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

What observations will you look for to determine if a metal undergoes reaction?
ElenaW [278]
When a metal undergoes a reaction, especially with a nonmetal, you should look for the formation of salts or the formation of precipitates in the case the product is not soluble to water. Metals loses electrons to form positive ions which then reacts to nonmetals that are negatively charged ions.<span />
