A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Why does the flow rate of a fluid with large particles increase?
NEED ANSWER ASAP!!!

Answers

Answer:

The viscosity of intestinal contents should define the mixing, diffusion and flow of nutrients and other materials in digesta (1–4). The viscosity of intestinal contents has been measured only after the removal of solid particles by centrifugation (5,6), under the assumption that particles or insoluble fibers in the diet do not affect the viscosity of gut contents (7). However, the complete removal of solid particles considerably reduced the coefficient of viscosity of pig cecal contents and changed the contents from a non-Newtonian to a Newtonian fluid in our recent study

A 5-liter sample of gas initially at 50°C is observed to expand to 5.5 liters when the temperature is raised to 100°C. After further increase in temperature, the volume is 6 liters. What is the approximate temperature (within 50 degrees) of the final state of the gas?
O 50°C
O 100°C
O 150°C
O 200°C

Answers

Answer:

150

Explanation:

.5 liter increase every temperature  50°C.

5 liter= 50 C

5.5 liter= 100 C

6 liter= 150 C

Answers

I believe your answer would be A.

Answer:

A

Explanation:

This is the answer because:

Determine the number of atoms of 25 g iron(II) chloride​

Answers

Answer:

3.56x10²³ atoms

Explanation:

To solve this question we need first to determine the moles of iron (II) chloride, FeCl₂, using its molar mass. Then, using Avogadro's number we can solve for the number of atoms:

Moles FeCl₂ - Molar mass: 126.751g/mol-

25g FeCl₂ * (1mol / 126.751g) = 0.1972 moles

Number of atoms:

1 mole of FeCl₂ are 6.022x10²³ molecules of FeCl₂, that means 0.1972moles are:

0.1972mol * (6.022x10²³ molecules / 1mol) = 1.188x10²³ molecules of FeCl₂

In 1 molecule of FeCl₂ there are 3 atoms (1 of Fe and 2 of Cl), in 1.188x10²³ molecules of FeCl₂ there are:

1.188x10²³ molecules of FeCl₂ * (3atoms / molecule) =

3.56x10²³ atoms

What kind of reaction is this?

Answers

Answer:

Single replacement

Explanation:

Chemical equation:

2Al(NO₃)₃ + 3Ca    →    3Ca(NO₃)₂ + 2Al

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

All other options are incorrect because,

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AD +CB

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

AB → A + B

Combustion reaction:

Reaction in substance react with oxygen and form carbon dioxide and water.

What makes a metal and a non metal most
reactive? Where in the PT will you find the most
reactive metal and the most reactive non metal.?

Answers

Answer:

Explanation:

The reactivity of elements in the periodic table is based on the number of electrons in there outermost shell. Elements (metals) that have few electrons in there outermost shell are highly reactive because it is easier to lose fewer number of electrons (in the outermost shell during a reaction) than to lose more electrons in the outermost shell - thus metals that have one electron in there outermost shell are most reactive and are more reactive than those that have two electrons in there outermost shell. Hence, metals in group 1 are the most reactive metals because they all have one electron in there outermost shell.

Non-metals that have fewer electrons to complete there octet configuration are highly reactive because it is easier to gain fewer number of electrons (in the outermost shell during a reaction) than to gain more number of electrons - thus nonmetals that have seven electrons in there outermost shell are more reactive than nonmetals that have six electrons in there outermost shell. Hence, nonmetals in group 17 are the most reactive nonmetals because they contain seven electrons and have just one electron left to complete there octet configuration.
