Answer : The correct option is, Bases.

Explanation :

Acids : It is a substance that has ability of donating proton or hydrogen ion, $H^+$ .

Bases : It is a substance that has ability of donating hydroxide ion, $OH^-$ .

Salts : It is an ionic compound that contain positively charged ions and negatively charged ions. The salt is formed when an acid react with a base in equal proportions.

Neutral compound : It is a compound that is formed by the combination of strong acid and strong base or weak acid and weak base.

As per question, KOH and LiOH are the examples of bases because they have ability of donating hydroxide ion, $OH^-$ . KOH and LiOH are the strong base that are completely dissociate.

$KOH\rightarrow K^++OH^-$

$LiOH\rightarrow Li^++OH^-$

Hence, the correct option is, Bases.

A fixed quantity of gas fills a volume of 10.6 liters at 638 torr and 83 C. Find the volume it will occupy if the pressure is 10

sukhopar [10]

According to this formula:
(P1V1) / T1 = (P2V2) / T2

convert T from C° to Kelvin:
T1 = 83 + 273 = 356 K
T2= 96 + 273 = 369 K

convert P from torr to atm:
1 torr = 0.00131578947 atm
p1 = 0.839474 atm
P2 = 1.415789 atm
By substitution in the previous formula:
(0.839474 x 10.6 ) / (356) = ( 1.415789 x V2 ) / 369
So:
V2 = 6.5 L

2H2 + O2 --> 2 H2O + How many moles of oxygen is required to produce 13.3 moles of water?

LenKa [72]

Answer:

Explanation:

Let the number of moles of oxygen = x

2H2 + O2 --> 2 H2O

x 13.3

Since the balance number for oxygen is 1 and the balance number for water is 2, you must set up a proportion. (Those balance numbers represent the number of moles).

1/x = 2 / 13.3 Cross Multiply

2*x = 13.3 Divide both sides by 2

2x/2 = 13.3/2

x = 6.65

You need 6.65 moles of oxygen.

Usually potassium hydrogen phthalate is kept very pure. But Stu Dent thinks the bottle of potassium hydrogen phthalate has been

Ahat [919]

Answer:

1.784 g

Explanation:

The equation of the reaction is;

NaOH(aq) + KHC8H4O4(aq) --------> KNaC8H4O4(aq) + H2O(l)

Number of moles of NaOH reacted = 17.47/1000 * 0.5000 M

Number of moles of NaOH reacted =8.735 * 10^-3 moles

From the reaction equation;

1 mole of NaOH reacted with 1 mole of KHC8H4O4

Hence, 8.735 * 10^-3 moles of NaOH reacts with 8.735 * 10^-3 moles of KHP.

So,

Mass of KHP reacted = 8.735 * 10^-3 moles * 204.2 g/mol = 1.784 g
