The potential energy of the reactants is 200J.
From the energy diagram, the energy of the product formed is 350J; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.<span />
The number of electrons shared between the atoms in a I₂ molecule is two (2).
Explanation:
An iodine atom has 53 electrons and its electron configuration is;
2. 8. 8. 18. 17
1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁵
Note that the outermost p shell has 5 electrons while it can accommodate a maximum of 6 for stable electron configuration. Therefore an Iodine atom needs one (1) electron to acquire nobility. Two Iodine atoms will, therefore, share two electrons (each from one of their p sub-shell ) by covalent bonds to form I₂

Answer:a) 2C4H10 + 13O2 —> 8CO2 + 10H2O. Oxidation reaction
b) 8 (4 moles CO2 per mole butane)
Explanation:
could be written C4H10 + 6 1/2 O2 —> 4CO2 + 5H2O
Although all gases closely follow the ideal gas law PV = nRT under appropriate conditions, each gas is also a unique chemical substance consisting of molecular units that have definite masses. In this lesson we will see how these molecular masses affect the properties of gases that conform to the ideal gas law.
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
