Answer:
Number of protons and electrons stay constant
Number of neutrons Differs
Explanation:
Isotopes are the different kinds of same element. Now, as we know quite well that an element can only have one atomic number, this means that the proton number is irrespective of the type of atom
Of the element. The proton number is the identity of the element.
As we know that the atom is electrically neutral, it means the number of electrons will always stay the same too.
Since isotopes are not alike in every respect, the number of neutrons differ. This means they have same atomic numbers but different mass numbers.
The correct answer is A. PH value
If a substance is very acidity it has a high PH, if it is less acidic (alkalinity) is has a lower PH. For instance, water has a PH of 7 because it is in between of being acidic and alkaline.
Acetylene appear as gas and is unstable and thus kept in presence of other solution such as liquid ammonia.
Ethanol on reacting with ammonia produces ethylamine as follows:
Ethanol again on reacting with ethylamine produces diethylamine and triethylamine as follows:
The reaction between sulfuric acid, H2SO4 , and the base sodium hydroxide, NaOH , is a neutralization reaction. Na2SO4 is the salt sodium sulfate. ... For example, the reaction you've chosen is an acid-base reaction (also known as a neutralization reaction).
