What is the valency of water?
Zero. The valence of hydrogen is plus 1, and the valence of oxygen is minus 2. Water is H2O, i.e. each molecule of it consists of two hydrogen atoms combined with one oxygen atom. Adding the valences of the components, we obtain zero as water's valence (charge).
What is the valency of Sodium in Na2Co3?
0The valence of Na in this compound is +1 and of Carbonate it is -2However it is better to use: ionic charge or -number,So, when dissolved in water, you get:Na2CO3 -> 2 Na+ + CO32-
To keep them from reacting some highly reactive elements are stored in?
To keep highly reactive elements from reacting, they are often stored in inert gases such as argon or mineral oil. This helps prevent them from coming into contact with oxygen or water, which could lead to unwanted chemical reactions. Storage in a controlled environment can help maintain the stability of these elements.
What are the independent and dependent variables of adding salt water to boiling water?
The quantity of salt added to water is under your control and it will change the boiling point of water,i,e. the temperature of water. So quantity of salt is an independent variable while the temperature of water is dependent variable, when other factors are kept constant.
What is 3 places the water is stored?
streams , lakes , oceans , wells , bottles , bathtub , pipes ,sewers , and your body If you want where it's stored naturally, Its stored in Aquifers (underground), Atmosphere, Oceans, and Rivers.
How do you find out valency of mixture or compound?
To find the valency of a mixture or compound, you need to know the individual valencies of the elements involved. Valency is determined by the number of electrons an atom gains, loses, or shares to achieve a stable electron configuration. For example, in water (H2O), hydrogen has a valency of +1 and oxygen has a valency of -2, resulting in a compound with a total valency of zero.
How are group 1 elements stored?
Group 1 elements are typically stored in mineral oil or kerosene to prevent them from reacting with moisture and oxygen in the air. They are also stored under an inert gas such as argon to minimize contact with air and water vapor. Additionally, group 1 elements are often stored in sealed containers to prevent accidental exposure to moisture or oxygen.
Is kg an independent variable?
No, a Kilogram (Kg) is not an independent variable. An independent variable is any system that remains free from change If something else changes. We would therefore say a Kilogram is a dependent variable. The amount of Kilograms depends on the amount of fat, water, organs, etc stored.
What is the valency of h2o?
-1 hco3-1 all bases are - and most if not all the ones with hydrogen in front are -1 for example- hydrogen sulfate (hso4-1)or hydroxide (oh-1)
Which elements can store sound energy?
Sound energy can be stored in elements such as air, water, and solids like metal or wood. These elements can vibrate when sound waves pass through them, storing and transmitting the sound energy in the process.
Where is water stored first?
water is first stored in the sea
What are elements in substances?
Nitrogen: 78% Oxygen: 21% Noble gases: <1 Carbon dioxide COMPOUND: 0.04% Water Vapour COMPOUND: Variable
What is a dependnent variable?
A dependent variable depends on the independent variable. If you are doing an experiment about how temperature affects the heat of water then the independent variable would be the temperature, as that is what you are going to change, and the dependent variable the water as the temperature of the water depends on the temperature surrounding it.
How is the water stored on earth during the water cycle?
I don't think it can.Water is stored in several places in the water cycle:lakes, oceans, man made reservoirsground watercloudsetc.
What is the valency of water?
Zero. The valence of hydrogen is plus 1, and the valence of oxygen is minus 2. Water is H2O, i.e. each molecule of it consists of two hydrogen atoms combined with one oxygen atom. Adding the valences of the components, we obtain zero as water's valence (charge).
What are the dependent and independent variable in what is the water cycle?
independent variable is the water i dont know
