Answer:
HNO3
Explanation:
Try looking up on the internet-
"Science compound creator" and plug in the compounds it gives, and it will give you a formula.
The answer is .1 kilometers because 2 times 5,000 equals 10,000 cm.
hope this helps
Answer:
Two (2) electron pairs
Explanation:
The sharing of electron pairs by atoms forms a type of bond called COVALENT bond. Atoms that form covalent bonding (share electrons) do so in order to fill their outermost electron shells, hence, gain chemical stability.
However, when two atoms like carbon share TWO PAIRS of electrons with each other, a DOUBLE BOND is formed. An example is the double bond formed in Ethylene (2HC=CH2). A total of four valence electrons (a pair from each carbon) are shared between the two carbon atoms.
The stoichiometry of the reaction is 5 mols of O2 produces 4 mols of CO2.
1 mol at STP is equivalent to 22.4 liters.
So, 5*22.4 liters of O2 produces 4*22.44 liters of CO2
Then 60 liters of O2 produces 60*4/5 = 48 liters of CO2
