Answer:
Solids have a set shape and can't flow since their particles can only vibrate in a specific direction. They are unable to travel from one location to another.
Explanation:
Answer:
427.5g
Explanation:
Given parameters:
Number of moles = 4.5moles
Unknown:
Mass of MgCl₂ = ?
Solution:
To solve this problem;
Mass = number of moles x molar mass
Molar mass of MgCl₂ = 24 + 2(35.5) = 95g/mol
Mass = 4.5 x 95 = 427.5g
What words are you looking for so i dont put them down
So knowing the mass of C and H, C=12g and H=1g. We can have 3 C's (3*12=36) and 3 H's (3*1=3) so 36+3 is 39. Plus C3H3 has an empirical formula of CH since C3H3 can be simplified
Explanation:
This atom is on the almost extreme right of the 2nd period of the periodic table (except for the stable element on the extreme right). This means it has the highest mass number of the unstable elements of the period. It thus attracts its electron clouds more strongly that the elements to the left of the period . This means it can gain an atom easily ( this is what is called electronegativity – tendency to attract an electron) than is can lose an electron. In addition, it only needs to acquire one electron to achieve a stable electron configuration (8) in its valence shell.
Due to these, it is hard for the atoms to lose an electron which is why it has a high ionization energy- the energy required to lose an electron.
