Answer:disagree. Temperature increases, water expands.
Explanation:
Answer:
400 becuase NAOH AND TJE NAOH ARE THE same
Explanation:
We first need to find the number of moles of gas in the container
PV = nRT
where;
P - pressure - 2.87 atm x 101 325 Pa/atm = 290 802.75 Pa
V - volume - 5.29 x 10⁻³ m³
n - number of moles
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 230 K
substituting these values in the equation
290 802.75 Pa x 5.29 x 10⁻³ m³ = n x 8.314 Jmol⁻¹K⁻¹ x 230 K
n = 0.804 mol
the molar mass = mass present / number of moles
molar mass of gas = 56.75 g / 0.804 mol
therefore molar mass is 70.6 g/mol
I am not sure about my answer, but I think that it's density allows it to fall to the ground/floor.
Explanation:
The net ionic equation of a reaction is obtained from the complete ionic equation after removing the spectator ions.
The balanced chemical equation for the reaction of sodium bicarbonate with acetic acid is shown below:
