Answer: C REDUCTION
Explanation:
Guessed after knowing oxidation isn't the answer. Got right
Answer:
58
Explanation:
Due to conservation of energy, the sum of the reactants = the sum of the products. So 28 + 30 = 58g
Answer: P₂=0.44 atm
Explanation:
For this problem, we are dealing with temperature and pressure. We will need to use Gay-Lussac's Law.
Gay-Lussac's Law:
First, let's do some conversions. Anytime we deal with the Ideal Gas Law and the different laws, we need to make sure our temperature is in Kelvins. Since T₂ is 64°C, we must change it to K.
64+273K=337K
Now, it may be uncomfortable to use kPa instead of atm, so let's convert kPa to atm.
Since our units are in atm and K, we can use Gay-Lussac's Law to find P₂.
P₂=0.44 atm
Thus 174 protons would make at most 6 copper atoms. However, it would take 174 extra electrons (29 per atom) and even more neutrons than that to construct neutral copper atoms with stable nuclei.
Answer:
1 : 1
Explanation:
We know that the equation is balanced because the number of zinc, hydrogen, sulfur and oxygen atoms are the same in both sides of the equation.
Zn + H2SO4 → ZnSO4 + H2
We can see that there is one molecule for Zn and also one molecule for ZnSO4 (we know this because there are no numbers before the formulas, so the 1 is implied)
That is why the mole ratio of zinc to zinc sulfate is 1 : 1
