Answer:
It does not always retain the properties of the substances that make it up
It requires heat energy to make
Explanation:
A compound is a chemical substance composed of two or more kinds of atoms or elements joined together in a definite grouping.
The properties of compounds are distinct from those of individual elements that are combined in its make up.
- To produce a compound, a chemical change must take place
- As with most chemical changes, heat is required to drive the change.
- So, to form compounds, some amount of heat is needed to cause the change.
Explanation:
given:
n=23.4mol R=0.0821LatmK^-1mol^-1
T=317K
P=719mmhg
760mmhg=1atm
719mmhg= 719/760
=0.95atm
PV=nRT
V= nRT/P
=23.4mol*0.0821LatmK^-1mol^-1*317K/0.95atm
=578.55L
V1M1c1 = V2M2c2
29 x 0.26 x 1 = V2 x 0.4 x 2
V2 = 9.425
Answer:
Magnesium
Explanation:
The element that could provide one atom to make an ionic bond with oxygen is magnesium.
Generally, most group II elements will form an ionic bond with oxygen with just one atom.
An ionic bond forms by the transfer of electrons from one specie to another.
Oxygen has a charge of 2-, to use one atom to form ionic bond with this specie, a magnesium atom with 2+ charge will bond with the specie.
This will form:
MgO
This is notable for other group II elements.
Answer:
![[Pt(NH_{3}_{2})Cl_{2}]](https://tex.z-dn.net/?f=%5BPt%28NH_%7B3%7D_%7B2%7D%29Cl_%7B2%7D%5D)
shows geometrical isomerism.
Explanation:
<u>Geometrical isomerism:</u>
<em>"Molecules having same molecular formula but the but difference in the arrangement of atoms."</em>
Cis and trans isomers are called geometrical isomers.
Among the given , shows geometrical isomerism.
The <em>cis </em>and <em>trans</em> forms of the are as follows.
