Answer:

The four unusual properties of water that are in direct result of hydrogen bonding are:

1) high boiling point and freezing point. There hydrogen bond in water makes it very slow to boil and freeze.

2) has the highest surface tension among all the liquid.

3) high heat of vaporization. Has a heat of vaporization of 41 kJ/mol.

4) strong intermolecular forces makes water have low vapor pressure, low viscocity, and highly cohesive.

3. The buccal cavity comprises ________,_______and __________.
Ostrovityanka [42]

The movement of food through the esophagus  is called peristalsis.

<h3>What is the buccal cavity?</h3>

The mouth is what we generally call the buccal cavity. It is an opening that contains the teeth and the tongue. The tongue plays the important role of serving as the organ of taste while the teeth serves to marsh food. It is the white strong structure that occurs in the mouth that enables is to masticate our food. Also in the mouth we have the salivary gland which plays the role of secreting the saliva and we know that the saliva contains from enzymes that makes it possible for the digestion of food to commence at the moth. It the follows that the buccal cavity is made up of the teeth, tongue and salivary glands.

Food moves into the stomach via the esophagus. Thus movement is slow and is aided by the muscles that line the gastro intestinal tract. As such, movement of food through the esophagus  is called peristalsis.

Which equation satisfies the law of conservation of matter?
BartSMP [9]

Answer:

The correct answer is A. 3O₂ + 2Al → 2AlO₃

Law of conservation of mass states that mass can nether be created nor destroyed in a closed system or chemical reaction i.e. the total mass of the matter always remains the same throughout the chemical or physical change.

For example, in the given reaction 3O₂ + 2Al → 2AlO₃ the total mass of the reactants is equal to the total mass of the product.

Mass of oxygen = 16 x 3 = 48 AMU

Mass of aluminium = 2 x 27 = 54 AMU

Total molecular mass of the reactants = 102 AMU

Total molecular mass of the product = 2 x 27 + 6 x 8 = 102 AMU.

Hence, the total mass of the matter remains the same.
