Determine y for the following equation: log(9/8)=y

Chemistry
1 answer:
zalisa [80]3 years ago
8 0
Log(x) can mean log to the base ten (especially in highschool) or natural log (in college).

So solving for y in log(9/8)=y is just an evaluation of log(9/8).

Either
y=log_{10}(9/8)=0.05115 to 5 decimals, or
y=log_{e}(9/8)=0.11778 to 5 decimals
depending the context of the question.

Assuming all other conditions remain the same, which of the following will cause an object's density to increase?
Elanso [62]

Taking into account the definition of density,  assuming all other conditions remain the same, increasing mass will cause an object's density to increase.

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. That is, density is a quantity referred to the amount of mass contained in a given volume.

Density is an intensive property since it does not vary with the amount of substance.

Since density is the relationship between the mass and the volume of a substance, its calculation is defined as the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

In the previous expression it can be observed that the density is inversely proportional to the volume: the smaller the volume occupied by a certain mass, the greater the density.

On the other hand, density is directly proportional to mass: the greater the mass, the greater the density.

Finally,  assuming all other conditions remain the same, increasing mass will cause an object's density to increase.

A chemical reaction occurring in a cylinder equipped with a moveable piston produces 0.601 mol of a gaseous product. If the cyli
netineya [11]

Answer:

4.33 L

Explanation:

Assuming ideal behaviour and that all 0.300 moles of gas reacted, we can solve this problem using Avogadro's law, which states that at constant temperature and pressure:

  • V₁n₂ = V₂n₁

Where in this case:

  • V₁ = 2.16 L
  • n₂ = 0.601 mol
  • V₂ = ?
  • n₁ = 0.300 mol

We <u>input the given data</u>:

  • 2.16 L * 0.601 mol = V₂ * 0.300 mol

And <u>solve for V₂</u>:

  • V₂ = 4.33 L

4. How is the coordination number determined?
balandron [24]
A coordination number can be determined by the usage of an atom towards a molecule from seeing how many numbers of atoms would have to be combined together in an atom.
