Ok, so... 20.219 grams is the mass of the flask with the water in it.
10.267 grams is the mass of only the flask. Subtract them to find the water mass.
20.219 g (flask+water) - 10.267 g (flask) = 9.952 g (water)
Answer:
B)
Explanation:
In beta decay the nucleus loses a neutron and gains a proton. The mass therefore remains constant but the atomic number increases by one.
Answer:
It is called Asterism.
Explanation:
It is Asterism because Asterism refers to a pattern of stars that are seen in night sky and are very distinctive and identifiable. These group of starts have patterns. It visually seen collection of stars and it's indicate their properties and the lines that connect the stars together. It actually range from small shapes of stars to more complex stars that cover segment of the sky. The stars may be bright naked or have similar brightness.
2-bromo-3,4-dimethylpentane is combined with t-butoxide. The product of this reaction is 3,4 dimethyl - 1- pentene.
The reaction of 2-bromo-3,4-dimethylpentane is combined with t-butoxide forms 2 alkene in the elimination reaction due to steric hindrance. The least stable alkene 3,4 dimethyl - 1- pentene is easy to make. the t-butoxide is (CH₃)₃CO⁻. The reaction involves in this reaction is E2 elimination reaction. This reaction involves the one step reaction. The product will also form that is 3,4 dimethyl - 2 - pentene. so the reaction involve Elimination reaction and the product due to steric hindrance is 3,4 dimethyl - 1- pentene
Thus, 2-bromo-3,4-dimethylpentane is combined with t-butoxide. The product of this reaction is 3,4 dimethyl - 1- pentene.
