Answer:
Explanation:
Hello,
In this case, by knowing that the used NaOH equals in moles the acid (monoprotic) as shown below, during the titration:
By knowing the volume and the concentration of the NaOH, one obtains:
Thus, the molar mass of the acid is computed based on the previously computed moles and the given mass as follows:
Best regards.
Explanation:
The relative formula mass of a substance, shown in grams, is called one mole of that substance. So one mole of carbon monoxide has a mass of 28 g, and one mole of sodium oxide has a mass of 62 g
Answer:
Option (C)
Explanation:
In the field of astronomy, the redshift is defined as the shifting of the wavelength of light towards the red color of the spectrum. It describes about how the universe is expanding in every direction. The scientists have observed that the light in the universe emitted from distant objects such as the stars and galaxies is redshifted. This provides an example of Doppler's effect that is generally defined as the change in the wavelength of a wave that occurs when an observer moves relative to the source of the wave.
Hence, the correct answer is option (C).
The volume of the substance is 61.4 litres.
Explanation:
Specific density is the ratio of density of a substance at a given temperature with the density of reference substance.
Data given:
mass = 750 grams
specific gravity = 12.2
volume=?
The formula to be used:
Specific gravity =
suppose the other substance is water so its density is 1g/ml at 4 degrees
Putting the values to the equation:
density of the object = 1 x12.2
density of the substance = 12.2
Now using the formula:
density =
putting the values in the equation:
volume =
= 61.4ml is the volume of the substance.
Answer: sphere interaction
The ocean absorbing excess carbon dioxide from the atmosphere in order to maintain balance is an example of sphere interaction. The different spheres like lithosphere, hydrosphere, atmosphere, and geosphere interact with one another naturally to achieve equilibrium in the environment.
