Answer from: Osmin

The correct answer is :'Atoms must balance positive and negative particles'.

Explanation:

Scientist, J.J. Thomson from his experiment put forward following postulates regarding the structure of a atom:

An atom is made up negatively charged particle named as electron.An atom resembles a sphere of positive charges in which electrons are present inside the sphere.The magnitudes of positive and negative charges are equal which makes an atom an electrically neutral specie.

Hence, he can conclude from his experiment that :Atoms must balance positive and negative particles.

Answer from: shauntleaning

J.J. Thomson concluded that atoms must balance positive and negative particles.

Explanation: Model given by J.J. Thomson was Plum Pudding Model. This model was made in the course for the discovery of electron.

In the model, he said that the atom is a sphere carrying positive charge and the electrons having negative charge are embedded in it to balance the positive charge. The electrons are like plum in the pudding which are embedded in it.

Hence, he concluded that the atom is neutral which means that atoms must balance positive and negative particles.

Answer from: Quest

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.
