Answer:224
Explanation:
We should answer it with Stoichiometry
We say: 20 g H2× (1 mol/ 2g)× ( 22.4 lit/ 1 mol) = 224
Means: we have 20 grams and every 2g H2, equals to 1 mol of it and every 1 mol of H2, equals to 22.4 lit( because of STP)
hope you got this:)
Answer: The structure of
1-Butyne is shown below and it contains;
Nine Sigma Bonds Two Pi Bonds
Explanation:
In given structure the sigma bonds are highlighted with blue colour and pi bonds are highlighted by Black colour and indicated by red arrows.
Remember the very first covalent bond between two atoms is always the sigma bond. After formation of sigma bond if further p orbitals with unpaired electrons are available they will form pi bond, or two pi bonds as in given scenario.
Answer:
Density is a measure of mass per unit of volume. Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume.
I hope it helps.
Have a great day.
Answer:
Period and groups are different because
PERIODS are the number of shells
I.e in lame man words the no of circles when drawn an element
GROUPS : these are the number of electrons in the outermost shell
Groups determine the valency*
These minutes are further divided into sixty parts called seconds. The words minute and second used in this context have no immediate connection to how those words are usually used as amounts of time. In a full circle there are 360 degrees. Each degree is split up into 60 parts, each part being 1/60 of a degree.
No then contact me about that
