Is ZnO Amphoteric?
Yes, Zn is not highly electro positive. So, in ZnO molecule Zn gets a small partial positive charge and O gets a small partial negative charge. Thus, it can accept the lone pairs as well as donate the lone pairs and can act as Lewis acid and Lewis base simultaneously. That's why ZnO is amphoteric.
How are electrically charged particles formed?
The basic charged particles are the proton (positive) and electron (negative). Normally the electrostatic force of attraction keeps them together within atoms and molecules, and in this state they are electrically neutral. Objects become charged when there is an excess or a shortage of electrons, produced for example by rubbing a dry cloth, or by the air currents in a thunder cloud.
Does water have polar molecules?
Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge () near the oxygen atom due the unshared pairs of electrons, and partial positive charges () near the hydrogen atoms. An electrostatic attraction between the partial positive charge near the hydrogen atoms and the partial negative charge near the oxygen results in the formation of a hydrogen bond. The ability of ions and other molecules to dissolve in water is due to polarity. For example, sodium chloride in its crystalline form will dissolve in water.
What configurations would form a bent molecule?
Any linear molecule in which the central atom has one or more lone pairs on it. Oxygen is the best example. The large negative charge on the lone pairs will force the electrons in the sigma bonds between the atoms away from itself, bending the structure.
How does polarity affect the property of water?
The shape of the water molecule is determined by the positions of the atoms in the molecule, and this shape has the electro-negative oxygen atom at one side of the H2O molecule, opposite from the two electro-positive hydrogen atoms at the other side.
What list of pairs of ion lye NaOH are correct charge?
Na: positive; OH: negative
What list pairs each element in table salt NaCL with the correct charge of its ion?
Na: positive; CL: negative
What is a zero pair?
The correct term isA zero pair is when one pairs a positive counter and a negative counter.HOPE THAT HELPED!!!**Calypso214
Which ordered pairs are in the second quadrant?
Ordered pairs that have a negative x and a positive y are in the second quadrant.
Why ZnO is amphoteric?
Zn is not highly electro positive. So, in ZnO molecule Zn gets a small partial positive charge and O gets a small partial negative charge. Thus it can accept the lone pairs as well as donate the lone pairs and can act as Lewis acid and Lewis base simultaneously. That's why ZnO is amphoteric.
How many factor pairs can you find for 12 if factors can be positive negative zero?
12 has three factor pairs, six if you count their negative counterparts.
Why the lone pair-lone pair repulsion is more than bond pair-bond pair?
In bonded pairs of electrons the repulsion of the negative charges is somewhat reduce by the positive charge of the bonded atom's nucleus. Lone pairs do not have this.
Is ZnO Amphoteric?
Yes, Zn is not highly electro positive. So, in ZnO molecule Zn gets a small partial positive charge and O gets a small partial negative charge. Thus, it can accept the lone pairs as well as donate the lone pairs and can act as Lewis acid and Lewis base simultaneously. That's why ZnO is amphoteric.
What are the factor pairs of NEGATIVE numbers?
So, when two negative numbers multiply, their product is a positive number (Remember the rule: minus x minus = plus). So, both the numbers in the factor pair should be either negative or positive to give a positive number as a product. For example: (-3 and -6) and (-2 and -9) form factor pairs for 18.
Is the product of 21 negative numbers and 23 positive numbers a positive number or a negative number?
It is a negative number, because every pair of negative factors makes a positive, and you have 10 pairs plus one left over.
How many 2 digit numbers have a difference of 90?
There are no pairs of 2-digit numbers with a difference of 90 if both numbers are positive or both negative. However, with one positive and one negative, there are 71 pairs.
