Explanation:
Permanganate is general name for the chemical compound which containes manganate (VII) ion. Permanganate(VII) ion is strong oxidizing agent as manganese is in +7 oxidation state and can be easily reduced and oxidize others.
The balanced half reaction for reduction of the permanganate ion, 
to manganese ion, 
is shown below:
Answer: question 2 is (a) (25+273)k=298k(b) (373+273)k=646k
question 5 is 25 degree Celsius
question 1 is
a = (293-273) =20 degree Celsius
b = (470-273)=197 degree Celsius
question 3 is
a = naphthalene ball undergo sublimation due to which it convert directly into vapour and disappear into air without leaving any solid
b = the participle of perfume diffuse rapidly into air and its smell can be felt while sitting serval metre away
question 4 isthe force of allraction between the particles increases as we go from liquid to gas so the required order is : Oxygen< water< sugar
I hope it is helpful to you
Answer:
17.5% es la transmitancia de la solución problema
Explanation:
Basados en la ley de Beer que dice que:
La transmitancia de una solución es inversamente proporcional a su concentración.
Podemos hallar la transmitancia de una concentración problema sabiendo la concentración de una solución y su transmitancia:
Si una solución 0.0150M tiene una transmitancia de 35%
Y ahora la solución duplica su concentración, su transmitancia se disminuirá en la mitad, esto es:
35% / 2 =
<h3>17.5% es la transmitancia de la solución problema</h3>
Answer:
14-6
8
so 8 is the answer because atomic number is number of protons and atomic mass is sum of protons and neutrons so to find the number of neutrons we will subtract proton number with the atomic mass.
