In Ray Bradbury's 1953 novel Fahrenheit 451, 451°F is said to be the temperature at which books, which have been banned in the
klio [65]

Answer : The temperature in degree Celsius is, 232.78^oC

Explanation :

The conversion used for the temperature from Fahrenheit to degree Celsius is:

^oC=(^oF-32)\times \frac{5}{9}

where,

^oF = temperature in Fahrenheit  

^oC = temperature in centigrade

As we are given the temperature in Fahrenheit is, 451

Now we have to determine the temperature in degree Celsius.

^oC=(^oF-32)\times \frac{5}{9}

^oC=(451^oF-32)\times \frac{5}{9}

^oC=232.78

Therefore, the temperature in degree Celsius is, 232.78^oC

Which of the following techniques can be used to separate a heterogeneous mixture into its component parts?
fredd [130]

Answer:

                  Separation by density

Explanation:

                    Mixtures are made up of two or more pure substances which tends to keep their individual identities. These components can be separated from each other by different physical techniques.

                    Mixtures are further classified as;

  (i)  Homogenous Mixture:

                                            In this type of the mixtures the components are uniformly mixed and their properties as well as composition as uniform throughout. Such mixtures are also called as solutions.

The physical methods used to separate these components from each other are distillation (taking heat and pressure into account), Solvent extraction, Magnetic separation, Chromatography e.t.c.

  (ii)  Homogenous Mixture:

                                            In this type of the mixtures the components are not uniformly mixed and their physical properties and composition are also not uniform.

The physical methods used to separate these components from each other are Filtration, Magnetic Separation, Centrifugation, Flotation e.t.c.

So, in given options the density can play role by settling the massive components of heterogenous mixture to sit at the bottom and separated

2C6H10 + 17O2 = 12CO2 + 10H2O
Ad libitum [116K]

Answer:

n O2 = 2.125 mol

Explanation:

balanced reaction:

  • 2C6H10 + 17O2 → 12CO2 + 10H2O

∴ n CO2 = 1.5 mol

⇒ n O2 = (1.5 mol CO2)*(17 mol O2/12 mol CO2)

⇒ n O2 = 2.125 mol
