Answer:

88.46%

Explanation:

Percentage yield is actual/theoretical * 100

138/156 * 100 = 88.4615385

Why do you think many metals are good at conducting electricity?<br> Hurry, please!!!
umka2103 [35]
Answer. Metals are excellent conductors because the atoms in a metal form a matrix through which their outer electrons can move freely. Instead of orbiting their respective metal atoms, they form a "sea" of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions

This patient has a bone density of 820mg/cm3. What is the volume of a 25g sample?
mamaluj [8]

<u>Answer:</u> The volume of bone for given sample is 30.49cm^3

<u>Explanation:</u>

To calculate volume of a substance, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

Density of bone = 820mg/cm^3=0.82g/cm^3      (Conversion factor:  1 g = 1000 mg)

Mass of bone = 25 g

Putting values in above equation, we get:

0.82g/cm^3=\frac{25g}{\text{Volume of bone}}\\\\\text{Volume of bone}=30.49cm^3

Hence, the volume of bone for given sample is 30.49cm^3

Rubbing alcohol or isopropanol can be described by the chemical formula C3H7OH. One milliliter of isopropanol has a mass of 0.76
SVETLANKA909090 [29]

A chemical property of isopropanol : D. Isopropanol is flammable.

<h3>Further explanation </h3>

There are changes that occur in the mater: physical changes and chemical changes

Classification uses the principle of the initial and final state of the substance.

Physical changes do not form new substances, so the properties of the particles remain the same.(size,volume,shape)

Example : boiling and freezing, just change its phase form from liquid to gas or from liquid to solid

 

Chemical changes/reaction form new substances(products) that are different from the initial substances(reactants)

Example : toxic, corroded

So :

  • the physical properties of isopropanol :

<em>mass, density, evaporation</em>

  • the chemical properties of isopropanol :

<em>highly flammable</em>
