What lens could get dirty with oil if you move the revolving nosepiece in the wrong direction after viewing under oil immersion?.
From what we know, we can confirm that doing this may dirty and cause harm to your 40x lens.
Why would this cause harm to your lens?Oil immersion is a technique that can be quite handy when attempting to view hard-to-see specimens. However, This should be done only with lenses that are made specifically for this, so revolving the nosepiece in the wrong direction will expose the 40x lens to the oil, for which it is not designed, and may cause harm to the equipment.
Therefore, we can confirm that the 40x lens could get dirty with oil if you move the revolving nosepiece in the wrong direction after viewing it under oil immersion.

what type of energy transfer occurs as a coiled spring is released
Explanation:
Hope it helps you :)
Keep Learning :)
Have a good day :)
When a coiled spring is released, the type of energy transfer that occurs is from potential energy to kinetic energy. When the spring is compressed and coiled, it stores potential energy due to the deformation of its structure.
The potential energy is in the form of elastic potential energy. As soon as the spring is released, it starts to expand, and this potential energy is converted into kinetic energy as the spring gains velocity and starts moving. At the maximum expansion (when the spring reaches its natural length), all the potential energy is converted into kinetic energy. The kinetic energy will continue to drive the motion of the spring until it comes to a stop or transfers its energy to another object or system.

What would happen if the amount of sodium azide used was far greater or far less thanIts 1424 grams of sodium azide which is required to produce 736 L of Nitrogen gas with the density of 1.25 g/LIts
Based on the stoichiometry of the reaction, If the mass of sodium azide used was far greater than 1424 g, the volume of nitrogen gas produced will be far greater than 736 L.
However, If the mass of sodium azide used was far less than 1424 g, the volume of nitrogen gas produced will be far less than 736 L.
What is sodium azide used for?Sodium azide is the chemical found in automobile airbags.
Automotive air bags inflate when an electrical charge triggered by automobile impact causes sodium azide, NaN3, to rapidly decompose to its component elements, nitrogen gas and sodium
The equation of the reaction is given below:
2 NaN3(s) → 2 Na(s) + 3 N2(g)According to the equation of reaction, 2 moles of sodium azide produces 3 moles of nitrogen gas.
1 mole of Nitrogen gas has a volume of 22.4 L
Molar mass of sodium azide is 65 g
Moles of sodium azide in 1424 g = 1424/65 = 21.9077 moles
21.9077 moles of sodium azide will produce 21.9077 * 3/2 moles of nitrogen gas = 32.86 moles of nitrogen gas
32.86 moles of nitrogen gas will occupy a volume of 32.86 * 22.4 = 736 L
If the mass of sodium azide used was far greater than 1424 g, the volume of nitrogen gas produced will be far greater than 736 L.
If the mass of sodium azide used was far less than 1424 g, the volume of nitrogen gas produced will be far less than 736 L.

Do humans depend on photosynthesis? Explain how, why, or why not. (1 point)

Yes, all of the food consumed by humans is plants or gets energy from plants, and plants produce their own food through photosynthesis.
No, humans rely on animals for food, and neither humans nor animals depend on photosynthesis for food.
No, humans rely on animals for food, and neither humans nor animals depend on photosynthesis for food.
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.
Hope this helps.
Yes, all of the food consumed by humans is plants or gets energy from plants, and plants produce their own food through photosynthesis. Therefore, the correct option is option C.
The light-dependent processes and the light-independent reactions, also referred to as the Calvin cycle, are the two primary stages of photosynthesis. The thylakoid membrane of the chloroplasts in plant cells is where the first stage, the light-dependent processes, take place. In this phase, the pigments chlorophyll and other chloroplast-based pigments absorb solar energy and transform it into chemical energy in the form of ATP and NADPH (nicotinamide adenine dinucleotide phosphate). These chemicals are necessary to drive the following phase of photosynthesis.
Therefore, the correct option is option C.

Ammonia, NH3, is made in the direct reaction between nitrogen and hydrogen. If 280. grams of nitrogen are used,
how many grams of hydrogen are also used?
Answer:
The answer is 60 grams of hydrogen.
Explanation:
Assuming hydrogen is a non-limited substance, we can calculate the number of mols of nitrogen that are used.
Molar mass of N = 14 grams/mole
280g of N / (14 g / mol) = 20 mols of N
They react in a 1 to 3 ratio. For every 1 nitrogen atom, there are 3 hydrogen atoms.
The molar mass of hydrogen is 1 g / mol.
Because we have 20 mols of Nitrogen and we know we need three times the amount of hydrogen as we do nitrogen, there must be 60 mols of hydrogen.
60 * 1 = 60
The answer is 60 grams of hydrogen.

By definition, what type of fatty acid has double bonds?.
Answer:
Fatty acids are comprised of hydrocarbon chains terminating with carboxylic acid groups. Fatty acids and their associated derivatives are the primary components of lipids. The length and degree of saturation of the hydrocarbon chain is highly variable between each fatty acid, and dictates the associated physical properties (e.g., melting point and fluidity). Moreover, fatty acids are responsible for the hydrophobic properties (insoluble in water) exhibited by lipids.
Function of Fatty Acids
Explanation:
The type of fatty acids that have double bonds is unsaturated fatty acids.
What are unsaturated fatty acids?
Unsaturated fat is a fatty acid containing two carbons that share a double or triple bond and are not entirely saturated with hydrogen atoms. The structures are weaker and often liquid (oil) at room temperature as a result of the lower hydrogen-bond saturation.
Vegetables and fish are more likely to contain unsaturated fats than other foods. In contrast, saturated fats are solid at room temperature and are often present in animal products.
The human body relies on unsaturated fats as a major source of calories and, consequently, energy. Fats are the most concentrated source of energy in food and are typically composed of carbon, hydrogen, and oxygen.
The three primary nutrients in a diet are carbohydrates, proteins, and fats. According to how many hydrogen bonds they contain, fats are classified as either saturated (all hydrogen bonds) or unsaturated (not all hydrogen bonds).
Therefore, unsaturated fatty acids have double bonds.
