Answer:
There would be three Lithium atoms per one Nitrogen atom.
3:1
Li3N (Lithium Nitride)
Explanation:
Group 15 elements usually have 5 valence electrons, and every atom wants to have a full valence shell of valence electrons. So, nitrogen can get three electrons from each Lithium atom in order to get a full octet.
Answer:
2–methylpropene.
Explanation:
To successfully name the compound given in the question, we must observe the following:
1. Determine the functional group of the compound.
2. Locate the longest continuous carbon chain. This gives the parent name of the compound.
3. Identify the substituent group attached and locate it's position by giving it the lowest possible count.
4. Combine the above to obtain the name of the compound.
Now, let us determine the name of the compound. This is illustrated below:
1. The functional group of the compound is the double bond i.e the compound is an alkene.
2. The longest continuous carbon chain is 3 i.e propene since it is an alkene.
3. The substituent group attached is methyl i.e CH3. In this case, we'll start counting from the side of the double bond being the functional group. Therefore, the methyl group i.e CH3 is at carbon 2.
4. Therefore, the name of the compound is:
2–methylpropene
Answer:
Her Eid per Ruth Jααte Hαin wo Humse,
αb bαtαo Hum Eid Mαnαye yα unko.
ہر عید پر روٹھ جاتے ہیں وہ ہم سے
اب بتاؤ ہم عید منائے یا ان کو
ik ishq ka gam aafat aur us pe ye dil aafat
ya gam na diya hota ya dil na diya hota
bas ek jhijhak hai haal-e-dil sunaane mein,
ki tera bhi jikr aaega mere is phasaane mein.
kya kahoon kis tarah se jita hoon
gam ko khaata hoon aansoo pita hoon
Answer:
2.123x10⁻⁴ M (mol/L)
Explanation:
First, we are considering the molar mass for each element, a data we obtain from the periodic table:
Ca= 40
S= 32
O= 16
Then, for CaSO₄, the molecular mass is 136 g per mol
As we dissolve 0.00101 g of this salt, we are going to convert this mass in moles units:
1 mol CaSO₄=136 g → 0.0101 g=7.43x10⁻⁵ mol
We finally obtain the concentration for the 350 ml, having in mind that it should be in mol/L:
350ml=7.43x10⁻⁵ mol
1000ml (1L)=2.123x10⁻⁴ M , where M=mol/L
A molecular property of the Group 6A(16) hydrides changes abruptly down the group. This change has been explained in terms of a change in orbital hybridization can see a similar difference in Group 15 as well where the same thing influences stability through bond strength (decrease in bond dissociation enthalpy down the group).
We can see a similar difference in Group 15 as well where the same thing influences stability through bond strength (decrease in bond dissociation enthalpy down the group). The change is a significant decrease in \textbf{bond angle}bond angle. Down the group we're observing increase in size as well as decrease in electronegativity which causes position of bond pairs of electrons to shift more and more away from the central atom. That then causes a decrease in repulsion between bonded pairs which results in a decrease in bond angle hydrides.
