Gas hydrates are compact chemical structures made of natural gas andA. halite.
B. water.
C. manganese.
D. petroleum.
Answers
Answer:
Option-B (water) is the correct answer.
Explanation:
Gas hydrates are made up of Solid-Ice water and a natural gas like Methane gas trapped in the lattice of ice water. Gas hydrates are mainly found deep down in the sea where the atmospheric pressure is greater than 1 atm.
Generally Gas hydrates have two main applications.
a) It stabilizes the sea floor other wise its melting will cause land sliding in sea floor.
b) Secondly, it traps a green house gases like Methane, if released these gases could produce Climate changes.
Answer:
B) water
Explanation:
Gas hydrates are essentially crystalline solid cage like structures in which small molecules are trapped in a network of frozen water molecules. The trapped gas molecules are usually methane which is a natural gas.
These methane hydrates are formed when methane and water combine under high pressure conditions usually prevalent in the ocean floors. Gas hydrates are also regarded as a powerful candidates for the production of cleaner energy.

What is used up in and stops a chemical reaction? (a) percent yield (b) limiting reactant (c) theoretical yield (d) excess reactant
The correct option is (b)
Explanation:
A chemical reaction is a chemical combination,rearrangement or disintegration of chemical substance(s) (called reactants) to form new chemical substance(s) (called products).
A limiting reactant is the reactant that is totally used up during the course of a reaction. When this reactant is used up, it limits the amount of products formed and eventually stops the chemical reaction.

Answers
Answer:
Canola Oil
Explanation:
The data given is as;
Oil Melting Point / Freezing Point
Canola Oil 10 °C
Corn Oil -11 °C
Sunflower Oil -17 °C
Peanut Oil -2 °C
When the mixture of these oils is cooled to 5 °C only the Canola oil will solidify because it has a melting point of 10 °C and exists in solid state below 10 °C (Freezing Point). Therefore, it can easily be separated from remaining mixture which is present in liquid state.

The polarity of a water molecule comes from the uneven distribution of electron density of hydrogen and oxygen atom. The oxygen in the water molecule is more electronegative than the hydrogen. Water has a partial positive charge near the hydrogen atom and a partial negative charge near the oxygen atom. The result of this electrostatic attraction results in the bond called hydrogen bond. Also, because of this bond, it has the ability to dissolve most of the solutes due to its polarity and bonding.

In AZX notation
A - Represents the mass number of atom.
Mass number = number ofprotons + number of neutrons.
It is shown atthe above of the left side of theatom.
Here it is 42.
Z - Represents the atomic number.
Atomic number = number of protons.
It is shown at the bottom line of the left side of the atom.
Here it is 20.
X - Represents the symbol of the atom.
Here X is Ca.
The symbol for an isotope of Calcium-42 corresponding to the isotope notation is
Isotopes are atoms of the same element that have the same number of protons (atomic number) but different numbers of neutrons (mass number).
In case of Calcium-42,
- The chemical symbol for calcium (X) is Ca.
- The mass number (A) of the isotope is 42, which is the sum of the number of protons and neutrons in the nucleus of the atom.
- The atomic number (Z) of calcium is 20, which is the number of protons in the nucleus of the atom.
Therefore, the chemical symbol for the isotope Calcium-42 is
