How would one express 356,000,000 km in scientific notation?

3.56 times 10^8 i believe is your answer

3.56 × 10^8

1. Move the decimal to the left until it gets to a number below ten

2. Then count the number of times you moved it over

3. Multiply the first number you got (3.56) by 10 to the power of how ever many times you moved the deecjaml over.

It will look like this: 3.56 × 10^8

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
