How much heat is required to change the temperature of a 15 g aluminum can with 100 g of water from 24.5°C to 55°C?
Assoli18 [71]
Heat capacity of aluminium = 0.900 J/g°C
While heat capacity of water = 4.186 J/g°C
Heat = heat gained by water + heat gained by aluminium 
Heat gained by water = 100 × 4.186 × 30.5 
                                   = 12767.3 Joules
Heat gained by aluminium = 15 × 0.9 × 30.5 
                                          = 411.75 Joules
Heat required = 13179.05 Joules or 13.179 kJoules

A gas at 127०C and 10.0 L expands to 20.0 L. What is the new temperature in Celcius? (HINT: You need to convert to Kelvins solve
Snowcat [4.5K]

Answer:

526.85K

Explanation:

Based on Charles's law, the volume of a gas is directly proportional to absolute temperature. The formrula is:

V₁ / T₁ = V₂ / T₂

<em>Where 1 represents the initial state and 2 the final state of the gas</em>

Using the values of the problem:

V₁ = 10.0L

T₁ = 127°C + 273.15K = 400.15K

V₂ = 20.0L

Thus, replacing in the formula:

10.0L / 400.15K = 20.0L / T₂

T₂ = 800K

In Celsius:

800K - 273.15 =<em> 526.85K</em>

A(n) ____________ releases H+ in water, therefore it must have one or more ___________ atoms as part of its structure.
shtirl [24]

An acid releases H^{+}  in water , therefore it must have one or more <u>hydrogen  </u>atoms as part of its structure .

Acids are chemical compounds that release hydrogen ions (H+) when placed in water. For example, when hydrogen chloride is placed in water, it releases its hydrogen ions and the solution becomes hydrochloric acid. Bases are chemical compounds that attract hydrogen atoms when they are placed in water.

A hydrogen ion is created when a hydrogen atom loses or gains an electron. A positively charged hydrogen ion (or proton) can readily combine with other particles and therefore is only seen isolated when it is in a gaseous state or a nearly particle-free space.
