how many of these elements are found in some organisms but not at all?
SIX (6)
Answer:
the mass of a tree is primary carbon
Explanation:
<u>the</u><u> the carbon comes from carbon dioxide during photosynthesis</u>
Answer:
b. Supersaturated
Question 6 says CO2, not CO.
At STP, one mole of any gas occupies 22.4 L. So, at STP, 33.6 L of our gas contains (33.6 L)/(22.4 L/mol) = 1.5 moles.
One mole of any substance contains 6.022 × 10²³ particles, or in this case, molecules. So 1.5 moles contains (1.5 moles)(6.022 × 10²³ molecules/mole) = 9.03 × 10²³ molecules.
As you can see, in this case it doesn’t matter what the identity of the gas is. But it does matter when it comes to naming. If the substance is CO, as you’ve typed, its name is carbon monoxide. If the substance is CO2 as it’s presented in the image, then its name is carbon dioxide.
Answer:
carbon atoms with the usual 6 neutrons have a mass number of 12 (6 protons + 6 neutrons = 12), so they are called carbon-12. Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13). These atoms are the isotope called carbon-13.
an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.
