Answer:
The balanced chemical equation will be "
".
Explanation:
The given equation is:
<u>Step 1:</u>
<u></u>
...(equation 1)
<u>Step 2:</u>
<u></u>...(equation 2)
On adding "equation 1" and "equation 2", we get
⇒ 
⇒
The second step:
⇒
Answer:
Explanation:
1. Please provide the enthalpy info - I will work on it with the info
2.
i) Reaction a should be modified to match the number of S in equation:
2S + 2O2 -> 2SO2 deltaH = -370kJ
ii) Reaction b should be written reversely to match the reactants of SO2:
2SO2 + O2 -> 2SO3 deltaH = 256kJ
iii) Adding the equations together:
2S + 3O2 -> 2SO3
iv) Enthalpy of the combined reaction = -370+256 = -114kJ
It is negative so the reaction is exothermic.
The excerpt from an essay about higher education that most clearly shows an example of logos is:
- Option d: Many college students look to land an exciting internship, believing that it will open doors in their field of study. However, internships can often distract from schoolwork.

Answer:
Molar mass of Ca = 40 g / mol , given 123 g Ca is 123/40= 3.075 moles,
1 mole = 6.022 * 10^23 atoms, so 3.075 moles Ca= 18.51*10^23 atoms
Explanation:
To find the answer you need to use the formula that will help you to find the density. Density = mass/volume
d = 43.2g/96.5mL = 0.45g/mL
