Answer:
Boiled a added acidic solution for Lowe's home improvement for car insurance cost the Africa map of the soul
Answer:
Ca
2+
<K + <Ar<Cl − <S 2−
Explanation:
Ar,K +
,Cl −
,S 2−
,Ca 2+
have the same number of electrons. Their radii would be different because of their different nuclear charges. The cation with the greater positive charge will have a smaller radius because of the greater attraction of the electrons to the nucleus. Anion with the greater negative charge will have the larger radius. In this case, the net repulsion of the electrons will outweigh the nuclear charge and the ion will expand in size. Hence the correct order will be Ca
2+ <K + <Ar<Cl − <S 2−
Methane CH4
ethane C2H6
propane C3H8

pentane C5H12
Answer:
true
Explanation:
Materials science is an interdisciplinary field involving the properties of matter and its applications to various areas of science and engineering. It includes elements of applied physics and chemistry, as well as chemical, mechanical, civil and electrical engineering.
and we all know matter involve solid liquid or gas
Answer:
Explanation has been given below.
Explanation:
- A buffer consists of either of a weak acid along with it's conjugate base or a weak base along with it's conjugate acid.
- Let's consider a buffer consists of a weak acid along with it's conjugate base
- If we add an acid to this buffer then conjugate base gets protonated and converted to corresponding weak acid. So effect of addition of acid gets neutralized by forming weak acid rather than increase in concentration of proton in solution.
- If we add a base to this buffer then weak acid gets converted to corresponding conjugate base. So effect of addition of base gets neutralized by forming conjugate base rather than in crease in concentration of hydroxyl ion in solution.
