What is the mass of 1.5 moles of CO2? Stoichiometry:Stoichiometry is the measurement of elements and is derived from Greek language meaning 'measure of elements'. Stoichiometry is widely used in the field of chemical research, chemical industries and in the manufacture of drugs. This field uses ...
The enthalpy change for the reaction CH4(g) + 2O2(g) arrow CO2(g) + 2H2O(l) is -891 kJ/mol. What quantity of heat is released for each mole of water formed? Using the standard heats of formation, what is the enthalpy change per mole of CO2 for the fol...
A diatomic gas is a gas that can only exist when two of its atoms are bonded together. It cannot exist as a single atom. Examples of diatomic gases are chlorine gas, nitrogen gas and oxygen gas. Answer and Explanation:1 Chlorine gas is a diatomic gas. This means that it ...
根据第四段While sleeping,some of them got tiny electrical stimulation through the wires in their brains.In patients who got the stimulation,rhythms in the two brain areas became more synchronized.(在睡觉时,他们中的一些人通过大脑中的电线受到微小的电刺激。在接受刺激的患者中,两个大脑区域的节奏变得...
The ability for CO2 to warm the surface of a planet through the absorption of infrared radiation is well known. What is much less appreciated, however, is just how effective of a gas it is in maintaining the greenhouse framework that helps to characteri
