1) The type of bond in metalloids to metal is metallic bond.
Metallic bond is a type of chemical bond.
Metallic bond is formed between electrons and positively charged metal ions.
Metallic radius is defined as one-half of the distance between the two adjacent metal ions.
Metallic bond increace electrical and thermal conductivity.
Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.
2) The type of bond in nonmetal is covalent bond.
Nonmetals have low electrical and thermal conductivity.
Answer : The correct option is, (c) pyramidal
Explanation :
As we are given that a molecule in which the central atom forms three single bonds and has one lone pair that means the central metal atom has 3 bond pairs and 1 lone pair of electrons.
There are total 4 electron pairs. So, the hybridization will be
and the electronic geometry of the molecule will be tetrahedral.
But as there are three atoms or bonds around the central atom and the fourth position occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be pyramidal.
Hence, correct option is, (c) pyramidal
Nitrogen combine with hydrogen to produce ammonia
at a
ratio:

Assuming that the reaction has indeed proceeded to completion- with all nitrogen used up as the question has indicated.
of hydrogen gas would have been consumed while
of ammonia would have been produced. The final mixture would therefore contain
Apply the ideal gas law to find the total pressure inside the container and the respective partial pressure of hydrogen and ammonia:
Answer:
C. slightly basic
Explanation:
0-7 = acidic
7 = neutral
7-14 = basic
- Since the pH is just over 7, the answer would be slightly basic.

When studying the
movement of heat, what does the term "system" refer to any quantity
of matter of fixed identity of the chosen study. “Surroundings" refer to
the rest of the universe beyond the boundary of your chosen study or system.
