Answer:
A
Explanation:
Carbohydrates are a class of of food that contains three chemical elements. All carbohydrates consist of the elements carbon, hydrogen and oxygen. These there elements form the building blocks for the carbohydrates class.
In fact, the chemical formula of carbohydrates is written in a way such that these three elements are the only elements present in a molecule of a particular carbohydrate
C.
They broke down materials by chemical means
Answer:
2AgNO3 -> 2Ag + 2NO2 + O2
K2CO3 -> K20 + CO2
I'm not quiet sure...possibly an ionic bond.
Answer:
The tabulated values at 120 C of <u><em>hfg = 2202.1</em></u><u> kJ/Kg </u>and <u><em>sfg </em></u><u>= 5.6 </u>
<u>kJ/Kg.K</u>
Explanation:
According to Clapeyron Equation :
Taking P2 at temperature 125 and P1 at 115 degree Celsius .
T = 120 + 273.15 = 393.15 K
P2 = 232.23 kPa and P1 = 169.18kPa
(these are experimental values given in the Data)
= 5.6131 kJ/Kg.K
The tabulated values at 120 C of <em>hfg = 2202.1</em> kJ/Kg and <em>sfg </em>= 5.6131
kJ/Kg.K
