Answer:
Explanation:
When iron is heated in air it reacts with oxygen to form the compound iron oxide. Iron is a solid and oxygen is a gas.
The name of the acid that is formed when hydrogen sulfide is dissolved in water would be hydrosulfuric acid. It has the same chemical formula as hydrogen sulfide which is H2S. It is classified as a weak acid which partially ionizes into hydrogen sulfide ions and hydronium ions. It is a very toxic substance and is distinguished by its strong odor which is compared to an egg that is rotting. It can be found in high concentrations in the crust of the Earth, in volcanic emissions and in many fossil fuels. To produce this acid, the gas hydrogen sulfide is dissolved into the water. However, this acid is not produced since it does not have any industrial application.
Answer:
The Bismuth atom
Explanation:
it contains 83 atoms, 5 of which are valence electrons. These 5 electrons are accommodated in the 6s and 6p orbital.
Answer:
V₂ = 9.14 L
Explanation:
Given data:
Initial volume = 4.28 L
Initial pressure = 42.20 mmHg (42.20/760 = 0.056 atm)
Initial temperature = 10.24 °C (72 +273 = 283.24 K)
Final temperature = 213°C (213+273 = 486 K)
Final pressure = 4.56 KPa (4.56/101.325 = 0.045 atm)
Final volume = ?
Solution:
P₁V₁/T₁ = P₂V₂/T₂
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 0.056 atm × 4.28 L × 486 K / 283.24 K × 0.045 atm
V₂ = 116.48 atm .L. K / 12.75 K . atm
V₂ = 9.14 L
