Answer:
K loses one electron to CI
Explanation:
The lewis electron dot notation shows only the chemical symbol of the element surrounded by dots to represent the valence electrons.
We have atom of K with one valence electrons
Cl with 7 valence electrons
For an electrostatic attraction to occur, both particles must be charged. To do this, one of the species must lose an electron, and the other gains it.
This will make both species attain a stable octet;
Hence, K will lose 1 electron and Cl will gain the electrons.
Answer:
Helum (He)g will escape faster
Explanation:
the phenomemenon can be explained by the Graham's law of diffusion.
Graham's law of difussion states that the rate of difussion is inversely proportional to the square root of the molecular mass,which means the gas with lower molecular mass will escape faster.
Helium gas has a molecular mass of 4 while Neon has a molecular mass of 10.
rate of diffusion of He/rate of difussion of Ne=√4/10=√0.4=0.63
It means He(g) will move 0.63 times faster than Ne(g) under the same condition
Various pieces of safety equipment are used in the lab to provide protection against injury. However, the lab safety equipment which is least likely to be used when proper eye goggles are being worn is the eye wash station. If this question has the same choices as the ones posted before, the answer is letter C. eye wash station.
