The image below shows part of a rounded ridge formation called an esker. This esker extends for several miles in an area that is
mostly flat plains. At one time, this ridge shape was occupied by a stream that flowed underneath a large glacier
Which of the following describes how the esker most likely formed?
ОА
As the glacier receded, the sediments in the stream built up to result in the formation
Св.
The glacier eventually melted and the water eroded the areas on both sides of the ridge
C. As the glacier receded, tectonic forces formed volcanoes, which spewed lava and formed igneous rock

Determine the molarity of a solution with a volume of 435. mL and 0.550 mol of solute dissolved.
Answer:
M = 1.26
Explanation:
Molarity = mole of solution/liters of solution
435mL/1000 = .435L
Plugging in the numbers into the formula, we get:
Molarity = .550 mol/.435L = 1.26 M

Explain how nitrogen oxides released into the atmosphere can lead to the formation of a secondary pollutant that can lead to acid deposition.
Nitrogen oxides react with oxygen and rainwater to form nitric acid a secondary pollutant which dissolves in water droplets forming acid rain.
What is a secondary pollutant?A secondary pollutant is a pollutant which results from changes that occur in an initial pollutant known as the primary pollutants.
Pollutants pose dangers to plant and animals found in a given environment.
The primary pollutant, nitrogen oxides, which are released into the atmosphere from industrial and vehicular smoke can be changed into a secondary pollutant.
Nitrogen oxides react with oxygen and rain to form nitric acid a secondary pollutant.
Nitric acid (HNO3) then enter the environment through the ground as droplets in rain forming acid rain.

Alkali metals are not reduced because they are obtained by chemical reduction of their oxides.
The relative atomic mass of an element is the mass of its atoms compared with that of which
element? Give the name, not the symbol.
The relative atomic mass of an element is compared with the mass of an atom of carbon-12.
Carbon-12 is chosen as the reference because it has a mass of exactly 12 atomic mass units (amu). The relative atomic mass, also known as atomic weight, provides a standard for comparing the masses of different elements.
It is calculated based on the weighted average of the masses of an element's naturally occurring isotopes, taking into account their abundance. By using carbon-12 as the reference, scientists establish a consistent scale for expressing atomic masses.
This standardization is essential for accurately conveying the mass of atoms in a way that is universally understandable and comparable across various elements and compounds.

The release of water vapor from sweat glands when we are not sweating is a process called:.
From what we know, we can confirm that the release of water vapor from sweat glands when we are not sweating is a process called insensible perspiration.
What is insensible perspiration?This is a process by which we emit water in the form of vapor from our skin. This process is not to be confused with normal sweating. This happens at a near-constant rate in the human body and is not perceivable. The loss of water through this method also helps the body to maintain its homeostasis levels.
Therefore, we can confirm that the release of water vapor from sweat glands when we are not sweating is a process called insensible perspiration.

A particular species of bird can fly for 36.0 hours straight, covering a distance of 158 miles. At this rate, how many feet does the bird travel in 43.0 min?
Answer:
16607 and 5/9 feet
Explanation:
First, let's find the how fast the bird travels in an hour. Finding the miles per hour: 158/36=79/18. Convert this to miles per minute to find the distance after 43 mins. Multiplying 79/18 by 1/60, 79/1080. Multiplying this by 43 to find the distance traveled; 3397/1080. As 1 mile is equal to 5280 feet, multiply by 5280 to find distance in feet. Once this is all done, you get 149468/9, or 16607 and 5/9 feet.

O B.
B. Tihin atoms will always combine to give off energy
Tuhin atoms
O c. That energy can only be converted between different forms
O D. That kinetic energy can only be converted to heat
Answer:
B. That energy can only be converted between different forms
Explanation:
The law of conservation of energy implies that energy can only be converted between different forms but can neither be created nor destroyed.
Energy is the ability to do work. It is very important physical quantity that is essential to all life forms.
Energy according to the law of conservation of energy is not produced neither is it destroyed.
Energy is simply transformed from one form to another.

Part 1: What is the half-life of the element? Explain how you determined this.
Part 2: How long would it take 308 g of the sample to decay to 4.8125 grams? Show your work or explain your answer
1. The half-life of the element is 22 years
2. The time taken for 308 g of the sample to decay to 4.8125 g is 132 years
Definition of half-lifeHalf-life is simply defined as the time taken for half of a material to decay.
1. How to determine the half-life Original amount (N₀) = 45 gHalf of the original amount = 45 / 2 = 22.5 gFrom the diagram, the time for 22.5 g is 22 years.
Thus, the half-life of the element is 22 years
2. How to determine the time i. Determination of the number of half-lives Original amount (N₀) = 308 gAmount remaining (N) = 4.8125 gNumber of half-lives (n) =?2ⁿ = N₀ / N
2ⁿ = 308 / 4.8125
2ⁿ = 64
2ⁿ = 2⁶
n = 6
ii. Determination of the time Number of half-lives (n) = 6Half-life (t½) = 22 yearsTime (t) =?t = n × t½
t = 6 × 22
t = 132 years
