Answer: False

Explanation:

pH is defined as the negative logarithm of hydronium ion concentration present in the solution.

$pH=-log[H_3O^+]$

If the solution has low hydronium ion concentration than hydroxide ion concentration, the pH will be high and the solution will be basic. The pH range of basic solution is 7.1 to 14

If the solution has high hydronium ion concentration than hydroxide ion concentration, the pH will be low and the solution will be acidic. The pH range of acidic solution is 0 to 6.9.

The solution having pH equal to 7 is termed as neutral solution.

Thus the given statement is False.

If you dilute 19.0 mL of the stock solution to a final volume of 0.310 L , what will be the concentration of the diluted solutio

Dahasolnce [82]

Answer:

$M_2=0.613M_1$

Explanation:

$M_1$ = Concentration of stock solution

$M_2$ = Concentration of solution

$V_1$ = Volume of stock solution = 19 mL

$V_2$ = Volume of solution = 0.31 L= 310 mL

We have the relation

$M_1V_1=M_2V_2\\\Rightarrow M_2=\dfrac{M_1V_1}{V_2}\\\Rightarrow M_2=\dfrac{M_119}{310}\\\Rightarrow M_2=M_1\times\dfrac{19}{310}\\\Rightarrow M_2=0.613M_1$

$\boldsymbol{\therefore M_2=0.613M_1}$

The concentration of the diluted solution will be 0.613 times the concentration of the stock solution.

What force is causing The object to eventually stop moving

hichkok12 [17]

Answer:

Hey buddy, here is your answer. Hope it helps you.

Explanation:

The force stopping the object's motion might be an obvious one - the ground! Friction is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance). Even air causes friction.

How much sodium bicarbonate to raise alkalinity in pool.

almond37 [142]

Answer:

A rule of thumb is that 1.5 lbs. of baking soda per 10,000 gallons of water will raise alkalinity by about 10 ppm. If your pool's pH is tested below 7.2, add 3-4 pounds of baking soda. If you're new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount.
