Answer:
B. it is used to open and close the circuit
Answer:
The ratio of solution 1 to solution 2 is 24.20 to 100.00.
Explanation:
We will mix V₁ (L) of solution 1 with V₂ (L) of solution 2 to get the final solution.
So the mole concentration in the final solution is calculated as below, note that C₁ is the concentration of solution 1, and C₂ is the concentration of solution 2
![[M] = \frac{V_{1} C_{1} +V_{2}C_{2}}{V_{1}+V_{2}} = \frac{4 V_{1} + 0.1 V_{2}}_{V_{1}+V_{2}}}=0.86](https://tex.z-dn.net/?f=%5BM%5D%20%3D%20%5Cfrac%7BV_%7B1%7D%20C_%7B1%7D%20%2BV_%7B2%7DC_%7B2%7D%7D%7BV_%7B1%7D%2BV_%7B2%7D%7D%20%3D%20%5Cfrac%7B4%20V_%7B1%7D%20%2B%200.1%20V_%7B2%7D%7D_%7BV_%7B1%7D%2BV_%7B2%7D%7D%7D%3D0.86)
Then we can calculate for the ratio

Answer: SOLID WATER(ICE) IS LESS DENSE THAN LIQUID WATER
Explanation:Water molecules are bonded together by Hydrogen bonds, Hydrogen bonds are intermolecular forces binding the molecules of Oxygen with that of Hydrogen. When in an ICE state,the solid form of water will float on the liquid form of water, because the orientation of Hydrogen bonds pushes or makes the Ice molecules to stay far apart from each making it less Dense than liquid water.
Here is the correct answer of the given question above. The principal reason that we must consider the uncertainty principle when discussing electrons and other subatomic particles, but not when discussing our macroscopic world is that photons of only certain allowed frequencies can be absorbed
or emitted as the electron changes energy state. Hope this answer helps.
We will get Plagioclase as phenocryst in a porphyritic basalt using Bowmen's reaction series.
Porphyritic basalt is mafic i.e. it has low silica content and have higher melting point than felsic which have higher silica content . Porphyritic basalt's mineral composition is Calcium Plagioclase . Phenocryst is large crystal , early forming igneous rock.
Thus , on cooling plagioclase will be seen as phenocryst which is clear from Bowmen's reaction series because it is present on right side of series at higher temperature range in continuous branch in mafic region.
