Answer:
Rate of reaction = 2.0 M/s
Explanation:
2H2O2(g) --> 2H2O(g) + O2(g)
Rate of formation of H2O = 2.0 M/s
Rate of reaction can be measured using multiple techiques and parameters like volume, pressure etc.
Among these techniques is the measurement of appearance of products.
This means we have;
Rate of reaction = Rate of appearance of product
Hence;
Rate of reaction = 2.0 M/s
Answer:
Reflection takes place from the polished smooth surfaces
Explanation:
A vacuum does not refer to an opaque body. An opaque body does not allow light to pass through it while a vacuum is simply empty space without air.
A smooth polished surface often acts as a mirror, it is a good reflector of light.
The moon is a non luminous body in the sky. It merely reflects the light from the sun.
A Pinhole camera can not take pictures of moving objects because it only focuses on any image placed before it.
Shadows are not inverted, the always appear upright.
If the heat is absorbed, then the temperature will increase as well.
