Explanation:
When light with a continuous spectrum (emitted by a black body) passes through a cool transparent gas, dark lines are observed in the continuous spectrum.
Answer is dark lines
I did this in school and you should search the title in google and it will appear that what I did and it worked good luck
Answer:
34g
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
H2S + 2AgNO3 —> 2HNO3 + Ag2S
Next, we shall determine the number of mole of H2S required to react with 2 moles of AgNO3.
This is illustrated below:
From the balanced equation above,
We can see that 1 mole of H2S is required to react completely with 2 moles of AgNO3.
Finally, we shall convert 1 mole of H2S to grams. This is shown below:
Number of mole H2S = 1 mole
Molar mass of H2S = (2x1) + 32 = 34g/mol
Mass = number of mole x molar Mass
Mass of H2S = 1 x 34
Mass of H2S = 34g
Therefore, 34g of H2S is needed to react with 2 moles of AgNO3.
Answer:
This question is incomplete
Explanation:
This question is incomplete but the completed question is in the attachment below. To determine the net ionic equation, one must first write the complete equation which is shown below
LiNO₃ + NaC₂H₃O₂ ⇒ LiC₂H₃O₂ + NaNO₃
The ionic equation represented from the above equation will be
Li¹⁺ NO₃⁻ + Na¹⁺ C₂H₃O₂¹⁻ ⇒ Li¹⁺ C₂H₃O₂¹⁻ + Na¹⁺NO₃¹⁻
Because the resultant NaNO₃ formed is an ionic compound (which does not form a molecule), the correct option from the options provided is the first option
