Answer:
C. Y & Z
Explanation:
V, W are imaginary metals here because their valence electrons are typically less than 4. X, Y, Z are non-metals and have higher valence electrons. Here, if V or W bind with X, Y, or Z we make ionic bond (because metal + non metal = ionic). But, if X binds with Y or Z or any combinations of any two of the three non-metals results in covalent bond (non metal + non metal = covalent).
Thus, Y and Z make covalent.
I believe it’s the third option
Chemically combined to make a new pure substance
The circulatory system moves blood in our bodies. The blood can move oxygen and nutrients to our muscles and limbs. The heartbeat pushes the blood, and the blood cells carry glucose.
Answer:
I believe it is A
Explanation:
pH = -log[H+] and pOH = -log[OH−].
since the unit for the heat of fusion is kJ/mol, you're going to have to convert the grams into moles in order to cancel out the unit. After that, you can solve like normal.
