Answer:
Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
i hope this helps!
The answer is (2) 1.0 dm3. In a balanced equation, the ratio of the mole number of the compounds is equal to the coefficients. And the ratio of volume of gas is equal to the mole number under same condition. So the answer is 1.0 mol.
Answer:
NaNH2, NH3
Explanation:
Choose the most appropriate reagent(s) for the conversion of propyne and 2-methyl-1-tosyloxy propane to 5-methyl-2-hexyne. NaNH2, NH3 NaOH, H2O KOCH2CH3, HOCH2CH3 H2SO4 NH3
answer is NaNH2, NH3
NaNH2, NH3 is strong to to convert propyne into a nucleophilic salt which in turn displaced tosylate in 2-methyl-1-tosyloxy propane to yield 5-methyl-2-hexyne.
Propyne and 5-methyl-2-hexyne. are still of the same homologous series,, so no triple bond is broken during the reaction
The essence of a reagent is to bring the reaction to its end point
