A double bond consists of 1 sigma bond and 1 pi bond, and a single bond consists of 1 sigma bond. Between a sigma bond and a pi bond, a sigma bond is stronger due to it's shorter bond length, thus, a C=C bond is not twice as strong as a C-C bond.
Double bonds are shorter than single bonds, and also stronger than single bonds (though less than twice as strong).
yes
It says that in your molecule, the element in front of the little 2 occur twice. So in CO2, a carbon-atom occurs once, and the oxygen-atom occurs twice.
Carbon oxygen and chlorine the 2 stands for that but twice
Carbon has four bonding sites, so four hydrogen atoms will bond with a single carbon atom to create CH4--which is methane. Six will bond with a pair of carbon atoms to make ethane, eight will bond with three to make propane...and that keeps on going until the carbon chain is long enough to loop around upon itself. If it does that, each carbon atom will have two open bonds so in ring-form hydrocarbons you have twice as many hydrogens as you do carbons. One exotic hydrocarbon is heptane, which is used as a solvent for rubber cement among other things...it has seven carbons, but it's a straight-line molecule (meaning there is a bonding site at each end of the chain in addition to the two on each carbon atom) so the formula is C7H16.
well a single turn is where you turn once in a stunt and a double turn is where you turn twice
Twice the size of a single garage.
Double bonds are shorter than single bonds, and also stronger than single bonds (though less than twice as strong).
Yes. Double every single ingredient. You will get twice as many.
when it is possible to spend a single digital token twice
A paper will be twice as long when double-spaced compared to single-spaced. For example, a one-page single-spaced paper would be around two pages when double-spaced.
In double circulatory system the blood travels trough the heart twice in it's way around the body, while in the single it only goes through the heart once.
Double-clicking means to click a mouse button twice in succession. Usually, it is the left button that is double-clicked. A single click is often used to highlight an icon, while a double-click opens it.
because the nucleus is surrounded by a nuclear envelope - a double membrane. since it has 2 membranes it is twice as thick as a single plasma membrane
Two strikes in a row. In others words, knocking all 10 pins in a single shot, twice in a row.
5 double spaced pages is equivalent to 10 single spaced pages. Each single spaced page will have twice the content of a double spaced page, so it takes two single spaced pages to match the content of one double spaced page.
twice of CO2 gives on heating twice of CO & O2
