Answer:
B and A.
Explanation:
Many of the great scientists were religious. But the answer is not D.
A scientist may have strong opinions. That was certainly true of Newton. Most of the time he was right. Still the answer is not C. Science requires an open mind.
The answer is between A and B. Many discoveries were made looking at the natural world. That may provide the inspiration. But I don't think it is the answer. I'm going to say A
B is the other answer. Between A and B many scientific truths have been discovered.

d. a row of elements
Answers
Answer:
d. a row of elements
Explanation:
Elements that are in the same group, have same number of electrons and make up a column in a periodic table.
[tex].[/tex]
The phrase which best describes a period on the periodic table is; a row of elements.
The elements in the periodic table are divided into rows and columns. The rows are called the periods while the columns are called the groups.
This means that a period is best described as a row of elements from the foregoing.
Therefore, the correct answer is option D: a row of elements.

Can pure water exist as a liquid at 110° C ? Why or why not?
Answers
According to forces of attraction and as boiling point is 100°C pure water cannot exist as a liquid at 110° C.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

Which elements would react most easily with each other? (1 point)
an element with a high electronegativity and an element with a full shell of electrons
an element with a high electronegativity and an element with a single valence electron
an element with a high electronegativity and a second element with a high electronegativity
an element with a high electronegativity and an element with low reactivity
Answers
Answer: an element with a high electronegativity and an element with a single valence electron
is the correct answer
_______________________________________________________
Answer:
"Any element with a high electronegativity and an element with a single valence electron would react very easily on contact with each other."_______________________________________________________
"Why?"
For instance, fluorine is the most reactive non-metal element on the periodic table. Due to it's small size, as well as it's strong electronegativity, fluorine has a strong tendency to accept electrons from other atoms and ions. But when Fluorine comes in contact with Hydrogen (a single valence electron element), for instance, it immediately reacts, resulting in an explosion.

what is potential energy
Answers
Answer:
The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
so simple question.
Answer:
Potential energy is stored energy that an object has because of its position.
Explanation:
Consider an example where a ball is thrown from a tall building. The point at which the ball is at its maximum height is said to have the maximum potential energy. As the ball gradually falls down, the potential energy decreases and turns into another form of energy, kinetic energy (energy in the form of motion). The ball at its peak position had stored energy, however, as soon as it begins moving, the stored energy will become less.
You can think of it this way where the ball has less and less distance to cover when falling downwards from the building. This shorter distance covered by the ball is proportional to the potential energy, so when the ball is about to hit the ground, the potential energy will be close to 0.
I hope this makes more sense!
What best describes what the pH number indicates about a solution?
O A. How acidic the solution is
B. What its ionic strength is
O C. How strong the acid is
O D. What the Ka constant is
Answers
Answer:
A. How Acidic the solution is
Explanation: pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
Answer:
A
Explanation:
The pH of a solution indicates it's acidity or alkalinity. The pH scale is an inverse logarithm that ranges from 0 to 14. Anything below 7.0 (ranging from 0.0 to 6.9) is acidic and anything above 7.0 ( from 7.1 to 14. 0) is basic or alkaline.

The graph below shows the changes in the temperature of ice when it is heated from -20 °C to 100 °C.
Heat curve for ice. The graph shows the changes in the temperature of ice when it is heated from negative 20 degrees Celsius to 100 degrees Celsius. The label for the x-axis reads 'Addition of heat over time.' The label for the y-axis reads 'Temperature (degrees Celsius).' There are labels on the graph (from 'A' to 'E') that designate significant events while applying heat to the ice. Portion AB has a slight incline while increasing the heat from negative 20 degrees to 5 degrees; portion BC stays at 5 degrees for a while; portion CD steadily increases in temperature from 5 degrees to 100 degrees over a significant period of time; portion DE stays at 100 degrees for a while.
