Here is the table of prefixes. Alkanes have the general chemical formula CnH2n+2. CH4 where n = 1 is called METhane and this means it has just one carbon atom. The more atoms you add the chemical formula changes. If you have 2 carbon atoms the formula will be C2H2x2+2 id est C2H6 (Ethane).
Answer:
Nothing is shown below!!!
Answer:
= 913.84 mL
Explanation:
Using the combined gas laws
P1V1/T1 = P2V2/T2
At standard temperature and pressure. the pressure is 10 kPa, while the temperature is 273 K.
V1 = 80.0 mL
P1 = 109 kPa
T1 = -12.5 + 273 = 260.5 K
P2 = 10 kPa
V2 = ?
T2 = 273 K
Therefore;
V2 = P1V1T2/P2T1
= (109 kPa × 80 mL × 273 K)/(10 kPa× 260.5 K)
<u>= 913.84 mL</u>
Answer:
The average kinetic energy of the particles in the mug decreases. The average kinetic energy of the particles in the coffee increases. Thermal energy from the mug is transferred to the coffee. Thermal energy from the coffee is transferred to the mug.
When 2 moles of potassium chlorate decompose, 3 moles of oxygen are produced.
