Well it’s simple science not rocket science when an object falls. It’s gravitational potential turns into kinetic.
Answer:
the answer is : true ice and snow melts into water in sublimation
Answer:
Nitrogen
It has the least number of protons in the group hence making it smaller
Explanation:
According to periodic table, electronegativity increases across the period and decreases down the group.
Electronegativity is the tendency of an element to accept electrons towards itself.
In this group of elements, nitrogen has the highest electronegativity because it has the least number of protons in the group. Increase in the number of protons decreases an elements electro negative value.
The least electronegative element in that group is Antimony (Sb).
Electronegativity increases across the period and decreases down the group while electropositivity decreases across the period and increases down the group.
Your balanced equation for this reaction is:
HCOOH (aq) + H2O (aq) → HCOO- (aq) + H3O+ (aq)
So from the reaction, we can see when formic acid dissolved in water so H3O+ ions will be formed.
and we can see that it is a balanced equation as:
we have H atoms = 4 on both sides of the reaction
and C atoms = 1 atom on both sides of the reaction
and O atoms = 3 atoms on both sides of the reaction
So it is our final balanced equation of the reaction.
Answer:
A volumetric flask is lab glass or plasticware used to prepare a solution. It is used to make up a solution to a known volume. Volumetric flasks are used to measure volumes much more precisely than beakers or Erlenmeyer flasks.
