Please help! Which halogen has the strongest IMF and why? ​

Answer:

• 17.6 g of chlorine gas reacted.

Explanation:

1) Chemical equation:

• 2Na + Cl₂ (g) → 2NaCl (s)

2) Mole ratios:

• 2 mol Na : 1 mol Cl₂ : 2 mol NaCl

3) Number of moles of sodium chloride (NaCl) measured (produced):

• Number of moles = mass in grams / molar mass

• Molar mass of NaCl = 58.44 g/mol

• Number of moles of NaCl = 29.0 g / 58.44 g/mol = 0.496 mol

4) Number of moles of chlorine gas (Cl₂) reacted:

• From the stoichiometric mole ratios:

       1 mol Cl₂ / 2 mol NaCl = x / 0.496 mol NaCl

       x = 0.496 mol NaCl / 1 mol Cl₂ / 2 mol NaCl = 0.248 mol Cl₂.

5) Convert 0.248 mol Cl₂ into mass in grams:

• mass in grams = molar mass × number of moles

• molar mass of Cl₂ = 70.9 g/mol

• mass in grams = 70.9 g/mol × 0.248 mol = 17.6 g ← answer

The answer is: D. Biological precipitation.

Biological precipitation is the deposition of minerals from solution by the agency of organisms.

Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass.

Ocean sediments originate from numerous sources:

1) biological activity (biogenous).

2) weathering and erosion of the continents (terrigenous/lithogenous).

3) volcanic eruptions (volcanogenous).

4) chemical processes (hydrogenous).

Calcium carbonate (CaCO₃) is made of calcium, carbon and oxygen atoms.

Among the substances listed, ammonia (NH3) is a compound. The option D (ammonia) is the correct option.

Compound Substance

• A compound substance refers to a type of substance that is composed of two or more different elements chemically combined in fixed proportions. In other words, it is a substance formed when atoms of different elements bond together to form molecules. The elements in a compound substance are chemically bonded, meaning they are held together by chemical forces such as covalent bonds, ionic bonds, or metallic bonds.

Compounds can have various physical forms, such as solids, liquids, or gases, depending on the specific elements and the nature of their chemical bonds. They can also exhibit a wide range of chemical and physical properties, such as melting point, boiling point, density, solubility, and reactivity.

Chemical formulas are used to represent compound substances, indicating the types and numbers of atoms present in a molecule of the compound. For example, the chemical formula for water is H2O, representing two hydrogen (H) atoms bonded to one oxygen (O) atom. Ammonia is composed of nitrogen (N) and hydrogen (H) atoms bonded together. Carbon (C), chlorine (Cl), and uranium (U) are elements rather than compounds.

Therefore, Ammonia which is option D is the correct option.

Answer:

Ammonia

Explanation:

Ammonia is a inorganic compound that is made up of single nitrogen atom.

Answer:

The rock was larger than last summer, ice wedging caused it to expand.

Explanation:

Ice wedging is a process that happens when water gets into the cracks of concrete, stones, other forms of the Earth, and freezes. When the water freezes, it expands and pushes the rock from the crack which either separates and turns it into two rocks, or the rock might form together again and just be a larger rock. This process happens in Winter and usually finished in Spring when the ice between the rocks melt. I have described the process of ice wedging for you.

The molecule is thiophosgene or CSCl₂.

Explanation:

As the informations given, the molecule contains 12.17 grams of carbon, 32.53 g of sulfur, and 72.19 g of chlorine.

Molar mass of carbon =12.

Molar mass of sulphur =32.

Molar mass of chlorine =35.

So on an average estimation, one mole of the molecule contains one mole of carbon atoms, one mole of Sulphur atoms and two moles of chlorine atoms. Molar mass of an element is the average weight of one mole of atoms of that element which is made average according to the variations of percentage availability of isotopes of that element on earth.

So the estimated molecule is CSCl₂ or thiophosgene.
