Explanation:
Elements bond to each other by either (loosing / gaining) or sharing electrons with each other .
When bond is formed by loosing or gaining electron between metals and nonmetals then that type of bond is called ionic bond or electrovalent bond. Examples :-Nacl, Kcl etc..
When bond is formed between two elements that are non metals and bond form in between is due to sharing of electrons equally is called covalent bond.ex- Ccl4 , Sicl4 etc.
When bond formed between elements are shared unequally between atoms of elements then it is called co-ordinate bond. Ex:- No2, HCl etc..
Some people think about Metallic bond it's pretty simple actually it takes between same metal lattice. Definition is as follows
A metallic bonding is defined as where electrons freely move around a metal lattice (the metal atoms close united) to form a bond between the entire metallic element.ex:-Na, Mg and all other S , d and f block elements .
Last but not the least , Take case of hydrogen bonding it takes Place between H and electronegative elements like ( o , F , Cl , N ) etc examples are Hf , HCl , h2O etc.
Hope you have got the idea.
Answer:
Density of mercury is 13600 kg
The relation between moles and mass is given by the formula:
# of moles = (mass in grams) / (molar mass)
So, given the molar mass of 18.02 and 0.025 mol, you can solve the formula for the mass of water in grams:
mass of water in grams = # of moles of water * molar mass of water
mass of water in grams = 0.025 mol * 18.02 g / mol = 0.4505 g of water.
Then, she is wrong.
Answer:
Explanation:
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.
The complete combustion reaction for C16H34 would be as follows:
C16H34 + 17/2O2 ------> 16CO2 + 17H2O
We are given the amount of oxygen to be used for the reaction. This value would be the stating point for the calculations.
0.50 mol O2 ( 1 mol C16H34 / 17/2 mol O2 ) ( 22.4 L / 1 mol ) = 1.317 L = 1317 mL C16H34
