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

For the reaction at equilibrium: 2 NO(g) + O2(g) → 2 NO2(g) Which change will increase the amount of NO2(g)? a. Remove NO gas b.

MAVERICK [17]

Answer:

b. Add NO gas

Explanation:

According with Le Chatelier´s principle, when a reactant is added the equilibrium is displaced to the product(s), to achieve the equilibrium again. Therefore, if NO is added in the reaction, it will be produced more of NO2(g).

A column is packed with 0.5 g of a strongly acidic ion exchange resin in H+ form. A 1.0 M NaCl solution is passed through the co

Lena [83]

Answer:

The correct answer is 17 meq/g

Explanation:

Ion exchange capacity (IEC) express the total of active sites of a resin in which ions are attached because the greater molecular weight.

The exchange Reaction can be represented as

R-H $R-H^{+} + Na^{+} + Cl^{-} -> R-Na^{+} + HCl_{aq}$

The IEC value (in meq/g) is determinated by using the next equation:

IEC=[(mL of NaOH)*(M of NaOH)]/mass of resin

IEC [(17 mL)*(0.5 M)/0.5]= 17 meq/g
