It will form a tetraamminezinc sulphate and a blue solution will be formed...the reaction should be carried out in a fume chamber because a poisonous substance will be released to the atmosphere
The formula of the compound is XY. This means that the relation between the moles is 1: 1. One mole of X per one mole of Y.
From the information about the element X you can determine the number of moles of X (which is the same that the number of moles of Y).
# of moles of X = weigth of X / atomic mass of X = 17.15 g / 22.9 g/mol = 0.74598
Now the atomic mass of Y = weight of Y / # of moles of Y = 14.17 g / 0.74598 mol = 19 amu
Answer:
the partial pressure of Xe is 452.4 mmHg
Explanation:
Dalton's law of partial pressures says that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.
The partial pressures can be calculated with the molar fraction of the gas, in this case, Xe.
Molar fraction of Xe is calculated as follows:
Then, 0.29 is the molar fraction of Xe in the mixture of gases given.
To know the parcial pressure of Xe, we have to multiply the molar fraction by the total pressure:
Partial Pressure of Xe=1560mmHg*0.29
Partial Pressure of Xe=452.4mmHg

cleaning poultry equipment. This is done only at the beginning and ending of
your shift while cleaning should be done from time to time. Prior to
sanitization, all surfaces must be clean and thoroughly rinsed to remove any
detergent residue. Keep in mind that unclean surface cannot be sanitized. Sanitize
refers to reduction of unwanted microorganisms to levels considered safe from a

Answer:
The answer to your question is F = 28800 N
Explanation:
Data
q₁ = q₂ = 0.004 C
distance = r = 5 m
k = 9x 10⁹ C
Force = F
Formula
F = k q₁ q₂ / r²
-Substitution
F = (9 x 10⁹)(0.004)(0.004) / (5)²
-Simplification
F = 144000 / 25
-Result
F = 28800 N
-Conclusion
The force of repulsion between these balloons is 28800 N
