Answer:

Explanation:

Data Given

Formula of hydrazine = N₂H₄

Lewis structure of hydrazine (N₂H₄) =?

Solution:

Hydrazine (N₂H₄) contains 2 Nitrogen atoms and 4 Hydrogen atoms

Nitrogen atom have 5 valence electrons

Hydrogen have 1 valance electron

So it have 14 total number of valance electrons

N₂ H₄ = 2 (5) + 4(1) = 14 no. o electrons

it is a stable compound and obey octet rule for nitrogen and duplet rule for hydrogen by sharing of electrons.

To draw the Lewis Structure

Put the 2 nitrogen in center and draw the Hydrogen on the outside

Put the 2 hydrogen on out side of each of the nitrogen
Then draw the 2, 2 valence electrons between atoms that form chemical bond
So we will draw total 14 electrons in the structure
then we count electrons around each atom of nitrogen and hydrogen that it have 8 and 2 electrons to complete its octet and duplet respectively

The element californium (cf) sells for $1000 per µg. assuming 6.02 x 1023 atoms of cf have a mass of 251 grams, how many atoms o

Answer:- $2.40*10^1^0atoms$

Solution:- It is a simple unit conversion problem. We could solve this using dimensional analysis.

We know that, 1 US dollar = 100 cents

1 cent = 1 US penny

So, 1 US dollar = 100 US pennies

$1g=10^6\mu g$

Let's make the set up starting with 1 penny as:

$1penny(\frac{$1}{100pennies})(\frac{1\mu g}{$1000})(\frac{1g}{10^6\mu g})(\frac{6.02*10^2^3atoms}{251g})$

= $2.40*10^1^0atoms$

Therefore, we can bye $2.40*10^1^0atoms$ of Cf in one US penny.

Which measurement, temperature or volume, limits the precision of the data obtained in the experiment? explain?

GrogVix [38]

The answer is volume that is volume limits the precision of data obtained in an experiment .

As while pouring of the liquids, we control the volume, but it can have been off. And this could results in the wrong mole to mole ratio.Thus it limits the precision, So the answer is that volume limits the precision of data obtained in an experiment .

What is an ion? What are the two ways in which an ion can be made?

denpristay [2]

Answer: Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the ...
