Food chains allow energy to move through an ecosystem. For example, energy is transferred from organism to organism such as the sun gives energy to grass, grass gives energy to grasshoppers when they eat grass, mice eat grasshoppers, and snakes eat mice, eagles or bigger birds of prey eat snakes. A technique discovered by Charles Elton named energy pyramids display how energy is dispersed on a pyramid starting from producers to tertiary consumers. An example of a producer would be grass, primary consumer would be a grasshopper (herbivores), a secondary consumer would be a mouse/mice (eat herbivores), and a tertiary consumer (eat secondary consumers) would be an owl. Starting from the bottom of the energy pyramid (producers) to the top (tertiary consumers) it 10% of energy is available to travel up the pyramid. That is your scientific explanation!
Answer:
Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.
Explanation:
:)
For group 16 elements, the atomic radii increases down the group as a shell of electron is added on each time.
0.0001 is the objects mass because you go from mili, to centi, deci, gram, deca, hecta, Kila. that's 6 decimal points which is what times you 3 zeroes before the 1. The decimal point started out at the end of 100 and moved 6 places to be 0.0001
Reaction is NaHCO3 + HCL = H2CO3 + NaCl
the ratios are 1:1
the 8 moles of HCl are in excess
so if you use 4 moles of NaHCO3 then you will obtain 4 moles of carbonic acid
hope that helps
