DNA and chromosomes can be considered related because chromosomes carry genes which in turn affect your DNA

Realice las siguientes conversiones: a) 72°F a °C, b) 213.8°C a °F, c)180°C a K, d) 315K a °F, e) 1750°F a K, f) 0K a °F.

bonufazy [111]

Answer:

a) 72 °F= 22.22 °C

b) 213.8 °C= 416.84°F

c) 180 °C= 453.15 °K

d) 315 °K= 107.33 °F

e) 1750 °F= 1227.594 °K

f) 0 °K= -459.67 °F

Explanation:

Para realizar el intercambio de unidades debes tener en cuenta las siguientes conversiones:

Fahrenheit a Celsius: $C=\frac{F-32}{1.8}$

Celsius a Fahrenheit: °F= °C*1.8 + 32
Celsius a Kelvin: °K= °C + 273.15
Kelvin a Fahrenheit: F= (K -273.15)*1.8 + 32
Fahrenheit a Kelvin: $K=\frac{F-32}{1.8} + 273.15$

Entonces se obtiene:

a) 72 °F= $\frac{72-32}{1.8}$ =22.22 °C

b) 213.8 °C= 213.8*1.8 + 32= 416.84°F

c) 180 °C= 180°C + 273.15= 453.15 °K

d) 315 °K= (315 -273.15)*1.8 + 32= 107.33 °F

e) 1750 °F= $\frac{1750-32}{1.8} + 273.15$ = 1227.594 °K

f) 0 °K= (0 -273.15)*1.8 + 32= -459.67 °F

The anion O3− does not obey the octet rule. Draw its Lewis structure and state the type of octet-rule exception. Indicate the va

Tju [1.3M]

One of the oxygen atoms in the anion O3− is hypervalent and the formal charge on this oxygen atom is -1.

Ozone is a triatomic molecule. The anion formed from ozone is called the ozonide anion. This anion is also triatomic. The resonance structures of the ozonide anion are shown in the image attached to this answer.

We can see that one of the oxygen atoms in the ozonide ion is hypervalent because it contains ten instead of eight electrons. This hypervalent oxygen atom has a formal charge of -1 while the two other oxygen atoms has a formal charge of zero.

How many molecules of sodium oxide will be created if 275 grams of sodium reacts with excess oxygen?

DaniilM [7]

Answer:

1.34 × 10²⁴ molecules

Explanation:

To calculate the number of molecules of sodium oxide that will be created if 275 grams of sodium reacts with excess oxygen, use the chemical equation to calculate the number of moles and then multiply by Avogadro's number.

1) Balanced chemical equation (given):

4Na + O₂ → 2Na₂O

2) Mole ratio:

4 mol Na : 2 mol Na₂O

3) Calculate the number of moles in 275 g of Na:

n = mass in grams / molar mass
mass of Na = 275 g
molar mass of Na₂O = 61.9789 g/mol

n = 275 g / 61.9789 g/mol = 4.437 mol of Na

4) Set a proportion to find the number of moles of product (Na₂O):

2 mol Na₂O / 4 mol Na = x / 4.437 mol Na

x = 4.437 / 2 mol Na₂O = 2.2185 mol Na₂O

5) Convert the number of moles to number of molecules:

# molecules = n × 6.022 × 10²³ molecules/mol = 2.2185 mol × 6.022 × 10²³ molecules/mol = 1.34 × 10²⁴ molecules (rounded to 3 significant figures).
