What happens to the ions when the drain is turned off? please help :] ❤️

kkurt [141]

Answer:

In a long channel MOSFET, the width of the pinch-off region is assumed small relative to the length of the channel. Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the drain current saturates.

Identify the type of reaction described in the sentence below. then, write a chemical equation. be sure to specify the states of

natulia [17]

Answer : The type of reaction described in the sentence is Synthesis or Combination

Explanation :

The balanced equation for the reaction between Phosphorous and Oxygen gas can be written as

$4P (s) + 5O_{2} (g) ------> P_{4} O_{10} (s)$

From the above equation we can see that there are two different reactants ( P and O₂ ) which are combining with each other to give a single product.

This type of reaction is known as Combination or Synthesis.

A general form of Synthesis reaction is given below.

$A + B ----> AB$

Here we can conclude that a synthesis / combination reaction is the one where 2 or more reactants combine together to give only one product .
