Answer:

Osmosis is the scientific process of transferring fluid between molecules. When molecules move in and out of a cell to achieve the same concentration of something, like salt, on both sides, then osmosis is happening.

Which sublevels are full when an atom has a noble gas configuration?

NemiM [27]

<h3>Answer:</h3>

s-sub-level and p-sub-level

<h3>Explanation:</h3>

Group 18 elements in the periodic table are known as noble gases.
They have an octet configuration with their outermost s and p-sub-levels full, which makes them inert or nonreactive.
The s-sub-level takes up a maximum of 2 electrons while the p-sub-level holds a maximum of 6 electrons.
They include, argon, neon, xenon, krypton, etc.
Their electron configuration shows full outermost s and p-sub-levels.
For example; the electron configuration of Ne is 1s²2s²2p⁶, with full s and p sub-levels.

What is causing <br> the global average temperature on earth to increase

Serggg [28]

Increase in greenhouse gas emission

Explanation:

Global average temperature of the earth is increasing due to a surge in the amount of greenhouse gases being emitted.

The major greenhouse gas is carbon dioxide.

This gas is produced by a wide range of industrial processes and combustion of fuels in automobiles.

Anomalous concentration of this gas in the atmosphere leads to an increase in earth's temperature.

These gases interacts with long wave radiation produced by the earth and prevents them from escaping. In turn, they warm the earth and keep it at fairly uniform temperature.

When these gases are too much in concentration they lead to an anomalous increase in temperature.

A certain substance X has a normal freezing point of −3.1°C and a molal freezing point depression constant =Kf·6.23°C·kgmol−1. C

muminat

Answer:

Freezing T° of solution = - 7.35 °C

Explanation:

This is about the freezing point depression, a colligative property which depends on solute.

The formula is: Freezing T° pure solvent - Freezing T° solution = m . Kf . i

Freezing T° of pure solvent is -3.1°C

At this case, i = 1. As an organic compound the urea does not ionize.

We determine the molality (mol/kg of solvent)

We convert mass to moles:

12.3 g . 1mol / 60.06 g = 0.205 moles

0.205 mol / 0.3 kg = 0.682 mol/kg

We replace data in the formula:

-3.1°C - Freezing T° of solution = 0.682 mol/kg . 6.23 kg°C/mol . 1

Freezing T° of solution = 0.682 mol/kg . 6.23 kg°C/mol . 1 + 3.1°C

Freezing T° of solution = - 7.35 °C

The molar mass of CO2 is 44.01 g/mol. Which is the mass of 3.21×1025 molecules of CO2

sineoko [7]

Given:

Molar mass of CO2 = 44.01g/mol

3.21x10^25 molecules of CO2

Required:

Mass of CO2

Solution:

Avogadro’s number states that for every mole of atom, there are 6.023x10^23 units of atom. The units may be formula units, atoms. In here, you need to divide 3.21x10^25 molecules of CO2 to 6.023x10^23 molecules per mole.

3.21x10^25 molecules of CO2 / 6.023x10^23 molecules per mole = 53.30 moles CO2

53.30 moles CO2 (44.01g/mol CO2) = 2346 g of CO2
