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 is H2 - 100 factorised?
-98
What is h2 plus 15 equals -16 h?
h2 -16h+15 = (h -1)(h -15) when factored
What is the equation for hydrogen plus hydrogen?
Hydrogen is naturally H2 so when you combine two H2 molecules, you will get 2H2. It won't be H4 as it will only exist in pairs, not fours. If you are combining H + H, you will get H2 So either: H+H → H2 Or H2 + H2 → 2H2
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 is a Lewis dot diagram of H2?
H-H
What is the molecular formula of hydrogen?
The molecular formula of hydrogen is H2. It consists of two hydrogen atoms bonded together.
What is a the structural formula for H2?
The structural formula for hydrogen gas (H2) is H-H, representing two hydrogen atoms bonded together by a single covalent bond.
What is the formula for hydrogen plus hydrogen?
The formula for hydrogen plus hydrogen is H + H, which combines to form the molecule H2.
Is H or Ca a elements that is a metal?
no they are both non-metal.
Is H a molecule?
H2 is the molecule of diatomic hydrogen.
How many elements in H2?
The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O). Here comes the key part. From the Periodic Table of Elements, one sees that one mole of hydrogen atoms weighs 1 gram while one mole of oxygen atoms weighs 16 grams.
