Explanation:
Isotopes are elements that differ in the number in neutrons while the numner of protons are the same. The answers of the questions are: 1) 18/8 O 2) 22/10 Ne 3) 53/25 Mn 4) 37/24 Cr 5) 106/81 Ti.
Answer:
Option (4)
Explanation:
The cloud forests are located at high elevated areas in the tropical and subtropical regions. They are characterized by the presence of clouds that maintains a relatively cold environment, favoring the existence of various type of plant and animal species. The temperature is comparatively low, rich in moisture content and the amount of sunlight also is low in this region. The change in these factors can cause a decrease in the population growth in these cloud forests.
Thus, low moisture content in the atmosphere and excessive amount of sunlight in this type of forest can lead to the reduction in its population.
Hence, the correct answer is option (4).
7. Neutralisation. Which would (obviously) appear GREEN on the chart.
A nuclear reaction involves the reaction of nuclei of atoms. This can be expressed in the form of nuclear equation in which the reactant nuclei are represented by their respective symbols carrying two numbers, the mass number denoted by A present at the top left and the atomic number (Z) written at the bottom left of the symbol of the element's nucleus.
The given nuclear reaction is the fusion of two isotopes of hydrogen, H-2 to form Helium-3 nucleus:
This reaction produces a single neutron.
