List 2 necessary conditions for rusting of iron rod?
Oxygen present Water Present Therefore leaving a metal unprotected will inevitably result in the rusting of it
Can zinc prevent rusting of iron?
It decreases rusting but doesn't totally prevent it.
Is rusting decomposition or synthesis?
Rusting is an oxidation and can be considered as a synthesis of an iron oxide.
How is rusting and transmutation related?
rusting and transmutation are the same because they are both dense. Therefore the attractive forces are determined by the air around it affects its rusting and transmutation.
What type of reaction occurs and how does the mass of the object after rusting compare with its original mass?
1. Rusting is an oxidation reaction of iron.2. The mass of an object increase after rusting.
What conditions encourage rusting?
Rusting requires conditions such as moisture and air (oxygen).
What are the conditions necessary for rusting?
The conditions necessary for rusting are water (or water vapour) and air, specifically Oxygen. If one condition is absent and the other is present then rusting would not occur but if both are present then rusting will occur
What are conditions required for rusting?
MOISTURE AND OXYGEN
What are the conditions for rusting to take place?
Water and oxygen are needed.
Under what conditions will rusting not occur?
Rust will not occur where it is dry and humid
Which two conditions need to be present for rusting to take place?
Air and water.
List 2 necessary conditions for rusting of iron rod?
Oxygen present Water Present Therefore leaving a metal unprotected will inevitably result in the rusting of it
What conditions will make iron and steel rust?
Rusting occur in iron when it reacts with oxygen and water...the less salts in the water the faster the rusting occurs...and the more percentage of oxygen the faster it rusts.
What kind of metal can survive underwater conditions?
any metal covered in zinc. zinc is used to prevent metals from rusting
Which one is a chemical change -rusting of iron or melting of iron?
Rusting is a chemical change. it forms one of the iron oxides depending the conditions. Melting is simply changing the form of the metal and of course it reverts to the solid state after the heat source is removed.
More reasons for rusting to occur?
Rusting can occur due to other factors such as exposure to moisture or water, presence of oxygen, and the presence of certain acids or chemicals in the environment. Additionally, the presence of impurities in the metal can also accelerate the rusting process. High humidity, salty environments, and contact with corrosive substances can all contribute to the rusting of metals.
Does oil help prevent iron from rusting?
no it just oils it+++ It will for a time but oil loses its efficacy as a protective fairly quickly, depending on conditions.
