When baking soda (NaHCO3) is heated, it decomposes, producing carbon dioxide, water, and sodium carbonate. The carbon dioxide is
11Alexandr11 [23.1K]

Answer:

mass of carbon-dioxide = 0.262 g

Explanation:

Firstly, write the chemical equation of the reaction and balance the equation accordingly.

2NaHCO3(aq) → CO2(g) + H2O(l) + Na2CO3(aq)

Calculate the molecular mass of  baking soda

molar mass of baking soda = 23 + 1 + 12 + 48 = 84 g

2 moles of baking soda = 2 × 84 = 168 g

molar mass of CO2 = 12 + 32 = 44 g

if  168 g of baking soda produces 44 g of carbon-dioxide

1 g of baking soda will produce ? grams of carbon-dioxide

cross multiply

mass of carbon-dioxide = 44/168

mass of carbon-dioxide = 0.2619047619

mass of carbon-dioxide = 0.262 g

Refer to aqueous solutions containing 1:1 mole ratios of the following pairs of substances. Assume all concentrations are 1 M.
LekaFEV [45]

Answer:

c) HCl and NaCl

Explanation:

Since all the solutions are on a 1:1 mole ratio the comparison is straight forward.

The lowest pH will be for solution c) which has a strong acid, HCl, which ionizes 100 % and the neutral salt NaCl (which is neutral since it is derived from the reaction of the strong acid HCl and the strong base NaOH).

Solutions a) and b) are buffers of  the weak base NH₃ and its conjugate acid NH₄⁺ and weak acid H₃PO₄ and its conjugate weak base NaH₂PO₄ respectively.

Solution c) is a basic solution being a mixture of the weak base NH₃ and the strong base NaOH

Solution e) is a mixture of a weak base NH₂ and weak acid HC₂H₃O₂
