Answer:
prohibited because of germs that are on your phone.
Explanation:
Answer:
6 mol H, 9 mol O2
Explanation:
We can see that in water, there are 6 moles of hydrogen, and for oxygen, there is 9 moles
Answer:
Equation S= (°C + 117.3)/1.956 °S(25°C) = 72.25°S
Explanation:
To know the difference between the scales, we must initially know the length of our new scale compared to the scale in Celcius degrees, for this we add the absolute value of our melting point and the boiling point | -117.3 ° C | + | 78.3 ° C | = 195.6 ° C
Because our new scale will be divided into 100 equal parts we can know the unit value of each degree ° C concerning degrees ° S. 195.6 / 100 = 1,956 ° C / ° S
For a linear relationship of the scales, the crossing point at ° S = 0.00 is equal to -117.3 ° C. whereby we can clear our equation to know the temperature in degrees Celcius from ° S
°C= -117.3 + °S * 1.956°C/°S
Clearing °S we obtain
°S = (°C + 117.3)/1.956°C/°S
(ii)
In this new scale the temperature of 25°C will be readed as
°S = (25°C+117.3)/1.956°C/°S = 72.25°S
13 neutrons.
Mass=25
Number=12
Mass - Number= Amount of Neutrons
