Answer:
No.
Explanation:
No. There is 1 atom of Ca on the left and 2 Ca's on the right and 2 OH's on the left and 4 on the right.
The balanced equation is:
4OH- + 2Ca2+ ----> 2Ca(OH)2.
Answer:
c.
Explanation:
An Arrhenius acid increases the number of H+ ions in solution. They are the only positive ions in the solution.
<u>Answer:</u> The expression of equilibrium constant is
<u>Explanation:</u>
Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For a general chemical reaction:
The expression for is written as:
Concentration of pure solids and pure liquids are taken as 1 in the expression.
For the given chemical reaction:
The expression of for above equation follows:
Hence, the expression of equilibrium constant is
Answer:
Hexane
Explanation:
Generally, leucine is hydrophobic in nature and it has a carbon-hydrogen side chain. Therefore, it is not advisable to use an hydrophobic solvent because the leucine zipper would interact with both the opposite alpha helix and the solvent. This will ultimately hinder the dimer creation. Thus, the best solvent which is the least polar in the list is hexane.
Answer:
Between oxygen and selenium, oxygen is more electronegative because of more ionisation energy and small size
