There are 3 aroma.
There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H2O. So, each molecule of water contains *3* atoms.
Answer:
The correct answer is B: 125 Nm
Explanation:
If an applied force causes rotation from upward to downward direction than the torque is clockwise and is called as negative clockwise torque. Minus sign represents the direction of the torque. SI unit of torque is Nm.
Given data:
Force = 25 N
r = 5.0 m
Formula:
Torque = r x F
= 5.0 m X 25 N
= 125 Nm
The clockwise torque is 125 Nm ( i.e -125 Nm. Here minus sign suggests that the torque is clockwise)
Explanation:
Chemical equilibrium is the reaction state where the rate of reactants reacting is equal to rate of products deteriorating.
1. Adding benzoate ions to the mentioned equation will shift the equilibrium towards reactant side making more benzoic acid.
2. Adding NaOH to remove hydrogen ions will make the benzoic acid ionize more and hence shift the equilibrium towards products.
3. Adding benzoic acid more will shift the equilibrium towards products.
4. Increasing the hydrogen ion concentration will shift the equilibrium towards reactant, thereby crystalizing the benzoic acid.
5. Cooling the solution will also shift the equilibrium towards reactant side making effective crystals.
