The action or power of focusing one's attention or mental effort.
a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction.
a substance that slows down or prevents a particular chemical reaction or other process, or that reduces the activity of a particular reactant, catalyst, or enzyme.
Answer: the correct answer is C velocity.
Explanation: I just got the answer wrong on the exam.
Answer:
1. Dynamic equilibrium is a equilibrium in which the rate of forward direction is equal to the rate of backward direction. It is represented by a right left arrow.
2) Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For the given chemical reaction:
The expression for
is written as:
![K_c=\frac{[[Fe(SCN)]^{2-}]}{[Fe^{3+}][SCN^-]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5B%5BFe%28SCN%29%5D%5E%7B2-%7D%5D%7D%7B%5BFe%5E%7B3%2B%7D%5D%5BSCN%5E-%5D%7D)
3) The value of
is 1000 , which means the products are more favoured as compared to reactants and that the equilibrium lies more towards product side.
A sodium ion has a charge of +1
A chlorine ion has a charge of -1
These ions are bonded by electrostatic forces, by the principles rule that all opposites attract. So it looks like a one Na atom bonded to one Cl atom. Like a double scoop ice cream that's not stacked
Answer:
False
Explanation:
A significant number is a number that is used to express the accuracy in a measurement. There are some rules that binds the identification of significant figures when reporting a scientific measurement.
- All non-zero numbers are significant
- Zeros in between two digits are significant.
- Zeros to the right of the decimal are significant.
- Leading zeros are just place holders and are not significant.
- Trailing zero in a whole number with decimal is significant
- Trailing zero without a decimal is not significant.

We can see that not all zeros in a measurement is significant. For example, 540 has 2 significant numbers because the zero is not significant but 540.2 has 4 significant numbers.
