Is coding harder than math?
I don’t have this problem with mathematics, yes it can be very difficult at times but with enough time and effort spent I can eventually have a proper understandning of what I need to know This is not the case with programming, no matter how much time I simply can’t learn it
What is the most difficult field of physics?
quantum field theory
What’s the hardest topic in chemistry?
What is the hardest unit in Grade 12 chemistry?
Organic chem is probably the hardest
What is the most important concept in chemistry?
Most crucial in chemistry is the concept of a mole (gram-atomic/molecular weight) In calculus the key (and for many, the difficult) concept is the concept of a limit and what it means to “approach the limit” In chemistry the key (and for many, the difficult) concept is the concept of a mole
How can I learn chemistry easily?
Listen and copy down all key verbal points and concepts discussed during the lecture After each lecture take a few minutes to review your notes Make sure you understand all the concepts covered in the lecture Use your textbook to improve your notes and understanding of key concepts covered
Is atom A chemistry?
Atoms and molecules follow the rules of chemistry and physics, even when they’re part of a complex, living, breathing being If you learned in chemistry that some atoms tend to gain or lose electrons or form bonds with each other, those facts remain true even when the atoms or molecules are part of a living thing
What does stoichiometry mean?
Stoichiometry is a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data In Greek, stoikhein means element and metron means measure, so stoichiometry literally translated means the measure of elements
What are the 4 types of stoichiometry problems?
4 types of stoichiometry problems
- Mole – mole
- Mole – mass
- Mass – mole
- Mass – mass
Why is stoichiometry so hard?
Stoichiometry can be difficult because it builds upon a number of individual skills To be successful you must master the skills and learn how to plan your problem solving strategy Master each of these skills before moving on: Calculating Molar Mass
How do you convert stoichiometry?
There are four steps in solving a stoichiometry problem:
- Write the balanced chemical equation
- Convert the units of the given substance (A) to moles
- Use the mole ratio to calculate the moles of wanted substance (B)
- Convert moles of the wanted substance to the desired units
What is mole ratio?
A mole ratio is a conversion factor that relates the amounts in moles of any two substances in a chemical reaction The numbers in a conversion factor come from the coefficients of the balanced chemical equation
How do I calculate moles?
Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams
Is stoichiometry easy?
Students, however, often find stoichiometry problems difficult because they involve calculations of the number of moles of substances The key to making stoichiometry problems easy is to adopt and practice a methodical approach to the problems Balance the chemical reaction equation
How do we use stoichiometry in real life?
The principles of stoichiometry can be used while cooking If you were almost out of a specific ingredient, you could use the principles of stoichiometry to figure out how much of every other ingredient you would need (treating the ingredient you were almost out of as the “limiting reagent”)
How many molecules are in a mole?
The mole is represented by Avogadro’s number, which is sup>23 atoms or molecules per mol
