Answer:
Proton: m= 1.6726x10⁻²⁷ kg
Neutron: m= 1.6749x10⁻²⁷ kg
Electron: m= 9.1164x10⁻³¹ kg
Explanation:
<u>We can calculate the mass of a proton, neutron, and electron using the following data:</u>
<em>mass of proton</em>: 1.00728 amu
<em>mass of neutron</em>: 1.00867 amu
<em>mass of electron</em>: 5.49x10⁻⁴ amu
<em>1 amu</em> = 1.66054x10⁻²⁷ kg
Now, the mass of a proton, neutron, and electron in kilograms can be calculated using the next relation:
For the proton:
For the neutron:
For the electron:

Answer:
It produces water.
Explanation:
H+ + OH- produces H2O.
It is a type of Neutralization reaction.
The gas molecules bump into each other more frequently. The gas could turn into a liquid if it is also combined with a lowered temperature.<span />
Answer:
37.9g of carbon 14 remains
Explanation:
The radioactive decay of an atom follows the equation:
Ln[A] = -kt + Ln[A]₀
<em>Where [A] is amount of isotope after time t, k is decay constant and [A]₀ initial amount of the isotope.</em>
<em />
We can find k from half-life using:
k = ln 2 / Half-Life
k = ln 2 / 5730 years
k = 1.2097x10⁻⁴ yrs⁻¹
Replacing in the equation all values:
Ln[A] = -1.2097x10⁻⁴ yrs⁻¹*2292yrs + Ln[50g]
Ln[A] = 3.635
[A] = 37.9g of carbon 14 remains

<span>Salt compounds are composed of ions that form a tightly packed and ordered network, which is called a crystal lattice. It is held together by electrostatic forces known as ionic bonding. Ionic bonding refers to the chemical bond between two oppositely charged ions - a cation and an anion. This type of bond forms when there is a large electronegativity difference between two atoms. </span>
