What else can I help you with?
In living systems molecules involved in hydrogen bonding almost always contain either oxygen or nitrogen or both. How do you explain this phenomenon?
Oxygen and nitrogen atoms have high electronegativity, making them adept at forming hydrogen bonds. They possess partially negative charges that attract the partially positive hydrogen atoms. This results in strong and stable hydrogen bonding interactions, which are crucial for maintaining the structural integrity and biological functions of living systems.
What is the property of hydrogen bond?
The main property is the attraction always occurs between cations of hydrogen (H+) and a negatively charged element. Also that the attraction is neither covalent nor ionic - there's no transference or sharing of electrons, only electrostatic attraction between a positive pole (H+) and a negative pole (Elementx-)
Do hydrogen bonds always involve hydrogen?
As far as I know: yes! They involve hydrogen bonded to an electronegative element (like oxygen). This Hydrogen in the molecule is then attracted to another electronegative element (like oxygen, nitrogen etc)
Is hydrogen written as a diatomic molecule?
yes Hydrogen by itself, is always H2
Which gas is always given off when an acid solution is electrolysed?
Hydrogen gas is always given off when an acid solution is electrolyzed.

Is a happy number times another happy number always a happy number?
Well if you mean positive then yes a positive times a positive is always a positive! Those numbers always have their calculators half full :)
What does a plus and a plus make in algebra?
A positive number added to another positive number always results in a positive sum.
When you add a positive number by a positive number is the number negative or positive?
Positive numbers always result in positive numbers when added, divided, or multiplied by another positive number.
Why should a car battery's positive terminal be connected first for charging?
Batteries vent Hydrogen gas. You should always connect the positive battery cable first to avoid a spark at the battery that could cause the Hydrogen to explode. The negative cable should never be connected to the battery negative post. It should be connected to another ground area on the engine.

When can the square of a negative number be negative?
This can never be. The square of any number will always be positive. Any positive number multiplied by another positive number will be positive, while any negative number multiplied by another negative number will be positive.

Is hydrogen positive or negative?
A hydrogen atom is neutral as it has the same number of protons and electrons. But as an ion, it can be either positive or negative.We usually talk about it in the positive sense; eg. It would donate it's outer electron and gain a positive charge; H+. However, in some compounds it can have a negative charge, H-.In a standard question though, always assume that it loses it's outer electron and is positively charged unless told otherwise in the question.
Does subtracting one negative number from another negative number give you a positive number or another negative number?
always another negative number
What elements make up an oxoacid?
It always has an oxygen atom and a hydrogen atom. There is always at least another atom depending on which chemical formula you are referring to.
