Is the nature of a physical object abstract, logical or beyond logic?
All science fields interrelate to each other in many ways so you find it easy to express multiple things easily. In essence, a concept from a different subject will find ample utilization and acceptance in another one. And thus, it becomes easy for you to keep hold of or track of your concepts witho...

Hello, I need help with the following question.
Study the following Fischer projections to answer the questions below. Is galactose a D-sugar or an L-sugar? Is mannose a D-sugar or an L-sugar? Structural isomerism and stereoisomerism are the two major kinds of isomerism. Stereoisomers with the same chemical structure but non-superimposable mirro...

Re: What does it equal to NaHCO3 + H2O + C2H4O2 = ?
The best fun thing about chemistry is the ability to predict and write almost everything. In essence, by this, I mean that you can conduct different experiments and then even predict and finalize the conclusion in terms of the resulting products. Moreover, even if you are a newcomer to the field of ...

Music and Chemistry
Learning music has become essential nowadays. There are various instruments that we can learn each day like: https://mytutorsource.hk/blog/6-easy-instruments-to-learn/. But what makes me awe at it the most is its connection with other subjects. I recently read somewhere that there is a huge connecti...

Re: What is the reaction formula for Al + LiF?
I would like to take this opportunity in making sure you get the basic knowledge of using chemical equations. At first, it becomes extremely easy if there are no molecules given. For example, if there are no numeric digits before a compound, then it becomes easy to determine the products. All you ha...

Re: BENJAMÍN
Although I possess a little information about chemistry and a mild interest in it, you can still say I do not possess any interest in chemistry at all, but still, I tend to predict a few answers to it. For example, providing what the products will be for a reaction. And if the products do satisfy th...

Re: Physical Science
If I am not wrong, your reaction is either not correct or you are missing some element on the products side. Although your reactant side looks fine enough however given their molecules and the elements, I do not think the products you are showing justify the statement. In order to find the coefficie...

Different Experiments for children
Make big dish soap bubbles I always wondered how people make those big bubbles. I did a little experiment myself. They were quite successful so I thought I would share with everyone. Feel free to drop in your ideas on how to make them even better. I am using 6 cups distilled or purified water, 1 Tab...

Re: Why doesn't Si + Wo3 ignite?
I read in a paper that Si-doping increases and stabilizes the acetone-selective ε-WO3 phase while increasing its thermal stability and, thus, results in superior sensing performance with an optimum at about 10 mol % Si content.

Re: question
The atomic number may be found at the upper left corner, while the atomic weight can be found at the bottom. Atomic number = number of protons. Atoms have no overall electrical charge by definition. This means that the positively charged protons and negatively charged electrons must be in equilibriu...

I read somewhere online that the compounds that appear blue have more conjugation than red compounds. Why is that?
A conjugated system is one in which the single and multiple bonds alternate. The 1, 3 - dienes ring, which has alternate single and double bonds, is an example of a conjugated system. I do know that the ground and excited states of electrons in molecules with conjugated electron systems are closer i...

Balanced equation for the reaction
What single reagent could add that would allow differentiating between the member of each pair of the solid compounds. Also, what would happen to each substance when the reagents are added. I also need a balanced equation for the reaction. AgCl and PbCl2 I know the process is known as qualitative an...
