Primero realizas la configuración electrónica que es la que te puse allá arriba.

Después miras el nivel en que termina, puede ser 1, 2, 3, 4 etc.

Entonces como el último número de la configuración electrónica es 4, entonces ese es el nivel

Y los electrones de el último nivel son los de Valencia

4s2, 4p1 sumas 2+1 que son los electrones que se encuentran en el último nivel.

por eso hay 3 electrones de valencia.

Explain what it means to be considered a “renewable” energy source, and what it means to be a “non-renewable” energy source.
Neporo4naja [7]

Answer: Resources are characterized as renewable or nonrenewable

- a renewable resource can replenish itself at the rate it is used such as solar energy, wind energy, hydro energy, and tidal energy.

- a nonrenewable resource has a limited supply such as coal, gas, nuclear energy, and fossil fuels.

The feed to a batch process contains equimolar quantities of nitrogen and methane. write an expression for the kilograms of nitr
timama [110]
1) number of moles of N2 = n/2

2) Number of moles of CH4 = n/2

3) Total number of moles of the mixture = n/2 + n/2 = n

4) Kg of N2

mass in grams = number of moles * molar mass

molar mass of N2 = 2 * 14.0 g/mol = 28 g/mol

=> mass of N2 in grams = (n/2) * 28 = 14n

mass of N2 in Kg = mass of N2 in grams * [1 kg / 1000g] = 14n/1000 kg = 0.014n kg

Answer: mass of N2 in kg = 0.014n kg

Explain why ice is able to float on water
agasfer [191]

Ice floats because it is about 9% less dense than liquid water. ... The heavier water displaces the lighter ice, so ice floats to the top. One consequence of this is that lakes and rivers freeze from top to bottom, allowing fish to survive even when the surface of a lake has frozen over

Which of the following items is a salt? (1 point)
Tems11 [23]

  • Calcium carbonate is the  salt  among the given options.

  • Calcium carbonate ( CaCO3) can be regarded as  which appears as white and odorless powder or  as a colorless crystals it is  insoluble in water.

  • The chemical  formula is CaCO3. It can be used as an antacid as well as food colouring and a  food firming agent and a fertilizer.

  • Calcium carbonate is calcium salt as well as carbonate salt with one-carbon compound

  • Salt can be regarded as substance which is  produced by reaction between acid and  base. It  consists negative ion (anion) of that acid as well as positive ion (cation) of the base.

  • Sodium hydroxide is a base and not a salt

  • Carbonic acid is an acid and not a salt

  • Therefore, calcium carbonate is the only salt in the among the given options.
