Positive ions from a base and negative ions from an acid form a what?
A salt
What is happening in terms of ion when sodium hydroxide neutralizes hydrochloric acid?
This reaction is a strong base reacting with a strong acid to give a salt (NaCl) plus water. The positive Na ion combines with the negative Cl ion to form the sodium chloride. The hydroxyl group of sodium hydroxide combines with the hydrogen of HCl (hydrochloric acid) to form water. The charge on Na (+1) neutralizes the charge on Cl (-1) and the same things happens with H+ and OH-.
What type of ionic compound does the positive ion of a base and the negative ion of an acid combine to form?
salt
What is it called when an acid combines with a base?
Neutralization.
What is formed when strong acid combines with a strong base?
A salt is formed when a strong acid reacts with a strong base.
How do you make a negative exponent positive?
You can do it if you replace the base by its reciprocal.
When rewriting an exponential expression with a negative exponent and a positive base to an expression containing only a positive exponent does the sign of the base change?
No.
What is formed from a positive ion base and a negative ion from an acid?
A salt
Positive ions from a base and negative ions from an acid form a what?
A salt
Why you use negative source in emitter biasing?
to get the base- emitter junction forward bias we should connect the negative of the diode with the negative of the battery and the positive of the diode with the positive of the diode so we should connect negative source in the emitter

What is a ionic compound formed from the negative ions of and acid and the positive ions of a base?

Sodium hydroide completely dissociates into positive and negative ions and is therefore a?
Strong base
How do you change negative powers to positive?
You take away the negative sign and put 1 over the base with the (now positive) exponent. Example: x to the negative 2 becomes 1 over x to the 2nd.
Why negative numbers don't have logarithim?
The logarithmic function is not defined for zero or negative numbers. Logarithms are the inverse of the exponential function for a positive base. Any exponent of a positive base must be positive. So the range of any exponential function is the positive real line. Consequently the domain of the the inverse function - the logarithm - is the positive real line. That is, logarithms are not defined for zero or negative numbers. (Wait until you get to complex analysis, though!)
Will a negative exponent on a positive base ever result to a number less than 0?
No, it cannot.
When doing scientific notation is it negative if you move left?
No, if you shift the decimal point to the left, the exponent of base 10 is positive. The exponent of base 10 is negative if you shift the decimal point to the right.
