Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO 3) than the organic is a sedimentary rock composed largely of the minerals calcite and araganite.
You can determine an element based on its protons due to the atomic number.
Atomic number is the number of protons in an atom and you can locate it on your periodic table as the number above the letter. Each element has a different number of protons and because of that you can find the element on the periodic table based on its atomic number.
Answer:
The steps that must be long to obtain separately the components (to the substances) of a mixture of water, salt and sand, are respectively: A) filtration and siphoning B) decanting and siphoning C) simple filtration and distillation D) collection and decantation.
Simple filtration and Siphoning is the method. When an insoluble solid is present in a liquid. Filtration is the ideal method of separation,The sand is filtered by the filtered paper as water is allowed to pass through the filter paper into a beaker where the funnel which hold the filter paper emptied into.
Water molecules is Siphoned, pull by force of gravity through the sand, past the filter paper to emerge as clean in the beaker below.
Answer:
C Metals are ductile, meaning they can be pulled into wires.
<u>Answer:</u> The number of atoms of carbon present in given number of moles are 
<u>Explanation:</u>
We are given:
Number of moles of carbon = 
According to mole concept:
1 mole of an element contains
number of atoms.
So,
of carbon will contain =
number of atoms.
Hence, the number of atoms of carbon present in given number of moles are
