Answer:
Phosphorus atoms can bond with oxygen atoms to form ester groups. These can bond with carbon atoms, yielding a large number of organic phosphorus chemicals. These are found in many important biological processes
Answer:
1.8 L
Explanation:
Given data:
Initial volume of gas = 4.2 L
Initial pressure of gas = 101 kpa
Final volume of gas = ?
Final pressure of gas = 235 kpa
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
101 kpa × 4.2 L = 235 kpa × V₂
V₂ = 424.2 kpa . L/ 235 kpa
V₂ = 1.8 L
So when pressure is increased the volume of gas becomes 1,8 L.
Answer: it's nonmetal
Explanation: Sulfur has characteristics of nonmetals. It does not have luster, it cannot conduct electricity, and it is brittle. On the periodic table, sulfur is in group 16/VIA, in the third period. The group is called the oxygen group or the chalcogens.
Explanation:
Lattice energy is defined as the energy released when formation of 1 mole of an ionic compound occurs due to the combination of its constituent ions.
Also, lattice energy is inversely proportional to the distance between the cation and anion. And, when we move down a group then there occurs an increase in the atomic radii of the atoms.
This means that smaller is the ionic distance between the cation and anion, more will be the lattice energy between the atoms.
Hence, given compounds are ranked from largest to smallest lattice energy as follows.
> CaO > > LiBr
