Matter is made up of particles too small to be seen with the naked eye called atoms
MArishka [77]3 years ago
4 0

Explanation:

Any substance which occupies some space and has some mass is known as matter.

Every matter is made up of tiny particles which are known as atoms. Any matter can either have same atoms or with different atoms.  

Thus, we can conclude that matter is made up of tiny particles that are too small to be seen with the naked eye. These tiny particles are known as atoms.

Calculate the ph of the solution made by adding 0.50 mol of hobr and 0.30 mol of kobr to 1.00 l of water. the value of ka for ho
nikdorinn [45]
To fully understand the problem, we use the ICE table to identify the concentration of the species. We calculate as follows:

Ka = 2.0 x 10^-9 = [H+][OBr-] / [HOBr] 

HOBr  = 0.50 M 
KOBr  = 0.30 M = OBr-

<span>     HOBr + H2O <-> H+ + OBr- </span>
<span>I     0.50        -              0          0.30 </span>
<span>C       -x                        x             x 
</span>---------------------------------------------
<span>E(0.50-x)                    x       (0.30+x) </span>

<span>Assuming that the value of  x is small as compared to 0.30 and 0.50 </span>

<span>Ka = 2.0 x 10^-9 = x (0.30) / 0.50) </span>

<span>x = 3.33 x 10^-9 = H+</span>

Define alkylenes and alkanes​
lawyer [7]

Answer:

Alkylenes: any of the series of unsaturated hydrocarbons containing a triple bond, including acetylene.

alkanes​: Alkanes are organic compounds that consist entirely of single-bonded carbon and hydrogen atoms and lack any other functional groups. Alkanes have the general formula CnH2n+2 and can be subdivided into the following three groups: the linear straight-chain alkanes, branched alkanes, and cycloalkanes.
