Baking soda is a bicarbonate, which means that each molecule of baking soda
contains a sodium atom, a H atom, an O2 atom, and a CO2 molecule.
Vinegar contains acetic acid, and each molecule contains a H atom, and an acetate ion.
When they're combined, the hydrogen atom in the acetic acid meets up with the H and O2 atoms in the baking soda to form a molecule of water, while the acetate ion grabs onto the sodium atom and forms a salt, sodium, acetate. The CO2 molecule, free of its other chemical bonds, can now escape, and bubbles form as a gas.
Taking into account the reaction stoichiometry, you can observe that:
- one mole of Ca₃P₂ produces 2 mol of PH₃.
- the mole ratio between phosphine and calcium phosphide is 2 mol PH₃ over 1 mol Ca₃P₂.
<h3>Reaction stoichiometry</h3>
In first place, the balanced reaction is:
Ca₃P₂ + 6 H₂O → 3 Ca(OH)₂ + 2 PH₃
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- Ca₃P₂:1 mole
- H₂O: 6 moles
- Ca(OH)₂: 3 moles
- PH₃: 2 moles
The molar mass of the compounds is:
- Ca₃P₂: 182 g/mole
- H₂O: 18 g/mole
- Ca(OH)₂: 74 g/mole
- PH₃: 34 g/mole
Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
- Ca₃P₂: 1 mole ×182 g/mole= 182 grams
- H₂O: 6 moles× 18 g/mole= 108 grams
- Ca(OH)₂: 3 moles ×74 g/mole= 222 grams
- PH₃: 2 moles ×34 g/mole= 68 grams
<h3>Correct statements</h3>
Then, by reaction stoichiometry, you can observe that:
- one mole of Ca₃P₂ produces 2 mol of PH₃.
- the mole ratio between phosphine and calcium phosphide is 2 mol PH₃ over 1 mol Ca₃P₂.

hi there
your answer would be
- n liquid phase in the atoms are somewhat kinda closely packed where as other atoms are very loosely packed in gas phase.
- The Liquids phase cannot be in compressed while the gas phase can be compressed
- Both liquids phase and gases phase do not have a the definite shape and take of the shape of the container in which they are stored in .
i hope this helps you out
have a great morning

Answer:
C₆H₁₅O₃N + H₂O ⇄ C₆H₁₅O₃NH⁺ + OH⁻
Explanation:
A Bronsted-Lowry base is defined as a substance than can accept a proton, H⁺.
When triethanolamine, C₆H₁₅O₃N, reacts with water, H₂O, as follows:
<h3>C₆H₁₅O₃N + H₂O ⇄ C₆H₁₅O₃NH⁺ + OH⁻</h3><h3 />
As you can see, in this reaction, triethanolamine is able to accept a proton that is given for the water.
