a) Carbon and oxygen are chemically bonded in carbon dioxide.
The elements lose their individual identities in CO₂, and they always combine o the proportion C:O = 1:2.
You cannot separate the elements from each other by physical means.
<h2><u>
Properties of Water Essential to Life</u></h2>
<u></u>
- Water is known to be the universal solvent because of <u>its ability to dissolve more particles</u> than any other liquid.
- Cohesion is the <u>property of water to attract other molecules</u>. This helps in making solutions that are essential for most life to propagate.

Answer: The rate will increase by a factor of 9.
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
Given: Order with respect to = 2
Order with respect to = 1
Thus rate law is:
k= rate constant
It is given that the initial concentration of NO is tripled while all other factors stayed the same
Thus the rate will increase by a factor of 9.
Answer:
Evaporation is an important process in the water cycle. If there is no evaporation, there is no moisture in the atmosphere. As a result, clouds cannot form and there is no rain. Plants do not receive natural water and die. And there would be no rivers or lakes because their water comes from evaporation via rain or snow.
Explanation:
Which list of elements contains a metal, a metalloid, and a nonmetal?(1) Zn, Ga, Ge (3) Cd, Sb, I(2) Si, Ge, Sn (4) F, Cl, Br
Sladkaya [172]
3) Cd . Sb . I
<span>look at the periodic chart- if the element is on the right it is a nonmetal, if it is on the left its a metal, and if it is in between it is a metalloid</span>
