The nature of reactants, temperature, concentration, surface area and catalysts.
Answer:
The balanced equations for the reactions are outlined below:
Explanation:
A balanced equation describes how many (number of moles) atoms of the reactant give rise to how many (number of moles) of product.
- Hydrogen sulfide gas () and oxygen gas () react to produce sulfur dioxide gas () and water vapor gas.
- The balanced equation for the reaction, taking into consideration the states is:
→
Vanadium(II) oxide (VO) is oxidized by iron(III) oxide (Fe2O3) resulting in the formation of vanadium(V) oxide (V2O5) and iron(II) oxide (FeO).
The balanced equation:
→
Answer:
There are 5 significant figures
In order to find out how many protons a sodium atom has, you have to look at the periodic table. Sodium is Na on the periodic table and you look for the number on the top of the symbol and you can see that it has 11 protons. To find out how many neutrons, you have to subtract 11 from the mass number, which is 23. 23-11 = 12.
12 neutrons; 11 protons
The electromagnetic force is responsible for the electrostatic attraction and repulsion between charged particles and since the protons have positive charge and electrons have negative charge so the electromagnetic force will be the fundamental force primarily responsible for the attraction between electrons and protons
