<h2>Answer : Option D) Heterogeneous mixture</h2><h3>Explanation : </h3>
A mixture in which particles are not evenly distributed and particles keep their unique properties are called as heterogeneous mixture.
Usually, in heterogeneous mixture the substances are not evenly distributed and they can be easily separated through any physical methods. Also the components retains their original/unique properties in the mixture. It usually contains various particles from different substances that are not uniformly distributed throughout the mixture.
Metals=Reactivity increases as we move through the elements in the period table from top to bottom, and left to right. Nonmetals=Reactivity increases as we move through the elements in the periodic table, as we move from bottom to the top, and right to left. Since reactivity of nonmetals increases going up the periodic table, oxygen is therefore the most reactive nonmetal in the group. So, the answer is oxygen
Answer:
when sodium reacts with chlorine atoms, sodium will give an electron which is negative charged to chlorine.it makes sodium(+) and chlorine (-)..then sodium will attract chlorine to form sodium chloride(NaCl)
A gas is assumed to behave ideally if it follows the following assumptions:
Gas particles are very tiny so their volume is negligible. So they are considered that do not have a volume.Gas particles move at a constant motion, which means that they do not collide.Gas particles do not interact with each other, therefore, there will be no attraction or repulsion between each other.These are the main points of difference between an ideal gas and a real gas.
For a real gas, all these points are not valid, therefore:
Gas particles occupy a space and therefore have a volume.Gas particles collide with each other and their motion tends to speed up or slow down.Gas particles interact with each other.
