Answer:
Lots of things here
Explanation:
Ammonia structure is written as NH3
carbon monoxide is CO
make bonds between O2, so there is 2 oxygen atoms per group,
anything with multiple elements bonded is a compound, thus your answer for carnon monoxide isnt correct, it should be CO for written and it is a compound. Fix your formula for ammonia and also max a bond between those two oxygens because it is O2 not O,
Your structure for SO2 is improper aswell, there are only 3 elements in this molecule, and usually the one out in front of the molecule is the central atom (except hydrogen). So it would go O-S-O for the structure, with only two bonding groups.
H2O is the chemical formula of water. It means that each molecule of water is made up of two hydrogen atoms, indicated by the letter H, and a single oxygen atom, represented by the O. Water is a chemical substance with no smell, taste, or color.
Answer:
= -4.2°C
= 49.4°C
Explanation:
A Carnot cycle is known as an ideal cycle in thermodynamic. Therefore, in theory, we have:
|
| = 
Similarly,
|
| = |
| + |
|
During winter, the value of || = 20°C = 273.15 + 20 = 293.15 K and || = 1.5 kW. Therefore,
|| = 0.75( - )
Similarly,
|
| = 1 -
1.5/0.75*(293.15-) = 1 - (/293.15
Further simplification,
= -4.2°C
During summer, = 25°C = 273.15+25 = 298.15 K, and || = 1.5 kW. Therefore,
|| = 0.75( - )
Similarly,
|
| = 
- 1
1.5/0.75*( - 298.15) = (/298.15
Further simplification,
= 49.4°C
570/8.5=67.0 58... you only have to take the natural part, si the answer is 67 students
