Answer: Concentration of are equal in pure water.
Explanation:
Also, pure water has neutral with 7 pH value ,
So, the of pure water is given
Hence, Concentration of are equal in pure water
Explanation:
<u>The point of difference between metals and non metals are as follows - </u>
Metals -
Metals are malleable in nature , so can be beaten into thin sheets .
Non - metals -
Non - metals are brittle in nature , so when beaten , it can be powdered .
Metals -
Metals have one to three electrons in the very outer most shell .
Non - metals -
Non - metals have four to eight electrons in the very outer most shell .
Metals -
Metals are lustrous in appearance .
Non - metals -
Non - metals re not lustrous in appearance .
Dissolving 0.729 mol NaCl in 2530 mL of water yields a solution with 2.88M concentration.
Explanation:
The moles of NaCl given will be dissolved and volume will be made with given data will give molarity.
The units for molarity are moles/litre, so the volume given in ml will be converted to litres by dividing it with 1000.
data given:
number of moles of NaCl = 0.729 moles
volume of the solution = 2530 ml or 2.53 litre
To calculate the concentration of the solution the formula used is:
molarity =
= 0.288 M
The concentration or molarity of the solution OF NaCl is 2.88M
1.2*104 is 12000 it is easy just try ur best
The results of this experiment gave Rutherford the means to arrive at two conclusions: one<span>, an atom was much more than just empty space and scattered electrons and </span>two<span>, an atom must have a positively charged center that contains most of its mass (which Rutherford termed as the </span>nucleus<span>).
