Chemical system is at equilibrium<span> if both reactants and products are present in concentrations which have no further tendency to change with time. To determine whether or not a chemical system is at equilibrium the following things need to be taken into consideration:
1. If the system is open, the chemical system is 100% not in equilibrium. (</span><span>Equilibrium may only be obtained in a closed system).
2. If t</span><span>he forward and reverse </span>reactions are happening at equal rates, then the system is at <span>equilibrium.
3. If t</span>he products and reactants are present in equal concentrations, then the system is at <span>equilibrium.</span>

Answer:
The environment of space is lethal without appropriate protection: the greatest threat in the vacuum of space derives from the lack of oxygen and pressure, although temperature and radiation also pose risks. The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.
Answer:
Liquids in a form of mixture has less weight as compared to sum of all liquid's weight due to release of gases.
The combined weights of several liquids mixed in an open flask be less than the sum of all the weights of the liquids because when the reaction occurs new products are formed and also some gases which releases in the atmosphere.
These gases also contribute in the weight of the product so when it is released the weight of the mixture of liquids are less than the sum of the weights of all liquids so we can conclude that liquids in a form of mixture has less weight as compared to sum of all liquid's weight.
