how many moles of water are produced from the reaction of 50.0g of methane?
Answers
moles = mass /molar mass
mass of CH4 = 50grams
molar mass of CH4 = 16 g/mol
moles = 50/16= 3.125 mol
The molar ratio of CH4 to H2O is 1:2.
This means that 1 mole of CH4 produces 2moles of H2O.
So 3.135 mol will produce 3.125*2 = 6.25moles of H2O.
Convert the 6.25 moles of H2O to mass by multiplying the moles by the molar mass of H2O
6.25*18=112.5 grams of H2O was produced
6.25 moles of H₂O are produced from the reaction of 50.0g of methane.
Number of moles:It is defined as given mass over molar mass.
Number of moles = Given mass / Molar mass
Given:
Mass of CH₄ = 50grams
Molar mass of CH₄ = 16 g/mol
Number of moles = 50 / 16
Number of moles = 3.125 moles
The molar ratio of CH₄ to H₂O is 1:2.
This means that 1 mole of CH₄ produces 2 moles of H₂O.
So, 3.135 moles will produce 3.125*2 = 6.25 moles of H₂O.

when heat is removed from a substance, describe how are the molecules affected
Answers
Explanation: When heat is removed from a substance, the kinetic energy of the molecules decreases (the molecules start to move more slowly).
The changes are caused by the tendency of the system to reach equilibrium and when the surroundings of the substance have lower kinetic energy, heat is transferred to reach thermodynamic equilibrium.
What's happening in whole is that there is a temperature gradient (difference) between the substance and its surroundings, and for eliminating this gradient, heat flows from the hotter substance to the colder surroundings, for them to have the same temperature.
The temperature of the substance decreases because its molecules have lower kinetic energy.

Answers
Answer:
1. C
2. B
Explanation:
1. Most living things need oxygen, water, and food to grow. ... Other living things eat plants or other animals for food. The cells of living things divide, allowing the living things to grow bigger and to change as they grow. The cells divide to form new cells that are different from the original cells.
2. The usual method of prokaryote cell division is termed binary fission. The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane. When the cell begins to pull apart, the replicate and original chromosomes are separated.

Which water feature is often associated with condensation?
Frozen lakes
The ocean
Clouds and fog
Water vapor rising from plants
Answers
Clouds and fog are water features often associated with condensation. The correct option is C.
The process by which water vapour, a gaseous form of water, changes into liquid water is called condensation.
When warm, moist air meets a cooler surface or when the air itself cools, it happens. As a result of this cooling, water vapour loses energy and condenses into tiny water droplets or ice crystals, which are what are seen as clouds or fog.
Even though the ocean and frozen lakes are both connected to water, condensation is not a direct result of either of these. As opposed to condensation, water vapour rising from plants is a result of transpiration.
Thus, the correct option is C.

What is another name for fiber?
Answers
Answer: Thread, strand, tendril and filament are all synonyms of fiber.
Explanation: Fiber is a thread from a vegetable tissue, mineral substance, or textile is formed. It's also a dietary material that contains cellulose, lignin, and pectin.
Let me know if you have any questions.
~ Lily, from Brainly.
There are many other names for fiber. Some of them are Carbohydrate, Non-starch polysaccharide, Dietary fiber, Crude fiber, Insoluble fiber, Soluble fiber, Resistant starch, Prebiotic fiber, and Functional fiber.
Fiber is a type of carbohydrate that the body cannot digest. It is found in plant foods, such as fruits, vegetables, grains, and legumes. Fiber is important for gut health, heart health, and weight management.
The different names for fiber reflect its different properties and functions.
For example, carbohydrate is the general term for all sugars, starches, and fiber.Non-starch polysaccharide is a more specific term for fiber that is not made up of starch.Dietary fiber is the term used to refer to all the fiber that is found in food. Crude fiber is a measure of the total amount of fiber in food, including both soluble and insoluble fiber.Insoluble fiber is the type of fiber that does not dissolve in water. Soluble fiber is the type of fiber that dissolves in water.Resistant starch is a type of starch that is resistant to digestion.Prebiotic fiber is a type of fiber that feeds the beneficial bacteria in the gut.Functional fiber is a type of fiber that has been shown to have health benefits beyond its basic function as a food source.Therefore carbohydrate, non-starch polysaccharide, dietary fiber, crude fiber, insoluble fiber, soluble fiber, resistant starch, prebiotic fiber, and functional fiber are just a few of the names given to fibers.
