Which statement explains why catalysts are important for living

Chemistry
1 answer:
Marina86 [1]3 years ago
8 0

Answer:

Catalysts allow chemical reactions to occur at temperatures at which the organism lives.

Explanation:

Catalysts are molecules that speeden the rate of chemical reaction by lowering the activation energy of the reaction. In a living system, the catalyst are ENZYMES, which help to hasten up many biochemical reactions.

Another function of catalyst in living systems is that it allows chemical reactions to occur at temperatures at which the organism lives.

A total of 1 mol iron oxide has a mass of
o-na [289]
<h3><u>Answer;</u></h3>

160 g

<h3><u>Explanation;</u></h3>

1 mole of a compound contains a mass equivalent to the relative formula mass of that particular compound.

the formula of iron oxide is Fe2O3

R.A.M of Iron = 56 , while that of oxygen is 16

RFM = (56 ×2) + (16 ×3)

       = 112 + 48

       = 160

Therefore, 1 mole of Iron oxide contains 160 g

RideAnS [48]

Answer:

Ionic or Electrovalent Bond.

Explanation:

its ionic bond because the Halogen atom (F) is getting bigger with electrons. This increases the size of the dipoles which cause van der waals dispersion forces. Hence resulting to increase in the strenght of the bond.

where 1s, 2s, and 2p are the occupied subshells, and the superscript "2" is the number of electrons in each of these subshells.
SOVA2 [1]

Answer: 1s^22s^22p^63s^23p^64s^2

Explanation:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The electrons are filled according to Afbau's rule in order of increasing energies where orbital with higher value of (n+l) has higher energy as compared to orbital having lower (n+l) value. Thus the electronic configuration for calcium with atomic number of 20 and hence containing 20 electrons is :

Ca:20:1s^22s^22p^63s^23p^64s^2
