The equation for the alpha decay of gold is accurate. You indicate that the alpha particle has the same composition as the helium nucleus of two protons and two neutrons and its ejection from the unstable Gold- 173 results in the formation if Iridium-169. Your beta decay equation of Iodine-138 is also correct. You represent that the ejection of the electron from the nuclear of Iodine -138 will result in the formation of a Xenon 138 nuclear due to the change of the atomic number caused by the electrons negative charge. The electron capture of cadmium, on the other hand, is also accurate. You represent that when the cadmium-104 nucleus captures the electron, it results in silver- 104 because of the reduction of the atomic number caused by the negative charge of the electron. Your responses on the equation are both correct given that the number of molecules in the complete combustion balance on both sided. However, I was wondering if it is better to express the oxygen molecule as a fraction as opposed to making it a whole number. Secondly, what is the toxicity of CO gas to human health?
The equation on the alpha decay of Gold is accurate you indicate that it results in the formation of Iridium-169 with an atomic number of 77. Similarly, your equation on the beta decay of Iodine and cadmium capturing an electron is also right. You correctly identify the formation of Xenon-138 nucleus that has an atomic number of 54 in the beta decay and the formation of Silver- 104 nucleus that has an atomic number of 47. It is also impressive on how you have explained the processes of incomplete and the complete combustion of methane gas with balanced equations. However, would it be better to represent the molecules in the equation of the incomplete combustion of methane to produce water and carbon monoxide as whole numbers because the oxygen molecule doesn't occur in a fraction? Finally, the health concern of carbon monoxide is correct.
Delegate your assignment to our experts and they will do the rest.
The equation on the alpha decay of Gold is accurate you indicate that it results in the formation of Iridium 169 with an atomic number of 77. Similarly, your equation on the beta decay of Iodine and cadmium capturing an electron is also right. In the beta decay of Iodine-138, you correctly identify the formation of Xenon-138 nucleus that has an atomic number of 54 and the formation of Silver- 104 nucleus that has an atomic number of 47 when cadmium-104 nucleus accepts an electron. It is essential also to note that your equations of the complete and incomplete combustion of methane are balanced. You, however, need to include the arrow indicating the process. Secondly, you state that incomplete combustion of methane occurs due to limited time and lack of air. Kindly clarify if the reaction is time depended. Also, it is good to note that air is a mixture of gases that include nitrogen, oxygen, carbon dioxide, and inert gases could you be specific on what constituent of air is not enough in the reaction? Nonetheless, the health concern of carbon monoxide is impressive.
