Answer:

(d) 3,7-dimethyl-4-nonyne.

Explanation:

Hello,

In this case, considering the attached picture on which you can see that the main chain has nine carbon atoms, one tripe bond at the fourth carbon and two methyl radicals at the third and seventh carbons respectively, by following the IUPAC rules, the name would be: (d) 3,7-dimethyl-4-nonyne since the chain must start at the side closest to the first triple bond due to its priority and subsequently considering the present radicals.

Best regards.

Alja [10]

Answer:

C6 H10 O5+ 6O2-----> 6CO2+5H2O+heat

Explanation:

There are 6 carbon atoms in reactants to balance you put coefficient 6.

This makes the oxygen in CO2 12 so to balance put 6 in oxygen in reactants.

There are 10 hydrogen atoms in reactants to balance you put 5 in front of H2O in products.

If u recheck: 6 C atoms in reactants, 6 C atoms in products.

10 H atoms in reactants, 10 H atoms in products.

17 O atoms in reactants, 17 O atoms in products.

To break the oxygen-oxygen bonds in a single O2 molecule, 1 × 10–18 J of energy is required. Which of the following wavelengths

Sonbull [250]

E = hc/(lamda)

The lamda symbol is wavelength, which this site does not have. I can represent it with an "x" instead.

Plancks constant, h = 6.626×10^-32 J·s

Speed of light, c = 3.00×10^8 m/s

The energy must be greater than or equal to 1×10^-18 J

1×10^-18 J ≤ (6.626×10^-32 J·s)*(3.0×10^8 m/s) / x

x ≤ (6.626×10^-32 J·s)*(3.0×10^8 m/s) / (1×10^-18 J)

x ≤ 1.99×10^-7 m or 199 nm

The wavelength of light must be greater than or equal to 199 nm

PLS HELP ASAP i really need an answer a correct one

Answer: 67.23 L

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Putting in the values we get:

$\text{Number of moles of methane}=\frac{48g}{16g/mol}=3moles$

1 mole of methane occupies = 22.4 L

Thus 3 moles of methane occupy = $\frac{22.4}{1}\times 3=67.23L$

Thus volume of 48 grams of methane gas is 67.23 L
