how many moles of water are produced from the reaction of 50.0g of methane?
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.

Explanation:
From the diagram, the type of tide Australia is likely to be experiencing is: neap tides.
A tide can be defined as the rise and fall of water level in water bodies such as lakes and oceans, especially due to the gravitational force of attraction exerted by the Moon and Sun on planet Earth.
Generally, there are two (2) main types of a tide and these include:
High tide.Low tide.Additionally, the two (2) form of a tide are:
I. Spring tide: it occur s twice each month close to the the full and new
moons, especially when the Moon and Sun pull together.
II. Neap tide: it occurs two times in a month when the Moon is close to its first and last quarters, especially when the Moon and Sun pull at a right angle.
From the diagram, the type of tide Australia is likely to be experiencing is neap tides because it happened when the Moon is close to its first and last quarters and the Moon and Sun were pulling at a right angle.

Answer:
C. A new gas was created and the gas took up more space
Answer:
C
Explanation:
Which water feature is often associated with condensation?
Frozen lakes
The ocean
Clouds and fog
Water vapor rising from plants
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.

2. How can you as an individual help tackle this problem? (What specifically can you do?)
Answer:
1.Our results indicate that, at higher biodiversity, the impact of acidification on otherwise highly vulnerable key organisms can be reduced by 50 to >90%, depending on the species
2.Positive attitude is sometimes all it takes to turn a bad situation around. On the other side, a bad attitude can take a problem and quickly make it worse. Helps You Make Good Decisions – Anger clouds your judgement. When you let yourself get upset, you impact your ability to make good decisions.

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.

Hello everybody! Can somebody help me please with these two questions? ( I don't know if it's really chemistry if not sorry! )
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.
