"h" typically represents enthalpy, which is a measure of the total heat content in a system. "H2" represents a molecule of hydrogen gas, which consists of two hydrogen atoms bound together. So "h h H2" could refer to the enthalpy change associated with the reaction involving hydrogen gas.

What is the formula for hydrogen plus hydrogen?
The formula for hydrogen plus hydrogen is H + H, which combines to form the molecule H2.
What is the formula for hydrogen molecule?
The chemical formula for a hydrogen molecule is H2, which represents two hydrogen atoms bonded together. This molecule is the most common form of hydrogen found in nature.
What is the conjugate base of h2?
The conjugate base of H2 (dihydrogen) is H-, which is called hydride ion. It is formed when H2 loses a proton.
Is H2 an acid?
No, H2 (diatomic hydrogen) is not an acid. Acids are substances that donate hydrogen ions (H+) in a solution, while hydrogen gas (H2) does not donate hydrogen ions in this way.
What is the chemical formula for hydrogen molecule?
The chemical formula for a hydrogen molecule is H2.
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 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 the formula for hydrogen plus hydrogen?
The formula for hydrogen plus hydrogen is H + H, which combines to form the molecule H2.
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.
How many carbons are in H2?
Zero: carbon=C Hydrogen=H H2=Hydrogen Gas
What is the formula for hydrogen molecule?
The chemical formula for a hydrogen molecule is H2, which represents two hydrogen atoms bonded together. This molecule is the most common form of hydrogen found in nature.
How would you find the area of a right angle triangle when its hypotenuse is greater than its height by 2.2 cm and greater than its base by 4.4 cm?
Let say A is the length of the height B the length of the base H the length of hypotenuse Then A=H-2.2 and B=H-4.4 Using Pythagore one gets H2=A2+B2 Then H2=(H-2.2)2+(H-4.4)2 or H2=H2 -4.4 H +4.84 +H2 -8.8H +19.36 H2=2H2 -13.2H +24.2 H2 -13.2H +24.2 = 0 H = (13.2-sqrt(77.44)) / 2 = 2.2 or H = (13.2+sqrt(77.44)) / 2 =11 The first solution is impossible because B=H-4.4 So H=11, A=8.8 and B=6.6 The area of the triangle is Area=(AxB)/2 = (8.8 x 6.6)/2 = 29.04
What is H2 in science?
the subscript 2 after the H indicates that the hydrogen molecule contains two (2) atoms of hydrogen
