The chemical contractor has to retrieve the chemical and a identification analysis would have to be conducted
The empirical formula is obtained by calculating the mole ratios of the atoms in the elements.
The number of moles =mass/ R.A.M
For hydrogen, no. of moles=8/1=8
For oxygen, no. Of moles=64/16=4
The tabular solution is attached.
Answer:
Option (B) It separates the hydrogen ion (H+) from the chlorine ion (Cl–).
Explanation:
The reaction above simply illustrate the dissociation of HCl when dissolve is water.
When HCl is dissolved in H2O, it will separate into the hydrogen ion, H+ and chloride ion Cl- as shown below
HCl —> H+ + Cl-
The water help to separate the H+ from the Cl-
Answer:
A nucleus is a positive charge
Explanation:
A nucleus is made up of protons and neutrons. Protons have a positive charge and neutrons have a neutral charge.
<span>a. What is the empirical formula of the gas? In this case, the empirical formula is the same as the molecular formula
</span>
An empirical formula is a formula that gives the proportions of the elements present in a certain compound however it does not give the actual numbers or the arrangement of the atoms. To determine this, we do as follows:
H = (1.69)(.05) = 0.08 g ( 1 mol / 1.01 g ) = 0.0792 / 0.0792 = 1
F = (1.69)(.95) = 1.61 g ( 1 mol / 19 g ) = 0.0847 / 0.0792 = 1
The empirical formula would be HF.
<span>b. What is the molecular formula of the solid?
I bet there is a lacking information for the solid. We cannot determine the molecular formula with only the values given above. The closest would be the compound UF2O2.
</span><span>c. Write a balanced equation for the reaction between UF6 and H2O.
</span>2H2O + UF6 -> UF2O2 +4HF
