Answer: B
CH4 + 2 O2 -> CO2 + 2 H2O
Answer:
A mixture
Explanation:
The substance whose magnetic properties is tested is mixture of many compounds, elements or molecules.
A mixture has the following properties:
- Their composition is indefinite
- Their constituents retain their identity
- Constituents react differently to changed conditions
- Their constituent can easily be separated by physical procedures.
Since a part of the mixture responds differently to magnetism, we can say, the other part is made up of a different set of compound.
Answer:
0.174 M
Explanation:
The same can be solve by using Nernst's equation
The Nernst's equation is:
![Ecell=E^{0}_{cell}-\frac{0.0592}{n}log\frac{[anodic]}{[cathodic]}](https://tex.z-dn.net/?f=Ecell%3DE%5E%7B0%7D_%7Bcell%7D-%5Cfrac%7B0.0592%7D%7Bn%7Dlog%5Cfrac%7B%5Banodic%5D%7D%7B%5Bcathodic%5D%7D)
For silver cell
n= 1
As both the compartments have silver nitrate solution,t the standard emf of cell will be zero.
Given
Ecell = 0.045
[Anodic compartment]= 1 M
Putting values
Taking antilog and solving
[AgNO3]=0.174 M
Answer:
these micronutrients are not produced in our bodies and must be derived from the food we eat.
Explanation:
Vitamins and minerals are micronutrients required by the body to carry out a range of normal functions. However, these micronutrients are not produced in our bodies and must be derived from the food we eat. Vitamins are organic substances that are generally classified as either fat soluble or water soluble.
