The process that took place is called oxidation or burning where wood was burnt into ashes.
<h3><u>
Explanation:</u></h3>
Wood is an organic compound formed of different types of carbohydrates, proteins and lipids. These components do have carbon oxygen hydrogen as most abundant atoms and also has some amount of nitrogen, phosphorous, and other metal ions like magnesium, calcium etc.
When the logs were burnt, the chemical reaction took place between the atmospheric oxygen and the atoms present in the wood, forming different oxides. As carbon was the most abundant atom present, a huge smoke containing carbon dioxide and carbon monoxide evolved. The hydrogen became the water vapour, and other gases were also formed like nitrogen dioxide, sulphur dioxide etc. These gases went off into atmosphere. The rest that were left behind were mixture of unburnt part of wood as well as the solid metal oxides. There were unburnt particles of carbon mixed with them too.
Explanation:
Divide 67.6% by 201 of mercury
Divide 10.8% by 32 of sulfur
Divide 21.6% by 16 of oxygen
Then divide number by itself .
Example : Divide 2.97 by both sulfer moles and oxygen moles . Multiply by 2 to get whole number
It could be both A. and B. but most likely B. because the star can b big but have the same temperature as a smaller star.
Answer:
<h3>The answer is 31.4 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of metal = 4 cm³
density = 7.85 g/cm³
The mass is
mass = 7.85 × 4
We have the final answer as
<h3>31.4 g</h3>
Hope this helps you
