307 g of an unknown mineral is heated to 98.7 °C and placed into a calorimeter that contains 72.4 g of water at 23.6 °C. The hea
RSB [31]

Answer:

0.138 J/g.K

Explanation:

According to the law of conservation of energy, the sum of the heat released bt he mineral and the heats absorbed by the water and the calorimeter is equal to zero.

Qm + Qw + Qc = 0

Qm = - Qw - Qc   [1]

The heat absorbed by the calorimeter can be calculated using the following expression.

Q = C . ΔT

where,

C is the heat capacity

ΔT is the change in temperature

The heat released by the mineral and the one absorbed by the water can be calculated using the following expression.

Q = c . m . ΔT

where,

c is the specific heat capacity

m is the mass

ΔT is the change in temperature

Replacing in [1],

Qm = -Qw - Qc\\c_{m}.m_{m}.\Delta T_{m}=-c_{w}.m_{w}.\Delta T_{w}-C_{c}.\Delta T_{c}\\c_{m}=\frac{-c_{w}.m_{w}.\Delta T_{w}-C_{c}.\Delta T_{c}}{m_{m}.\Delta T_{m}} \\c_{m}=\frac{-(4.18J/g.K).(72.4g).(305.4K-296.6K)-(15.7J/K).(305.4K-296.6K) }{(307g).(305.4K-371.7K)} \\c_{m}=0.138J/g.K

Smog usually forms from gound-level ozone and what other human-made pollutant?
Bingel [31]

This happens when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources chemically react in the presence of sunlight. Ozone at ground level is a harmful air pollutant, because of its effects on people and the environment, and it is the main ingredient in “smog."

Determine the name for aqueous H2CO3. carbonous acid dihydrogen carbonate carbonic acid hydrocarbonic acid hydrocarbide acid
BabaBlast [244]

The name for aqueous H_{2} CO_{3} is carbonic acid.

So, option C is correct one.

Binary hydrogen compounds with non metals may form H+ (proton) and an anion dissolved in water. The acidic solutions are named as if they were molecular acids , using the usual name for the compound itself , replacing hydrogen with hydro- and suffix -ide with ic. The word acid is then use.

The inorganic acid is an acid drive from one or more inorganic compounds. All inorganic acids form hydrogen ions and the conjugate base ions when dissolved in water.

Example: carbonic acid ( H_{2} CO_{3} )
