What is boiling point?

Boiling point is the temperature at which a liquid changes its state from liquid to gas by vaporizing, usually at a constant temperature and pressure.

At the boiling point, the vapor pressure of the liquid becomes equal to the pressure of the atmosphere or the external pressure applied to the liquid surface, causing bubbles of vapor to form within the liquid and rise to the surface.

Explanation:

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL

Answers

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

the correct answer is A 4.8 mL

Why is it easier for most metal elements to gain electrons rather than to lose them?
PROPER EXPLANATION

Answers

Because it is easier for metals to shed their valence electrons and form cations for a stable configuration, they have comparatively few chances of acquiring electrons.

The metals usually complete their octet in each reaction. The outermost electron shell often contains more electrons in metals. Metal atoms lose electrons when they interact with other non-metals because the energy of an electron in its outermost shell is very weak.

Metals often have low ionization energy because their electrons are positive in nature. Metals lose their electrons and trade them with non-metals to achieve a stable configuration.

Blake is using a screw to hang on a picture in his room. Which of the these is the best description of a screw?

A. A screw allows you to use less force because a screw acts like a pulley.

B. A screw allows you to use less force because a screw acts like an inclined plane.

C. A screw allows you to do less work because a screw acts like a pulley.

D. A screw allows you to do less work because a screw acts like an inclined plane.

Answers

When using a screw to hang a picture, it is important to understand its function. The best description of a screw is option B - "A screw allows you to use less force because a screw acts like an inclined plane."

Screws are simple machines that have an inclined plane wrapped around a cylinder. This inclined plane is known as the thread. As the screw is turned, the thread pulls the screw into the material it is being screwed into, allowing it to hold on tightly.

Because of this design, screws are able to reduce the amount of force needed to hold an object in place. This is because the force applied to the screw is spread out over a larger area, making it easier to turn the screw and insert it into the material.

In conclusion, when using a screw to hang a picture or any other object, remember that it is an inclined plane wrapped around a cylinder, designed to reduce the amount of force needed to hold an object in place.

Answer: The answer is B! <3

Explanation:

When Blake puts a screw into his wall, it is a good description of an inclined plane. The threads of a screw act like an inclined plane to increase the distance over which you exert the input force. As the threads of the screw turn, they exert an output force on the wood, pulling the screw into the wood. So the answer is B. I hope this helped! :)

Explanation: i just did the test

Answer:

Explanation:

You are talking about the first 103 elements. An element is by definition identified with the number of protons in its nucleus, the so-called atomic number. Any atom with 6 protons is carbon, it cannot be anything else. So there cannot be any missing elements out to 103, as all of these elements have been confirm discovered by accepted scientific methods.

For example, here is a link to a CHEM Study film showing how transuranium elements (i.e. atomic number > 92 and man-made) can be separated from one another and verified as distinct.
