<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
Atomic mass of an atom is defined as the sum of number of neutrons and number of protons that are present in an atom. It is represented as 'A'.
Atomic number = Number of protons + Number of neutrons
We are given:
Number of protons = 6
Number of neutrons = 6
Number of electrons = 6
Atomic mass = 6 + 6 = 12
Hence, the correct answer is Option D.
First, we'll identify the beaker containing pure water as follows:
We'll take equal masses from each of the three beakers and measure the mass of each.
We'll then identify the density of each by using the rule : density =mass/volume
Pure water will be the liquid having density equal to 1 gm/cm^3
Then, we'll differentiate between the salt and sugar solution by measuring the conductivity of each solution. Salt solution is a good conductor while solution of sugar is a bad conductor.
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.
