I believe the answer is B, as they only solely survive on tough and fibrous plant matter. Plants are producers because they can produce their own food instead of consuming something else to survive.
Gases has highest Kinetic energy as kinetic energy is the movement of molecules between the intermolecular spaces.
Please please try to answer my question as I am a forgeiner from India
Hello!
A reaction where the products have less chemical potential energy than the reactants had originally is called an exothermic reaction. Although the scientist didn't observe light or sound, an observation that would support her prediction is the rise in temperature after the reaction has completed. Exothermic reactions release energy in the form of heat, and the temperature would rise in an exothermic reaction.
Have a nice day!
Lead is a basic metal and almost 11 isotopes of Lead are reported. The isotopes with greater natural abundance are as follow;
1) ²⁰⁸Pb with abundance 52.4 %
2) ²⁰⁶Pb with abundance 24.1 %
3) ²⁰⁷Pb with abundance 22.1 %
4) ²⁰⁴Pb with abundance 1.4 %
Molar mass of ²⁰⁸Pb:
Molar mass of any element is the total of number of protons, neutrons and electrons.
As, number of protons in Lead are 82 then in ²⁰⁸Pb isotope number of neutrons are...
# of Neutrons = M.mass - # of protons
# of Neutrons = 208 - 82
# of Neutrons = 126
Result:
Molecular Mass of Lead (²⁰⁸Pb) is 208 amu.
# of Protons in ²⁰⁸Pb = 82
# of Neutrons in ²⁰⁸Pb = 126
