Which of these is a physical property?A. Malleable
Ok so O3 has a greater electronegativity and is taken into account first, -2*3=-6, so As has to equal 6/2=3, so As has a +3 oxidation number here
Answer:
The controlled variable of an experiment is the one thing that stays the same in an experiment.
Explanation:
An example would be : if I have two pennies, both dunked in water, but than I change one to be dunked in vinegar, the one dunked in water still is the constant or the controlled variable.
Answer : The reactant acid and conjugate base in this reaction is,
and
.
Explanation :
Conjugate acid : A species that is formed by receiving of a proton
by a base is known as conjugate acid.
Conjugate base : A species that is formed by donating of a proton by an acid is known as conjugate base.
The given chemical reaction is,

In this reaction,
(base) react with
(acid) to give
(conjugate acid) and
(conjugate base).
Therefore, the reactant acid and conjugate base in this reaction is,
and
.
Below picture contains the given models.
Answer: Option-B is the correct model.
Explanation: Solid is a state of matter in which the particles are closely packed, has definite volume and shape. Like liquids they don't flow, either they occupy the volume of container as that occupied by both gases and liquids. The inter-molecular forces between solid particles are very strong as compared to liquids ans gases. So, the model B has a particles very closely packed to each other.
