Answer:
The amount of air (in grams) is required for an answer. The process is outlined below.
Explanation:
An example for 1 kg of air:
Energy = (specific heat)*(mass)*(temperature change)
Joules = (1.03J/g°C)*(1,000g)*(27°C - 9°C)
Joules = 18540J
Coversion: 1 Joule = 2.78E-07 kwh
Kwh to heat 1 kg of air from 9 to 27°C is 5.15E-03 kwh
Use the same process with the actual mass of air in the house. If you are given house dimensions, calculate the volume and multiply by the density of air to get grams air. (Remember to subtract the volume taken up by household items (e.g., beer cans).
Explanation:
colligative properties are properties that depend on the concentration of molecules or ions of the solute, but not on the identity of the solute. Colligative properties include lowering of vapour pressure, boiling point elevation, depression of the freezing point, and osmotic pressure
Noble gases having col:18
so the valence shell is D.8
<span>1. Gaseous acetylene (C2H2) reacts with oxygen gas to form gaseous carbon dioxide and gaseous water.
2. Chlorine gas reacts with aqueous potassium iodide to form solid iodine and aqueous potassium chloride.
3. Solid lithium oxide reacts with liquid water to form aqueous lithium hydroxide.
4. Gaseous carbon monoxide reacts with oxygen gas to form carbon dioxide gas.</span>
<span>Colloid is a type of mixture that scatters light and cannot be filtered. Colloids are heterogeneous mixtures with a particle size between that of the solutions and that of the suspensions: the size of the particles of a colloid is bigger than the molecules or ions of a solution and smaller than the particles of a suspension. Due to the small size of the particles in the colloids, the diluted colloids seem homogeneous, but those particles are big enough to produce the Tyndall effect, which is the dispersion of the light. Solutions do not show Tyndall effect.</span>
