Empirical formula is the simplest way the molecular formula can be wrote so here 7 goes into all of these so it would be CH2O
Well....the answer is HCO3....but i don't know what it is said in worded form.
Looking at the names....it is probably Hydrogen Carbonate

Answer:
-219
Explanation:
1.5(339) - 1.5(485) = -219
Answer:
72
Explanation:
The pattern here may be hard to find at first, but it's this: the number in the middle of the triangle = (number at lower left corner of triangle x number at upper vertex of triangle) + (number at upper vertex of triangle x number at lower right corner of triangle).
Thus, for the missing value...
Missing value = (3x8) + (8x6) = 24+48 = 72.
Could you tell me what concept in chemistry relates to this? I'm interested.
Also check out stylesben's answer. Seems like there's several ways of doing this.
