Answer:
Type: M
Name: Dixytrogen Pentasulfide
Molar Mass:
X*2 = Number * 2 = Number
S*5=32.066*5=160.33
Number + 160.33 = Molar Mass (g/mol).
(The mass for Xytrogen is not present).
Explanation:
Assuming Xytrogen is a non-metal and bonding it with sulfur, another non-metal would make it covalent or molecular.
The name is from the amount of Xs (being two [Di]) and the amount of Ss (being five [Penta]).
The molar mass is explained above. You need to multiply the mass of each element by the number of elements present in the compound. The mass for Xytrogen is not present (as it is a made up element) so I left instructions how to do it once given the mass instruction.
Hope this helps.
Answer:
Here is your answer: Tin,
Explanation:
Which of the following elements probably has the most properties in common with lead (Pb)? Tin (Sn).
Answer:
Rate = 0.001615 Ms-1
Explanation:
2 NO2 + F2 --> 2 NO2F
The reaction is first order with respect to NO2 and also first order with respect to F2.
The rate law is given as;
Rate = k [NO2] [ F2]
k = 1.58E-4 M-1s-1
[NO2] = 2.84 M
[F2] = 3.60 M
Rate = ?
Inserting the values into the equation, we have;
Rate = 1.58E-4 * 2.84 * 3.60
Rate = 0.001615 Ms-1
We have to know which do not violet octet rule.
The central atom in SF₄ does not violate the octet rule. the central atom in CF₄ does not violate the octet rule.
As per octet rule, atoms can combine either by transfer of valence electrons from one atom to another or by sharing of valence electrons in order to have an octet in their valence shell.
The central atom S of SF₄ contains 8 electrons in the valence shell. Also, C atom of CF₄ contains 8 electrons in the valence shell.
ICl₄⁻ contains 9 electrons in the outermost shell.
