Answer:
A bonding that occurs between high electronegative atoms such are N, F, O and H atoms, is called a hydrogen bond. Hydrogen bond is a very strong bond. (C)
If hydrogen bonds are not formed between H atoms and N, F, O atom, then the atoms interact through dispersion forces (also known as london dispersion forces). Dispersion forces are weak and they are temporary forces formed by overlapping of orbitals. (B)
Answer:
the answer is not correct
Answer: the cell will absorb more water which can lead to haemolysis (rising and bursting of the cell)
Explanation:
(cm3) is a commonly used unit of volume that extends the derived SI-unit cubic metre, and corresponds to the volume of a cube that measures 1 cm × 1 cm × 1 cm.
so the answer is volume
Answer:
Some of the product is a gas that goes to the atmosphere.
Explanation:
Based on the chemical reaction of baking soda (Sodium bicarbonate: NaHCO₃) with vinegar (Acetic acid: CH₃COOH):
NaHCO₃(aq) + CH₃COOH(aq) → H₂O(aq) + CO₂(g) + CH₃COONa(aq)
When the reaction occurs, one of the products (CO₂) is a gas that will disappear of the mixture to stay in the atmosphere. That is the reason why there are missing 3 grams.
