Answer:
6.76 moles.
Explanation:
2CO(g)+O2 (g) =2CO2(g)
When 2 CO mols were reacted with excess O2 then 2 mols of CO2 is created.
Therefore if 6.76 moles reacted, same number of CO2 will be created.
27 + (35,5 + 2* 16) * 3 = 229.5 g/mol
Answer:
There isn't any picture for me to see
have a good day :)
Explanation:
A transverse wave is a wave is a wave in which the particles in the medium oscillate in a direction that is perpendicular or at 90 degrees to the direction in which the wave propagates. Light waves or electromagnetic waves are a good example of transverse waves. When an electromagnetic wave propagates, the medium in which it propagates vibrates in a direction perpendicular to the direction of travel.
A longitudinal wave is a wave in which the particles of the medium oscillate in a direction parallel to the direction in which the wave is travelling. Sound waves are good examples of longitudinal waves. When sound propagates, the particles of the medium which it travels through will vibrate in the direction in which the wave is travelling.
Similarities
- Both transverse and longitudinal waves carry energy.
- Both transverse and longitudinal waves obey the wave equation.
- Both transverse and longitudinal waves show behavior such as refraction, reflection, absorption, diffraction, etc.
Differences
The main difference is that for longitudinal waves, the particles in the medium will vibrate in the direction of the wave and that for transverse waves, the motion of the particles in the medium is in a direction perpendicular to the direction of propagation of the wave.
Answer:
Moles
Explanation:
Mole is used to describes the amount of matter. The one mole of every substance have different mass, because every matter has different mass. The one mole of substance is equal to the molar mass of that substance.
The molar mass of substance is the mass in gram in one mole and it is represented by g/mol.
For example:
The molar mass of oxygen is 16 g/mol. If we take 16 g of oxygen we would say we taken one mole of oxygen. If we take 32 g of oxygen than it is describe as two mole of oxygen.
Consider the following reaction:
2H₂ + O₂ → 2H₂O
In this reaction two mole of hydrogen gas combine with one mole of oxygen and produce two moles of water.
