Answer:
HCl
Explanation:
Phosgene (COCl₂) on reaction with moisture in lungs converts into Carbon dioxide and hydrochloric acid.
COCl₂ + 2 H₂O → CO₂ + 2 HCl
The HCl produced in lungs causes problems. It reacts with alveoli proteins resulting in suffocation, coughing, eyes and throat irritation and difficulty in breathing.
Answer:
A solution that contains a system at equilibrium is the one in which there is no change in color
Explanation:
If the color of the solution changes slowly it means that the equilibrium shifts towards the right. This happens when we add the reactant and the equilibria move towards the right that is away form the reactant increasing the product formation. But when there is no change in color it means the reaction is constant and there is a state where the concentrations of reactant and product are not changing and are constant.
Hence, the solution in which the color is not changing is at equilibrium.
In addition to protons and neutrons, all atoms have electrons, negatively charged particles that move around in the space surrounding the positively-charged nuclear core. But unlike protons, the number of electrons can and does change without affecting the kind of element an atom is!
Answer:
172.23L
Explanation:
Data obtained from the question include:
V1 (initial volume) = 200 L
P1 (initial pressure) = 0.94 atm
T1 (initial temperature) = 25°C = 25 + 273 = 298K
P2 (final pressure) = 1atm
T2 (final temperature) = 0°C = 0 + 273 = 273K
V2 (final volume) =?
Using the general gas equation P1V1/T1 = P2V2/T2, the final volume of the container can be obtain as follow:
P1V1/T1 = P2V2/T2
0.94 x 200/298 = 1 x V2/273
Cross multiply to express in linear form as shown below:
298 x V2 = 0.94 x 200 x 273
Divide both side by 298
V2 = (0.94 x 200 x 273)/298
V2 = 172.23L
The new volume of the container is 172.23L
