IT IS NOT POSSIBLE TO RETRIEVE A BOTTLE OF SULFATE BECAUSE SULFATE DOES NOT EXIST AS A DISTINCT CHEMICAL COMPOUND.
Sulphate is a polyatomic ion. A polyatomic ions refers to group of atoms that carry charges. Sulfate carries a charge of +2. Sulfate is a very reactive ion, thus, it can not be found existing on its own, it is always found in combination with other elements, such elements include H2SO4 and CaSO4.
Answer:
H2 + I2 --> 2HI
Explanation:
The two reactants are diatomic molecules because they contain two atoms of the same element. Therefore, they would need to have a subscript of "2" next to their symbols.
When balancing an equation, you want the same amount and type of atoms on both sides. By adding a coefficient of "2" in front of the product, two H's and two I's are now on both sides.
Answer:
Option-D : They move freely in all directions.
Explanation:
The physical properties of gases are well explained by Kinetic Molecular Theory. The key postulates of this theory are;
1) Composition: Gases are made up of small particles called molecules. The size of these molecules is very small as compared to the distance between molecules, therefore the actual volume of molecules is taken negligible as compared to volume occupied by them.
2) Intermolecular Forces: All the gas molecules present in a container behaves independently because they have no force of interactions between them Hence, the attractive forces are taken negligible or too little.
3) Energies: Gas molecules have greater kinetic energy as compared to solids and liquids. Hence, The gas molecules move randomly. They collide with each other and with the walls of the container which causes pressure.
Conclusion:
Therefore, due to large spaces, no interactions, small sizes and high energies the gas particles move freely and there position is not stationary.

Answers are in the explanation
Explanation:
A bomb calorimeter is a <em>constant volume </em>calorimeter in which medition of change in temperature allows the medition of change in internal energy (ΔU) for chemical reactions or physical changes.
This ΔU can be converted in ΔH thus:
ΔH = ΔU + PV
That means that:
A bomb calorimeter is a piece of equipment designed to measure <em>delta H</em>
As there was said:
Reactions carried out in a bomb calorimeter occur at constant <em>volume</em>
To calculate the heat absorbed or released by a reaction carried out in a bomb calorimeter, we use the equation: <em>q = C * delta T</em>
Where C is the heat capacity of the calorimeter, delta T is the change in temperature and q is the heat produced in the chemical or physical process
I hope it helps!
