when an atom gains or loses an electron, it becomes an ion. Ions formed by the loss of an electron have a positive charge, and those formed by gaining an electron have a negative charge. Positive ions are called cations, and negative ions are called anions.
Given :
Rate = 75 m 1 s×60 s 1 min×1 h 60 m.
To Find :
Correct answer after conversion.
Solution :
We know, 1 min = 60 sec.
1 hour = 60 min = 60×60 sec = 3600 sec.
Putting value of min and hour in seconds , we get :
Hence, this is the required solution.
Depends on what you’re going for. i’d say aquifers. but you can drink from clean rivers
<u>Answer:</u> A chemical property is the characteristic property of a substance to chemically react or change in some way into a new substance.
<u>Explanation:</u>
A chemical property of a substance is determined by the chemical change.
A chemical change is defined as the change in the chemical composition of a substance resulting in the formation of new substance. It is usually an irreversible reaction.
Hence, a chemical property is the characteristic property of a substance to chemically react or change in some way into a new substance.
<span>As mentioned, the isomerization of cyclopropane to propylene is a first-order process with a half-life of 19 min at 500°c. A first-order reaction kinetic rates means that the rate is constant throughout the reaction.
Thus, the time it takes for the partial pressure of cyclopropane to decrease from 1 atm to 0.125 atm at 500°c is </span><span>57 minutes.</span>
