Answer : The formic acid pressure is, 99 torr
Explanation :
The given chemical reaction is:
Initial pressure a 0 0
At time 't' (a-x) x x
According to the Dalton's law,
.........(1)
As we are given that:
Initial pressure = a = 220 torr
Now put the value of 'a' in equation 1, we get:
Thus, the formic acid pressure is, 99 torr
Answer:
Final pressure of the gas remaining in the first container is 3.5 atm
Explanation:
Since it is given that temperature is constant , we can apply -
PV=constant , where
P = Pressure of the gas
V = Volume of the container in which the gas is contained
Initially,
For container 1 -
= 4 atm
= 6 L
Finally,
For container 2 -
= 3 atm
= 1 L
For container 1 -
= ?
= 6 L
∴ = +
∴ 4×6 = (×6) +(3×1)
∴ = 3.5 atm
The density means that the mass divided by the volume with the formula: density = mass/volume. So volume=mass/density. Under same temperature, the volume=15.5/0.789=19.6 cm3=19.6 ml.
Answer:
Translation
Explanation:
Protein synthesis is the process of production of proteins in in the cells of living organisms. Transcription and Translation are the two main steps in the protein synthesis. The first step is completed in nucleus where mRNA is made using DNA as template. The second step i.e. translation occurs in the cytoplasm with the help of Ribosomes. The mRNA synthesized during transcription is pre-mRNA. After the processing it is assembled as mature RNA. After getting assembled the second step of protein synthesis viz. Translation begins in the cytoplasm.
C. Speed is how fast, velocity has direction and acceleration is a change in velocity.
