Answer:
Nitrogen, Hydrogen, Oxygen, Chlorine, and Fluorine are all gases at room temperature.
Explanation:
Ionic crystals are hard because of tight packing lattices, say, the positive and negative ions are strongly attached among themselves.
The volume in mL of ethanol (C₂H₆O) present in the bottle is 487.5L
HOW TO CALCULATE VOLUME OF ETHANOL:
- According to this question, a particular beer is 65.0% ethanol by volume. This means that the beer contains 65/100 of ethanol.
- If a single bottle of beer contains a total of 750.0 mL of beer, the volume of ethanol in the bottle is calculated as follows:
- Therefore, volume in mL of ethanol (C₂H₆O) present in the bottle is 487.5L

Answer:
Third option
Explanation:
The answer is the third option or "Yes, all of the food consumed by humans is plants or gets energy from plants, and plants produce their own food through photosynthesis." Photosynthesis is the process plants use to obtain their own food. Humans do depend on photosynthesis because not only humans eat plants, but animals. Some animals are herbivores which means they only eat plants. If plants cannot create their own food using photosynthesis, then the plant dies. Neither the human nor the animal can eat that plant.
Many animals rely on plants to eat and if all plants cannot perform photosynthesis, then the animals cannot eat. Us humans eat animals which means if the plants die, the animals who eat the plants die, and then humans die. Humans heavily rely on photosynthesis, so the answer is the third option.
