If the mass of a box is 140 g, and the volume is 8 cm3, then the density of the box = ? socratic.org

Chemistry
1 answer:
Ksivusya [100]3 years ago
4 0

Answer:

17.5 g/cm³

Explanation:

We can solve this particular problem by keeping in mind the <em>definition of density</em>:

  • Density = mass / volume

As the problem gives us both <em>the mass and the volume</em> of the box, we can now proceed to <u>calculate the density</u>:

  • Density = 140 g / 8 cm³
  • Density = 17.5 g/cm³

The density of the box is 17.5 g/cm³.

Naddika [18.5K]

Answer:

Mechanism for top reaction is combustion while the side product at bottom path oximes

Explanation:

Hydroxiamine is a reducing agent that requires high temperature to combust in it'd ageous state to produced oxime while water is eliminated. The reverse is the case because the production of water during combustion I does not yield the fight result as it can e very irritating.

Increased temperature stimulates the protons to become free to combust and react with 2 butene and other aldehyde during chemical reaction.

If 1.00 g of a hydrocarbon is combusted and found to produce 3.14 g of co2, what is the empirical formula of the hydrocarbon?
photoshop1234 [79]
The combustion reaction is as expressed,

                CxHy + O2 --> CO2 + H2O

The mass fraction of carbon in CO2 is 3/11. Hence,
       mass of C in CO2 = (3.14 g)(3/11) = 0.86 g C.

Given that we have 1 g of the hydrocarbon, the mass of H is equal to 0.14 g. 

     moles of C = 0.86 g C / 12 g = 0.0713
     moles of H = 0.14 g H / 1 g  = 0.14

The empirical formula for the hydrocarbon is therefore, CH₂.

Fill in the sentences below to explore the process by which a storm becomes a hurricane. some terms may be used more than once.
Reptile [31]

Answer:

The sentences which are made by the given sentences are as :

Wind speeds are below 38 miles per hour, this feature represents the tropical depression.

Explanation:

Here in the question it has been mentioned to form the sentences with the given one:

  • Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
  • A tropical disturbance leads to an array of clouds which are disorganized    also there are thunderstorms with no rotation or little rotation with it.
  • When the winds are blowing at a speed of 38 and 74 miles per hour then it is called as a tropical disturbance.
  • 74 miles per hour should be the blowing speed of storm in order to consider it to be a Hurricane.
  • When the storm reaches a tropical storm stage it gets its name.
  • All of the storms which get occurred from time to time, among them half or even all get converted into a Hurricane.

These are the sentences which are made by exploring the whole process and by which a storm becomes a Hurricane.
