2. Saturn
Explanation:
The four planets farthest from the Sun are the outer planets. ... From left to right, the outer planets are Jupiter, Saturn, Uranus, and Neptune. The gas giants are made up primarily of hydrogen and helium, the same elements that make up most of the Sun.
Answer:
Sorry I can't see which molecules you are talking about
Answer:
You can make 149.1g of KCl
Explanation:
1 mole of potassium chloride, KCl, contains 1 mole of potassium, K. That means, with 2.000 moles of K we can make 2.000 moles of KCl. To solve this question we must convert these moles of KCl to mass in grams using its molar mass (Molar mass KCl = 74.5513g/mol):
<em>Mass KCl:</em>
2.000 moles KCl * (74.5513g / mol) =
<h3>You can make 149.1g of KCl </h3>
Answer:
Ionic
Explanation:
In this particular kind of question, we need to understand that the higher the electronegativity value, the more the potential of having an ionic bond formed between the two elements.
Thus, to establish the fact that there should be an ionic bond formation between two elements, we need to know the difference between their electronegativity values. As seen in this question, we can ascertain that the electronegativity difference is quite high. Hence due to this large difference, it is expected that it is an ionic bond that will be formed. If their strengths are comparable, then we can have a covalent bond
Answer:
<u>B.</u>
Explanation:
<u>Correct:</u> b. The mass of the Carbon-14 sample is greater than the Carbon-12 sample, but the reactivity of both samples was the same .
- C-14 has two additional neutrons, so is heavier than C-12. The chemical properties will be the same, however.
