Moving on to the second issue
Let's tackle the second question first. Once you grasp that, the first question will be simpler. By the way, this is an excellent question to clarify. The concepts of less than and more than can be quite tricky in the sciences. Every question you encounter that utilizes less or more should be approached with caution.
As altitude increases, air pressure decreases (essential term: less highlight this sentence in color. Take a moment to reflect on it.)
As the pressure declines, less energy (again, key term) is required for water molecules to escape the surface. Thus, the boiling temperature is lower than it would be at sea level.
Answer to problem two: Lower
Problem One
Water reaches its boiling point when the greatest number of molecules can leave the water's surface. Equal to is the right answer. Although pinpointing the exact answer can be challenging, equal to is indeed the correct response.
Response:
The mass percentage of a solution comprising 7.6 grams of sucrose and 83.4 grams of water equals 8.351 %.
Details:
Provided data:
Sucrose mass = 7.6 grams
Water mass = 83.4 grams
In this scenario, sucrose acts as the solute, while water is the solvent.
The calculation for mass percent of a solution is done using the following formula:
Mass percent = (Mass of Solute/Mass of Solution)(100)
As sucrose is the solute, the mass equals 7.6 grams.
The total mass of the solution, which includes both sucrose and water, comes out to:
Total mass = 7.6 grams + 83.4 grams = 91 grams
Therefore, applying the values gives mass percent = (7.6/91)(100) = 8.351 %.
Answer:
The vehicle travels 660 feet
Explanation:
Initially, convert the speed into Feet per second
The car's speed is 90 mi/hr
1 mi = 5280 ft
For 90 miles, we calculate 90 x 5280 = 475,200 feet
1 hour = 60 minutes
1 minute = 60 seconds
Therefore,
1 hour = 60 x 60 seconds = 3600 seconds
Speed is defined as the distance covered by an object over time. The speed formula is:
... given
Speed = 132 ft/sec
Thus, time = 5 seconds
Distance = 660 feet
The amino acids classified under the first group include alanine, aspartate, and glutamate, whereas those in the second group consist of glycine, valine, proline, leucine, isoleucine, methionine, serine, threonine, cysteine, asparagine, glutamine, phenylalanine, tryptophan, tyrosine, lysine, arginine, and histidine.
