Answer:The correct option is, 100 ml Graduated cylinder.
Explanation:Graduated cylinder : It is measuring cylinder that is used to measure the volume of a liquid. It has a narrow cylindrical shape. The marked line drawn on the graduated cylinder shows the amount of liquid that has been measured.
Erlenmeyer flask : It is also called as a conical flask or titration flask. It is a laboratory flask that has flat bottom, a conical body and a cylindrical neck. It is commonly used for the titration.
Beaker : It is a type of laboratory equipment that has cylindrical shape and it is used for the mixing, stirring, and heating of chemicals.
As per question, the graduated cylinders are more accurate and precise than Erlenmeyer flasks and beakers.
The solar system is made up of the sun and everything that orbits around it, including planets, moons, asteroids, comets and meteoroids. It extends from the sun, called Sol by the ancient Romans, and goes past the four inner planets, through the Asteroid Belt to the four gas giants and on to the disk-shaped Kuiper Belt and far beyond to the teardrop-shaped heliopause. Scientists estimate that the edge of the solar system is about 9 billion miles (15 billion kilometers) from the sun. Beyond the heliopause lies the giant, spherical Oort Cloud, which is thought to surround the solar system.
Communication.
When people exchange ideas about science, they are communicating with one another to both share and obtain knowledge. Collaboration is a large part of this communication, as the exchange of these ideas often leads to new discoveries and inventions.
Answer:
The atomic radius of an element <u>increase</u> when you move from the top to the bottom of a family.
Explanation:
As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
As the size of atom increases the ionization energy from top to bottom also decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.
while in case of period atomic radius decrease as we move from left to right because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases
Answer:
120 mol Mg
General Formulas and Concepts:
