Answer:
Explanation:
1. Please provide the enthalpy info - I will work on it with the info
2.
i) Reaction a should be modified to match the number of S in equation:
2S + 2O2 -> 2SO2 deltaH = -370kJ
ii) Reaction b should be written reversely to match the reactants of SO2:
2SO2 + O2 -> 2SO3 deltaH = 256kJ
iii) Adding the equations together:
2S + 3O2 -> 2SO3
iv) Enthalpy of the combined reaction = -370+256 = -114kJ
It is negative so the reaction is exothermic.
Answer:
The general equation for an exothermic reaction is: Reactants → Products + Energy.
A compound is a pure substance composed of two or more different atoms chemically bonded to one another. A compound can be destroyed by chemical means. It might be broken down into simpler compounds, into its elements or a combination of the two.
So there are basically five types of chemical reactions which have their general formulas.
They are:
1. Combination reaction
General formula : A+B = AB
2. Decomposition reaction
General formula: AB = A+B
3. Single displacement reaction
General formula: AB+C = CB + A
4. Double displacement reaction
General formula: AB+CD = CB+AD
5. Acid-base reaction
General formula: A+B = S+W
You should check and compare with examples.
Answer:
Physical and psychological dependence is high, and withdrawal symptoms include watery eyes, runny nose, loss of appetite, irritability, tremors, panic, abdominal cramps and diarrhea, nausea, chills, and sweating. Use of contaminated syringes/needles to inject drugs may result in serious blood borne infections such as HIV-AIDS and hepatitis.
