Is H2 an element or compound?
H2 is an element as it does not include any other elements from the Periodic Table.
Which of the following elements are in this chemical reaction Zn (s) HCl (g) ZnCl2 (s) H2?
Zn (zinc) is an element. H (hydrogen) is an element. Cl (chlorine) is an element. H2 (hydrogen gas) is NOT an element.
What are the di-atomic elements?
The seven diatomic elements are hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2). These elements naturally exist as molecules consisting of two atoms bonded together.
What is the Net Charge for H2?
Zero. All elements (as well as elemental molecules such as O2, H2, Cl2, etc) have a net charge of 0.
What does h2 stand for in the periodic table?
H stands for the element hydrogen. H2 is hydrogen molecule and is not listed on the periodic table.
Is H2 an element or compound?
H2 is an element as it does not include any other elements from the Periodic Table.
What is the chemical formula for oxygen and hydrogen?
Chemical Name = Oxygen Chemical Symbol = O There is no chemical formula for elements.
What is the formula for an ionic compound that contains the elements magnesium and sulfur?
the formula for an ionic compound that contains the elements magnesium and sulfur.Mg + H2 SO4 -> Mg SO4 + H2. .
Which of the following elements are in this chemical reaction Zn (s) HCl (g) ZnCl2 (s) H2?
Zn (zinc) is an element. H (hydrogen) is an element. Cl (chlorine) is an element. H2 (hydrogen gas) is NOT an element.
What elements are oxidized and what are element are reduced N2 H2--NH3?
In the reaction N2 + 3H2 → 2NH3, nitrogen (N2) is reduced because it gains hydrogen atoms, and hydrogen (H2) is oxidized because it loses electrons.
What are the di-atomic elements?
The seven diatomic elements are hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2). These elements naturally exist as molecules consisting of two atoms bonded together.
What is the Net Charge for H2?
Zero. All elements (as well as elemental molecules such as O2, H2, Cl2, etc) have a net charge of 0.
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 elements are in this unbalanced chemical reaction Li plus H2O LiOH plus H2?
lithium, hydrogen, oxygen
How does the reactivity of the elements in group 2 change on descending the group?
As you go down the Group 2 (alkaline earth elements) elements they become more and more reactive. i.e. H2O+Ca=Ca(OH)2+H2 there is more hydrogen (g) created and at a faster pace than H2O+Mg=Mg(OH)2+H2.
What does h2 stand for in the periodic table?
H stands for the element hydrogen. H2 is hydrogen molecule and is not listed on the periodic table.
What are elements found in the nature as a diatomic molecule?
Some elements found as diatomic molecules in nature are hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), and chlorine (Cl2). These elements exist as diatomic molecules because they are more stable when paired together due to their electron configurations.
