Some rocks contain carbonate minerals, and the acid test can be used to help identify them.
Answer:
1500kg/m^3
Explanation:
Formula:
d=m/v
Given:
m=1.5kg
v=1000cm^3
(The side length of a cube is always equal to the others)
Required:
d=?
Solution:
d=m/v
d=1.5kg/1000cm^3
d=1.5kg/0.001m^3
d=1500kg/m^3
Hope this helps ;) ❤❤❤
Answer:
Enzyme function is dependent on the three-dimensional structure or conformation of the enzyme
Explanation:
Enzyme are biological catalysts.
So they do alter the path of the reaction where the free energy change (or activation energy) is low then the non enzymatic pathway.
Thus the statement
Enzymes alter the free energy change (ΔG) of the reactions which they catalyze : True
It is known that for enzyme we function they need an optimum temperature and pH condition so the statement
Enzyme function is dependent on the pH and temperature of the reaction environment: true
This is also true that
Enzyme activity can be inhibited if the enzyme is bound by a noncompetitive inhibitor.
The false statement is : Enzyme function is dependent on the three-dimensional structure or conformation of the enzyme

Answer:
Balanced chemical equation:
AgCl + 2KCN → K[Ag(CN)₂] (aq) + KCl (aq)
Balanced chemical equation:
2Al + 6NaOH →2 Na₃AlO₃ + 3H₂
Explanation:
Chemical equation:
AgCl + KCN → K[Ag(CN)₂] (aq) + KCl (aq)
Balanced chemical equation:
AgCl + 2KCN → K[Ag(CN)₂] (aq) + KCl (aq)
Net ionic equation can not be written because all are present in aqueous form and no precipitation occur.
Chemical equation:
Al + NaOH → Na₃AlO₃ + H₂
Balanced chemical equation:
2Al + 6NaOH →2 Na₃AlO₃ + 3H₂
This is oxidation reduction reaction.
Hydrogen is reduced in this reaction. while aluminium is oxidized.
