Explanation:
(1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.
Answer:
Sodium is an alkali metal so it needs to lose an electron to fill it's outer shell.
That is an ion. When an element loses or gains an electron but in this case, sodium needs to lose an electron.
The answer is :
each synthesis reaction Include a hypothesis relating to whether PCl3 or PCl5 will be produced, information about the initial masses you would use, and possible problems that might arise.
Explain Hypothesis.
- hypothesis are ones which give probabilities to potential observations.
- The contrast here is with complex hypothesis, also known as models, which are sets of simple hypothesis such that knowing that some member of the set is true (but not which) is insufficient to specify probabilities of data points.
- Example :- If plants are watered with a 10% detergent solution, their growth will be negatively affected.
