Any chemical reaction such as combustion, oxidation, decomposition, cellular respiration, etc.
Tin (Sn), also known as stannum, is a silvery-white to grey solid metal. It is considered to have a smooth texture and a hardness of 1.5 on the Mohr's scale which is very soft. It is also odorless and inert which is why it is used in many packaging. Robert Boyle did studies on the oxidation of tin in the 1600s.
A clastic rock is a sedimentary rock consisting of broken pieces of rock like sand grains welded together ie often cemented together by such things as silica or a calcareous cement and also by compaction. Different types of sandstone like quartz sandstone, greywacke, arkose etc are clastic rocks.
Answer:
The entropy change of carbon dioxide = 0.719 kJ/k
Explanation:
Given:
1.5 m - 3 insulated rigid tank contains 2.7 kg of carbon dioxide at 100 kPa
The objective is to determine the entropy change of carbon dioxide
Formula used:
ΔS=
Solution:
On considering,
ΔS=
On substituting the values,
ΔS=
ΔS=0.719 kJ/k
Answer:
A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion.
Explanation:
Lithium, an alkali metal with three electrons, is also an exception to the octet rule. Lithium tends to lose one electron to take on the electron configuration of the nearest noble gas, helium, leaving it with two valence electrons.
