Answer: No
Explanation:
A periodic table can be defined as the table in which the row of chemical elements are present. All the elements of the row have same number of electron shells.
The arrangement of elements is based on atomic numbers, electron shell model and other chemical properties. The elements are placed in increasing order of atomic number.
This table does not give information about the occurrence of the elements.
Answer:
. A homogeneous mixture of a solid in a gas
<h3><u>Question</u><u>:</u><u>-</u></h3>
In which one element replaces a similar element in a compound?
<h3><u>Answer</u><u>:</u><u>-</u></h3>
A single-replacement reaction
<h3><u>Explanation:</u><u>-</u></h3>
A single-replacement reaction is a reaction in which one element of a compound is replaced by another.
To determine how much water can form would depend on what the acetic acid is reacting with. However, a very common reaction of acetic acid that leads to the formation of water is the condensation that occurs during the esterification process. We can react acetic acid with an alcohol, such as methanol, and form the ester and water.
CH₃CO₂H + CH₃OH → CH₃CO₂CH₃ + H₂O
The mole ratio of water to acetic acid is 1:1. We can now use the mass of acetic acid to find the moles, which we can convert to moles of water:
5.10 g CH₃CO₂H / 60 g/mol = 0.085 mol CH₃CO₂H x 1 mol H₂O/1 mol CH₃CO₂H = 0.085 mol H₂O
0.085 mol H₂O x 18 g/mol = 1.53 g H₂O
In the reaction provided, assuming the reaction goes to completion, 5.10 g of acetic acid can form 1.53 g of water.
Answer:
Density
Explanation:
Intensive properties are those properties that do not depend on the size of the system or on the amount of matter in the system.
If materials are being sorted out for recycling, then materials can be sorted in accordance with their different densities and packed as such, this is quite a convenient way of sorting out the materials for recycling, hence the answer above.
