A catalyst "provides an alternate reaction pathway with a lower activation energy". (2) is the correct answer.

Activation energy is the energy needed to conduct a chemical reaction. When a catalyst is put into the system, it makes the system require less activation energy, making the reaction go faster.

Hope this is helpful~

What type of ions do metals naturally form? Negative ions, by gaining electrons to fill the valence shell Negative ions, by losi
Mila [183]

Answer: Option (d) is the correct answer.

Explanation:

Metals are the species which contain more number of electrons.

When a specie loses electrons then it acquires a positive charge. Whereas when an atom gains electrons then it acquires a negative charge.

Thus, as metals have more number of electrons, therefore, in order to gain stability metals readily lose electrons.

Hence, metals naturally form positive ions, by losing electrons to empty the valence shell.

How many stereoisomers are possible for 1 2-dichlorocyclopentane?
slega [8]
<span>There are only three stereoisomers of 1,2-dimethylcyclopentane. As there are only two chiral carbons, so the maximum number of stereoisomers is 4, but two are the same meso-compound which means that there are only 3.</span>

A total of 5 mol iron oxide has a mass of (798.5g)
Anit [1.1K]

Answer:

Yes , 5 mole of Iron Oxide has mass of  798.5 g

Explanation:

Formula of iron oxide:

Fe_{2}O_{3}

Atomic mass of Fe = 55.84 amu

Atomic mass of O = 15.99 amu

Molar mass of Fe2O3 = 2(atomic mass of Fe) + 3(atomic mass of O)

= 2(55.84) + 3(15.99)

=111.68 + 47.97

= 159.69 g/mol

<u>Molar mass</u> always equal to <u>1 mole</u> of the substance.

1 mole = 159.69 g

5 mole =

=5\times159.69

= 798.45 g
