There was land on that surface before there was water
Answer:
As shown in the attachment.
Explanation:
In this case, there are two isomers possible. Isomers are compounds that have the same molecular formular but different structural formular.
Considering the hydrocarbon C8H10, which has 8C expected saturated hydrocarbon. however when there is an excess of 8H, we have C8H18 which is the formular of octane, a member of the alkane family and from monosubstitution reaction which involves reaction with halogens (particularly Chlorine), the reaction will be a repeated substitution reaction where chlorine will be replaced with each of the hydrogen.
Answer:
a) 4480L
b) 56L
Explanation:
To answer this question you need to know that Cl2 molecular weight is 71 g/mol and gas volume at NTP is 22.4 L/mol.
a) 14.2 kg of Cl2 in moles will be: 14.2 kg * (1000g/kg) / ( 71g/mol)= 200 mol
The volume of 200 mol of gas in NTP will be: 200 mol * 22.4L/mol= 4480L
b) every mol is made of 6.02 * 10²³ molecules. Then the volume of the gas will be: (15,055×10²³ molecule) / (6.02 * 10²³ molecules/mol) * 22.4 L/mol= 56L
Sodium chloride is made up of sodium and chlorine.
sodium chlorine would form an ionic bond, which is the transfer of electrons
because sodium is in group 1, it has 1 electron on its outermost shell
because chlorine is in group 7, it has 7 electrons on the outermost shell.
sodium and chlorine both want a full outer shell. therefore, sodium and chlorine will form an ionic bond, and sodium will transfer its one electron to chlorine so that it can lose its electron and get a full outer shell, and chlorine can gain an electron and also get a full outer shell. this can be represented using the dot and cross model. as shown in the picture.
but don't forget to add a 1- charge to chlorine with brackets and a 1+ charge to sodium, also with brackets.
hope this helped.. I know it became really long but I didn't really realise it once I was half way.. anyway, if you have any questions just ask :)
