Use this image of a greenhouse to help explain how the Earth gets heated through the greenhouse effect.
Answers
Answer/Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.

How many liters of carbon dioxide will be produced at STP if 3.56 g calcium carbonate reacts completely with carbon dioxide? CaCO3 --> CaO + CO2
Answers
Answer:
V = 0.798 L
Explanation:
Hello there!
In this case, for this gas stoichiometry problem, we first need to compute the moles of carbon dioxide via stoichiometry and the molar mass of starting calcium carbonate:
[tex]3.56gCaCO_3*\frac{1molCaCO_3}{100gCaCO_3} *\frac{1molCO_2}{1molCaCO_3} =0.0356molCO_2[/tex]
Next, we use the ideal gas equation for computing the volume, by bearing to mind that the STP conditions stand for a pressure of 1 atm and a temperature of 273.15 K:
[tex]PV=nRT\\\\V=\frac{nRT}{P}\\\\V=\frac{0.0356mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm} \\\\V=0.798L[/tex]

How many joules of heat are required to raise the temperature of 320.0 grams of water from 24.2°C to 50.8°C? Heat capacity of water is 4.2 J/g°C.
Answers
Answer:
35750.4 Joules
Explanation:
Using the formula as follows;
Q = m × c × ∆T
Where;
Q = amount of heat (joules)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
According to the provided information,
mass (m) = 320.0 grams
c = 4.2 J/g°C
∆T = (50.8°C - 24.2°C) = 26.6°C
Q = ?
Using; Q = m × c × ∆T
Q = 320 × 4.2 × 26.6
Q = 35750.4 J

Which of the following is not a force
A. Weight
B. Friction
C. Acceleration
D. Air resistance
Answers
Answer:
Acceleration
Explanation:
Acceleration doesn't change one moment to the next, and therefore, doesn't count as a force.
The answer option which is not a force is: C. Acceleration.
What is a force?A force can be defined as a push or pull of an object or physical body, which typically results in a change of motion (acceleration), especially due to the interaction of the object with another.
The examples of a force.In Science, the three (3) most common examples of a force include the following:

You have a gas that has a pressure of 2 ATM and a volume of 10 L. What would be the new volume if the pressure was changed to 1 ATM ?
Answers
Answer:
20 LExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{2 \times 10}{1} = 20 \\ [/tex]
We have the final answer as

if the solution is acidic, which ion is found in greater concentration?
Answers
Answer:
An acidic solution has a high concentration of hydrogen ions (H +start superscript, plus, end superscript), greater than that of pure water.
The acidic solution indicates the highest concentration of hydrogen or the proton ion in the solution.
What is acidity?Acidity is the measure of the hydrogen ion in the solution by the pH scale and gives the acidic or basic characteristics to the solution.
The concentration of the hydronium or the hydroxide in the solution is a way to determine the acidic basic nature and the pH and pOH of the solution.
Therefore, in an acidic solution hydrogen ions are in the greatest concentration.

years.
A)
The land will be forested once again.
B)
The plot of land will be covered with grasses and flowers.
C)
The weeds will be replaced by woody shrubs and some small trees.
Answers
Answer:
C
Explanation:
The weeds will be replaced by woody shrubs and some small trees.
If the forest land is cleared, it is hard to construct a forest again. The cleared land will grow as grass land then if there is no constructions or buildings fills the land. Hence, option B is correct.
What is forstation?Forestation is the process of formation of forests and dense growth of trees and other kinds of plants. Forests are example of ecosystems and wide variety of plant species and animals are living there.
Nowadays, deforestation is common for the selfish purposes of man to buildups their own amenities so that, many more plants and animals are on the edge of extinction.
There are naturally made forests as well as man made forests. It was results of hard working that to form a forest with all its atmosphere and biodiversity will take longer time. It will not happen within just five years.
Thus, if the forest land is cleared, the empty ground may fill with grasses and flower plants. Hence option B is correct.

Answers
Answer: The balanced equation is [tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.
For example, [tex]AlCl_{3} + Cs \rightarrow CsCl + Al[/tex]
Here, number of atoms on reactant side are as follows.
Al = 1Cl = 3Cs = 1Number of atoms on product side are as follows.
Al = 1Cl = 1Cs = 1To balance this equation, multiply Cs by 3 on reactant side and multiply CsCl by 3 on product side.
Hence, now the equation will be as follows.
[tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]
Here, number of atoms on reactant side are as follows.
Al = 1Cl = 3Cs = 3Number of atoms on product side are as follows.
Al = 1Cl = 3Cs = 3Thus, we can conclude that this equation is balanced.

The molar mass of a substance (Atom or molecule) is defined as the mass in grams that 1 mole of substance (6x10²³ particles of this substance) weighs. Using the periodic table of elements we can know the molar mass of each atom.
For example, the molar mass of Calcium is 40.078g / mol.

Aluminium hydroxide and barium nitrate are produced as a result of the chemical reaction between barium and aluminium nitrate. The reaction's balanced equation is as follows: [tex]2 Al + 3 Ba (NO_3)_3 \rightarrow 3 Ba(NO_3)_2 + 2 Al(OH)_3[/tex]
Chemical reactions are essential natural processes that take place and are in charge of the innumerable alterations and transformations we experience every day. They include the forming and breaking of chemical bonds between atoms, which causes the atoms to be rearranged to produce new compounds with various properties. The concepts of mass and energy conservation control chemical processes. The idea of balanced chemical equations came about because the total number of atoms of each element involved in a reaction stays constant both before and after the reaction. Aluminium hydroxide and barium nitrate are produced as a result of the chemical reaction between barium and aluminium nitrate. The reaction's balanced equation is as follows: [tex]2 Al + 3 Ba (NO_3)_3 \rightarrow 3 Ba(NO_3)_2 + 2 Al(OH)_3[/tex]

Why UV light is so harmfull for some vitamins?In general, temperature, oxygen, and light impacts on vitamins and minerals are sensitive. A nutrient can lose its biological potency if its molecular structure is slightly altered.Numerous vitamins, including vitamin A, vitamin B2 (riboflavin), vitamin B6, vitamin B12, and folic acid, are known to be particularly susceptible to UV radiation oxidation.Additionally, light speeds up the negative interactions between vitamins.For instance, the combination of riboflavin and light together speeds up the breakdown of both folic acid and vitamin C. This is what causes milk that has been exposed to light to lose vitamin C.Thus to conclude we can say that UV light damages some vitamins by reacting with them.
