Answer:
To find the number of neutrons we would subtract the number of protons from mass number of an atom.
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
For example:
The mass number of carbon is 12 amu and it has six protons thus to find the number of neutrons we would subtract the 6 from 12 and get number of neutrons.
12- 6 = 6 neutrons
Answer:
Positively Charged
Explanation:
The is a group XVI and period 4 element of the periodic table with similar physical and chemical to that of tellurium and sulfur. Selenium exist in different allotropic forms, which have different solubility including selenate, selenite and selenium in elemental form
The Se ion in selenate has a positive charge of +6, while the selenate ion has a charge of -2
The Se ion in selenite has a charge of +4, while the selenite ion has a negative charge of -2.
The charge of Se in elemental selenium is 0.
Answer: 139.57 L
Explanation:
Through Charles' Law, we know that volume and temperature have a proportional relationship meaning that if we increase the temperature, the volume will also increase. We can use the following formula: (V1/T1) = (V2/T2)
The equation of Charle's law requires temperature to be in ubnits of Kelvin.
So to find the new temp in kelvin, we use T + 273 so the two temps are 523 and 1123. Now we can plug in our values into the formula
(65/523) = (x/1123)
x= 139.57 L
