Hydrogen bromide is found in volcanic gas. What is the chemical formula for<br> this compound?
ruslelena [56]

Answer:

Hydrogen bromide, anhydrous appears as a colorless gas with a pungent irritating odor. Corrosive. Heavier than air. Prolonged exposure to fire or intense heat may result in the violent rupture and rocketing of the container. Long-term exposure to low concentrations or short-term exposure to high concentrations can result in adverse health effects from inhalation. Used to make other chemicals and as a catalyst in the manufacture of chemicals. Rate of onset: Immediate Persistence: Minutes to hours Odor threshold: 2 ppm Source/use/other hazard: Chemical manufacturing industry; very corrosive.

dybincka [34]

answer:

This allows us to tell alkenes apart from alkanes using a simple chemical test. Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot.

Determine the heat of reaction for the process TiO2(s) + 4HCl(g) TiCl4(l) + 2H2(g) + O2(g) using the information given below: Ti
Aleks [24]

Answer : The heat of reaction for the process is, 1374.7 kJ

Explanation :

According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.

The main chemical reaction is,

TiO_2(s)+4HCl(g)\rightarrow TiCl_4(l)+2H_2(g)+O_2(g)    \Delta H_{rxn}=?

The intermediate balanced chemical reaction will be,

(1) Ti(s)+O_2(g)\rightarrow TiO_2(s)     \Delta H_1=-939.7kJ

(2) 2HCl(g)\rightarrow H_2(g)+Cl_2(g)    \Delta H_2=-184.6kJ

(3) Ti(s)+2Cl_2(g)\rightarrow TiCl_4(l)    \Delta H_3=-804.2kJ

We reversing reaction 1, 3 and multiplying reaction 2 by 2 and then adding all the equations, we get :

(1) TiO_2(s)\rightarrow Ti(s)+O_2(g)     \Delta H_1=939.7kJ

(2) 4HCl(g)\rightarrow 2H_2(g)+2Cl_2(g)    \Delta H_2=2\times (-184.6kJ)=-369.2kJ

(3) TiCl_4(l)\rightarrow Ti(s)+2Cl_2(g)    \Delta H_3=804.2kJ

The expression for heat of reaction for the process is:

\Delta H_{rxn}=\Delta H_1+\Delta H_2+\Delta H_3

\Delta H_{rxn}=(939.7kJ)+(-369.2kJ)+(804.2kJ)

\Delta H_{rxn}=1374.7kJ

Therefore, the heat of reaction for the process is, 1374.7 kJ
