The solution would not be able to conduct electricity because there would not be free flowing ions in the solution for electricity to travel through.
Answer:
Lithium is a naturally occurring alkali metal, which living organisms ingest from dietary sources and which is also present in trace amounts in the human body. In much higher concentrations, lithium is effective as a medication for mania and mood swings including manic depressive disorders
Answer:
9.89 x 10²³ molecules H₂S
Explanation:
To find the molecules of H₂S, you need to (1) convert grams S to moles S (via the atomic mass of sulfur), then (2) convert moles S to moles H₂S (via the mole-to-mole ratio from equation coefficients), and then (3) convert moles H₂S to molecules H₂S (via Avogadro's Number). It is important to arrange the ratios/conversions in a way that allows for the cancellation of units. The final answer should have 3 sig figs to match the sig figs of the given value.
Atomic Mass (S): 32.065 g/mol
2 H₂S(s) + SO₂(g) -----> 3 S(s) + 2 H₂O(l)
Avogadro's Number:
6.022 x 10²³ molecules = 1 mole
79.0 g S 1 mole 2 moles H₂S 6.022 x 10²³ molecules
--------------- x --------------- x ---------------------- x ------------------------------------- =
32.065 g 3 moles S 1 mole
= 9.89 x 10²³ molecules H₂S
The paper in the straw makes the soda fizz.
Answer:
Explanation:
There are empirical formula calculators on the search engine that starts with G (This word is blocked by Brainly) and if you really need to use it, there's an option you can choose. However, I will try to explain this.
C = 65.4
H = 5.5
O = 29.1
We first need to divide the percentages by their molar mass.
65.4/12.01 = 5.44
5.5/1.008 = 5.46
29.1/16 = 1.8
We then need to divide these numbers by the smallest number we obtained.
1.8 is smaller than 5.46 and 5.46, so we would divide all three numbers with 1.8.
5.44/1.8 = 3
5.46/1.8 = 3
1.8/1.8 = 1
This means that there are 3 atoms of C and H and 1 atom of O, giving us the empirical formula of .
