Answer
A. It changes the rate, R
Explanation
When we change the concentration of the reactants in a chemical reaction, it affects the rate of reaction that happens in the process. Typically, the rate of reaction will decrease with time if the concentration of the reactants decreases because the reactants will be converted to products. Similarly, the rate of reaction will increase when the concentration of reactants are increased.
Answer:
The calculations is shown in the attached file.
Explanation:
- The concept of dipole moment is applied here. the size of the dipole moment is given by multiplying the size of the charge by the distance apart.
- For simpler molecules, the sizes of the dipole moments are approximately proportional to the difference between the electronegativities of the atoms. Dipole moments are usually measured in debyes (D).
Dipole moments (μ) = q x r
The detailed calculation is shown in the attachment.
They differ in the number of their neutrons. Hydrogen doesn’t contain neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have mass numbers of one, two, and three.
Answer: Wht is it
Explanation:
Let me know so I can help
The correct answer would be the second option. When the gibbs free energy of a system is negative and the electromotive force (EMF) of the system is positive then the reaction is to occur readily without any input of energy. With this, the reaction is said to be spontaneous. The higher the value of the EMF of a cell then it means the driving force for the reaction to occur is also high.
