Answer:
The total number of moles of reactants consumed when 1.00 mole of CO₂ (g) is produced is 2 moles.
Explanation:
You have that the balanced reaction is:
C₃H₈ (g) + 5 O₂ (g) ⇒ 3 CO₂ (g) + 4 H₂O (l)
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of reactants and products participate in the reaction:
C₃H₈: 1 moleO₂: 5 molesCO₂: 3 molesH₂O: 4 molesThe rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:
a ⇒ b
c ⇒ x
So [tex]x=\frac{c*b}{a}[/tex]
where a, b and c are known values. In this case the rule of three is applied as follows: if by stoichiometry of the reaction 3 moles of CO₂ consume 1 mole of C₃H₈, then 1 mole of CO₂ how many moles of C₃H₈ will it consume?
[tex]moles of C_{3} H_{8} =\frac{1 mole of CO_{2} *1 mole of C_{3} H_{8} }{ 3moles of CO_{2}}[/tex]
moles of C₃H₈= 0.33
Applying again a new rule of three: if by stoichiometry of the reaction 3 moles of CO₂ consume 5 moles of O₂, then 1 mole of CO₂ how many moles of O₂ will it consume?
[tex]moles of O_{2} =\frac{1 mole of CO_{2} *5 moles of O_{2} }{ 3moles of CO_{2}}[/tex]
moles of O₂=1.67
The total number of moles of reactants consumed will be the sum of the consumed moles of C₃H₈ and the consumed moles of O₂:
0.33 moles + 1.67 moles=2 moles
The total number of moles of reactants consumed when 1.00 mole of CO₂ (g) is produced is 2 moles.
Can someone figure this out for me thank you
What are two ways that atoms of different elements are different?
Answer:Explanation:Protons and other subatomic particles will be discussed a little later. The atoms of different elements are different from each other because they have different numbers of protons. The graphic below illustrates this point by showing the atoms of two elements in the containers of oxygen and hydrogen.

Explanation:
How many moles are in 3.63 x 1023 atoms of Mn?
Answer:
0.603 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{3.63 \times {10}^{23} }{ 6.02 \times {10}^{23} } = \frac{3.63}{6.02} \\ = 0.60299...[/tex]
We have the final answer as
0.603 molesHope this helps you
What’s the meaning of low metabolism
Answer:
A person with a "low" (or slow) metabolism will burn fewer calories at rest and during activity and therefore has to eat less to avoid becoming overweight.
meaning of normal metabolism-Metabolism is the process by which your body converts what you eat and drink into energy. Even when you're at rest, your body needs energy for functions such as breathing, circulating blood and repairing cells. The energy your body uses for these basic functions is known as your basal metabolic rate.
A person with a low metabolism will burn fewer calories at rest and during activity and therefore has to eat less to avoid becoming overweight.
Signs of a slow metabolism
-You have gas.
-You crave sugar.
-You keep gaining weight.
-It's tough to lose weight.
-You always feel bloated.
-You have hypothyroidism.
-You easily develop cellulite.
-Your blood sugar is too high.

Which of the elements has the same Lewis dot structure as calcium (Ca)?
A.Barium (Ba)
B.Potassium (K)
C.Germanium (Ge)
D.Argon (Ar)
Answer:
[tex]\boxed {\boxed {\sf A. \ Barium (Ba)}}[/tex]
Explanation:
Lewis dot structures illustrate the valence electrons in an element.
Valence electrons are the outermost electrons in an atom that bond with other atoms by accepting or releasing electrons. The groups, or columns, of the Periodic Table have the same number of valence electrons.Calcium is in group 2.
The other elements in this group are:
Beryllium, Magnesium, Strontium, Barium, and RadiumSo, all these elements have the same lewis dot structures because they have the same number of valence electrons.
Based on the answer choices, choice A is correct.

A solution is saturated in CO2 gas and KNO3 at room temperature. What happens when the solution is warmed to 75°C?
solid KNO, precipitates out of the solution
gaseous CO2 bubbles out of the solution
solid KNO, precipitates out and gaseous CO2 bubbles out
nothing happens; both CO2 and KNO3 remain in solution
Answer:
gaseous CO2 bubbles out of the solution
Explanation:
We already know that the dissolution of a gas in water is exothermic. Hence, when the temperature of a solution containing a gas is increased, the solubility of the gas decreases and the gas bubbles out of the solution.
Similarly, the dissolution of KNO3 in water is endothermic. This implies that the solubility of the solid increases with increasing temperature.
Thus the solid becomes more soluble at 75°.
When the solution is warmed to 75°C ; ( B ) gaseous CO₂ bubbles out of the solution
When a solution is saturated with CO₂ ( gas ) and KNO₃ ( s ) has its temperature increased above the room temperature to about 75°C the solubility of the gas CO₂ will decrease, because the solubility of gas in a solution decreases with an increase in temperature while the solubility of a solid increases with increase in temperature.
Since the solubility of the gas decreases the gas will escape as bubbles ( CO₂ bubbles ).
Hence we can conclude that When the solution is warmed to 75°C ; ( B ) gaseous CO₂ bubbles out of the solution.

Answer:
The correct reaction is as follows:
2Mg + O2 → 2MgO
3. Synthesis
Explanation:
Chemical reactions are of different types depending on how they occur. One of these types is called SYNTHESIS OR COMBINATION REACTION. A synthesis reaction is that reaction in which two atoms of two elements are chemically combined to form a single molecule or compound. That is;
A + B → AB.
This is the case in this question where atoms of Magnesium (Mg) and oxygen (O) reacted to form a single compound of Magnesium oxide (MgO). Hence, it is said to be a SYNTHESIS REACTION.

Explanation:
The ingredients that are important for the production of plastics are natural gas and plant liquids. The correct options are c and d.
What is plastic?Polymers are the primary component of a wide variety of synthetic or semisynthetic materials known as plastics. Due to their versatility and importance to civilization, plastics are a very important material. This is due to the fact that plastics can be bent and molded into a variety of objects, from plates to phones.
Radiation is to blame for this becoming possible. People who manufacture plastics can heat polymers sufficiently to allow them to bend by employing radiation. They can then be formed into a variety of things when this occurs.
Plastics are made from natural gases and liquids obtained from plants.
Therefore, the correct options are c, natural gas, and d, plant liquids.

When an electron moves from a lower energy level to a higher energy level, the atom:
A. absorbs light
B. gives off light
C. becomes a new isotope
Answer:
A. absorbs light
Explanation:
For an electron to move from a lower energy level to a higher energy level, energy needs to be added to the atom.
In most cases this required energy will be light: The electron of the atom will absorb the energy of the light and move to a higher energy level.
When said electron comes back to the lower energy level, the atom will conversely give off light.
