Air, glass and water are common materials that are very good at transmitting light. They are transparent because light is transmitted with very little absorption. Translucent materials transmit some light but are not completely clear.

6832 J of heat energy is applied to 5.9 mol of water. If the original temperature of the water was 18.60C, the final temperature

sineoko [7]

Answer: The final temperature of the water will be $34.0^0C$

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

$Q=m\times c\times \Delta T$

Q = Heat absorbed= $6832$ Joules

m= mass of water = $5.9mol\times 18g/mol=106.2g$

c = specific heat capacity = $4.184J/g^0C$

Initial temperature of the water = $T_i$ = $18.6^0C$

Final temperature of the water = $T_f$ = ?

Putting in the values, we get:

$6832=106.2\times 4.184\times (T_f-18.6)$

$T_f=34.0^0C$

The final temperature of the water will be $34.0^0C$

Which species is classified as a Arrenhius base? 1. CH3OH 2. LiOH 3. PO43- 4. CO32-

Otrada [13]

Answer:

2. LiOH

Explanation:

An Arrhenius base is a substance or chemical compound which increases the number of OH- ions when added in water.

LiOH or lithium hydroxide is one of the strong Arrhenius base as it ionizes completely or near-completely in solution. When LiOH is added to water , it dissociates into lithium (Li+) and hydroxide (OH−) ions.

Hence, the correct answer is 2. LiOH.
