Answer:
9.79740949850 moles
Explanation:
- 1 mole = Avogardo's Number <<6.022 E 23 <<particles, atoms, etc.>>
- This problem can be solved using dimensional analysis by multiplying atoms (5.9E24 atoms) by (1) mole and then dividing the number by Avogardo's number (6.022 E 23 atoms).
- Note: E = * 10
Side Note: Please let me know if you need any clarifications about this!
Her model allows Christina to gather data about wave P, since she created a model.
Adding energy can put the reaction in a state of equilibrium because more energy allows the reverse reaction, which is endothermic, to occur along with the forward reaction
Hope this helps
Answer:
C.
Explanation:
Since we are trying to find the amount of moles of oxygen, we use the balanced equation to help us out. Since there are 4 moles of Sb for every 3 moles of oxygen, we must use a conversion to let us get rid of the Sb unit and get our desired unit of moles of oxygen. Therefore, C is our best answer.
Answer:
The correct answer is D it is exothermic.
Explanation:
Enthalpy is a state function of a system. Enthalpy is measure of heat content of a system.
Exothethermic reation proceed with liberation of energy in form of heat.As a result enthalpy is positive in case of Exothermic reaction.
