276mph that is easy because you times 11.5 with 24 which is the total number of hours per day
Answer:
The cell division in which number of chromosome remain same is mitosis and in it is reduced to half is mieosis.
Explanation:
Answer:
the density of the sample - the melting point of the sample
Explanation:
Intrinsic property is the property of matter which exists itself or within subject. In other words, it do not depend on the mass of the sample. An extrinsic property is not inherent or essential to subject which is being characterized. In other words, it depend on the mass of the sample.
For example,
Density, melting point are example of intrinsic property. Whereas, weight, volume are an example of extrinsic property.
Intrinsic properties helps to determine the matter. Thus, density of sample and melting point of sample is the answer.
Answer : The correct option is, (C) Both the atomic mass and the atomic number increase from left to right.
Explanation :
The general trend of atomic number and atomic mass in the periodic table is,
Both atomic number and atomic mass increase from left to right and decreases from right to left in the periodic table due to the addition of the number of neutrons and the number of protons in the nucleus.
Hence, the correct option is, (C) Both the atomic mass and the atomic number increase from left to right.
Answer: The molar solubility of barium fluoride is 0.0183 moles/liter.
Explanation:
The equation for the reaction will be as follows:

By Stoichiometry,
1 mole of
gives 2 moles of
and 1 mole of 
Thus if solubility of
is s moles/liter, solubility of
is s moles/liter and solubility of
is 2s moles/liter
Therefore,
![K_sp=[Ba^{2+}][F^{-}]^2](https://tex.z-dn.net/?f=K_sp%3D%5BBa%5E%7B2%2B%7D%5D%5BF%5E%7B-%7D%5D%5E2)
![2.45\times 10^{-5}=[s][2s]^2](https://tex.z-dn.net/?f=2.45%5Ctimes%2010%5E%7B-5%7D%3D%5Bs%5D%5B2s%5D%5E2)



Thus the molar solubility of barium fluoride is 0.0183 moles/liter.
