The effect of baking powder solution on dilute hydrochloric acid solution

1 answer:

5 0

Baking powder solution has an effect on a diluted hydrochloric acid solution by causing the release of carbon dioxide from sodium bicarbonate, a component of baking soda.

One molecule of backing soda + one molecule of hydrochloric acid yields one molecule of sodium chloride (table salt) + one molecule of carbon dioxide + one molecule of water.

HCl + NaHCO₃=NaCl+H₂CO₃

However, carbonic acid is quite unstable:

H₂CO₃ = CO₂ + H₂O

HCl + NaHCO₃ = NaCl + H₂O (Water) + CO₂.

Effervescence, which is a fast bubble formation, is how liquid releases CO2.

Yeast converts glucose to ethanol and carbon dioxide during a process known as anaerobic fermentation. The chemical reaction is

Korolek [52]

Answer:

102g

Explanation:

To find the mass of ethanol formed, we first need to ensure that we have a balanced chemical equation. A balanced chemical equation is where the number of atoms of each element is the same on both sides of the equation (reactants and products). This is useful as only when a chemical equation is balanced, we can understand the relationship of the amount (moles) of reactant and products, or to put it simply, their relationship with one another.

In this case, the given equation is already balanced.

$\tex{C_6H_{12}O_6} \longrightarrow 2 \ C_2H_6O + 2 \ CO_2$

From the equation, the amount of ethanol produced is twice the amount of yeast present, or the same amount of carbon dioxide produced. Do note that amount refers to the number of moles here.

Mole= Mass ÷Mr

Mass= Mole ×Mr

Method 1: using the mass of glucose

Mr of glucose

= 6(12) +12(1) +6(16)

= 180

Moles of glucose reacted

= 200 ÷180

= $\frac{10}{9}$ mol

Amount of ethanol formed: moles of glucose reacted= 2: 1

Amount of ethanol

= $2(\frac{10}{9} )$

= $\frac{20}{9}$ mol

Mass of ethanol

= $\frac{20}{9} \times[2(12)+6+16]$

= $\frac{20}{9}(46)$

= 102 g (3 s.f.)

Method 2: using mass of carbon dioxide produced

Mole of carbon dioxide produced

= 97.7 ÷[12 +2(16)]

= 97.7 ÷44

= $\frac{977}{440}$ mol

Moles of ethanol: moles of carbon dioxide= 1: 1

Moles of ethanol formed= $\frac{977}{440}$ mol

Mass of ethanol formed

= $\frac{977}{440} \times[2(12)+6+16]$

= 102 g (3 s.f.)

Thus, 102 g of ethanol are formed.

Requiring industries to recycle 25% of plastics in their manufacturing process is an example of: Risk communication Risk assessm

Tomtit [17]

Answer:

Risk management

Explanation:

Risk communication is exchange of the advice, real-time information and the opinions between the experts and the people which are facing threats to their economic, health, or well-being.

Risk assessment is overall process where the hazards and the risk factors which have potential to cause the harm is identified.

Risk perception is subjective judgement which people/ experts make about characteristics and the severity of the risk.

Risk management is evaluation, identification and prioritization of the risks followed by the coordinated and the economical application of the resources to monitor, minimize and control probability of the unfortunate events.

Thus, Option D is correct because in risk management, a Quantitative Solution is given to decrease risk level like to recycle the plastic.

How many grams of NaC2H3O2 are needed to prepare 350. mL of a 2.75 M solution? (molar mass of

shepuryov [24]

Answer:

78.96 g of NaC2H3O2

Explanation:

We are given;

Volume of the solution as 350 mL
Molarity of the solution as 2.75 M
Molar mass of the solute NaC2H3O2 as 82.04 g/mol

We are required to determine the mass of the solute;

First we determine the number of moles;

Moles = Molarity × Volume

Therefore;

Moles of the solute = 2.75 M × 0.350 L

= 0.9625 moles

Second, we determine the mass

Mass = Moles × Molar mass

= 0.9625 moles × 82.04 g/mol

= 78.9635 g

= 78.96 g

Therefore, the mass of NaC2H3O2 needed is 78.96 g
