Answer:
<h2>mass = 19.98 g</h2>
Explanation:
To find the mass of 1.11 mol of H2O we must first find it's molecular mass after that we use the formula
<h3>m = M × n</h3>
where
m is the mass
M is the molecular mass
n is the number of moles
From the question
n = 1.11 mol
Taking
M( H) = 1 g/mol , M(O) = 16 g/mol
We have
M( H2O) = 2 + 16 = 18 g/mol
So we have
m = 1.11 × 18
We have the final answer as
<h3>mass = 19.98 g</h3>
Hope this helps you
Answer:
6. Scientific inquiry - D
7. Hypothesis - E
8. Control group - G
9. Experimental group - A
10. Independent variable - B
11. Dependent variable - H
12. Scientific theory - C
13. Scientific law - F
Explanation:
6. Scientific inquiry - D
Scientific inquiry is the study of the explanation for the natural world phenomenon and it requires many scientific steps.
7. Hypothesis - E
A hypothesis is a possible explanation for a phenomenon or problem. It is tested in order to see if true or not.
8. Control group - G
The control group in a scientific experiment is a group of subjects did not get the treatment and left alone.
9. Experimental group - A
The experimental group is another hand group of subjects that gets treatment and shows the effect of the variable being tested.
10. Independent variable - B
Independent variables change or manipulated during an experiment and cause a response from the dependent variable.
11. Dependent variable - H
The dependent variable is a variable that is dependent on independent variables and changes in the independent variable.
12. Scientific theory - C
A well-tested explanation for experimental results with the scientific process.
13. Scientific law - F
This describes an observed pattern in nature
