Answer:
This is google's answer for the last question
Explanation:
The kinetic energy increases as the particles move faster. The potential energy increases as the particles move farther apart. How are thermal energy and temperature related? When the temperature of an object increases, the average kinetic energy of its particles increases.
Answer:
Electrons, they circle the nucleus.
Answer:
539.3mmHg of H₂
179.7mmHg of N₂
Explanation:
Ammonia, NH₃, reacts completely producing N₂ and H₂ thus:
2 NH₃ → N₂ + 3H₂
<em>That means there are produced 4 moles of gases and 3 are of H₂ and 1 of N₂</em>
Total pressure (Sum of pressures of N₂ and H₂) is 719mmHg. 3 parts are of H₂ and 1 of H₂
Thus, partial pressures of the products after reaction are:
719mmHg ₓ (3 H₂ / 4) = 539.3mmHg of H₂
719mmHg ₓ (1 N₂ / 4) = 179.7mmHg of N₂
Answer:
The limiting reactant is the ZnS
Explanation:
The equation for this reaction is:
2 ZnS + 3O₂ = 2 ZnO + 2 SO₂
2 moles of zinc sulfure reacts with 3 moles of oxygen.
Then, 1.72 mol of ZnS would react with ( 1.72 .3)/2 = 2.58 moles of O₂
If we have 3.04 moles, then the oxygen is the reactant in excess.
Let's confirm, the ZnS as the limiting reactant.
3 moles of oxygen react with 2 moles of sulfure.
Then, 3.04 moles of O₂ would react with (3.04 .2) / 3 = 2.02 moles of ZnS
We have 1.72 moles of Zn S and it is not enough for the 2.02 moles that we need, for the reaction.
Global Warming. The temperature is rising ever so slightly , but the effect is astronomical.
