Explanation:
The given reaction equation is as follows.
So, rate constants for different reactants and products written as follows.
As per the reaction equation, the stoichiometric coefficients of reactants and products are as follows.
A = -2
B = -1
C = 1
Therefore,
Hence, 
= 
= 12.5 
Thus, we can conclude that 
and 
are 12.5 .
<u>Answer:</u> The formula of the compound formed between rubidium and fluorine is RbF
<u>Explanation:</u>
Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.
The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.
Rubidium is the 37th element of the periodic table having electronic configuration of 
This will loose 1 electron to form 
ion
Fluoride is the 9th element of the periodic table having electronic configuration of 
This will gain 1 electron to form 
ion
To form 
compound, 1 rubidium ion is needed to neutralize the charge on fluoride ion
The formation of the given compounds is shown in the image below.
Answer:
d. None of the above
Explanation:
Desalination is the process of removing some mineral salts from water or soil thereby making a water more fresh and the soil less filled with mineral salts. Salty water can be desalinated by doing away with their salts leaving behind a water that would be more suitable for certain needs. Desalinated water can be used domestically, industrially and also for agriculture.
Soils that have been desalinized can be more suitable to plant some special types of crops that would not thrive where some certain mineral salts occur in excess.
Desalination is an expensive process.
Water reclamation is the reuse of waste to serve new needs. It involves recycling of waste or polluted water into a more fresher water. Reclaimed water can also be used for agricultural, domestic and industrial purposes.
Desalination is a method that can be used to reclaim water. It is also an expensive process.
Desalination recharges aquifers: Desalination is an artifical process and would not add back to the ground water storage.
Desalination provides water suitable for drinking: water reclamation also provides suitable water for drinking.
Answer:
option c
enzymes are protein molecules that act as catalysts to speed up bio chemical reactions
Answer:
Li₂CO₃ ⇒ Li₂O + CO₂ is a decomposition reaction.
Explanation:
In a decomposition reaction, a single substance decomposes, producing two or more different substances. In other words, in this type of reaction two or more substances are formed from a compound. The atoms that form a compound separate to give the products according to the formula:
AB → A + B
It can occur spontaneously, or be aided by a catalyst, heat, or electrolysis.
In this case:
Li₂CO₃ ⇒ Li₂O + CO₂ It is a type of chemical reaction in which a single compound decomposes into two or more compounds. So it is a decomposition reaction.
