The answer is; C

There are 2 Carbons, 4 Hydrogens, and 6 oxygens  on both sides

All the moles of the elements on the right of the reaction equation are balanced with those on the left of the equation. These moles are indicated by the number in front  of the symbols of the elements. This ensures that the first law of thermodynamics is observed. This law states that no matter or energy can be destroyed or created; It can only be transformed.

There are five states of matter out of which we encounter three states of matter in our day today life

a) gas b) solid and c) liquid

the main difference between the three is of

a) Inter molecular forces of attraction

b) thermal energy

due to this

a) solid has high intermolecular forces and low thermal energy: thus they have fix shape and occupy fix volume

b) liquid has intermediate forces and medium themal energy. Thus they may have fixed volume and but no fix shape

c) gas has weak intermoelcular forces and high thermal energy. thus they have no fixed volume no fix shape

so in the given problem

the state of the substance D- Gas.

Which compound reacts with an acid to produce water and a salt
Hatshy [7]
I'm not exactly sure which one but I do know that an acid and a base react in a aqueous solution to form water, so i would probably eliminate the ones that aren't aqueous solutions.

What is the single factor that classifies an element as a transition metal?
klasskru [66]
The answer is b) the highest occupied orbital is a “d”orbital.
Transition metals are metals where the highest energy electrons partially fill the d subshells. There are some elements with complete d subshells but on forming cations they have incomplete d subshells.
These transition metals have some properties that are different from the other metals .
