The ostrich runs 21 N then goes back by 25 S
The displacement is -4 S
21 - 25 = -4
Solution :
It is given that dilute hydrochloric acid is titrated with sodium carbonate solution.
of a 0.100 of hydrocholric acid is used.
Thus, 10 mL of the 0.1 molar dilute hydrochloric acid is titrated with 16.2 mL of Sodium carbonate solution.
The equation would be :
Now we know that that the
Molarity =
For hydrochloric acid solution,
∴ n = 0.01 moles.
Now for one mole of , two moles of HCl acid is used.
For one mole of HCl, one-half mole of is required.
Therefore, for 0.01 mole of HCl, we require 0.005 mole of .
Hence, 0.01 mole of hydrochloric acid and 0.005 mole of solution is used.
The color turns red when methyl orange indicator is used in HCl acid.
Answer:
it will change
Explanation:
if temperature of room is hot it doesn't freeze.
if temperature of room is cold it freezes
Answer:
In order to take steps by humans for controlling the change in climate.
Explanation:
It is important that scientist find out the change which occurs in the climate with the passage of time by performing experiments and also repeat the experiments in order to verify their findings. Due to these experiments, scientists also find out the reasons behind of climate change which enable us to take steps in preventing the change that occurs in the environment. it is also important for scientists to be able to explain how they know that climate has changed over time in order to explain that he is not assuming or making predictions, he has to provide evidence for his statement which is only be possible through experiments.
