What are the meanings of positive and negative reduction potentials?
the meanings of positive and negative voltage
It has a potential difference between the positive and negative terminals?
It is a battery.
An is a positive or negative number assigned to an element to show its combining ability in a compound?
oxidation number
What is a negative - positive?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Why is gravitational potential always negative?
because gravity is a force that acts down on an object. In physics up is positive and down is negative
What are the meanings of positive and negative reduction potentials?
the meanings of positive and negative voltage
What does a reduction potential chart show?
How likely chemical species are to gain electrons and therefore, be "reduced". Reduction potential is measured in volts(V) and the more positive the reduction potential value, the more likely it will be reduced.
Which bacteria is amylase positive catalase positive cysteine desulhydrase negative nitrate reduction negative glucose positive lactose positive sucrose positive citrate positive?
bacillus subtilis
What is the relative standard reduction potential of the half cell in which reduction occurs?
more positive than the other half-cell
What is the relative standard reduction potential of the half-cell in which reduction occurs?
more positive than the other half-cell
What is a positive DC voltage?
A positive DC voltage is an electric potential where excess electrons will flow from negative to positive.AnswerYou appear to be mixing up potential difference (i.e. voltage) with potential. There is no such thing as a 'positive' voltage if you mean 'positive' in the sense of charge! 'Voltage' means 'potential difference', and you cannot have a positive or negative potential difference in this sense. You can only apply positive and negative in this sense to potentials.However, if you mean 'positive' in the sense of direction, then a positive voltage is one that is acting in the opposite direction to a negative voltage within the same circuit. For example, where two batteries have been connected in opposition.
The terminals of a diode are called the?
anode positive potential cathode negative potential
What is it called when positive and negative charges have a potential difference?
Voltage.
It has a potential difference between the positive and negative terminals?
It is a battery.
A more positive value for electrode potential means that the electrode is more likely to be a?
A more positive reduction potential (Eored) means that substance will be reduced, which occurs at the cathode. A more positive oxidation potential (Eoox) means that substance will be oxidized and occur at the anode.
Why the dc average voltage is having negative value?
Voltage is synonymous with 'potential difference', and cannot have a positive or negative value (in the sense of charge). So what you are describing is 'potential', which can. So, for example, a battery whose positive terminal is earthed or grounded will indicate a negative potential if a voltmeter is connected between earth and its negative terminal.
An is a positive or negative number assigned to an element to show its combining ability in a compound?
