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.
I hope it helps.
Have a great day.
Thomson in 1897 was the first to suggest that one of the fundamental units was more than 1,000 times smaller than an atom, suggesting the subatomic particle now known as the electron. Thomson discovered this through his explorations on the properties of cathode rays.
Answer:
Our planet's rotation produces a force on all bodies moving relative to theEarth. ... The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected.
Explanation:
Answer:
The volume would be 6,4 L
Explanation:
We use the Boyle Mariotte formula, according to which for a certain mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1 = P2xV2
V2= (P1xV1)/P2= (3,2 atm x 2, 00 L)/1,00 atm= 6,4 L
Answer:
A) The reaction mixture contains mostly products at equilibrium
Explanation:
For the general reaction
Reactants ⇌ Products
The equilibrium constant is
![K_{\text{eq}} = \dfrac{\text{[Products]}}{\text{[Reactants]}}](https://tex.z-dn.net/?f=K_%7B%5Ctext%7Beq%7D%7D%20%3D%20%5Cdfrac%7B%5Ctext%7B%5BProducts%5D%7D%7D%7B%5Ctext%7B%5BReactants%5D%7D%7D)
Thus, if K is large, the concentration of products is greater than that of reactants.
The reaction mixture will contain mostly products at equilibrium.
C) and E) are wrong. The equilibrium constant gives us information only on the position of equilibrium, not on how fast it is achieved.
