Answer:
Answer in explanation
Explanation:
In the first case, we divide each of the masses by the respective atomic masses:
N =0.615/14 = 0.043928571428571
O = 0.703/16 = 0.0439375
It can be seen here that the values are similar, hence the formula is NO
now let us look at the second data set:
N = 1.27/14 = 0.090714285714286
O = 2.9/16 = 0.18125
We now divide by the smallest
N = 090714285714286/090714285714286 = 1
O = 0.18125/090714285714286 = 2
The formula here is thus NO2.
It can be seen that there are different oxides of nitrogen here which clearly indicates the law of multiple proportion.
Option A. Health claim
Health claim must be supported by scientifically valid evidence to be approved in using for food label.
This is also a food guide to all consumers the food content implied by manufacturers to their products.
Alkali metals impart characteristic colours to the flame due to low ionisation enthalpy, when an alkali metal or its salt is heated in a flame, the valence electrons are excited to higher energy level.
An igneous rock is defined by how the rock is formed; igneous rocks are formed by the solidification of molten rock materials. Examples of igneous rocks include Diorite, Gabbro, Granite, Pegmatite.
