Ordinary window, and bottle glass is homogeneous mixture. A lot of design and special art-formed glass peaces are heterogenous mixture. Like glass marble with swirls of color in it is heterogeneous mixture.) SUGAR Table sugar is a compound.
Answer:
It becomes negatively charged
Explanation:
An atom of chlorine having equal number of protons and electrons is neutral. The protons are the positively charged particles located in the nucleus of an atom. Electrons are negatively charged particles located outside the nucleus.
When the number of electrons and protons are the same, such an atom is neutral.
If the number of protons is more, the atom becomes positively charged.
In this case, the atom adds or gains an electron making the number of electrons to go from 17 to 18. This is more than the number of protons which are 17 by 1. The charge on the atom is therefore -1.
Answer:
1.133 kPa is the average pressure exerted by the molecules on the walls of the container.
Explanation:
Side of the cubic box = s = 20.0 cm
Volume of the box ,V= 

Root mean square speed of the of helium molecule : 200m/s
The formula used for root mean square speed is:

where,
= root mean square speed
k = Boltzmann’s constant = 
T = temperature = 370 K
M = mass helium = 
= Avogadro’s number = 

Moles of helium gas = n
Number of helium molecules = N =
N = 
Ideal gas equation:
PV = nRT
Substitution of values of T and n from above :






(1 Pa = 0.001 kPa)
1.133 kPa is the average pressure exerted by the molecules on the walls of the container.
