Answer: The given statement is true.
Explanation:
According to the Dalton's law, total pressure of a mixture of gases that do not react with each other is equal to the partial pressure exerted by each gas.
The relationship is as follows.
![p_{total} = \sum_{i=1}^{n} p_{i}](https://tex.z-dn.net/?f=p_%7Btotal%7D%20%3D%20%5Csum_%7Bi%3D1%7D%5E%7Bn%7D%20p_%7Bi%7D)
or, ![p_{total} = p_{1} + p_{2} + p_{3} + p_{4} + ......... + p_{n}](https://tex.z-dn.net/?f=p_%7Btotal%7D%20%3D%20p_%7B1%7D%20%2B%20p_%7B2%7D%20%2B%20p_%7B3%7D%20%2B%20p_%7B4%7D%20%2B%20.........%20%2B%20p_%7Bn%7D)
where,
....... = partial pressure of individual gases present in the mixture
Also, relation between partial pressure and mole fraction is as follows.
![p_{i} = p_{total} \times x_{i}](https://tex.z-dn.net/?f=p_%7Bi%7D%20%3D%20p_%7Btotal%7D%20%5Ctimes%20x_%7Bi%7D)
where,
= mole fraction
Thus, we can conclude that the statement Dalton's law of partial pressures states that the total pressure exerted by a mixture of gases is the sum of the pressures exerted independently by each gas in the mixture, is true.
The chemical equation without coefficients is:
Ca + CO2 + O2 --------> Ca CO3
You can balance that equation by trial an error.
This is the chemical equation balanced:
2Ca + 2CO2 + O2 --------> 2Ca CO3
Count the atoms on each side to check the balance
Atom Left side right side
Ca 2 2
C 2 2
O 2*2 + 2 = 6 2*3 = 6
Then those are the coefficients:
a0 = 2
a1 = 2
a2 = 1
a3 = 2
Answer:
energy which a body possesses by virtue of being in motion
Explanation:
the work needed ro accelerate a body of given mass
Because when equilibrium is reached, the reaction is still occurring in both directions, it's just that rate(forward) =rate(reverse) so there is no net change in the concentrations of the reactants or products.
Alleles are inside a gene and genes are made up by alleles. Also, a gene is DNA, so the allele is like piece of DNA inside a gene<span>.
Hope this helps:)
