What is the question? Because that’s true
<h3>
Answer:</h3>
CuO(s) + H₂(g) → Cu(s) + H₂O(l)
<h3>
Explanation:</h3>
- Assuming the reaction is the reduction of CuO by H₂
- Then the balanced equation for the reaction is;
CuO(s) + H₂(g) → Cu(s) + H₂O(l)
- The equation shows the reducing property of hydrogen gas, such that hydrogen reduces metal oxides such as copper(ii)oxide to the respective metals.
- The law of conservation requires chemical equations to be balanced so as the mass of reactants will be equal to that of products.
- In this case; there is 1 copper atom, 1 oxygen atom and 2 hydrogen atoms on both side of the equation and thus the equation is balanced.
Answer: im pretty sure its the last (one daughter cell has no similarity to its parent cell.)
Explanation: bc a daughter cell has 30 and the parent cell would have 46 and thats not twice or half as many and they arent the same either so the last one makes sences
Answer:
N2 has a triple bond with its Lewis structure. Nitrogen has 5 valence electrons. Two nitrogen's have a total of 10 valence electrons. There will be 6 valence electrons that are unequally shared. We move them in the middle. Therefore, Each nitrogen gives three pairs of electrons to the to the other nitrogen atom. N2 has a total of 8 electrons which completes the octet rule.
