The balanced equation would be:
2K+ MgBr2——> 2KBr+ Mg
So we’d need 25.6(12.8*2) moles of potassium.
Answer:
The pressure of the gas is kept constant. If the Kelvin temperature of the gas is doubled, the volume of the gas is. O 1.
Answer:
The Rf value of the compound is 0.33
Explanation:
Rf value is known as the retention factor value. It is commonly used in paper chromatography and thin layer chromatography for comparing and analyzing different substances. The retention factor (Rf) value is the ratio of the distance moved by a substance from the origin to the distance moved by the solvent front from the origin. The Rf value ranges from 0 to 1.
Rf = Distance the substance moved / Distance the solvent front moved
From the question,
Distance the substance (compound) moved = 20 millimeters
Distance the solvent front moved = 60 millimeters
Hence,
Rf = 20 millimeters / 60 millimeters
Rf = 0.33
Hence, the Rf value of the compound is 0.33.
To be effective, collisions between atoms must occur with the proper orientation and also the proper amount of energy.
<h3>What is the loss of kinetic energy due to the collision?</h3>
An inelastic collision is a collision in which there is a loss of kinetic energy. While the momentum of the system is conserved in an inelastic collision, the kinetic energy is not. This is because some kinetic energy has been transferred to something else.
In this case, is necessary have energy to be effective, so collisions between atoms must occur with the proper orientation.
