Why standard reduction potential of zinc is assigned as negative value whereas that of copper is positive value?
The standard reduction potential of a metal indicates its tendency to gain electrons and be reduced. Zinc has a standard reduction potential of -0.76 V, meaning it is more likely to lose electrons (oxidize) than to gain them, reflecting its position in the electrochemical series as a more reactive metal. In contrast, copper has a positive standard reduction potential of +0.34 V, indicating it has a greater tendency to gain electrons and be reduced. This difference in potentials highlights the relative reactivity and electron affinity of the two metals.
What is a negative - positive?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
When multiplying numbers what do you do with the positive and negative signs?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
When you divided a negative number by a positive number witth the answer be positive or negative?
A negative divided by a positive is negative. A negative divided by a negative is positive. A positive divided by a positive is positive. A positive divided by a negative is negative.
What does a positive and a neagive equal?

Is create a positive connotation?
The word has evolved to have many different meanings, and it can have either a positive or negative connotation
Why does the graphite rod act as a positive terminal where as the zinc casing a negative terminal?
The graphite rod acts as the positive terminal because it is the cathode where reduction reactions occur, while the zinc casing acts as the negative terminal because it is the anode where oxidation reactions occur. This is due to their differences in electrode potential and their roles in the electrochemical reaction process.
What does the reduction potential tell you about the stability of an element?
The reduction potential indicates how readily an element can gain electrons and be reduced; a higher (more positive) reduction potential signifies a greater tendency to accept electrons and thus indicates greater stability in its reduced form. Conversely, a lower (more negative) reduction potential suggests that the element is less stable when reduced and more likely to lose electrons. Therefore, elements with high reduction potentials are often more stable in their reduced states, while those with low potentials may be more reactive or prone to oxidation.
Which bacteria is amylase positive catalase positive cysteine desulhydrase negative nitrate reduction negative glucose positive lactose positive sucrose positive citrate positive?
bacillus subtilis
How do you give two denotative meanings for the word wear?
Negative or positive
Can resting membrane potentials be positive?
Resting membrane potentials are typically negative, ranging from -40mV to -90mV. A positive resting membrane potential would be unusual and could indicate an abnormal cellular state or malfunction.
According to the pattern of half-cell potentials what determines the polarity of a cell?
According to the pattern of half-cell potentials, what seems to determine the polarity of a cell?
Is debit positive or negative?
In case of Assets debit is positive which means increase in assets as well as for liabilities debit means reduction in liabilities but for expenses it is negative as it increases the expenses and reduces the profit

What is the definition for polarity?
Polarity refers to the positive or negative charge of a molecule or its parts. In chemistry, it describes the separation of charge in a molecule that has areas of differing electronegativity. A polar molecule has a positive end and a negative end.
Is a positive plus a negative make a positive or a negative?
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
