Can a element be a metal and a non metal

Chemistry
1 answer:
Dmitry [639]4 years ago
6 0

Answer:

no

Explanation:

because in the periodic table there is a section for metals and a section for non metals. 'non' implies that it is not a metal and having an element be both metal and non metal would be contradictory.

maw [93]

Answer:

22.73s

Explanation:

The reaction is a second order reaction, we know this by observing the unit of the slope.

rate constant = k = 0.056 M-1s-1

the initial concentration of BrO- [A]o = 0.80 M

time = ?

Final concentration [A]t= one-half of 0.80 M = 0.40M

1 / [A]t = kt + 1 / [A]o

1 / 0.40 = 0.056 * t + 1 / 0.80

t = (2.5 - 1.25) / 0.056

t = 22.73s
