In metallic bonding (bonding between two metals), electrons are shared between the atoms in the substance.
The most abundant element in the earths crust is oxygen
In this problem, we can formulate two equations.
First, the overall mass balance of the ointment. The mass of
30% salicylic acid ointment plus the mass of petrolatum must be 50 grams.
x + p = 50
Where x is the mass of 30% salicylic acid ointment and p is
the mass of petrolatum
Second, the component mass balance of salicylic acid:
0.3 * x = 50 * 0.05
x = 8.33 g
Therefore the mass of petrolatum to be used is:
x + p = 50
p = 50 – x
p = 50 – 8.33
p = 41.67 g
Answer:
41.7
Answer:
sorry I'm a dumb small brain
Explanation:
my genes
If I had to answer, I would go with C.) Two elements in the same group
I would choose C because elements in the same group have the same number of valence electrons. When elements have the same number of valence electrons, they are all willing to give/receive them in the same way. Therefore, if placed in water, they will combine with water the same way.
Hope this helps!
