Please do not request emails. Please ask questions in the forum in the thread. That is the point of the forum.ASMA HASSAN said:please i have more question..
can i get your email?
Jonathan Scott said:Chemistry is not my subject, but I thought a "mole ratio" was simply the numerical ratio of the number of moles of molecules needed to make a balanced reaction, or in certain cases where the substance doesn't come in molecules, it's in terms of the basic unit, atom or ionic formula. (It can then be multiplied by the molecular or unit weight to determine appropriate ratios of masses of reactants). For example, if the reactants are hydrogen and oxygen gases (H2 and O2) forming water (H2O) then the mole ratio of hydrogen to oxygen is 2:1, the same as the atom ratio, but if one is reacting solid carbon (where the unit is C) with oxygen gas (O2) to make carbon dioxide (CO2) then the mole ratio is 1:1 but the atom ratio is 1:2. Can a chemist confirm that this is correct?
Since O is not a molecule, and for that matter neither is C the "mole ratio" part of this question doesn't make much sense to me, and appears to require an additional assumption. I would personally state my assumption and answer the question on that basis.

The best way to get a fast help is to clearly state your problem and provide all necessary information, such as any error messages or steps you have already taken to try and solve the issue. This will help the person assisting you to understand the problem and provide a quicker solution.
To ensure a fast help, it is important to reach out to the appropriate person or resource. If you are seeking help from a specific individual, make sure to contact them directly. If you are seeking help from a company or organization, check their website or contact their customer service for the best way to receive assistance.
While there is no specific format, it is helpful to be clear and concise when asking for help. Include relevant details and try to avoid unnecessary information. Using bullet points or numbered lists can also help organize your request and make it easier for the person assisting you to understand your problem.
The time it takes to receive a fast help varies depending on the complexity of the problem and the availability of the person or resource providing assistance. It is best to be patient and understanding, but if you feel that your request has been overlooked or ignored, it is appropriate to follow up after a reasonable amount of time has passed.
If you are unable to receive a fast help from the initial source you reached out to, there are other resources you can utilize. Online forums and communities, social media groups, and other support networks can often provide quick and helpful solutions. It is also a good idea to keep a list of helpful resources or contacts for future reference.
