<u>Answer:</u> The molarity of calcium hydroxide in the solution is 0.1 M
<u>Explanation:</u>
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is 
We are given:
Putting values in above equation, we get:
Hence, the molarity of in the solution is 0.1 M.
Answer: Low melting points
Explanation:
Answer the correct option will be option B.
Explanation: this is how he showed the electron could orbit the nucleus without falling into it. This is so because he explained that the electron revolves around the nucleus in a fixed circular orbit with fixed energy and cannot occupy just any energy level which is defined as quantisation of energy.
option A is one of postulates given by Dalton in his Dalton's atomic theory which later proved to be wrong.
option C it is one of the postulates given by the in J.J Thomson in his model of an atom which was the first atomic model.
option D Schrodinger has used the wave nature to explain the position of electrons around the nucleus.
Explanation:
We're using the chemical equation:
4P + 5O2 → P4O10
First convert grams of product to moles:
75g P4O10 x (1mol / 284 g) = 0.264 mol P4O10
Using the mole ratios, convert moles of product into moles of reactant needed:
0.264 mol P4O10 x (5 mol P / 1 mol P4O10) = 1.32 mol O2
Gasses are easy to compress
And they expand to fill their containers
