Answer: A meteorologist predicts fog in the morning over lakes and river bottoms because of the atmospheric conditions and their interactions with the hydrosphere. The hydrosphere is the region on the Earth's surface where the total water on the planet is found. The hydrosphere can be in the form of liquid, vapor, or ice.

Which aqueous solution of KI freezes at the lowest temperature?(1) 1 mol of KI in 500. g of water
(2) 2 mol of KI in 500. g of water
(3) 1 mol of KI in 1000. g of water
(4) 2 mol of KI in 1000. g of water

Answers

The answer is (2) 2 mol of KI in 500. g of water.. This is a question of colligative properties. Boiling point elevation and freezing point depression depend on the concentration of dissolved solute. You would get the greatest concentration of KI with the largest moles of KI and smallest volume of water.

Describe several uses for plastic and explain why plastic is a good choice for these properties

Answers

Plastics are used in almost all spheres of life for diverse purposes because of their beneficial properties. The uses of plastics include the following:

1. Plastics are used in the manufacturing of various items that we use in our homes such as television, phones, radio, vacuum cleaners, chairs, bowls plates, tables, etc.

2. Plastics are used in the food industry for packaging of foods.

3. Plastics are used in the transport industry for various purposes in the manufacture of cars, trains, aeroplanes, hydroplanes, ships, satellites, etc.

4. Plastics are also used in the medical and pharmaceutical industries for various purposes.

Manufacturers are able to use plastics for various purpose because of their properties, which include: resistance to corrosion, resistance to chemicals, low thermal conductivity, color variability, high strength to weight ratio, resistance to shock, durability, low toxicity, ready availability, cheap, etc.
Plastic is used in several in the worlds toys, bags and products. Its a good choice for these properties because plastic is a low cost and is very durable and flexible allowing it to ease the process of making these products.

Did Pb2+ react with KI? Yes or No? State the reason of your answer.

Answers

Yes, Pb2+ react with KI.

Pb2+ is lead (II) ion
KI is a compound. It is a combination of potassium (K) and iodine (I). It is called potassium iodide.

Both potassium and iodine are highly reactive elements. Thus, when they are combined with another element like Pb2+, Pb2+ reacts with KI

Answer: Yes, lead ion will react with potassium iodide.

Explanation: When lead ion reacts with KI, a bright yellow colored precipitate is formed.

The reaction of these two follows:

Pb^(2+)(aq.)+2KI(aq.)\rightarrow PbI_2(s)+2K^+(aq.)

Hence, Pb^(2+) ion reacts with KI to yield PbI_2

This test is the confirmatory test for lead ion which is present in Group I.

How are regional climate patterns caused by atmospheric and ocean flows

Answers

Answer:

Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. .

If a runner completes a 10 kilometer race in 32.50 minutes, what is the 10.0 km pace in miles per hour? (1.609 km = 1 mile approximately)

Answers

If a runner completes a 10 km race in 32.5 minutes, his pace or speed can be calculated by the equation:

velocity = distance/time = 10km/32.5 mins = 0.3125 km/min

Convert this value to miles per hour using the conversion factors for minutes to hours and kilometers to miles as requested by the problem. This gives an answer of 11.47 miles per hour.

0.3125 km/min x 60 mins./ 1 hour x 1 mile / 1.609 km = 11.47 miles/hour
