Volume in liters of Carbon dioxide : 0.672
Further explanationReaction(combustion of butane-C₄H₁₀)
2C₄H₁₀+13O₂⇒8CO₂+10H₂O
mol butane (MW=58,12 g/mol) :
[tex]\tt \dfrac{0.85}{58,12}=0.015[/tex]
mol CO₂ : mol C₄H₁₀ = 8 : 4, so mol CO₂ :

How many moles are there in a 122 gram sample of nickel (Ni)?
7.16 x 103 moles
6.22 mol
2.08 mol
0.481 mol
The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.
Nickel:
The atomic number of nickel is 28.The symbol of nickel is Ni.Density of a nickel 8.908 g/cm3.It is a d block element.It belongs to group 10 and period 4.It is also called transition metal.It is a metal and is located between groups 2 and 3.Mass of nickel given: 122 grams.
Atomic mass of nickel: 58.71 g mol
Number of moles = Mass / molar mass
= 122/ 58.71
= 2.078
= 2.08 moles.
The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.

why carbon is a basic thing to classify as organic and inorganic compounds?
Answer:
To answer, all living organisms contain carbon-based compounds, which classifies them organic.
Simply, carbon dioxide, is an example of an inorganic compound since it does not contain both carbon and hydrogen. Alternatively, one molecule of carbon dioxide contains one atom of carbon and two atoms of oxygen.

Which of the following is true about waves?
A.
They are always visible.
B.
They always move matter.
C.
They carry energy.
D.
They can only travel though outer space.
Answer:
c. they carry energy is the answer
Answer:
C. they carry energy
Explanation:
Energy can be carried from one place to another by waves, including water, light, and sound waves. Waves are oscillating disturbances that travel through but do not move matter.
Infrared radiation escaping from hot coals is an example of invisible waves carrying energy. This energy can be felt as heat.

The force of attraction between one polar molecule and another polar molecule is
Answer:
Dipole-dipole forces
Explanation:
A polar compound is that compound which contains atoms that have a difference in charges i.e electrostatic attraction occurs between its constituent atoms. Polar molecules are attracted to other polar molecules with opposite charges and her held together with the aid of certain forces
The attractive force between the negative part of a polar molecule (-) and the positive part of another polar molecule (+) is called DIPOLE-DIPOLE FORCES. This dipole-dipole force gets stronger with an increasing polarity of the molecules involved.

Describe, on the molecular level, why my glasses get fogged up when I wear my face mask (so dang annoying). Be sure to use these terms: -decreased kinetic energy -surface -attraction
Answer:
When you are in a cool place and exhale into your mask, the mask blocks and re-directs some of your breath up toward the top edge of the mask and under your glasses. ... When the warm breath hits the cool lens, the water in the breath condenses causing your lenses to fog up.
Two individual atoms of the same element are slightly different. One has one more proton than it has electrons. The other has one more electron than it has protons. These atoms are both
ions
isotopes
freons
xenons
phlogistons
Answer:
ions
Explanation:
Individual atoms of the same element but having slightly different number of protons and electrons are called ions.
Ion is a charged particle.
An atom is made up of three fundamental subatomic particles. Protons are the positively charged particles Electrons are the negatively charged particles Neutrons do not carry any charges.When the number of protons > electrons the body is positively charged.
When the number of electrons > protons the body is negatively charged.
Charged particles are called ions.

Answer:
B) 6 Newtons
Explanation:
Applied Force = 10 N
Resistive Frictional Force = 4 N
As we know that frictional forces always act in the opposite of the relative motion [force], and that opposite forces always subtract.
Hence,
The Net Force acting on the block = 10 N -4 N = 6 Newtons

At 303 K, the volume of a gas is 30.0 ml. At constant pressure, what is the new
volume of the gas if the temperature is decreased to 283K?
Answer:
V₂ = 28 mL
Explanation:
Given data:
Initial temperature = 303 K
Initial volume = 30.0 mL
Final temperature = 283 K
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 30.0 mL × 283 K /303 K
V₂ = 8490 mL.K / 303 K
V₂ = 28 mL
