Answer:
Simply identify what elements are in a compound
Explanation:
For example in NaCl we have sodium (Na) and Chlorine (Cl)
In order to do this you would need to recognise the symbols for a certain element: O for oxygen; N for nitrogen; H for hydrogen etc.
Answer : The correct match is:
(1) → (k)
(2) → (j)
(3) → (f)
(4) → (d)
(5) → (e)
(6) → (g)
(7) → (a)
(8) → (i)
(9) → (l)
(10) → (c)
(11) → (b)
(12) → (h)
Explanation :
Physical property : It is defined as a change in which the identity of substance does not change.
Physical change : It is defined as something observed while keeping the identity of the substance the same.
Homogeneous mixture : It is defined as something made up of at least two different substances and is usually very difficult to separate. Even distribution of particles.
Heterogeneous mixture : It is defined as something made up of at least two different substances and easily separated by physical means. Unequal distribution of particles.
Chemical property : It is defined as something observed by changing the identity of a substance.
Compound : It is defined as a pure substance made up of at leat two different elements.
Matter : It is defined as anything that has matter and takes up space.
Chemical change : it s defined as a change that creates a new substance or compound.
Extensive property : It is defined as a property that change with the amount of matter present.
Mass : It is defined as the amount of matter contained in an object.
Volume : It is defined as the amount of space a substance takes up.
Intensive property : It is defined as a property that does not change with the amount of matter present.
Answer:
1) Capillary action
2) Cohesion
3)Miniscus
4) Adhesion
5) Viscousity
6) Surface tension
Explanation:
Intermolecular forces are forces that holds molecules together in liquid, these is possible by inter-molecular interactions that exist within the liquids.these forces includes forces such as Waals forces and hydrogen bonds.
When there is great inter-molecular forces, there will be high freezing point and boiling point . At a lower inter-molecular forces the boiling point becomes low too,which brings about great fluidity of the liquid. The liquid flow reluctantly where greater force exist in the liquid. Some of those factors used in characterizing which are;
1)adhesion,
2) surface tension,
3)capillary action,
4)cohesion,
5) meniscus,
6)viscosity.
Top right. Hope this helpssssssss
