Answer:

   D) The volume becomes  two times the original value.

Explanation:

   Since the ATM is doubling in size, so is the pressure. Really, by saying the atm is going up, you’re just saying the pressure is going up, since ATM stand for atmospheric pressure.

A partir de 140 g de n2 y una cantidad de h2 se obtuvo 153G de NH³. Cual es el % de rendimiento de la reacción química
DiKsa [7]

Respuesta:

90.0 %

Explicación:

Paso 1: Escribir la ecuación química balanceada

N₂ + 3 H₂ ⇒ 2 NH₃

Paso 2: Calcular el rendimiento teórico de NH₃ a partir de 140 g de N₂

En la ecuación balanceada, participan de N₂: 1 mol × 28.01 g/mol = 28.01 g y de NH₃: 2 mol × 17.03 g/mol = 34.06 g.

140 g N₂ × 34.06 g NH₃ /28.01 g N₂ = 170 g NH₃

Paso 3: Calcular el rendimiento porcentual de NH₃

El rendimiento experimental de NH₃ es 153 g. Podemos calcular el rendimiento porcentual usando la siguiente fórmula.

R% = rendimiento experimental / rendimiento teórico × 100%

R% = 153 g / 170 g × 100% = 90.0 %

What type of bond would be formed between nitrogen (N) and nitrogen (N)? Why?
Vikki [24]

Answer: The compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Explanation:

If electronegativity difference between two atoms is less than 0.4 then bond formed is a pure covalent bond.

If electronegativity difference between two atoms is between 0.4 to 1.8 then bond formed is a polar covalent bond.

If electronegativity difference between two atoms is greater than 1.8 then bond formed is an ionic bond.

The electronegativity value of a nitrogen atom is 3.04. Hence, the electronegativity difference of N_{2} molecule is as follows.

Electronegativity difference = electronegativity value of N - electronegativity value of N\\= 3.04 - 3.04\\= 0As the electronegativity difference is 0 which is less than 0.4.

Hence, we can conclude that the compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Why is water considered a renewable resource?
Crazy boy [7]

Answer:

Water is a renewable resource because it evaporates out of the oceans to clouds, which generate rain falling on the land. The water then runs into rivers and dams where it is used and the waste is partially cleaned before it makes its route to the sea, where the cycle begins again.
