Answer- im pretty sure it's 2
Answer:
D. These elements have properties of both metals and nonmetals.
Explanation:
It can be concluded that the elements have properties of both metals and non-metals.
The elements that borders the ones described are both metals and non-metals. Most of these elements can be classified as metalloids.
On the periodic table, the elements around this region have properties of both metals and non-metals at certain temperature and pressure conditions.
Cl2O but the two is a little two after Cl
Answer:
(A)
Solubility will increase.
(B)
Solubility will decrease.
(C)
Solubility will decrease.
Explanation:
a) According to Le Chatelier's Principle when a change is introduced in a reaction system at equilibrium, the system responds by the reaction shifting in the direction to counter the change introduced.
When the change introduced is addition of acid, some
are consumed due to it and the system would respond by reaction shifting towards creation of more
in the system by increased dissolution. Thus solubility increase.
(b) When
are added, the reaction shifts to counter the change introduced of increased
by shifting to side that decreases the increased
. That happens by reaction shifting towards some
precipitating back. Hence solubility decreases.
(c) The change introduced is addition of
which will be countered by reaction shifting to side that decreases increased
, which happens by some
precipitating back. Hence solubility decreases.
Answer:
Molecules are made of two or more atoms
Molecules are made of atoms of the same element or different elements.
Molecules range in size.
Explanation:
A molecule is formed whenever two or more atoms combine. Hence we can define a molecule as a combination of two or more elements that are combined chemically and can not be separated by any physical means.
Molecules may be composed of the same atoms as in O2, F2 etc or different atoms as in CO2, H2O, etc.
The sizes of molecules differ. Some molecules are quite small in size while others are quite large in size.
