Answer:
2py and 2pz orbitals
Explanation:
Each carbon atom still has two half-filled 2py and 2pz orbitals, which are perpendicular both to each other and to the line formed by the sigma bonds. These two perpendicular pairs of p orbitals form two pi bonds between the carbons, resulting in a triple bond overall (one sigma bond plus two pi bonds).
Answer:
Explanation:
All you need to know is the atomic mass of platinum, and Avogadro's number.
2.00g Pt divided by atomic mass gives you the moles of platinum, and multiplying by avogadro's number (6.022 x 10^23) gives you the number of atoms.
Atomic mass of platinum can be found on any periodic table.
Hope this helped.
The conglomeration of two quantities.
Two quantities that go together to become a new identity.
Here are two different definitions you can put in! Hope this helps! Please give brainliest❤️
The chemical formula of a compound express the atoms by which the molecule is formed and the ratio of the atoms in which they are combined.
The space filling model of a compound describe the electron density in the compound of each atom.
The ball and stick arrangement of a compound describe the way in which the molecules are present in three dimensions.
The structural formula state the number of atoms present in the molecule, the type of element or atom present in the molecule and the way in which they are arranged closely which is the bond.
Thus only the structural formula only will cover all the options as stated.
Answer: KI, LiBr, MgS,GaN
Explanation:
Ionic sizes are the deciding factor in lattice energy. The smaller the ion, the higher the lattice energy. Since K+> Li+ and I- is larger than Br-, LiBr will have a higher lattice energy. The size of the sulphide ion is much smaller than the nitride ion but the Gallium is much smaller due to lanthanide contraction hence the answer.
