Answer:
The coldest temperature possible
Explanation:
Absolute zero = 0 K
A. is wrong. 0 °C = 273 K
B. is wrong. -210 °C = 63 K
C. is wrong. 32 °F = 273 K
E. is wrong. -196°C = 77 K
Carbon-Oxygen
We breathe in oxygen, we breathe out carbon dioxide.
Answer:
more drag is created because the air molecules are not moving out of the way of the airplane
Explanation:
Answer:
There will be produced 1.71 moles of B which contain 1.03×10²⁴ molecules
Explanation:
The example reaction is:
2A → 3B
2 moles of A produce 3 moles of B
If we have the mass of A, we convert it to moles and then, we make the rule of three: 29.2 g / 25.6g/mol = 1.14 moles
Therefore 2 moles of A produce 3 moles of B
1.14 moles of A will produce (1.14 . 3) / 2 = 1.71 moles of B are produced
Now we can determine, the number of molecules
1 mol has NA molecules (6.02×10²³)
1.71 moles have (1.71 . NA) = 1.03×10²⁴ molecules
The temperature when ice melts is 32 degrees Fahrenheit.
