Answer:
Hello my friend! The correct answer is "The process shown in the image can best be described as a rapid chemical reaction where gas is released"
Explanation:
Most antacid products uses Sodium bicarbonate (NaHCO3). When placed in water, NaHCO3 reacts with acids very rapidly, releasing CO2, according to the chemical reaction below:
NaHCO3 + HCl → NaCl + H2O + CO2
Answer:
Brass is an alloy, and either a "solid solution".
Alloys in general may be solid solutions or they simply be mixtures

We assume that the given gas, NO2, is an ideal gas such that we will be able to use the equation,
n/V = P/RT
where n is the number of moles, V is volume, P is pressure, R is gas constant, and T is temperature in kelvin. Substituting the known values,
n/V = (1 atm) / (37 + 273)(0.0821 L.atm/mol.K)
n/V = 0.039 mol/L
Converting this to density by multiplying the value with the molar mass,
density = (0.039 mol/L) x (46 g/mol) = 1.8 g/L
