<span>Which
of the following best describes the electron cloud model?
THE ELECTRON CLOUD MODEL WAS DEVELOPED BY SCHRODINGER. IT STATES THE THE ELECTRONS ARE NOT PARTICLES MOVING AROUND THE NUCLEUS IN FIXED ORBITY BUT THEIR LOCATIONS CAN ONLY BE STATED BY A PROBABILITY DENSITY IN FORM OF CLOUD AROUND THE NUCLEUS.
THEN THE MAIN POINT OF THE CLOUD MODEL IS THAT THE ELECTRONS ARE NOT IN FIXED ORBITS AROUND THE NUCLEUS BUT THEIR LOCATION IS STATED BY A PROBABILITY FUNCTION THAT IS LIKE A CLOUD REGION.
A. It shows
that electrons usually carry a negative charge.
FALSE: ELECTRONS ALWAYS CARRY NEGATIVE CHARGE
B. It shows that
electrons remain in high-energy subshells.
FALSE: ELECTRONS OCCUPY THE LOWEST-ENERGY SUBSHELLS AVAILABLE UNLESS THEY ARE EXCITED (ABSORB ENERGY)
C. It shows that electrons
move quickly in circular orbits.
FALSE: ELECTRONS DO NOT MOVE IN CIRCULAR ORBITS.
D. It shows that the electrons within
an atom do not have sharp boundaries.
TRUE. THE IDEA OF A CLOUD IS A DIFFUSSE REGION WHERE IS A 90% OF PROBABILITIES TO FIND THE ELECTRON, AND THEY DO NOT HAVE SHARP BOUNDARIES.

Answer:
Acidic oxides, or acid anhydride, are oxides that react with water to form an acid, or with a base to form a salt. They are oxides of either nonmetals or of metals in high oxidation states.
Explanation:
In combustion energy is released so it is an exothermic process !!
the answer is 2nd one !!
<h2>Double displacement reaction:</h2>
A double displacement reaction is a type of chemical reaction where two compounds react, and positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
<h3>For example:</h3>
Na2S+2HCl→2NaCl+H2S
hope it's helpful :)
