Answer;
- It will sink because soap disrupts the inter-molecular forces of water
Explanation;
-A light twig is barely floating on the surface of water. if a drop of dish washing detergent is added near it then it will sink because soap disrupts the inter- molecular forces of water.
-The twig was initially floating due to the force of surface tension created by the inter-molecular forces between water molecules. When soap is added to the water, the twig will be driven to sink by the disruption of the water's surface tension. This is because soap is a surfacant that is amphipathic and thus disrupts the inter-molecular forces between water molecules that are responsible for surface tension.
b. combustion
c. replacement
d. decomposition
Answer:
D. decomposition
Explanation:
Synthesis reaction occurs when two elements or compounds react to originate a new one:
A + B ⇒ C
Combustion occurs when a fuel reacts with oxygen to form CO₂ and water:
A + O₂ ⇒ CO₂ + H₂O
Replacement reaction can be simple or double. Simple occurs when a simple element replaces others in a compound:
A + BC ⇒ B + AC
Double occurs when two compounds replace elements between them:
AB + CD ⇒ AC + BD
Decomposition reaction occurs when a compound originates two or more compounds
A ⇒ B + C
So, the reaction given is a decomposition chemical reaction.
2MgO → 2Mg + O2 is an example of a decomposition chemical reaction. The answer is letter D. It is not a replacement reaction because no other compound is involved. It is not a combustion reaction because no oxygen is involved.
b)It contains particles that can settle out.
C)It has nutrients that are dissolved in its liquid portion.
D)It contains particles that mix on a molecular level.

Answer:
Chlorine
Explanation:
Chlorine is a halogen that is a strong oxidizer (it takes electrons from nearby compounds). In so doing, it kills bacteria, viruses, and other microorganisms. The chlorine reacts with cell walls or other vital organic compounds (e.g., proteins) to render them useless. Chlorine is relatively inexpensive and generally easy to handle, but it is dangerous in gaseous form and highly alkaline in solution, so must be stored and handled properly.
produced during respiration?
W
X
Y
Z
Answer:
X
Explanation:
Letter X is mitochondria. The mitochondria produces carbon dioxide, water, and ATP energy during cellular respiration.
