Answer: 3.45 L carbon dioxide are produced
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar volume}}=\frac{5.75L}{22.4L}=0.257moles[/tex]
[tex]C_3H_8+5O_2(g)\rightarrow 3CO_2+4H_2O[/tex]
According to stoichiometry :
5 moles of [tex]O_2[/tex] produce = 3 moles of [tex]CO_2[/tex]
Thus 0.257 moles of [tex]O_2[/tex] will produce=[tex]\frac{3}{5}\times 0.257=0.154moles[/tex] of [tex]CO_2[/tex]
Volume of [tex]CO_2=moles\times {\text {Molar volume}}=0.154moles\times 22.4L/mol=3.45[/tex]
Thus 3.45 L carbon dioxide are produced

Do you know this Ca(NO2)2 ? It's not calcium nitrate
Answer:
The answer is, in fact, Calcium Nitrate. I even looked it up to make sure, and according to PubChem, it is Calcium Nitrate. I suggest asking your teacher what this question is trying to ask because if it says it is not Calcium Nitrate, someone got it wrong.
Explanation:
The only other name I can think of, though, is Calcium Dinitrite.
based on the balanced equation: 2 K + Cl2 --> 2KCl what is the mole ratio of K to KCl
Answer:
2 : 2
Explanation:
The balanced chemical equation is given as:
2K + Cl₂ → 2KCl
From the balanced reaction equation, we can conclude that;
2 moles of K will react with 1 mole of Cl₂ 2 moles of K will produce 2 moles of KCl 1 mole of Cl₂ will produce 2 moles of KClTherefore, the mole ratio is 2:2 or 1:1 in the simplest form.

Balance the following Equation:
___Zn + ___HCl --> ___ZnCl2 + ___H2
50g of zinc are reacted with 50g of hydrogen chloride. What is the limiting reactant?
Group of answer choices
HCl
ZnCl2
Zn
H2
Answer:
HCl
Explanation:
Given data:
Mass of Zn = 50 g
Mass of HCl = 50 g
Limiting reactant = ?
Solution:
Chemical equation:
Zn + 2HCl → ZnCl₂ + H₂
Number of moles of Zn:
Number of moles = mass / molar mass
Number of moles = 50 g/ 65.38 g/mol
Number of moles = 0.76 mol
Number of moles of HCl:
Number of moles = mass / molar mass
Number of moles = 50 g/ 36.5 g/mol
Number of moles = 1.4 mol
Now we will compare the moles of Reactant with product.
Zn : ZnCl₂
1 : 1
0.76 : 0.76
Zn : H₂
1 : 1
0.76 : 0.76
HCl : ZnCl₂
2 : 1
1.4 : 1/2×1.4 = 0.7
HCl : H₂
2 : 1
1.4 : 1/2×1.4 = 0.7
Less number of moles of product are formed by HCl it will act limiting reactant.
How much Ag can be produced if one is given 64 g of Ag2O?
mass Ag = 59.5 g
Further explanationGiven
64 g of Ag2O
Required
Mass of Ag
Solution
Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
mass of Ag in Ag2O :
= ((2 x Ar Ag)/molar mass Ag2O )x mass Ag2O
[tex]\tt mass~Ag=\dfrac{2.Ar~Ag}{MW~Ag_2O}\times mass~Ag_2O[/tex]
Ar Ag : 107,8682 g/mol
MW Ag₂O = 231,735 g/mol
Input the value :
mass Ag = ( (2 x 107,8682 g/mol )/ 231.735) x 64 g
mass Ag = 59.5 g
Or we can use reaction
2Ag₂O ⇒ 4Ag + O₂
mol Ag₂O :
= 64 : 231.735
= 0.276
mol Ag :
= 4/2 x moles Ag₂O
= 4/2 x 0.276
= 0.552
mass Ag :
= 0.552 x 107,8682 g/mol
= 59.54 g

experiment was conducted the amount produced was 20.7 grams, the what is the percent
yield of the experiment?
Answer:
48.59%
Explanation:
theoretical yield = 42.6g
actual yield = 20.7g

How can we separate a homogenous mixture (a solution)? For example, how can we separate salt that has been dissolved in water?
Answer:
Well, to separate salt from water, you would stir the two together to create a homogenous mixture. Then you would boil the mixture; all the water would evaporate, leaving behind the salt
Explanation:
what is the theoretical yield (in mols) of magnesium when 1.1 x 102 mols of lithium reacts with excess magnesium chloride.
Explanation:
Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.
Nucleus Nucleus Atom 1 Atorn 2 Nucleus Nucleus Atom 3 Atom 4 Which two atoms are of elements in the same group in the periodic table?
Explanation:
The atoms of elements on the same period on the periodic table typically have the same number of valence electrons.
They have the same electronic configuration.
Valence electrons are electrons in the outermost shell of an atom.
The number of electrons in an atom is a good indicator of elements that might potentially belong to the same group.

Which statement best explains how the gases of the atmosphere affect the temperature of Earth?
A
The gases reflect all of the heat from the Sun, preventing it from reaching Earth's surface.
B
The gases absorb all of the heat from Earth's surface, preventing it from radiating into space.
С
The gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface.
D
The gases reflect some of the heat from Earth's surface, holding it away from the surface in space.
Answer: The answer is c
Explanation:
The gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface. Hence option C is correct.
What is atmosphere?Atmosphere is defined as a layer of gas that surrounds a planet and is kept there by the gravitational pull of the planetary body. The atmosphere of the earth shields its people by absorbing dangerous sun rays and preserving a constant temperature. It protects Earth from many space hazards and enables life there. As a result, it is crucial for regulating climate and a source of life on planet.
The majority of the infrared energy from the Sun is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds, creating the greenhouse effect. This causes the lower atmosphere and the Earth's surface to warm.
Thus, the gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface. Hence option C is correct.
