Answer:
true because the bonds cannot be broken down
The term which is described as a long, narrow depression in the ocean floor would be ocean trench. They <span>are hemispheric-scale long but narrow topographic depressions of the sea floor. They are also the deepest parts of the ocean floor. Hope this answers the question.</span>
The properties that describe how a material interacts with light are color and reflectivity only.
Both observations use a physical property of matter.
The physical properties of substances are the properties of substances that can be observed without changing the arrangement of atoms in the substance.
The ability of an object to scratch another is known as hardness while the ability to reflect visible light is called reflectivity. Both are physical properties.
The color of a substance results from the interaction of the molecules of the substances with light. Objects have specific colors depending on the wavelength of light absorbed and subsequently emitted by the substance.
Reflectivity deals with the ability of an object to reflect visible light.
Both color and reflectivity describe how a material interacts with light.

Answer:
21.6 g
Explanation:
The reaction that takes place is:
First we<u> convert the given masses of both reactants into moles</u>, using their <em>respective molar masses</em>:
- 9.6 g CH₄ ÷ 16 g/mol = 0.6 mol CH₄
- 64.9 g O₂ ÷ 32 g/mol = 2.03 mol O₂
0.6 moles of CH₄ would react completely with (2 * 0.6) 1.2 moles of O₂. As there are more O₂ moles than required, O₂ is the reactant in excess and CH₄ is the limiting reactant.
Now we <u>calculate how many moles of water are produced</u>, using the <em>number of moles of the limiting reactant</em>:
- 0.6 mol CH₄ *
= 1.2 mol H₂O
Finally we<u> convert 1.2 moles of water into grams</u>, using its <em>molar mass</em>:
- 1.2 mol * 18 g/mol = 21.6 g
