Answer : The molecular formula of the compound will be, 
Explanation :
Empirical formula : It is the simplest form of the chemical formula which depicts the whole number of atoms of each element present in the compound.
Molecular formula : it is the chemical formula which depicts the actual number of atoms of each element present in the compound.
For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.
The equation used to calculate the valency is :
As we are given that the empirical formula of a compound is 
and the molar mass of compound is, 90.09 gram/mol.
The empirical mass of = 1(12) + 2(1) + 1(16) = 30 g/eq
Molecular formula = 
Thus, the molecular formula of the compound will be,
Answer:
A.
Explanation:
I chose this because it seems more reasonable . Because its in the air so im guess that its gravitational bc to stay on top of a hill you need balance . Im sorry if its wrong k . I tried .
The percentage error that would be introduced in a 35.0 mL sample of liquid is 2.86%
<h3>Data obatined from the question</h3>
From the question given, the following data were obtained:
- Absolute error = 1 mL
- True measurement = 35 mL
- Perecentage error =?
<h3>How to determine the percentage error</h3>
The percentage error that would be introduced can be obtained as illustrated below:
Percentage error = (Absolute error / True measurement) × 100
Percentage error = (1 / 35) × 100
Percentage error = 2.86%
Thus, percentage error that would be introduced is 2.86%

Answer:
The temperature of the cold water is lower than the warm one. So, when we put the hand in the warm from the cold water, our hand will absorb heat, causing the hand to feel hot. Thus, we can conclude that the more heat it absorbs, the more hotter it is. Whereas the more heat it releases, the colder it is.
