Answer:
Explanation:
Combination reactions are the reactions in which two or more atoms/ molecules combine to give a single product.
Aluminum metal combines with iodine to given aluminium iodide.
Aluminium has a valency of 3 and iodine has valency of 1, so the formula is
The reaction is shown below as:
OD.......................
Answer:
Tara does not get the same results when she conducts the experiment
Explanation:
<em>The most likely reason Tara suggested to Victor to perform the experiment again before publication would be because she did not get the same results when she conducted the experiment.</em>
A good scientific research or experiment should have an element of reproducibility. In order words, the claim made in published scientific research should be reproducible by any other scientist that decides to replicate the research. <u>Tara repeated Victor's experiment in order to check its reproducibility and when she could not reproduce the results, she had to tell Victor to conduct the experiment again before deciding to publish it.</u>
Renewable energy source
reduces electric bills
low maintenance costs
reduced needs for fossil fuels and foreign oils
Explanation:
The number of protons in the element C^12 (Carbon) is 6, number of electrons 12 and number of Neutrons is 6, same as the number of protons it contains
C^13 has 13 electrons, 6 protons and 7 Neutrons this one's neutron number is different from proton number because it's an isotope
Na^-1 has gained an electron so the number of electrons it has = 24 and the number of protons shown as 11 which means there are 23 - 11 = 12 Neutrons
O^-2 has gained two electrons and got 18 electrons in total, 8 protons and 8 neutrons
