el nitrogeno es un gas que se utiliza para conservar embriones,su temperatura es de -195,8ºc calcula esta temperatura en K y ºF
kipiarov [429]
Answer:
            -195.8 °C  =  77.35 K  =  -320.44 °F 

Explanation:

Temperature is commonly measured in following three scales;

1) Kelvin

2) Fahrenheit<span> 

3) </span>Celsius<span> 

Other scales are Rankine, Romer, Newton, Delisle e.t.c

Temperature given is -195.8 </span>°C. Degree Celsius is related to Kelvin and Fahrenheit as follow,

Celcius to Kelvin;
 
                          K  =  °C + 273.15
So,
                          K  =  -195.8 + 273.15

                          K  =  77.35 

Celcius to Fahrenheit;

                         
°F  =  °C × 9/5 + 32
So,
                         °F  =  -195.8 × 9/5 + 32

                         °F  =  -320.44

Determine the molecular geometry about the left carbon atom in ch3co2ch3.
Elanso [62]

Molecular geometry about the left carbon atom in CH₃CO₂CH₃ is tetrahedral.

The geometry around left carbon that is CH₃ is tetrahedral.

As the hybridization around left carbon is sp³ that shows its geometry should be tetrahedral and as there are 4 ligands around carbon and there is no lone pair present so the geometry is tetrahedral. So, the molecular geometry about the left carbon atom in CH₃CO₂CH₃ is tetrahedral.

The activation energy of a certain uncatalyzed reaction is 64 kJ/mol. In the presence of a catalyst, the Ea is 55 kJ/mol. How ma
Ksivusya [100]

Answer:

About 5 times faster.

Explanation:

Hello,

In this case, since the Arrhenius equation is considered for both the catalyzed reaction (1) and the uncatalized reaction (2), one determines the relationship between them as follows:

\frac{k_1}{k_2}=\frac{Aexp(-\frac{Ea_1}{RT} )}{Aexp(-\frac{Ea_2}{RT})}  \\\frac{k_1}{k_2}=\frac{exp(-\frac{Ea_1}{RT} )}{exp(-\frac{Ea_2}{RT})}

By replacing the corresponding values we obtain:

\frac{k_1}{k_2}=\frac{exp(-\frac{55000J/mol}{8.314J/molK*673.15K} )}{exp(-\frac{64000J/mol}{8.314J/molK*673.15K} )} =4.8

Such result means that the catalyzed reaction is about five times faster than the uncatalyzed reaction.

Best regards.
