A cell membrane will allow the oxygen to enter by diffusion. Diffusion is the movement of particles from an are of higher concentration to an area of lower concentration. Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion.

when heat is removed from a substance, describe how are the molecules affected

Answers

Answer: look at explanation

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.

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.

Which water feature is often associated with condensation?
Frozen lakes
The ocean
Clouds and fog
Water vapor rising from plants

Answers

I think it is water vapor since condensation is the process of water vapor going back to liquid water.

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.

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

Answers

Convert mass of CH4 to moles using the formula

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.
