Which of the following might be an indicator of global warming?A. average increase in the temperatures near Earth's surface
B. a decrease in greenhouse gases
C. average decrease in the temperatures near Earth's surface
D. a decrease in carbon dioxide emissions

Answers

Answer 1
Answer:

Answer: The correct answer is A. average increase in the temperatures near Earth's surface

Explanation: The reason this is correct is that global warming is it getting hotter, logically the temperatures near Earth's surface will be getting hotter as well. Hope this helps

Which process melts an ore to separate useful metals from the rest of the elements in the ore? smelting, mining, prospecting, alloys

Answers

The process melts an ore to separate useful metals from the rest of the elements in the ore is called smelting. The ore is heated beyond its melting point to extract the metal with the help of oxidizing agents such as air or reducing agents such as coke.

Find the number of moles of argon in 452 g of argon

Answers

no. of moles = given mass/atomic mass

= 452/40

= 11.3.

Thus, there are 11.3 moles
nó of moles =given mass/molar mass
no of moles=452/39.9
therefore no of moles=11.3moles

sodium chloride and glucose both are soluble in water but the solubility of NaCl is greater then glucose why.

Answers

The solubility of a substance in water depends on several factors, including the nature of the solute and solvent, as well as the intermolecular forces involved.

In the case of sodium chloride (NaCl) and glucose, both substances are indeed soluble in water. However, the solubility of NaCl is generally greater than that of glucose due to differences in their chemical properties.

NaCl is an ionic compound, meaning it consists of positive sodium ions (Na+) and negative chloride ions (Cl-). When NaCl is added to water, the polar water molecules surround the ions and separate them from the crystal lattice. These water molecules form favorable interactions with the charged ions through ion-dipole attractions, resulting in the dissolution of NaCl in water. These strong ion-dipole forces contribute to the high solubility of NaCl in water.

On the other hand, glucose is a covalent compound composed of carbon, hydrogen, and oxygen atoms. It does not dissociate into ions when dissolved in water. Instead, glucose molecules interact with water through weaker intermolecular forces such as hydrogen bonding and dipole-dipole interactions. While these forces allow glucose to dissolve in water, they are relatively weaker than the ion-dipole interactions in NaCl-water solution. As a result, glucose has a lower solubility compared to NaCl in water.

Therefore, the differing chemical properties of sodium chloride and glucose contribute to the higher solubility of NaCl in water compared to glucose.
