Answer:
7.57 *10^1 g
Explanation:
10.9 mol Li *6.941 g/1 mol = 75.6569 > 7.57 *10^1 g
Answer:
PET polymer or Polyethylene terephthalate is also known as Terylene. In the PET polymer, the ester linkage between the monomers is formed by the reaction of the OH group of ethylene diol (glycol) and the CO2H group of terephthalic acid.
In the family of polyester, PET is considered as the mostly used thermoplastic polymer resin.
It is used widely in clothing fibers, as liquid and food containers, and as a substance for engineering resins. In the United Kingdom it is known as terelyne, in the United States as Dacron, and in Russia as Lavsan.
Graph B because that graph shows negative acceleration due to velocity decreasing.
//Hope I helped :)//
Answer:
The false statement is B.
Explanation:
When the temperature in a reaction increases, the rate of this reaction increases.
It means that it would be more probably to each molecule in the system collides but that does not mean that the reaction will happen faster because there is other factors that affect the velocity of the reaction, such as concentration of reactants, presence of catalyst, and activation energy.
Also, the nature itself of the reaction can affect the velocity, due to some of chemistry reactions occur instantaneously without increasing the temperature and in the case you increase the temperature the reaction will not occur quickly.
On the other hand, the size of the particle will affect the rate due to smaller particles are able to move faster than larger ones under high Temperature.
Answer:
The equilibrium will remain at the same conditions because there is no effect and difference in the partial pressure which in turn affect the equilibrium state.
Explanation:
- As Nitrogen is an inert gas therefore it will not react with either the reactants or products.
- Also as the addition is being made by maintaining the volume of flask as constant, thus there will be no difference in the partial pressure of the individual components of the mixture by addition of the Nitrogen gas.
- An increase in pressure is observed but the effect is not aiding or retreating the equilibrium conditions
