Where do glaciers come from
Answers
Answer:GLACIERS ARE MADE UP OF FALLEN SNOW OVER MILLION YEARS, IN MOST OF POLAR REGIONS IT TURNS TO ICE AND WILL FLOW DOWNWARDS AND OUTWARDS UNDER ITS OWN PRESSURE

Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is,
As we know that nitrogen has '5' valence electrons and hydrogen has '1' valence electron.
Therefore, the total number of valence electrons in = 5 + 3(1) = 8
According to Lewis-dot structure, there are 6 number of bonding electrons and 2 number of non-bonding electrons.
The Lewis dot structure of student A is wrong because there is a coordinate bond present between the nitrogen and hydrogen is not covalent.
The correct Lewis-dot structure of is shown by the student B.

D. Pressure and temperature
Answers
Answer:
D. Pressure and temperature.
Explanation:
The answer is D because when water molecules (H2o) have heat and pressure added it will boil. For exampe if your cooking pasta, you add water to your pan and when you add heat and put the lid of the pan it will boil.

A reducible molecule undergoes hydrogenation when hydrogen is added to it. Alkenes, alkynes, and aromatic molecules that are unsaturated are converted into saturated products through the hydrogenation of hydrocarbons.
What is hydrogenation ?
A chemical reaction known as hydrogenation occurs when molecular hydrogen interacts with another substance or element, typically in the presence of a catalyst made of nickel, palladium, or platinum. The method is frequently used to saturate or decrease organic molecules.
With the aid of nickel or palladium catalysts, unsaturated hydrocarbons are added to hydrogen in this process to create saturated hydrocarbons. Example: Applying an addition reaction to ethane in the presence of catalysts like nickel or palladium allows for the conversion of ethane.
When making plastics, unsaturated hydrocarbons are incredibly helpful organic substances. Egg cartons, disposable cups, and other practical things are made of polystyrene. Alkenes are utilized in the production of industrial compounds like alcohol.
Thus, A reducible molecule undergoes hydrogenation when hydrogen is added to it.

Answer: The metal probably increases reaction rate by either holding reactant molecules in the correct orientation to react or by weakening or breaking bonds in reactant molecules to make them more reactive. This is an example of heterogeneous catalysis.
Explanation: It is heterogeneous catalysis because the catalyst is a solid and the reactants are gases. In heterogeneous catalysis, the catalyst is in a different phase than the reactants.
