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
Answer:
the correct answer is Metallic bonding
Explanation:
hope this helps
have a awesome day
It is the concept of surface tension that helps the coin to float on the top of the water in the glass. The surface tension acts just opposite to the gravitational force and that is why when any metal placed in the water it will float and come on the surface. Hope this helps!
Answer:
D
Explanation:
If you add two or more thermochemical equations to give a final equation, then you also add the heats of reaction to give the final heat of reaction
A solid stays the same shape. The atoms a close together and don't move that much. A liquid can form to any shape, the atoms bounce around a little bit, but not much. A gas has no shape, the atoms are few and far between.
A.) Liquid
B.) Solid
C.) Gas
