How does a positive ion become a neutral atom?
A positive ion can become a neutral atom by gaining electrons. When a positive ion gains one or more electrons, it becomes neutral because the negative charge of the electron(s) cancels out the positive charge of the ion.
Do non-metals become positive or negative as ions?
Non-metals typically become negative ions when they form ions because they gain electrons to achieve a full outer electron shell. This results in a negative charge due to the extra electrons present in the ion.
What could make G become negative at a given enthalpy and entropy?
Changing the temperature
When gaining electrons does an atom become negative or positive?
Gaining an electron that has a negative charge would negatively charge the atom.
What is the relationship between the viscosity of oils and temperature variations?
The viscosity of oils decreases as temperature increases. This means that as the temperature rises, oils become less thick and flow more easily. Conversely, as the temperature decreases, oils become thicker and flow more slowly.
When multiplying negative integers does it become negative or positive?
Negative times negative equals positive.
Is a negative subtract a negative a positive?
Yes. A negative subtracted by a negative is a positive. Just remember that two like signs become a positive sign, and two unlike signs become a negative sign.
When we lose something negative you become?
When we lose something negative you become positive.
What is the largest possible negative integer?
-1: Negative integers become smaller as their absolute value increases. Therefore, the first negative integer is the smallest. This answer assumes that -0 is excluded because 0 is neither positive nor negative.
How do you change a negative number into a decimal?
You divide the negative number by a positive number for it to stay positive. And you divide the negative number by a negative number for it to become positive.
Why multiplication of negative numbers equals positive?
When you multiply any number by a negative number you reverse its sign. So positive numbers become negative, and negative numbers become positive. That is the meaning of negative multiplication; it is reversal. This is similar to the way that adding a negative number has the same effect as subtracting a positive number. Negative is the opposite of positive.
Why does negative times negative give a positive result?
2 negatives equal a positive or if you multiply a negative by a positive it is larger negative if you multiply a negative and a negative it become positive because doing something negative times is getting bigger
Why does a positive ion bond with a negative ion?
To become more stable: positive+negative=neutral. Neutral is more stable than positive and/or negative.
What happens when a system of negative temperature is allowed to exchange heat with a system of positive temperature?
The described situation is only possible if the "negative" temperature is negative relative to some point above a thermodynamic temperature of zero; for example -20 °C is possible, but -20 K is not. With that said, the 2nd law of thermodynamics tells us that the system at negative temperature will warm up - with the temperature becoming less negative and even possibly becoming positive if the positive temperature system is warm enough. Likewise, the temperature of the positive temperature system will become less positive - possibly becoming negative if the negative temperature system is cold enough. The temperatures of the two systems will continue to adjust with the temperatures approaching each other until either the systems are separated to prevent further heat exchange or until they reach the same temperature (thermal equilibrium). All this assumes, of course, that the systems do not exchange mass, nor do they change composition (such as having a reaction going on within one system or the other).
What happens to a negative number with a positive exponent?
It will become a positive number.
How will temperature affect the spontaneity of a reaction with positive delta h and delta s?
For a reaction with a positive enthalpy change (ΔH > 0) and a positive entropy change (ΔS > 0), temperature plays a crucial role in determining spontaneity. The Gibbs free energy change (ΔG) is given by the equation ΔG = ΔH - TΔS. As temperature increases, the TΔS term becomes larger, which can help make ΔG negative, thus favoring spontaneity. Therefore, at sufficiently high temperatures, the reaction can become spontaneous despite the positive ΔH.
When you have a negative and positive in math does it become a negative?
It depends on what you do with the negative and positive. If you multiply or divide a positive number and a negative number, then the answer is negative. If you add or subtract a positive number and a negative number, the answer could be negative or positive depending on the numbers involved. If you put a negative sign in front of a positive number, the result is a negative number. If you put a positive sign in front of a negative number (like +(-7)), the result is still negative.
