When cells need to gain or get rid of certain things, diffusion is a form of passive transport that does not require a cell to expand any energy.

Diffusion, put simply, is a way for things to move in and out of the cell. The cell uses diffusion to take in oxygen and glucose and push out carbon dioxide.

What is the charge of a cation?
kolezko [41]

Answer:

A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.

1(a). What is the solubility of calcium chloride (CaCl2) at 5°C?
In-s [12.5K]

Answer:

60 g/100 g water  

Explanation:

Find 5 °C on the horizontal axis.

Draw a line vertically from that point until you reach the solubility curve for CaCl₂.  

Then draw a horizontal line from there to the vertical axis.

The solubility of CaCl₂ is 60 g/100 g water.

vova2212 [387]
Hello!

The fission of an atom that has a large atomic number can be induced by bombarding the atom with neutrons.

Nuclear fission occurs when a heavy nucleus divides into two or more lighter nuclei. This reaction is induced by the bombarding of neutrons into the nucleus, making it unstable (like throwing an orange to a perfectly arranged orange pyramid at the supermarket). The unstable nucleus breaks down into lighter elements, releasing more neutrons which contribute to the chain reaction.

Explain why 1 mole of diethyl ether requires less heat to
gizmo_the_mogwai [7]

The quantity of heat required to vapourize 1 mole of a substance depends on the kind of intermolecular forces between the molecules of the substance. Diethyl ether molecules are held together by weak dispersion forces compared to the stronger hydrogen bonding in ethanol. Therefore,  1 mole of diethyl ether requires less heat to  vapourize than is required to vapourize 1 mole of  ethanol.

Intermolecular forces hold the molecules a substance together in a given state of matter. The properties of a substance such as boiling point, melting point etc are dependent on the nature of intermolecular forces holding the molecules of the substance.

Diethyl ether molecules are held together by weak dispersion forces while molecules of ethanol are held together by hydrogen bonds.

Since hydrogen bonds are much stronger than dispersion forces, a greater quantity of heat is required to break the intermolecular hydrogen bonds in ethanol in order to vapourize them than is required to vapourize diethyl ether.

Therefore, owing to stronger intermolecular forces between molecules of ethanol, less heat is required to vapourize than is required to vapourize 1 mole of  ethanol.
