If a gas has a mass of 468 grams and its density is 17 grams per liter, how much volume does it occupy?

Answers

Answer:

The answer is

27.53 Litres

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{Density} [/tex]

From the question

mass = 468 g

Density = 17 g/L

Substitute the values into the above formula and solve

We have

[tex]volume = \frac{468}{17} \\ = 27.529411[/tex]

We have the final answer as

27.53 L

Why do atoms always contain the same number of electrons and protons?

Answers

Answer:

An electron is a negatively charged subatomic particle and a proton is a positively charged subatomic particle. Positive charge(s) attract negative charge(s) and vice versa. The proton and neutron stay together and attract one another to give the atom an overall charge of zero (neutral). Which is the charge of an atom. When there is an unequal number of protons and neutrons an ion is formed. If the number of protons are more than the electron, a positively charged ion called cation is formed. On the other hand, if the number of electrons are more than the protons a negatively charged ion called anion is formed.

Answer:

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.

Why are some isotopes radioactive and some are not?

Answers

Answer: there are atoms that either have too many or too few neutrons or protons in their nuclei. This results in an imbalance between the jedi forces holding them together, which leads to an excess of internal energy. Such atoms are said to be unstable or radioactive.

yo someone please help meee The density of silver is 10.5 g/cm3. What is the mass (in kilograms) of a cube of silver that measures 0.69 m on each side?

Answers

Mass=volume x density

Mass of the cube of silver is 3,449.34 kg

First find the volume of the cube in centimeters because the density is in centimeters:

0.69 * 100 = 69 centimeters

Volume = Side * Side * Side

= 0.69 x 0.69 x 0.69

= 328,509 cm³

The density of a material is calculated by the formula:

= Mass / Volume

As you have the density already and the volume, you can get the mass:

10.5 = Mass / 328,509

Mass = 10.5 * 328,509

= 3,449,344.50 grams

A kilogram is 1,000 grams so the mass in kg is:

= 3,449,344.50 / 1,000

= 3,449.3445 kilograms

What neutral element has the electron configuration described by the Aufbau diagram above.​

Answers

Answer:

Aluminium.

Explanation:

The above electronic configuration can be written in a simplified form as shown below:

1s² 2s²2p⁶ 3s²3p¹

Next, we shall determine the number of electrons in the atom of the element as follow:

Number electron = 2 + 2 + 6 + 2 + 1

Number of electron = 13

Next, we shall determine the number of protons.

Since the element is in its neutral state,

The number of electrons and protons are equal i.e

Proton = Electron

Number of electron = 13

Proton = Electron = 13

Proton = 13

Next, we shall determine the atomic number of the element.

The atomic number of an element is simply the number of protons in the atom of the element i.e

Atomic number = proton number

Proton = 13

Atomic number = 13

Comparing the atomic number of the element with those in the periodic table, the element with the above electronic configuration is aluminium since no two elements have the same atomic number.

We speculateon how and when Robert Allard began taking morphine, and what induced Maggie McLean to turn Jim Crenfew down for a nincompoop like Edward Brewer. Somebody has seen the notice of Maggie's deathin a New Orleans paper. We think of it, but we cannot take it in. We see her as she was when she first came to Merry Point to visit, a frail, high-spirited girl who made us all indignant with her outrageoustreatment of Jim Crefew. We talk on like that until we have called to mind almost all the people who ever came here in the old days. We hold them in our minds until they seem to live again. I look up throughthe branches of the sugar tree to where a light burns dimly in one of the upstairs rooms. Girls might be dressing there for a party. At any moment, I may hear the rumbling. explosive laugh of Jim Crenfew.At such a time, none of us three will stop talking We keep up the illusion, with a name has a name there. Seeking to make the scene more complete, we cast about on the fringes of our enormous familyconnection What ever became of this cousin, or how was that person connected? It is then that Tom Rivers's name will be mentioned. Infrequently, I say. One or two summers will go by, and I may not hear hisname. And then it will be spoken, and I have always that start, half pleasure, half pride, and I realize that no matter whether I hear his name or not he is never out of my memoryThere is a curious thing I have observed. If you sit day after day, summer after summer, in a chair under the same tree, you will notice how the light falls under and through the boughs to strike always in thesame pattern. You notice how it falls that way year after year, changing only with the seasons, and you think how you might go away and suffer death or torture by fire or flood, and the light always at the samehour in that season will be creeping around the bolel of that beech treeIt is like that with me when I think about Tom Rivers. I cannot understand how it was that he disappeared, leaving nowhere any trace of his going. I sit here in the late afternoon, and the long lances of shadowstart from the garden fence and move slowly on, past the big sugar tree and past the beech tree, to halt for a moment at the little sugar tree that stands not fifty yards from my chairWhen they have moved past. I see that the hunched, dark shadow that seemed to me a rooster standing with his back to the western light is really only a clump of dog fennel. I see it happen like that almostevery afternoon, and with it comes always a fresh wonder at the restless, hurried movements of human beings. The light can fall like that evening after evening on some tree or flower, and yet a man that onehas known intimately can vanish as we always say of Tom Rivers, off the face of the earthUned by permissionToward the end of the first paragraph, the references to what goes on "in one of the upstairs rooms and to Jim Crenfew's explosive laugh suggest which of the following about the narrator?He wishes to alter the pastBThe past is very vivid to himcHe cannot tell reality from unalityMacBook Pro39 To create an effective study schedule, a student mustguess the amount of time needed for studying.O write down all activities and commitments.O allow the same amount of time each day for studying.O budget periods of time to study daily, even if it is interrupted.
