shell number remains constant but the number of protons and electrons increases. So, due to increase in number of protons the nuclear charge increases hence attracts the valence electrons more effectively resulting in the decrease of atomic size.
Elements and their atomic radius are as follow,
<span><span>Magnesium 0.160 nm

Aluminium 0.130 nm

Silicon 0.118 nm

Phosphorus <span>0.110 nm</span></span></span>
Answer:
Well he couldn't be pushed back as there isn't a place for him to float back, because of Newton's third law: Every force has an opposite force when Eugene pushes, he will float backwards
