Answer:
See explanation
Explanation:
Matter may exist in three phases; solid, liquid and gas. The state in which matter exists depends on the extent of intermolecular forces operating in the substance.
In solid particles, the molecules that compose the solid are close together because the molecules of a solid do not move from place to place but they continue to vibrate about their fixed position.
For liquids, the molecules that compose a liquid are in random motion but are less energetic than molecules of a gas.
In gases, the molecules are not held together at all. The molecules of a gas have the highest degree of freedom. They move from one point another at a high velocity.
Hence, the order of increasing degree of movement of the particles in different states of matter = solids<liquids< gases.
Solids have well arranged particles, the molecules of a liquid are a little more disorderly than liquid particles while gas particles are the most disorderly of all the states of matter.
Answer : The mass of oxygen will be, 36.8 grams
Solution : Given,
Moles of water = 2.30 moles
Molar mass of
= 32 g/mole
First we have to calculate the moles of oxygen.
The balanced chemical reaction will be,

From the balanced reaction we conclude that
2 moles of water decomposes to give 1 mole of 
2.30 moles of water decomposes to give
moles of 
Now we have to calculate the mass of oxygen.


Therefore, the mass of oxygen will be, 36.8 grams
It is B. One single bond and one triple bond.
Answer:
Explanation:
The concept applied is the conductivity as it relates to the dissociation and the number of ions in solution. BaCl2 and KBr are ionic solids that will dissociate completely in water to give trivalent and divalent ions respectively.
Benzoic acid on the other hand is a weak acid as such it will not dissociate in water. sugar is a covalent compound.
Hence BaCl2 will have the highest conductivity based on the aforementioned reasons, then followed by KBr ; BaCl2 > KBr > C6H5COOH > C6H12O6
