Why can fluids flow but solids can’t?

Answer:

Because the particles don't move, solids have a definite shape and volume, and can't flow. LIQUIDS - This means that liquid particles are further apart and can move about more easily. Since the particles can move, the liquid can flow and take the shape of its container.

Answer:

Fluids can flow because their molecular structure is different. Instead of being tightly packed, like a solid, there are fewer molecules per unit in a liquid than a solid. This gives the molecules of a liquid space to move around, and it flows because liquids take the shape of their container(s). These molecules usually tend to bump into each other and this causes the liquid to move as well

Calculate the number of moles in 7g of nitrogen gas

Andru [333]

Answer:

Explanation:

7gN2 x $\frac{1 mol}{2(14.01) g}$

=0.2498mol N2

Nitrogen gas has the formula $N_{2}$ so therefore that means you would have to multiply the mass in the molar by 2. To solve for the number of moles you need to cancel out the grams, you do this by using the molar mass of nitrgoen gas. You get the value on in the denominator from the periodic table (atomic mass of element). The grams will cancel out, leaving you with the number of moles when you divide 7/2(14.01).

A sample of 10.0 grams of carbon dioxide gas is contained in a tank with a volume of 6.0 L so that the pressure inside the tank

Snezhnost [94]

Answer:

49°C

Explanation:

Let's apply the Ideal Gases Law in order to solve this question:

P . V = n . R . T

Pressure = 1 atm

Volume = 6 L

n = number of moles → 10 g. 1mol /44g = 0.227 moles

R = Ideal Gases Constant

We replace data: 1 atm . 6 L = 0.227 mol . 0.082 . T

6 atm.L / ( 0.227 mol . 0.082) = T

T° = 322 K

We convert T° from K to °C → 322 K - 273 = 49°C

One of the forms of asexual reproduction is the most common in algae

balandron [24]

Answer: In asexual reproduction, the genetic material of the parent cell doesn't combine with that from another cell. The simplest method of reproduction that algae employ is asexual binary fission, in which a cell splits into two, either at the equator or along its length.

Which substance is always a product when an Arrhenius acid in an aqueous solution reacts with an Arrhenius base in an aqueous so

svetoff [14.1K]

The answer is (2). The question only ask the production of acid reacts with base. The acid has H+ ion and base has OH- ion. When they react, the production will always contain H2O.
