<u>Answer:</u> The bronsted acids for the given reaction are
<u>Explanation:</u>
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses or donates protons and thus forming conjugate base.
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
For the given chemical equation:
For the forward reaction, looses 1 proton to form and thus acts as bronsted acid.
For the backward reaction, looses 1 proton to form and thus acts as bronsted acid
Hence, the bronsted acids for the given reaction are
Answer:
bond to form a covalent bond
Explanation:
a covalent bond is formed when two atoms share electron pairs.
Im pretty sure its the sun.
Hope you have a grrreat day!
The chemical symbol for sodium bicarbonate is NaHCO₃. Its molar mass is calculated by adding the product of the molar mass of each of the component and the number of moles. That is,
molar mass of NaHCO₃ = (1 mol Na)(23 g Na/1 mol Na) + (1 mol H)(1 g H/ 1 mol H) + (1 mol C)(12 g C/1 mol C) + (3 mol O)(16 g O/1 mol O)
molar mass of NaHCO₃ = 84 g/mol
Same is to be done with sodium carbonate which has a molar mass of Na₂CO₃
molar mass of Na₂CO₃ = (2 mol Na)(23 g Na/1 mol Na) + (1 mol C)(12 g C/1 mol C) + (3 mol O)(16 g O/1 mol O)
molar mass of Na₂CO₃ = 106 g/mol
The decomposition of sodium bicarbonate to sodium carbonate is shwon below,
2NaHCO₃ --> Na₂CO₃ + H₂O + CO₂
Through conversion factors and dimensional analysis,
(1.678 g NaHCO₃)(1 mol NaHCO₃/84 g NaHCO₃)(1 mol Na₂CO₃/2 mol NaHCO₃)(106 g NaHCO₃/1 mol NaHCO₃)
= 1.06 g Na₂CO₃
<em>ANSWER: 1.06 g Na₂CO₃</em>
