Why do ashes from fire have a much lower mass than the wood that was burned

Chemistry
1 answer:
tatyana61 [14]3 years ago
8 0

Answer:

because when you burn some wood you don't just get ash, you also get energies like thermal energy(heat), light and also some gaseous compound are produced (like CO2, SO2 etc) for the combustion reaction(a reaction where something is burnt in presence of O2). So the energy reserved in the wood are transformed into heat, light, other compounds and some turn into ash.

A planet orbiting the Sun will experience the largest gravitational force and greatest tangential speed when it is
Travka [436]

Answer:

A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.

To convert from liters/second to cubic gallons/minute, multiply the number of liters/second by 15.850 0 0.0353 00.2642 0 60
ivanzaharov [21]

Answer: 15.850

Explanation:

The conversion used from liters to gallons is:

1 L = 0.264172 gallon

The conversion used from sec to min is:

60 sec = 1 min

1 sec =\frac{1}{60}\times 1=0.017min

We are asked: liters/sec = gallons/min

liters/sec=\frac{0.264172}{0.017}=15.850gallons/min

Therefore, to convert from liters/second to gallons/minute, multiply the number of liters/second by 15.850.

What is molar mass......?
Savatey [412]

In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by its amount of substance. The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.

Hope this helped!

Good luck :p
