What is permafrost? a. dry desert soil c. ice on the tundra b. muddy soil d. soil that is always frozen
Answer:
d. soil that is always frozen
Explanation:
Permafrost is the layer of ground that remains frozen the complete year. Soil, rocks and sediments collectively together forms the permafrost. Such soil may remain frozen for a period of two or more than two years. A large part of the Earth's surface has been covered by the layer of permafrost. These are found mainly near the high mountains and especially near North and South poles.

3. A sample of air in a syringe exerts a pressure of 1.02 atm at 22.0°C. The syringe is placed in a boiling-water bath at 100.0°C. The
pressure is increased to 1.23 atm by pushing the plunger in, which reduces the volume to 0.224ml What was the initial volume?
Answer:
0.214 mL
explanation:
Ideal Gas law is applied to the ideal gases. The initial volume of air in the syringe when applied pressure and reducing the volume to 0.2234 mL is 0.214 mL.
What is the Ideal Gas Equation ?The equation relating all the characteristics of a gas and behaving or assuming to be ideal is the ideal gas law equation.
pV = nRT
Here, p is the pressure, V is the volume, R is the universal gas constant, n is the number of moles and T is the temperature.
According to the law, the initial and final values of gas are related as
[tex]\dfrac{P_{1} V_{1} }{T_{1} } =\dfrac{P_{2} V_{2} }{T_{2} }[/tex]
The initial pressure P₁ is 1.02 atm and final pressure P₂ is 1.23 atm.
The initial temperature T₁ is (22+273)=295 K and the final temperature (100+273)=373 K
The final volume V₂ given is 0.224 mL
Placing the values into the ideal gas equation and solving, we get the value of initial volume.
V₁= 0.214 mL
The initial volume of air in the syringe when applied pressure and reducing the volume to 0.2234 mL is 0.224 mL.

Which two statements describe what happens to the nuclei of atoms during a fusion reaction? O A. Large nuclei break apart into two or more smaller nuclei. O B. A small amount of mass in the nuclei that combine is converted to energy. O c. Each nucleus formed has fewer protons than each original nucleus had. O D. Nuclei with small masses combine to form nuclei with larger masses.
Answer:
D. Nuclei with small masses combine to form nuclei with larger masses.
B. A small amount of mass in the nuclei that combine is converted to energy
Explanation:
A nuclear fusion, in contrary to fission, is the process by which the nuclei of two atoms combine to form a much larger atom with a large nuclei. Likewise, during a fusion reaction, a large amount of energy is released from the small amount of mass in the nuclei (two) that combines.
According to this question, the following are true of a fusion reaction:
- Nuclei with small masses combine to form nuclei with larger masses.
- A small amount of mass in the nuclei that combine is converted to enormous energy.

A child drops a ball from a bridge. The ball strikes the water under the bridge 2.0s later. What is the velocity of the ball when it hits the water
Answer:
20m/s
Explanation:
Given that :
Time, t = 2 seconds
Using the relation :
v = u + at
a = g is positive (downward)
V = final velocity
u = initial velocity = 0
v = u + gt
v = 0 + 10(2)
v = 20 m/s

Explanation:
The percentage composition of acetic acid is found to be 39.9% C, 6.7% H, and 53.4% O. What is the empirical formula of acetic acid?
Answer:
CH₂O
Explanation:
From the question given above, the following data were obtained:
Carbon (C) = 39.9%
Hydrogen (H) = 6.7%
Oxygen (O) = 53.4%
Empirical formula =?
The empirical formula of acetic acid can be obtained as follow:
C = 39.9%
H = 6.7%
O = 53.4%
Divide by their molar mass
C = 39.9 / 12 = 3.3
H = 6.7 / 1 = 6.7
O = 53.4 / 16 = 3.3
Divide by the smallest
C = 3.3 / 3.3 = 1
H = 6.7 / 3.3 = 2
O = 3.3 / 3.3 = 1
The empirical formula => CH₂O

1.) List the actual volume of titrant needed to produce a color change for Sample A and Sample B. Answer:
Volume of titrant needed to produce a color change for Sample A: ___ ml Volume of titrant needed to produce a color change for Sample B: ___ ml
2.) There are many aspects to the technique known as titration that are extremely important if results are to be accurate. In a traditional or authentic laboratory setting, these techniques are important and sometimes delicate. List two of the techniques used in this lab that provided you will the most accurate possible results. Describe why these techniques are important and how ignoring the techniques would affect the lab.
Answer:
Technique #1: …
Why technique is important: …
Technique #2: …
Why technique #2 is important: …
3.) The titration procedure you have just performed is similar to what is carried out by water-quality workers throughout the world. They use a kit to perform titration on location instead of in a laboratory. In real-life situations, workers collect water samples in a lake or stream. In lakes and streams calcium carbonate (CaCO3) causes alkalinity. Calcium carbonate acts as a buffer, a substance that serves to resist small changes in acidity or alkalinity in a solution. When acid rain enters lake water, it can be neutralized by the bases present and thus the lake does not become too acidic. Since the key ion is the hydroxide ion, the nature of the location doesn’t matter in this case. All over the world, right now, pollution workers are measuring calcium carbonate in lakes and streams.
If a worker studied two lakes and Lake X had a greater ppm (concentration in parts per million) of calcium carbonate than Lake Z, and both lakes are the exact same size, which of the two lakes would be able to withstand a greater amount of rain that is acidic? Explain your answer.
Answer:
Lake ___ would be able to withstand a greater amount of acid rain.
