Describe the location of the negative charges of the atom in j.j thompsons plum pudding model

iren2701 [21]

The location of the negative charges is evenly distributed throughout the entire atom.

J. J. 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 ( the negative charges of the atom) in 1897.

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge and evenly distributed throughout the entire atom.

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

Later, Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate.

How many grams of oxygen are needed to

Paraphin [41]

Answer:

The value is $M_{o} = 175 g$

Explanation:

Generally the reaction between oxygen and magnesium is

$2Mg_{({s})} + O_2_{(g)} \to 2MgO_{(s)}$

Generally from the law of mass conservation in a chemical reaction we have that

$M_{m} + M_{o} = M_{z}$

Here $M_{m}$ is the mass of magnesium

$M_{o}$ is the mass of oxygen

$M_{z}$ is the mass of magnesium oxide

$425+ M_{o} = 600$

=> $M_{o} = 600 - 425$

=> $M_{o} = 175 g$

What is the mass for 3.01*10 23 molecules h2o

Genrish500 [490]

M H₂O: 1g×2 + 16g = 18g


6,02×10²³ --------- 18g
3,01×10²³ --------- Xg
X = (18×3,01×10²³)/6,02×10²³
X = 9g

Consider the reaction of KOH with H3PO4 to form K3PO4 and H2O. If 5.38 g H3PO4 is reacted with excess KOH and 7.97 g of K3PO4 is

balu736 [363]

Answer:75%

Explanation:

First, the balanced reaction equation must be written out clearly as a guide to solving the problem. The molar masses of H3PO4 and K3PO4 are then calculated as they will be consistently required in solving the problem. The theoretical yield is obtained from the amount of H3PO4 reacted. Since 1 mole of H3PO4 yields 1 mole of K3PO4, 0.05 moles of H3PO4 yields 0.05 moles of K3PO4. The mass of K3PO4 is produced is then the product of 0.05 and it molar mass hence the theoretical yield. The % yield is calculated as shown.
