Answer: 26.54 grams
Explanation:
To calculate the moles :
![\text{Moles of lithium nitride}=\frac{12.87g}{34.83g/mol}=0.369moles](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20lithium%20nitride%7D%3D%5Cfrac%7B12.87g%7D%7B34.83g%2Fmol%7D%3D0.369moles)
is the limiting reagent as it limits the formation of product and
is the excess reagent
According to stoichiometry :
As 1 moles of
give = 3 moles of ![LiOH](https://tex.z-dn.net/?f=LiOH)
Thus 0.369 moles of
give =
of ![LiOH](https://tex.z-dn.net/?f=LiOH)
Mass of ![LiOH=moles\times {\text {Molar mass}}=1.108moles\times 23.95g/mol=26.54g](https://tex.z-dn.net/?f=LiOH%3Dmoles%5Ctimes%20%7B%5Ctext%20%7BMolar%20mass%7D%7D%3D1.108moles%5Ctimes%2023.95g%2Fmol%3D26.54g)
Thus 26.54 g of
will be produced from the given mass.
Answer:
decomposition reaction.
Explanation:
It is a decomposition reaction as potassium chlorate compound breaks to form potassium chloride and oxygen. This reaction requires heat as source of energy to break down the compound so it is endothermic in nature.
Answer:
5 electron groups, see saw
Explanation:
During the formation of SF4, the sulfur atom usually bonds with each of four fluorine atoms where 8 of valence electrons are used. The four fluorine atoms have 3 lone pairs of electrons in its octet which will further utilize 24 valence electrons. In addition, two electrons are present as a lone pair on the sulfur atom. We can determine sulfur’s hybridization state by counting of the number of regions of electron density on sulphur (the central atom in the molecule). When bonding takes place there is a formation of 4 single bonds to sulfur and it has 1 lone pair. Looking at this, we can say that the number of regions of electron density is 5. The hybridization state is sp3d.
SF4 molecular geometry is seesaw with one pair of valence electrons. The molecule is polar. The equatorial fluorine atoms have 102° bond angles instead of the actual 120° angle. The axial fluorine atom angle is 173° instead of the actual 180° bond angle.
Answer:
warm, dry downslope wind affecting Southern California - Santa Ana wind
a seasonally changing wind- monsoon
wind blowing from a valley up a mountain slope - valley breeze
generated by cold thunderstorm downdrafts - haboob
Explanation:
The Santa Ana wind occurs in early autumn. They bring hot and dry weather to areas around the South-West coast. They move at high speeds, affecting most parts of Southern California.
Monsoon is a seasonal wind that blows across Southern Asia. It usually blows in summer. It is a a seasonally changing wind.
Valley breeze is an example of convection current in nature. It is produced by rapid warming of the valley floor leading to the expansion of air making it to flow up the slopes. At night, radiation from the surface cools the slopes. This leads to the rise of cooler and denser air which drains into the valley.
Haboob is generated by cold thunderstorm downdrafts. It is associated with large sandstorms and dust storms.
