What are the number of protons, electrons, and neutrons in one atom of titanium?.

Olin [163]

Answer:

Protons: 22

Neutrons: 26
Electrons: 22

Explanation:

Titanium's atomic number is 22, meaning that the number of protons it has in its nucleus is also 22. # of electrons = # of protons, so the number of electrons is also 22. Titanium has an atomic mass of 47.867, but we can round up to 48. To find the atomic mass, we add up number of protons and neutrons. We know the number of protons as 22, so we subtract 22 from 48 and get a number of 26. Thus, the number of neutrons is 26.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Scientific equipments have been defined as the instruments and glassware that has been used in the scientific study and experimentation.

<h3>Equipments for heating the water</h3>

The water has been heated to the temperature of 85 degrees Celsius. The temperature has to be monitored thus, a thermometer has been used.

The water has been measured to be 1 L, thus the graduated cylinder, and beaker has been used for the measurement and heating of water.

The heat has been provided to the beaker by placing it on a hot plate.

Thus, the scientific instruments used to heat water to 85 degree Celsius has been graduated cylinder, beaker, thermometer, and hot plate. Thus, option B is correct.

What can you do to make the chicken egg float in the water?Explain your answer.(Science)

Goryan [66]

Denser salt water makes the eggs to float in the water.

<u>Explanation: </u>

Egg will always sink in water, as egg is denser than water.

But we can make it to float by means of adding excess salt to the water. Adding more salt to water makes it as denser than egg. Denser water makes less dense egg to float in water.

So, making the water as denser one leads to the floating of egg in the water.
