Answer:
NaHCO 3 ( s ) + HC 2 H 3 O 2 ( aq ) ⟶NaHC2H3O2 + H2CO3 → H2O + CO2
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
Explanation:
Sodium bicarbonate and acetic acid reacts to form Sodium acetate and carbonic acid. The carbonic acid then produce carbon dioxide gas and water after undergoing decomposition.
Answer:
Argon gas
Explanation:
Argon is a chemical element. Its symbol is Ar. It is the noble gas which is odorless and colorless. It is one of the most abundant gas on the earth after oxygen and nitrogen.
Argon gas is most commonly used in the panes of the thermal windows. It has 34 percent lower thermal conductivity as compared to the air and so it is more comfortable to used instead of the air. It is an inert gas and does not react with other things. It is not harmful.
The mass is simply the product of volume and density. But
first, let us convert the volume into cm^3 (cm^3 = mL):
volume = 2.5 cups * (240 mL/cup)
volume = 600 mL = 600cm^3
So the mass is:
mass = 600 cm^3 * (1 g / cm^3)
<span>mass = 600g</span>
B. I’m sorry if I’m wrong ! Wasn’t sure about this question .
Take 58.5 and divide that by 0.5, we get 117 grams of Sodium Iodide per liter
If you are looking for molarity. Then there are 149.88 grams in one mole of Sodium Iodide. We have 0.78 moles of sodium iodide. Divide that by 0.5 liters (also dm3)
0.78 / 0.5 = 1.56 M
