Answer:
See explanation
Explanation:
Let us see what happens when each solution is mixed;
a) AlCl3(aq) + K3PO4(aq) ------> 3KCl(aq) + AlPO4(s)
A precipitate is formed here
b) RbCO3(aq) + NaCl(aq) -------> This is an impossible reaction hence no solid precipitate is formed here
c) MnCl2(aq) + Na2CO3(aq) → 2NaCl(aq) + MnCO3(s)
A precipitate is formed.
d) K2S(aq) + 2NH4Cl(aq) ------> 2KCl(aq) + (NH4)2S(aq)
No solid precipitate is formed
e) CaCl2(aq) + (NH4)2CO3(aq) → CaCO3(s) + 2NH4Cl(aq)
A solid precipitate is formed
Answer:
The correct answer is the activation energy for the reaction is lowered.
Explanation:
Enzymes are homogenous, thermolabile,biological catalyst which speed the rate of a reaction but itself remains unchanged throughout the reaction.
Enzyme basically reduces the energy barrier also called activation energy and interact with the transition state of the reaction in a complementary fashion.
Enzymes does not have any effect in the equilibrium of the reaction.
Answer:
1) C
2)A
3)D
Explanation:
London forces are common to all molecules, it results from momentary shifts in electron distribution in molecules. When molecules possess a permanent dipole, dipole-dipole interaction is the dominant intermolecular force. However, for compounds in which hydrogen is bonded to highly electronegative element, hydrogen bonding is important.
Heat death refers to the 2nd law of thermodynamics which states that entropy trends increases in an isolated system. Thus hypothesized that the universe would last for an amount of time enough until it reaches a state that all energy is equally distributed.
Answer:
89 mL of solution would contain the given amount of Al(NO₃)₃.
