Which of the following best describes a person doing science?
a. dominick uses a computer to do his math homework.
b.
lindsay measures the sizes of the craters on the moon
c. isabel invents a new kind of doorknob.
d. murray randomly predicts the result of a coin toss.

The correct answer is B. Lindsay measures the sizes of the craters on the Moon

Explanation:

Science is the field of knowledge that aims at studying and understanding different types of phenomena that occur in the natural world. Due to this, the Scientific Method includes stages such as observation, creating a hypothesis, testing and sharing results as the main focus is to be able to explain why, how and when a certain event or phenomenon takes place based on logic and evidence. According to this, the statement that describes a person doing science is " Lindsay measures the sizes of the craters on the Moon" because she relies on observation and testing to try to understand a natural phenomenon or element.

yes

explanation:

search chemistry final b exam in google and a site called quizlet will pop up

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
