At the specific temperature no more solute can dissolve

copper chloride

The temperature is decreased so the particles have less kinetic energy and move around much slower which reduces the collision frequency and thus the rate of reaction. Furthermore since the particles have less energy a smaller proportion of collisions have the required activation energy for a reaction to occur so the rate of reaction is decreased.

The copper(II)oxide stops dissolving

Copper nitrate

Metal spoon

The bonding is the electrostatic force between the lattice of positve ions and the 'sea' of delocalised and mobile electrons

Ethanol Butanoic acid

Ethyl Butanoate

Successive units differ by a CH2 unit. Similar chemical properties

CnH2n+1OH Proper substrcipt as in anything not a chemical is subsscripted

mirroring structure increases, decreases decreases, increases

A substance that increases the rate of a chemical reaction without getting changed or used up it

N2H4 + H2O -><- N2H5 + + OH-

Bases are Proton receptors

Pressure: 200 atm Temperature: 450 degrees Catalyst: Iron N2+3H2 -><- 2NH3 (g for all)

Because they are no mobile electrons or ions or charged particles to carry the charge.

N2 is molecular, the forces between the molecules are week. Therefore it takes less energy to break them apart

Covalent

Chlorine Sodium

They have 18 electron and only 16 protons, 2 more electrons than proton.

They have the same number of valence electrons or outer electrons

Because each proton has a charge of 1+ and each electron has a charge of 1- . Since they are the same number of electrons and protons the charges cancel out. (161 + 16-1 =0)

They are the same because they have the same number of protons and the same number of electrons. They are in essence the same element. They differ in terms of their mass number as they have different numbers of neutron (16 and 17)

== equal to operator is a comparision operator which checks if two values are equal

= assignment operators assigns the right value to the left variable

I guess this shows some simplistic models the interpreter uses to evaluate combinations. Basically it subsitutes the definitions of procedures then evalues it like a combination

Sometimes we use normal order evaluation to better understand teh code or something in whcih we keep subsying until we reach a point where we only have primitive procedures. This can be inefficinet so its not used by interpreter but it is used sometimes

Expressions Type into terminal and interpreter prints value Can combine multiple data values with primtiive procedure by using brackets then operator operand structure Argument is the data in operand can complicate expressions by nesting can use pretty printing which uses indents to vertically align expressions in same level of nest making easy to read not neccary to tell interpreter to print

If you improve your small individual habits/ routines and improve them just by a little bit when you put them all together you will see amazing gains
