Answer: option <span>D. be given a positive charge produced by the movement of electrons to the other end of the ball.
</span>
Explanation:
This phenomenon is called electrostatic induction.
The excess of negative charge on the end of the rod will repel the electrons on the side of the pith ball that have been approached to it.
Then the electrons on the pith ball will move far away from this end with it will be left an excess of positive charge.
In this way the rod has induced that the ball acquires a positive charge on one end and a negative charge on the other end.

Answer:
The answer to your question is HCl + NaOH ⇒ NaCl + H₂O
Explanation:
Data
Double displacement reaction
Balanced chemical reaction
HCl + NaOH ⇒ NaCl + H₂O
Reactants Elements Products
1 Chlorine (Cl) 1
1 Sodium (Na) 1
2 Hydrogen (H) 2
1 Oxygen (0) 1
As we can see, the reaction is balanced and the coefficients of all reactants and products are 1, but the number is not written in a balanced reaction.
Answer:
a. Oxygen is the limiting reagent. 
b.
%
Explanation:
Hello,
a. Limiting reagent and sulfur trioxide's theoretical yield.
At first, we must compute the involved moles for both sulfur dioxide's and oxygen's as follows, considering the volumes in liters and the pressure in atm of 50.0mmHg*1atm/760mmHg=0.0658atm:

Afterwards, by considering the properly balanced chemical reaction:

We compute the oxygen's moles that completely reacts with the previously computed
moles of
as follows:

That result let us know that the oxygen is the limiting reagent since just
moles are available in comparison with the
moles that completely would react with
moles of
.
Now, to compute the theoretical yield of sulfur trioxide, we apply the following stoichiometric relationship:

b. Percent yield.
At first, we must compute the collected (real) moles of sulfur trioxide:

Finally, we compute the percent yield:
%

Best regards.
Answer : The molarity of a solution is, 4.88 M
Explanation : Given,
Mass of
= 325.4 g
Volume of solution = 500.0 mL
Molar mass of
= 133.34 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :

Now put all the given values in this formula, we get:

Therefore, the molarity of a solution is, 4.88 M
Gravitation Potential energy is converted into the Kinetic Energy, when it just reaches the ground. Some amount of energy is wasted in sound and heat energy when it strikes the ground. When the apple falls from the tree, it has some gravitational potential energy due to its height.
