Explanation:

Answer:

S

Explanation:

Using periodic table (see those little numbers in the upper right?  Those are electron 'shells' .... look at the bottom one)

Ca has 2     Cl has 7       Ne has 8        S  has 6 in the outermost shell

Using the given formula, the density of the material is 2.015 g/mL

From the question, we are to determine the density of the material

From the given formula

Density = Mass / Volume

And from the given information,

Mass = 65.5 g

and volume = 32.5 mL

Putting the parameters into the equation,

Density = 65.5/32.5

Density = 2.015 g/mL

Hence, the density of the material is 2.015 g/mL.

Answer:

=71.439911 u

Explanation:

We know that 1 mass of hydrogen atom = 1.00784 u

If it's measured at 72u: 72/1.00784=71.439911 u

Mass of 1 mol hydrogen atoms =1.00784u

Total mass in 72u

Dust clouds that moved to the east coast of the united states were composed mostly of silt and clay particles due to constant ploughing during drought.

This is defined as dry period in the climate due to insufficient rainfall in the area at a given time.

The drought led to the soil being constantly ploughed thereby loosening and changing the soil type which is susceptible to wind erosion.

The partial pressure of the hydrogen gas, if the water vapor pressure is 3.17kPa is 91.83 kPa.

Dalton's law of gas states that total pressure of the mixture of gas is equal to the sun of the partial pressure of the individual gas.

Given that,

Total pressure of hydrogen gas = 95 kPa

Partial pressure of water vapor = 3.17 kPa

Partial pressure of hydrogen gas will be calculated as:
Partial pressure = 95 - 3.17 = 91.83 kPa

Hence required partial pressure is 91.83 kPa.
