Answer:
≈ 0.10M
Explanation:
[A]o = 0.27M
Rate constant, k = 0.75 s−1
[A] = ?
time, t = 1.3
Integrated formular for a first order reaction is given as;
ln[A] = ln[A]o − kt
ln[A] = ln(0.27) - 0.75(1.3)
ln[A] = -1.309 - 0.975
ln[A] = -2.284
[A] = 0.1019M ≈ 0.10M
Answer:
D. Malleability
Explanation:
Gold is made up of the element Au and it is a metal.
Pyrite is iron sulfide and it is a non-metal.
- They have very similar appearance to such an extent that pyrite is widely called the fool's gold.
- To distinguish between the two, we simply explore their metallic properties.
- Gold is malleable. Pyrite is not. It will crumble under pressure.
