Answer:
C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + H₂O
Explanation:
When a forest burns and all that's left is some ash, most of the mass of the trees go to the atmosphere, in the form of carbon dioxide.
In a total combustion process of organic matter,<em> the two molecules produced are carbon dioxide and water. </em>(CO₂ and H₂O)
The equation for the combustion of glucose is:
C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + H₂O
Mendeleev's periodic table
Dmitri Mendeleev
Like many scientists working at the end of the 19th-century the Russian chemist Dmitri Mendeleev (1834-1907) was looking for ways to organise the known elements. Mendeleev published his first periodic table of the elements in 1869.
Features of Mendeleev's tables
Mendeleev arranged the elements in order of increasing relative atomic mass. When he did this he noted that the chemical properties of the elements and their compounds showed a periodic trend. He then arranged the elements by putting those with similar properties below each other into groups. To make his classification work Mendeleev made a few changes to his order:
he left gaps for yet to be discovered elements
he switched the order of a few elements to keep the groups consistent
Answer:
Molarity of solution = 0.77 (Approx.)
Explanation:
Given:
Moles of LiCl = 0.529
Volume of water = 687
Find:
Molarity of solution
Computation:
Molarity of solution = [Moles/Volume]1000
Molarity of solution = [0.529/687]1000
Molarity of solution = 0.77 (Approx.)
a) Two or more atoms held together with bonds make up a molecule. b) Pure substances are made of only one type of atom. c) At least two types of atoms are required to make a compound. d) Mixtures can be made of two elements, two compounds, or an element & a compound.
Answer : The question is incomplete, the complete question is attached in answer
To calculate the displacement by Ann's driving from north of her house to south;
we have the data as
In north - 10 km
in south - 5 km
total - 15 km
So we can calculate the displacement, which will be,
10 - 5 =
5 km.Hence, the displacement will be
5 km
