The given question is incomplete. The complete question is :
Welding is an industrial process that is used to join pieces of metal. A certain mixture of gases used in welding is composed of carbon dioxide and argon. The partial pressure of carbon dioxide is 0.080 atm and the partial pressure of argon is 0.24 atm. What is the total pressure of the mixture.
Answer: 0.32 atm
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : 
=total pressure of gases = ?
= partial pressure of carbon dioxide = 0.080 atm
= partial pressure of argon = 0.24 atm
putting in the values we get:
Thus the total pressure of the gases is 0.32 atm
Answer: energy=mgh 55*9.8*10.8= 5821.2 J <--- this can't be wrong, there's no other way to solve for it. set the potential energy equal to kinetic energy: 5821.2= 1/2...
Arsenic is a pure element. Elements (atoms) are the simplest building blocs excluding smaller elementary particles such as electrons, neutrons, quarks, protons etc.
This means that Arsenic can not be broken down any further by chemical change, only nuclear decay can cause the breakdown of large elements into smaller ones. Chemical change would be the combination of multiple elements into a compound or the decomposition of a molecule/compound into pure elements or smaller compounds.
<em>Here is the Answer I Hope this Helps:-</em>
<em>The closer the electrons are to the nucleus, the more tightly they are bound, thus increasing the electronegativity of the atom.</em>
