A experimental investigation
Answer:
Explanation: Ammonia (NH3) is produced by the reaction of nitrogen gas and hydrogen gas. ... How many grams of fluorine gas are needed to produce 100.00g of AlF3? ... How many molecules of CO2 gas can be produced of 156.24g of benzene, ... (a) If 16.74.g of Fe and 9.0 9 of H2O are allowed to react, how many grams of products.
Answer:
T₂ = 84.375 K
Explanation:
Given data:
Initial volume = 3.3 L
Initial pressure = 2000 torr
Initial temperature = 225 K
Final temperature = ?
Final volume = 2.75 L
Final pressure = 900 torr
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₁V₁/T₁ = P₂V₂/T₂
T₂ = P₂V₂ T₁ /P₁V₁
T₂ = 900 torr× 2.75 L× 225 K / 2000 torr×3.3 L
T₂ = 556875 K/ 6600
T₂ = 84.375 K
Answer:
Generally, we know that ionic compounds are formed by reaction of metals and non metals and non metals form a covalent or non ionic bonds.
<u>IONIC COMPOUDS</u>
- Iron and chlorine (FeCl2) , ( FeCl3)
- Chlorine and Lithium (LiCl)
- oxygen and calcium ( CaO)
- Potassium and Sulphur ( K2S)
<u>NON IONIC COMPOUNDS</u>
- Potassium and Calcium (covalent bond)
- Sulphur and Bromine (covalent bond)
