Answer:
One triple bond and four non bonding electrons
Explanation:
In considering the lewis structure of carbon monoxide, we must remember that the molecule contains a total of ten valence electrons. Four are the valence electrons that are present on the valence shell of carbon while six are the valence electrons on oxygen. Some of these valence electrons participate in bonding in the CO molecule.
Out of the six valence electrons on oxygen, two valence electrons participate in bonding with carbon while the other four electrons remain localized on the oxygen atom as two lone pairs of electrons.
Hence there are four nonbonding electrons in the lewis structure of CO as well as one triple bond.
The molar mass of monotonic Nitrogen is 14 g/mol. Since this is diatomic Nitrogen, double that to 28 g/mol.
Next, divide total mass by molar mass, 500 g / 28 g/mol, which gives <span>17.8571 moles. A mole is defined as being 6.022*10^23 molecules, so multiply moles by molecules/mol (Avogadro's number), and we finally end up with something like 1.075 * 10^25, give or take a few billion particles.</span>
7.93 x 10⁶mi
Explanation:
Significant figures are numbers that shows how accurate and precise scientific measurements are reported.
Here are some rules to identifying them;
- All non-zero digits are significant
- zeros between digits are significant
- leading zero before a decimal are not significant
- trailing zero after a decimal are significant
- trailing zero before a decimal point are significant.
The number 7926381 has 7 significant numbers.
To write in the scientific notation, we simply express as N x 10ᵃ
N is the number of significant number
a is the exponent
N here is 7.93
a here is 6
7.93 x 10⁶mi
