Answer:
The speed at which the reactants change to products over a given time.
Explanation:
A chemical's <u>reaction rate</u><u> is the change in the concentration of a reactant or a product with time (in moles per second)</u>.
Remember that during a chemical reaction, reactants are converted to products. Or what is the same, products are formed at the expense of reactants. This can be represented:
reactants → products
Therefore,<u> the progress of a reaction can be followed measuring the decrease in concentration of the reactants or the increase in concentration of the products.</u>
According to the temperature and other parameters, the reaction rate can increase or decrease.
Answer:
Perma Dorji (PD) and Kesan Choden (KC) are children.
If the number of brother PD has is X, the number of sisters she has is 3X
If the number of brothers KC has is 3X, then the number of sisters she has is 3X-2
Explanation:
The total number of children (brothers and sisters) therefore are:
PDs siblings = 3X+X plus
KCs siblings = 3X2
= 3X+X +3X-2
=6x-2
Let's assume that X is 1, therefore the number of siblings equals
6(1)-2
= 4
Don't forget the PD and KC are also children.
Therefore, the total children in the family is equals to 6

Probably America though.
<span>Let me explain it a little better. During primary succession, the pioneer species determine what other kinds of organisms will settle there.I think this is better explained. Hope you like it</span>
