The chemical added to natural gas in case of gas leaks is mercaptan added to provide a strong odor in case of gas leaks as natural gas is odorless and colorless.
What are the uses of Natural Gas?Natural gas is used in the business sector as well as in households to cook, heat water, run refrigeration and air-conditioning systems, cook, dry clothing, and light up the night.
Methane is the principal carbon substance in natural gas. Natural gas is tasteless, colorless, and odorless, so gas companies add mercaptan to give it an unpleasant stench that can be used to detect leaks in natural gas pipes.
Natural gas is given the chemical mercaptan in order to make leaks simpler to find. The most crucial fact about mercaptan is that it smells bad. It has been compared by some to the stench of rotting eggs. Its odor is quite intolerable in concentrated form.

In general, an organism will be more likely to develop phobias of __________.
In general, an organism will be more likely to develop phobias of dangers faced during natural circumstances.
Phobia is an unjustified or pathological fear of situations or circumstances that are not dangerous and that most people do not find bothersome. Fear is a natural reaction or an adaptive experience to situations or objects that imply a real danger.When this fear occurs before natural circumstances that do not pose a real danger, then we find this fear is no longer adaptive is what we call a phobia.
Therefore, we can conclude that an organism will be more likely to develop phobias of dangers faced during natural circumstances.

What is a Periodic Table?All identified chemical elements are arranged in rows (referred to as periods) and columns (referred to as groups) in the periodic table of chemical elements, also known as the periodic table, in ascending order of atomic number.
According to Los Alamos National Laboratory, the periodic table's horizontal rows are known as periods, and each period number represents the number of orbitals for the elements in that row.
Atoms have protons and neutrons as their nucleus. Outside of that are their electrons, which are grouped in orbitals; an atomic orbital is a mathematical concept that refers to the position of an electron and its wave-like activity.
According to the Royal Society of Chemistry, Russian chemist and inventor Dmitri Mendeleev are regarded as the "father" of the periodic table (opens in new tab). Mendeleev was a well-liked instructor in the 1860s at a Russian institution in St. Petersburg.

Sulfur tetrafluoride, sf4, reacts slowly with oxygen, o2, to form sulfur tetrafluoride monoxide, osf4, according to the following unbalanced reaction: sf4(g)+o2(g)→osf4(g)when the equation is balanced, what are the coefficients?.
Let a, b, c be the coefficients of the balanced reaction
a SF₄ + b O₂ ⇒ c OSF₄
The atom counts for each element among the reactants should be the same as with the products:
• S : a = c
• F : 4a = 4c
• O : 2b = c
If b = 1, it follows that a = c = 2. So the balanced reaction is
2 SF₄ + 1 O₂ ⇒ 2 OSF₄

A player pays $15 to play a game in which a chip is randomly selected from a bag of chips. The bag contains 10 red chips, 4 blue chips, and 6 yellow chips. The player wins $5 if a red chip is selected, $10 if a blue chip is selected, and $20 if a yellow chip is selected. Let the random variable x represent the amount won from the selection of the chip, and let the random variable w represent the total amount won, where w=x−15. What is the mean of w ? $10. 50 answer a: $10. 50 a $4. 50 answer b: $4. 50 b −$4. 50 answer c: negative 4. 50 dollars c −$6. 50 answer d: negative 6. 50 dollars d −$10. 50.
The mean of the random variable w that represents the total amount won is; -$4.50
We are given quantity of chips inside the bag as;
Number of red chips = 10Number of blue chips = 4Number of Yellow chips = 6Total number of chips = 20
Thus;
P(Red chips) = 10/20 = 0.5P(blue chips) 4/20 = 0.2P(Yellow Chips) = 6/20 = 0.3Amount won from the selection of Red Chip = 0.5 * $5 = $2.5
Amount won from the selection blue Chip = 0.2 * $10 = $2
Amount won from selection of yellow chip = 0.3 * $20 = $6
Thus;
x = $2.5 + $2 + $6
x = $10.5
We are told that total amount won is gotten from;
w = x − 15
Thus;
w = 10.5 - 15
w = -$4.50

Select the correct answer. What is the domain of this radical function? a. [3, [infinity]) b. [-3, [infinity]) c. [1, [infinity]) d. [-1, [infinity]).
The domain of a function is the set of input values the function can take
The radical function is not given; so, I will provide a general explanation
Assume the radical function is:
[tex]f(x) = \frac{1}{\sqrt{12- 2x}}[/tex]
The denominator of the above function cannot be negative.
So, we express the denominator as follows
[tex]12-2x > 0[/tex]
Subtract 12 from both sides
[tex]-2x > -12[/tex]
Divide both sides by -2
[tex]x < 6[/tex]
So, the possible values of x the function can take are less than 6
Hence, the domain of the radical function is [tex][-\infty,6][/tex]

Which segments show changes of state that release heat? check all that apply. B–a c–b d–c e–d f–e.
Answer:
Answer is C-B and E-D
Explanation:
(B) & (D) Good luckk!:)
B - C and E - D are the segments show changes of state that release heat. Hence option 2 and 4 is correct.
What are segments?Segments are defined as a part of a company that produces its own products, product lines, or service offers and makes its own profits. A segment is a specific length portion of a line with two endpoints. On the other hand, a ray is also a component of a line that has one terminus and an infinitely long other direction.
The material is converting from a solid to a liquid in segments B and C. Since the heat is being used to separate the particles from the solid and transport them into the liquid phase, there is no change in temperature. The material is transitioning from a liquid to a gas in segments D to E. . Because the heat is being used to separate the particles from the liquid and transport them into the gas phase, there is no change in temperature.
Thus, B - C and E - D are the segments show changes of state that release heat. Hence option 2 and 4 is correct.

Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes can be modeled by the equation t(t)=ts+(t0−ts)e−kt, where ts is the surrounding temperature and k is the substance’s cooling rate. A liquid substance is heated to 80°c. Upon being removed from the heat, it cools to 60°c in 15 min. What is the substance’s cooling rate when the surrounding air temperature is 50°c? round the answer to four decimal places. 0. 0687 0. 0732 0. 0813 0. 872.
The cooling rate of the substance is approximately 0.0732.
According to the statement, the Newton's law of cooling is defined by the following formula:
[tex]T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t}[/tex] (1)
Where:
[tex]T_{s}[/tex] - Final temperature, in degrees Celsius.[tex]T_{o}[/tex] - Initial temperature, in degrees Celsius.[tex]t[/tex] - Time, in minutes.[tex]k[/tex] - Cooling rate, in [tex]\frac{1}{min}[/tex].[tex]T(t)[/tex] - Current temperature, in degrees Celsius.Please notice that substance reaches thermal equilibrium when [tex]T(t) = T_{s}[/tex], that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that [tex]T_{o} = 80\,^{\circ}C[/tex], [tex]t = 15\,min[/tex], [tex]T_{s} = 50\,^{\circ}C[/tex] and [tex]T(15) = 60\,^{\circ}C[/tex], then the cooling rate of the substance is:
[tex]60 = 50 + (80 - 50)\cdot e^{-15\cdot k}[/tex]
[tex]\frac{60-50}{80-50}= e^{-15\cdot k}[/tex]
[tex]\frac{1}{3} = e^{-15\cdot k}[/tex]
[tex]k = -\frac{1}{15}\cdot \ln \frac{1}{3}[/tex]
[tex]k \approx 0.0732[/tex]

The table below shows the number of protons, neutrons, and electrons in four ions.
The atom that has a charge of -1 is atom 3.
To get the net ionic charge, we will use the formula as shown:
Net ionic charge = Number of protons present in an ion + Number of electrons present in an ion.For atom 1;
Net ionic charge = 9 - 9
Net ionic charge = 0
For atom 2;
Net ionic charge = 9 - 8
Net ionic charge = + 1
For atom 3;
Net ionic charge = 9 - 10
Net ionic charge = -1
For atom 4;
Net ionic charge = 9 - 9
Net ionic charge = 0
From the calculation above, the atom that has a charge of -1 is atom 3.
