Answer:
34.23 grams H2O.
Explanation:
1 Mole of HCl produces 1 mole of water
So 1.9 moles producers 1.9 moles of water
= (2*1.008 + 16) * 1.9
= 18.016 * 1.9
= 34.23 grams H2O.
<span>A compound is a combination of elements chemically combined. Briefly explain why a beaker containing sand and water is a mixture although sand itself is a pure substance. Because it's a combination of two or more substances. ... Briefly explain why a compound has <span>characteristic properties</span></span>
Answer:
Neutrons
Explanation:
Isotopes are variations of an element that differ from the number of neutrons.
<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
A salt can be formed by an Alkali metal and A Halogen
