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.

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.

An aqueous solution of barium hydroxide is standardized by titration with a 0.102 M solution of perchloric acid. If 10.3 mL of b

Vesna [10]

<u>Answer:</u> The molarity of barium hydroxide solution is 0.118 M.

<u>Explanation:</u>

To calculate the concentration of acid, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of acid which is $HClO_4$

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is $Ba(OH)_2$

We are given:

$n_1=1\\M_1=0.102M\\V_1=24.0mL\\n_2=2\\M_2=?M\\V_2=10.3mL$

Putting values in above equation, we get:

$1\times 0.102\times 24.0=2\times M_2\times 10.3\\\\M_2=0.118M$

Hence, the molarity of $Ba(OH)_2$ solution will be 0.118 M.

60 POINTS + BRAINLIEST !! PLEASE HELP!!

To get moles. divide mass by molar mass.Molar mass of
Na is 23
and for Cl is 35.5.
the total molar mass of NaCl is 23+35.5 = 58.5mol/gUse the mass and divide by this number30.22g divide by 58.5mol/g and you will get 0.5166 mole.
Since the molecule has 1 Na to 1 Cl, and that the number of moles for NaCL is 0.5166. All of them would be 0.5166molesNa = 0.5166 x 1 = 0.5166molesCl = 0.5166 x 1 = 0.5166moles
to get number of atoms. Multiply your mole by Avogadro number which is 6.022x10^23Na = 0.5166 x 6.022E23 = 3.111x10^23Cl = 0.5166 x 6.022E23 = 3.111x10^23

A substance has a boiling point of 78 °C. Which of the following is true about the substance? (5 points) a It will also change f

vovangra [49]

Answer: If a substance has a boiling point of $78^{o}C$ then it is true that it will also change from a gas to a liquid at 78 °C while the gas loses energy.

Explanation:

The temperature at which vapor pressure of a liquid substance becomes equal to the atmospheric pressure is called boiling point of substance.

At the boiling point, liquid phase and vapor phase remains in equilibrium.

This means that as liquid phase changes into vapor phase and also vapor phase changes into liquid phase at the boiling point.

Thus, we can conclude that if a substance has a boiling point of $78^{o}C$ then it is true that it will also change from a gas to a liquid at 78 °C while the gas loses energy.
