Answer:
Substance K is hydrochloric acid and the process is neutralisation
Step-by-step explanation:
When you react hydrochloric acid and sodium carbonate, you produce sodium chloride, carbon dioxide and water
Where is the graph at? may you send a picture of it?
According to the kinetic molecular theory, the pressure of a gas in a container will increase if the "number of collisions with the container wall increases".
<u>Option: A</u>
<u>Explanation:</u>
Pressure is characterized as force acting by area per unit. It is triggered by gas molecules bombarding on the container walls. Kinetic molecular theory suggests that gases are made up of large numbers of small particles with continuous movement. Here there are elastic collisions between gas particles and between particles and container walls. There are no forces of attraction among them because of the large spaces between the gas particles. The gas temperature relies on the particle's average kinetic energy.
Answer:
Explanation:
The dilution formula is
s₁ v₁ = s₂ v₂
s₁ = .0043
v₁= 2 mL
v₂ = 100 mL
s₂ = ?
putting the values
.0043 x 2 = s₂ x 100
s₂ = .000086 = 86.0 x 10⁻⁶
Your answer is. C. CI2(g)+H2(g)
