What does intrinsic mean in science

Chemistry
1 answer:
quester [9]3 years ago
5 0

An intrinsic property is independent of how much of a material is present and is independent of the form of the material, one large piece or a collection of small particles. Intrinsic properties are dependent mainly on the fundamental chemical composition and structure of the material.

Organisms are classified into different kingdoms based on?...
Naily [24]

Answer:

Food and cell type

Explanation:

Kingdoms are by far the most basic legal structure for living objects. Living objects are classified into realms depending on how they consume food, the kinds of cells that produce their bodies, and the total type of tissue in their bodies.

An experiment shows that a 236 mL gas sample has a mass of 0.443 g at a pressure of 740 mmHg and a temperature of 22 ∘C. What is
aleksley [76]

Answer:

49.2 g/mol

Explanation:

Let's first take account of what we have and convert them into the correct units.

Volume= 236 mL x (\frac{1 L}{1000 mL}) = .236 L

Pressure= 740 mm Hg x (\frac{1 atm}{760 mm Hg})= 0.97 atm

Temperature= 22C + 273= 295 K

mass= 0.443 g

Molar mass is in grams per mole, or MM= \frac{mass}{moles} or MM= \frac{m}{n}. They're all the same.

We have mass (0.443 g) we just need moles. We can find moles with the ideal gas constant PV=nRT. We want to solve for n, so we'll rearrange it to be

n=\frac{PV}{RT}, where R (constant)= 0.082 L atm mol-1 K-1

Let's plug in what we know.

n=\frac{(0.97 atm)(0.236 L)}{(0.082)(295K)}

n= 0.009 mol

Let's look back at MM= \frac{m}{n} and plug in what we know.

MM= \frac{0.443 g}{0.009 mol}

MM= 49.2 g/mol

Liula [17]

Answer: The temperature of the gas reduced to 400K.

Explanation:

Stated that ; The pressure remains the same, that is initial and final pressure equals 1atm.

Applying Charles Law

V1/T1 = V2/T2

Initial volume V1 = 1

Final volume V2 = 1/2 (halved)

Initial temperature T1 =800K

Final temperature T2 = ?

(1/800) = (1/2)/T2

T2 = 800/2

T= 400K

Therefore, when the volume is halved, the temperature reduced also to half ( 400K)

Explanation needed please!
VashaNatasha [74]

Answer:

Below

Explanation:

2) there are 28 protons in this isotope

     The number that is on the bottom of the "stacked pair" tells you how many protons are in this isotope. It is often represented by the variable Z.

3) there are 35 neutrons in this isotope

     Subtract the number of protons (28) from the top number

4) there are 28 electrons in the neutral element of Nickel

     If you were to look at the period table and find Ni, you would see that its atomic number is 28. This number tells us the amount of protons and electrons there are in that element.

5) 62.9296694 atomic mass units

     Just search it up (unless your teacher wants you to calculate it)

6) there are 92 protons in this isotope

     Again just look at the Z value to find the proton count

7) there are 146 neutrons in this isotope

     Subtract 238 - 92 = 146

8) there are 92 electrons in the neutral element of uranium

     Again just look at the periodic table and find U

9) 238.0507882 atomic mass units

10) 12C or carbon 12 is more likely to bond with oxygen that 14c carbon 14

     This is because 12C is more abundant at 98.93% than 14C

Hope this helps! Best of luck <3
