Answer:
Carbon dioxide is produced whenever an acid reacts with a carbonate. This makes carbon dioxide easy to make in the laboratory. Calcium carbonate and hydrochloric acid are usually used because they are cheap and easy to obtain. Carbon dioxide can be collected over water, as shown in the diagram.

Answer:
1.343 atm
Explanation:
We are given the following;
Pressure, p = ?
Volume v = 27 L
Mass of oxygen = 44.9 g
Temperature, T = 315 K
The formular relating all these variables is the equation;
PV = nRT
where R = gas constant = 0.08206 L atm / mole K
To obtain n, we use;
number of moles, n = Mass / molar mass = 44.9 / 32 = 1.403 moles
From the ideal gas equation;
P = nRT / V
P = 1.403 * 0.08206 * 315 / 27
P = 36.27 / 27 = 1.343 atm
384000000m
to change from m to km you just need to divide that give unit in Meters by 1000
which equals,
384000
so,
384000000 meters = 384000 kilometers
