Answer: 233 L of [tex]CO_2[/tex] will be produced from 150 grams of [tex]C_4H_{10}[/tex]
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex] [tex]\text{Moles of} C_4H_{10}=\frac{150g}{58g/mol}=2.59moles[/tex]
The balanced chemical equation is:
[tex]2C_4H_{10}+13O_2(g)\rightarrow 8CO_2+10H_2O[/tex]
According to stoichiometry :
2 moles of [tex]C_4H_{10}[/tex] produce = 8 moles of [tex]CO_2[/tex]
Thus 2.59 moles of [tex]C_4H_{10}[/tex] will produce=[tex]\frac{8}{2}\times 2.59=10.4moles[/tex] of [tex]CO_2[/tex]
Volume of [tex]CO_2=moles\times {\text {Molar volume}}=10.4moles\times 22.4mol/L=233L[/tex]
Thus 233 L of [tex]CO_2[/tex] will be produced from 150 grams of [tex]C_4H_{10}[/tex]

Grant's Law
Answer:
Boyle's Law
Explanation:
"Boyle's law, also referred to as the Boyle–Mariotte law, or Mariotte's law, is an experimental gas law that describes how the pressure of a gas tends to increase as the volume of the container decreases."

All you need to know about CO2?
Answer:
Carbon is an element that's found all over the world and in every living thing. Oxygen is another element that's in the air we breathe. When carbon and oxygen bond together, they form a colorless, odorless gas called carbon dioxide, which is a heat-trapping greenhouse gas. Whenever we burn fossil fuels such as coal, oil, and natural gas—whether it's to drive our cars, use electricity, or make products—we are producing carbon dioxide.
The atmosphere isn't the only part of the Earth that has carbon. The oceans store large amounts of carbon, and so do plants, soil, and deposits of coal, oil, and natural gas deep underground. Carbon naturally moves from one part of the Earth to another through the carbon cycle. But right now, by burning fossil fuels, people are adding carbon to the atmosphere (in the form of carbon dioxide) faster than natural processes can remove it. That's why the amount of carbon dioxide in the atmosphere is increasing, which is causing global climate change.

What is a covalent compound?A covalent compound is a molecule formed by covalent bonds, in which the atoms share one or more pairs of valence electrons.
Covalent bond is a type of chemical bond where two atoms are connected to each other by the sharing of two or more electrons.
Chemical compounds are generally grouped into one of two categories as follows;
covalent compounds ionic compoundsCovalent or molecular compounds generally result from two nonmetals reacting with each other. The elements form a compound by sharing electrons, resulting in an electrically neutral molecule.

What is the empirical formula for a compound that has 1.5 moles of copper and 0.5 moles of phosphorus?
Answer:
[tex]Cu_{3}P[/tex]
Explanation:
usually, the first step is to calculate the moles but since that is already given in the question we can move onto the next step
least molar ratio:
Cu = [tex]\frac{1.5}{0.5}[/tex] = 3
P = [tex]\frac{0.5}{0.5}[/tex] = 1
thus, empirical formula = [tex]Cu_{3}P[/tex]
The empirical formula for a compound that has 1.5 moles of copper and 0.5 moles of phosphorus is Cu₃P.
What is the empirical formula?Empirical formula of any compound gives idea about the number of constituents particles present in that compound by mentioning the ration.
In the question, given that:
Moles of copper = 1.5 moles
Moles of phophorous = 0.5 moles
Now we divide the given moles by the smallest number to get the ration number as follow:
Cu : P
1.5/0.5 : 0.5/0.5
3 : 1
Hence, required empirical formula is Cu₃P.

SEP Analyze Data Which two columns have identical data? What do these two columns suggest about the identity of elements?
Answer:
The two columns which have identical data are the Atomic number and the number of protons column. This indicates that the atomic number is equivalent to the number of protons in an element.
Explanation:
Atomic Number is given as the number of electrons in an element. As the number of electrons is required to be equal to the number of protons, for the element to exist in the neutral state. This indicates that the atomic number of an element can also be considered equal to the number of protons in that element.

Explanation:
The Texas Hill Country ecosystem supports a variety of organisms. Animals such as owls, coyote, snakes and hawks compete for small animals for food. What might happen if the population of these predators became too large? The predators would share the prey population equally among all of the predator species. The predators would begin to eat plants rather than their usual prey. The predators would have more offspring of great size. The predators would consume the prey population faster than it could be replaced.
Answer:
The predators would consume the prey population faster than it could be replaced.
Explanation:
According to Oxford dictionary; an ecosystem is "a biological community of interacting organisms and their physical environment."
An ecosystem is a self supporting unit that is composed of living and non living parts. The ecosystem should be self sustaining.
In the particular case mentioned in this question, when the predator population becomes so large, they will steadily diminish the prey population faster it can be replaced thereby distorting the balance of the ecosystem.
A scientist prepares 500.0 L of gas at 0.921 atm pressure

What is the volume of the gas under these conditions?

Answer:
200.0°C.
Explanation:
The resulatant volume of gas under given conditions is 9.49 liters.
What is ideal gas equation?Ideal gas equation gives idea about the behavior of gases at different conditions and it will be represented as:
PV = nRT, where
P = pressure in atm
V = volume in L
n = moles of gas
R = universal gas constant = 0.082 L.atm/K.mol
T = temperature in K
First we calculate the moles of gas by putting the values according to the first condition in the above equation and we have
n = (0.921)(500) / (0.082)(473) = 11.86 moles
Now we calculate the volume of gas by using the above equation and details of the second condition as:
V = (11.86)(0.082)(293) / (30) = 9.49 L
Hence resultant volume of the gas is 9.49L.

The density of a gas was found to be 19.1 g/L at 2.25 atm and 19.3°C. What is the molar mass of
the gas?
Answer:
Explanation:
Recall that the density of a gas is its mass to volume ratio,
ρ
=
m
V
. Therefore, if we can determine the mass of some volume of a gas, we will get its density. The density of an unknown gas can used to determine its molar mass and thereby assist in its identification. The ideal gas law, PV = nRT, provides us with a means of deriving such a mathematical formula to relate the density of a gas to its volume

Answer:
[tex]{\rm 1\; C_3H_8} + {\rm 5\; O_2} \to {3\; \rm CO_2} + {4\; \rm H_2O}[/tex].
Explanation:
[tex]{\rm ?\; C_3H_8} + {\rm ?\; O_2} \to {?\; \rm CO_2} + {?\; \rm H_2O}[/tex].
Among the four species in this reaction, [tex]\rm C_3H_8[/tex] is species with the largest number of atoms per molecule. Assume that the coefficient of this compound is [tex]1[/tex].
[tex]{\rm 1\; C_3H_8} + {\rm ?\; O_2} \to {?\; \rm CO_2} + {?\; \rm H_2O}[/tex].
Number of atoms on the left-hand side of the reaction:
[tex]\rm C[/tex]: [tex]1 \times 3 = 3[/tex].[tex]\rm H[/tex]: [tex]1 \times 8 = 8[/tex].[tex]\rm O[/tex]: not found yet.By the conservation of atoms, the number of atoms on the right-hand side of the reaction should match those on the left-hand side. In this reaction, [tex]\rm CO_2[/tex] is the only product with carbon atoms, whereas [tex]\rm H_2O[/tex] is the only product with hydrogen atoms. These [tex]3[/tex] carbon atoms and [tex]8[/tex] hydrogen atoms would correspond to:
