The answer is C) catalyst speed up reactions and activation energy
It would have 98 neutrons.
Explanation:
The formula for finding neutrons when given the atomic number and the mass is to do (mass - atomic number.) In this case, the mass is 156 and the atomic number is 58. So we subtract 156 - 58, which gives us 98. Therefore, it would have 98 neutrons.
Answer:
these gases accumulate in the atmosphere and create the heat-reflective layer that keeps the Earth at a livable temperature. These gases form the insulation that keeps the planet warm enough to support life
If you remove thermal heat from the reaction the reaction will slow down. meaning that there will be fewer collisions occurring between the particles.

Answer:
The correct answer is - so that other scientists can replicate the experiment and make sure the results are correct or to check accuracy.
Explanation:
The data and procudres are required to be recorded or noted correctly so the experiment and research can be replicate and tested for the accuracy of the experiment by other scientist and researcher.
Mandy also need to note procedure, data, variables and other data correctly for the testing the accuracy and replication of the experiment. The replication is essential to check if every thing is correct and result are error free.
