Which type of covalent bond is the molecule H2?
There are non polar covalent bonds in hydrogen molecules.
How many bonds are in alkenes when two carbon atoms are joined?
In an alkene with two carbon atoms being joined, there would be one double bond between the carbon atoms, and 4 single bonds for the 4 hydrogens, and it would be drawn as follows: H2-C=C-H2. This is ethene, and so it has a total of 5 bonds (unless you count the double bond as a sigma and a pi) then it has 6 bonds.
Why are most covalent bonds unstable?
In covalent bonds, two atoms share electrons. Since atoms are unstable when they do not have enough electrons in their valence shell, and neither have enough in their valence shell (since they are sharing the electrons), covalent bonds are usually unstable. Well this is a strange question. What is meant by unstable? Is it reactivity? Yes many compounds are unstable, but many such as H2O, H2 are very stable. H2 is reactive with oxygen- because the formation of H2O from O2 and H2 releases energy. However without external influences e.g radiation, other reactive species (like O2) , H2 is extremely stable.
Rank in order of decreasing rate if effusion ar h2s he h2 c3h8?
H2, He, H2S, Ar, C3H8
Examples of ionic and covalent bonds?
ionic: NaCl, KCl, KOH etc covalent: H2, O2, CH4 etc
How many moles of H2 bonds are broken if you react nitrogen with hydrogen according to the following reaction?
N2+3H2--> 2NH3 answer 3 moles of H2 bonds are broken
How many bonds and how many electrons in total does h2 share?
BUTSS
When two atoms are equally electronegative such as O2 or H2 they will interact to form?
nonpolar covalent bonds

What type of chemical bond occurs between atoms in molecules such as h2 ch4 nh3 h2 cch2 n2 cl2 and many large biological molecules?
covalent bonds --- sharing electrons

Is H2O-H2 plus O2 a balanced chemical equation?
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
What are some examples of covalent bond?
Single, double, and triple carbon-carbon bonds; carbon-hydrogen bonds; carbon-halogen bonds; hydrogen-hydrogen bonds; nitrogen-nitrogen bonds; single and double carbon-oxygen bonds; silicon-oxygen bonds; nitrogen-oxygen bonds; etc.
Examples of ionic and covalent bonds?
ionic: NaCl, KCl, KOH etc covalent: H2, O2, CH4 etc
Which bonds break and which new bonds form?
2H2 + O2 + 2H2O 2H-H + O=O = 2H-O-H..not shaped like this !! The bonds in the reactants break and the bonds in the products form. The bonds in the H2 and O2 break and the bonds in the water form.
