Answer:
One that “Can be answered by conducting an experiment”
Explanation:
Answer:
9.29 mol
Explanation:
Given data:
Number of moles = ?
Mass = 148.6 g
Solution:
Number of moles = mass/ molar mass
Molar mass of CH₄ = 16 g/mol
Now we will put the values in formula.
Number of moles = 148.6 g/ 16 g/mol
Number of moles = 9.29 mol
Thus 148.6 g have 9.29 moles.
Answer:
True
Explanation:
Confirmation Bias is the tendency to look for information that supports, rather than rejects, one’s preconceptions, typically by interpreting evidence to confirm existing beliefs while rejecting or ignoring any conflicting data
A scientific theory is a well tested explanation of a natural phenomenon.
Given:
The overall average speed = 25 cm/s.
The overall average speed increased by 10%.
To find:
The new overall average speed.
Solution:
We have,
Overall average speed = 25 cm/s.
The overall average speed increased by 10%. So, the new average speed is
New overall average speed = Initial average speed + 10% of initial overall average speed



Therefore, the new overall average speed is 27.5 cm/s.
