Answer is: Identical particles were produced no matter which metal he used.

J.J. Thomson placed two oppositely charged electric plates around the cathode ray. He did experiments using different metals as electrode materials and found that the properties of the cathode ray remained constant no matter what cathode material he used.

Tomson concluded that atoms are divisible and that the corpuscles are their building blocks (atoms are made up of smaller particles).

J. J. Thomson discovered the electron in 1897.

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge.

With this model, he abandoned his earlier hypothesis (the atom was composed of immaterial vortices).

The label on a container of margarine lists "hydrogenated vegetable oil" as the major ingredient. what is the result of adding h
raketka [301]

Catalytic hydrogenation causes the oil to become saturated. So hydrogenated vegetable oil has fewer trans fatty acids and thereby less kinks. The greater the unsaturation (double bonds) the higher is the "kinks" in the fatty acid chains. Hydrogenated vegetable oil have higher melting point causing them to be solids at room temperature such as margarine. In the absence of double bonds (hydrogenated) the fatty acids pack tightly in a crystal lattice. Hydrogenated vegetable oil is likely to clog arteries.

Answer:

2Mg(s) +O₂(g) → 2MgO(s)

Explanation:

Mg(s) +O₂(g) → MgO(s)

When a chemical equation is balanced, the number of atoms of each element is equal on both sides of the arrow. We usually balance O and H last.

In this case, the number of Mg atoms is equal on both sides. Thus, let's move on to balance the O atoms. On the left side, there are 2 O atoms, while there is only 1 O atom on the left side. Thus, write a '2' in front of MgO.

Mg(s) +O₂(g) → 2MgO(s)

Now, the number of Mg atoms is not equal. Write a '2' in front of Mg to balance it.

2Mg(s) +O₂(g) → 2MgO(s)

The equation is now balanced with 2 Mg atoms and 2 O atoms on each side.

If 24.5 ml of base are required to reach the color endpoint of an acid/base titration what volume of base is actually needed
Burka [1]
The volume of base that is actually needed is 24.5 ml of base.
Titration is a chemical technique which is used in chemistry to find out the concentration of an unknown solution. A solution of known concentration is usually used to determine the concentration of the unknown solution. The known solution is usually added to a specific quantity of the unknown solution until the reaction is complete. An indicator is typically added to the unknown solution and the reaction is deem to be completed when there is a color change in the unknown solution.
Thus, the volume of the base that is required to reach the color end point is actually the base volume that is needed for the reaction.
