Answer:
Average velocity = 0.3 m/s.
Explanation:
Given data:
Total distance from house to store = 500 m
Distance he traveled from store and stop before reached to house = 200 m
Total time taken = 910 sec
Average velocity = ?
Solution:
Formula:
Average velocity = displacement / time
Displacement = distance from start - end point
Displacement = 500 m - 200 m = 300 m
Average velocity = 300 m/ 910 s
Average velocity = 0.33 m/s
Average velocity = 0.3 m/s.
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.

All isotopes have the same number of protons and the same number of electrons. Because the electron structure is the same isotopes have the same chemical properties.
