Answer: Option (d) is the correct answer.
Explanation:
At high temperature, there will be more collision between the molecules as a result more energy will generate. Thus, a wave can move quickly.
In case of solids, the particles are held more closely with each other. Therefore, when temperature is high then solid particles being closer can pass on the energy more quickly as compared to gases.
Thus, we can conclude that waves move fastest in high-temperature solids.
A molecule with a trigonal bipyramidal electron geometry must have a central atom with how many bonding and nonbonding electron groups around it Equatorial.
A molecule is made up of one or more atoms. If they contain multiple atoms, those atoms can be the same (the oxygen molecule has two oxygen atoms) or different (the water molecule has two hydrogen atoms and one oxygen atom). Biomolecules such as proteins and DNA are made up of thousands of atoms.
Water is a simple molecule with one oxygen atom bonded to two different hydrogen atoms. The bond is a polar covalent bond (polar bond) due to the high electronegativity of the oxygen atom.

Answer:
4
Explanation:
The weight will decrease.
Because the value of acceleration due to gravity is decreasing thus the weight of object will also decrease.
The question is in complete, the complete question is:
Which element has an outer electron configuration of s
2
p4
?
(A) Ca (B) Cr (C) Ge (D) Se
Answer:
(D) Se
Explanation:
The outer electronic configuration of an atom reflects the group to which it belongs in the periodic table. Each group has its unique outermost electron configuration and number of electrons found in the outermost shell of the atoms of elements in the group.
s
2
p4 is the unique outermost electron configuration of group 16 elements. Group 16 elements have six electrons in their outermost shell. If we consider the options, only Se is a member of group 16. Hence it is only Se that has the outermost electron configuration s
2
p4

Answer:
One mole of U238 ( 6.022 X 10^23 atoms) is 238 grams; one mole of U235 is 235 grams. The difference in molecular weight between a mole of U235 and U238 is 3 grams, the secret to enriching uranium.
