Answer: 
Explanation:
The balanced chemical reaction is,

The expression for Gibbs free energy change is,
![\Delta G_{rxn}=\sum [n\times \Delta G_(product)]-\sum [n\times \Delta G_(reactant)]](https://tex.z-dn.net/?f=%5CDelta%20G_%7Brxn%7D%3D%5Csum%20%5Bn%5Ctimes%20%5CDelta%20G_%28product%29%5D-%5Csum%20%5Bn%5Ctimes%20%5CDelta%20G_%28reactant%29%5D)
![\Delta G_{rxn}=[(n_{CO_2}\times \Delta G_{CO_2})+(n_{CaO}\times \Delta G_{CaO})]-[(n_{CaCO_3}\times \Delta G_{CaCO_3})]](https://tex.z-dn.net/?f=%5CDelta%20G_%7Brxn%7D%3D%5B%28n_%7BCO_2%7D%5Ctimes%20%5CDelta%20G_%7BCO_2%7D%29%2B%28n_%7BCaO%7D%5Ctimes%20%5CDelta%20G_%7BCaO%7D%29%5D-%5B%28n_%7BCaCO_3%7D%5Ctimes%20%5CDelta%20G_%7BCaCO_3%7D%29%5D)
where,
n = number of moles
Now put all the given values in this expression, we get
![\Delta G_{rxn}=[(1\times -394.4)+(1\times -604.17)]-[(1\times -1128.76)]](https://tex.z-dn.net/?f=%5CDelta%20G_%7Brxn%7D%3D%5B%281%5Ctimes%20-394.4%29%2B%281%5Ctimes%20-604.17%29%5D-%5B%281%5Ctimes%20-1128.76%29%5D)

Therefore, the gibbs free energy for this reaction is, +130.19 kJ
Answer:
Our planet's rotation produces a force on all bodies moving relative to theEarth. ... The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected.
Explanation:
8A+2B——> 6C
since you multiply by a factor of 2 you do that to each letter
4*2=8
1*2=2
3*2=6
Answer : The mass of benzyl salicylate needed to manufacture 350 tubes of sunscreen are, 1.55 kg
Explanation :
As we are given that a sunscreen preparation contains 2.60 % by mass benzyl salicylate. That means, 2.60 grams of benzyl salicylate present in 100 g of solution.
First we have to convert the given mass from oz into kg.
Conversion used:
1 kg = 35.274 oz
or,

So,

Now we have to determine the mass of benzyl salicylate.
As, 100 g of solution contains mass of benzyl salicylate = 2.60 g
So, 0.1701 kg of solution contains mass of benzyl salicylate = 
Now we have to determine the mass of benzyl salicylate are needed to manufacture 350 tubes of sunscreen.
Mass of benzyl salicylate in 350 tubes of sunscreen = 0.00442 kg × 350
Mass of benzyl salicylate in 350 tubes of sunscreen = 1.55 kg
Thus, the mass of benzyl salicylate needed to manufacture 350 tubes of sunscreen are, 1.55 kg
