Answer:
820.864 g
Explanation:
1) The atomic mass of sulfur (found from the periodic table) is 32.065 amu. Use this mass to find the molar mass of Sulfur. Sulfur is S8 so the molar mass of sulfur is:
8 × 32.065 = 256.52 g/mol
2) To find the mass use the formula:
m = n × M where <em>m</em><em> </em>is the mass, <em>n</em><em> </em>is the number of moles, and <em>M</em><em> </em>is the molar mass.
3)
<h2>The baking of a Pizza be Categorize as Endothermic Process</h2>
The baking of a pizza should be categorized as an endothermic process because the dough absorbs heat. An endothermic process is a method that absorbs energy from its surroundings which is habitually in the form of energy.
It can be a biochemical process like solving the salt in water or just the melting of ice. Therefore, the dough absorbs heat and it is categorized as an endothermic process.
Answer:
It increases when the temperature increases.
Explanation:
- According to Arrhenius relation: k = Ae(-Ea/RT).
- The rate constant of the reaction and also the rate of the reaction increases exponentially with increasing the temperature of the reaction.
- As the temperature increases, the no. of molecules that can posses the critical energy (activation energy) to initiate the chemical reaction and pass the energy barrier increases.
Answer:
6. protons, mass number from the atomic number
7. Li= ,
Hi there!
A mole is a type of unit measurement for an amount of a substance like in your cast, salt.
One mole of salt will be the equivalent to 58 grams
Hope this helped!~
