Answer:
[tex]\huge\boxed{\sf 39\ L}[/tex]
Explanation:
In the reaction:
for 1 mol of propane, 3 moles of CO₂ are produced.
Volume of propane = 13 L
At STP,
1 mol of propane = 22.4 L/dm³ molar value
So,
Moles in 13 L of propane:
= volume / molar volume
= 13 / 22.4
= 0.58 mol
Since,
1 mol of propane = 3 moles of CO₂
0.58 mol of propane = 3 × 0.58 mol of CO₂
0.58 mol of propane = 1.74 mol of CO₂
Converting 1.74 mol of CO₂ into L:
[Multiply it by 22.4 L/mol]
= 1.74 mol × 22.4 L/mol
= 39 L

Answers
If a mixture is prepared by mixing 29.27 mL of the blue dye solution with 35.00 mL of the red dye solution and 14.73 mL of the yellow dye solution, the molar concentration of the blue dye in the mixture is
MB'=0.1189M
What is the molar concentration of the blue dye in the mixture?Generally, the equation for the moles is mathematically given as
Moles=Molarity *volume
Therefore
For Blue dye
MB=0.3523*25.27*1/1000ml
MB=8.90*10^{-3}
For red dye
MR=0.1017*35.27*1/1000ml
MR=3.55*10^{-3}
For yellow dye
MY=0.3523*14.73*1/1000ml
MY=2.27*10^{-3}
Where
Total volume is
T=25.27+35.ml+14.73
T=75ml
In conclusion, The molar conc of blue dye is

When light from one source, X, strikes a metal, electrons are ejected. When light from another source, Y, strikes the same metal, electrons are not ejected. Which best explains why this occurs? Light from source X has a higher intensity than light from source Y. Light from source X has a lower intensity than light from source Y. Photons of light from source X carry more energy than photons of light from source Y. Photons of light from source X carry less energy than photons of light from source Y.
Answers
Answer:
Photons of light from source X carry more energy than photons of light from source Y
Explanation:
According to Einstein's photoelectric equation, the kinetic energy of the emitted photoelectron depends on the energy of the incident photon and the work function of the metal.
For photoelectrons to be ejected from a metal surface, the energy of incident photon must be greater than the work function of the metal. If not, no electron is ejected.
The energy of photon X must be greater than the work function of the metal while the energy of photon Y is less than the work function of the metal. This brings us to the conclusion that the energy of photon X must be greater than that of photon Y.

1. Nuclear fusion
2. Radiation
3. Conduction
Answers
Answer:
Nuclear fusion, Conduction, Conduction, Radiation.
The Sun produces energy deep inside its core by fusing hydrogen atoms together to form heavier ones through nuclear fusion. Conduction and convection are used to move heat from the core to the surface.
Radiation is the electromagnetic transmission of heat energy through space. The majority of the electromagnetic radiation that the sun emits and that reaches the Earth is invisible. Only a tiny fraction is visible light. Light consists of waves of various frequencies.
When two objects with different surface temperatures come in contact with one another, conduction happens. Up until they reach the same temperature, heat moves from the warmer to the cooler object. Heat moves through a substance by conduction when molecules collide.
Thus the correct order is Nuclear fusion, Conduction, Conduction, and Radiation.

Static charges can be applied to neutral objects by friction, induction or conduction. What do all of these methods utilize to create this charge?
Protons
Electrons
Heat Energy
Magnetic domains
Answers
Answer:
Electrons
Explanation:
"Static charges" occur when the number of positive charge and negative charge are not equal. This can be applied to neutral objects by friction, induction and conduction with the help of "electrons."
In friction, the electrons are being transferred between the objects being rubbed together.
In conduction, the electrons are also being transferred from one object to another but not through rubbing; instead through direct contact.
In induction, the electrons are able to react immediately without the need for direct contact.
So, electrons are being utilized in these processes in order to create charge.

Answers
Answer:
0.0499 moles
Explanation:
56.08g => 1 mol
2.80g => y mol
Y = 2.80/56.08 = 0.0499 moles
A sample of calcium oxide (CaO) has a mass of 2.80 g. the molar mass of CaO is 56.08 g/mol. No. of moles of CaO this sample contain are 0.499.
What is mole concept?Avogadro's number is the number of units in one mole of any substance and equals to 6.02214076 × 10²³. The units can be electrons, atoms, ions, or molecules.
No. of moles is defined as a particular no. of particles that we can calculate with the help of Avogadro’s number.
Mass of a particular product is also find out by stoichiometry of a reaction as per the no. of mole given in the reaction.
No. of moles = Mass of compound ÷ Molar mass of compound
No. of moles = 2.80 ÷ 56.08 = 0.0499
Therefore, A sample of calcium oxide (CaO) has a mass of 2.80 g. the molar mass of CaO is 56.08 g/mol. No. of moles of CaO this sample contain are 0.499.
