Answer:
Factors that influence flow :
Flow patterns in a fluid (gas or liquid) depend on three factors: the characteristics of the fluid, the speed of flow, and the shape of the solid surface. Three characteristics of the fluid are of special importance: viscosity, density, and compressibility. Viscosity is the amount of internal friction or resistance to flow. Water, for instance, is less viscous than honey, which explains why water flows more easily than does honey.
All gases are compressible, whereas liquids are practically incompressible; that is, they cannot be squeezed into smaller volumes. Flow patterns in compressible fluids are more complicated and difficult to study than those in incompressible ones. Fortunately for automobile designers, at speeds less than about 220 miles (350 kilometers) per hour, air can be treated as incompressible for all practical purposes. Also, for incompressible fluids, the effects of temperature changes can be neglected.
Your answer is C in the direction that relieves the change
That is the definition of Le chatelierts principle.

We have that for the Question "how many atoms are in Na2CrO4" it can be said that The total number of atoms is
From the question we are told
how many atoms are in Na2CrO4
Generally
In identifying the atoms are in Na2CrO4 we must first look closely at the compound Na2CrO4
We have
Na=1
Cr=2
O=4
Therefore
The total number of atoms is
X=1+2+4
X=7 atoms

Explanation:
Matter is defined as the substance that has mass and occupies space.
This means every matter will have mass and every matter will also have volume as it occupies space.
Every matter is made up of number of atoms as these atoms are the small sub-units that combine together and constitute a matter.
Hence, the statement atoms and compounds are made out of matter is not true.
As density is mass present in per unit volume. Therefore, every matter will vary in density.
Thus, we can conclude that characteristics that define matter are as follows.
Answer:
The answer to your question is: a, b and c
Explanation:
A.) Matter has mass. this option is correct, matter is formed by mass.
B.)Matter has volume (takes up space). this option is correct, matter takes up space.
C.)Atoms and compounds are made out of matter. This option is correct, all atomsand compounds are made out of matter.
D.) All matter has the same density. This optio is wrong, matter of different elements or compounds have different density.
