What number represents the subscript in 5H2?
1.What number represents the coeffcient 5H2? 2.What does the corffcient 5H2?
Do you have to use subscript in chemical formulas?
Not every chemical formula requires subscript. For example table salt is NaCl, sodium chloride. No subscript. But most chemical formulae do require subscript, such as water, H2O.
The elements that make up a compound and the exact number of atoms of each element in a unit of the compound can be?
Subscript (:This is a subscript: (Na2) the "2" is the Subscript.
Which has a strong bond H2 or H2 plus?
H2+ has a stronger bond than H2. The addition of a positive charge to the H2 molecule increases the attraction between the two hydrogen atoms, resulting in a stronger bond.
Is H2 combustible?
Yes, H2 is extremely flammable.
In the equation 2 H2 plus O2 the H2 molecules are?
H is the atomic symbol for hydrogen, the 2 subscript means it is diatomic.
What are the di?
Diatomic elements consist of two atoms.The formula of these elements are always written with a subscript 2 in its symbol to indicate its molecular composition.examples: H2,O2.
What is H2 in science?
the subscript 2 after the H indicates that the hydrogen molecule contains two (2) atoms of hydrogen
What is the balanced chemical equation for sodium and hydrochloric acid reacting to produce sodium chloride and hydrogen?
Do not try this! 2Na +2HCl --> 2NaCl + H2 The last 2 should be a subscript.
What are the di-atomic elements?
Diatomic elements consist of two atoms.The formula of these elements are always written with a subscript 2 in its symbol to indicate its molecular composition.examples: H2,O2.
What number represents the subscript in 5H2?
1.What number represents the coeffcient 5H2? 2.What does the corffcient 5H2?
What do subscripts in chemical equations tell about the equation?
The subscript in the equation tells you how many atoms of that element there are in the reaction. For example: H20 --> H2 + O2 Before the reaction there are 2 hydrogen atoms and 1 oxygen (the subscript 1 isn't shown). After the reaction there are 2 hydrogen atoms and 2 oxygen atoms. Keep in mind that this is a skeleton equation and isn't balanced yet.
Why doesn't the 0xygen have a subscript?
Why doesn't the 0xygen have a subscript?
How do you subscript on a Dell?
ctrl = for subscript ctrl shift = for superscript
When solid sodium is added to liquid water it reacts with the water to produce hydrogen gas and aqueous sodium hydroxide what does the formula look like?
2Na + 2H2O--->H2+ 2NaOH Hydrogen gas is diatomic, therefore it requires a subscript of 2.
What is the formula for the 5 following compounds potassium bromide iron III sulfate copper II chloride tetraphosphorus heptanitride ammonium carbonate?
potassium bromide - KBr iron (III) sulfate - Fe[subscript 2](SO[subscript 4])[subscript 3] copper (II) chloride - CuCl[subscript 2] tetraphosphorous heptanitride - P[subscript 4]N[subscript 7] ammonium carbonate - (NH[subscript 4])CO[subscript 3]
What does the subscript g on H2Og signify?
the subscript g after H2O indicates that it is water vapour, a gas, which is what the subscript g stands for. If there was a subscript s after the H2O, it would mean that H2O is in a solid form as ice. If there was a subscript l it means that H2O is in the liquid form as water.
