It's Oxygen.
electronegativity is an arbitrary measure of how much will an electron get attracted to an atom of an element
as we know, oxygen is the best at accepting electrons from this list, so the answer is oxygen
Answer:
memory cells
Explanation:
The unscrambled words are white blood cells, memory cells, and antibodies. Memory cells is the correct answer, so that's what you'd write.
Since we are already given the balanced equation:
→ 
We can derive the molar ratios as: 1:2:1:1
That being said, we are given 0.172 moles of bromine (
), so it has a ratio of 1:1 with sodium bromide (
).
So we can take from that ratio, that when 0.172 moles of bromine are used, we are, in turn, going to get 0.172 moles of sodium bromide produced.
Seafloor spreading is the answer to your question.
Here are three everyday situations which it would be useful to identify unknown substances:
1. When you have two clear substances with no labels yet you are not sure which substance is water and which one is not and not knowing what this unknown chemical might do.
2. A stain on your clothes
3. When you are not feeling well and your sense of taste is not functioning well.
The ways that these can be identified is first, start by the appearance, for example the state, color, texture, etc. And secondly, use your sense of smell. This sense is also helpful in identifying whether the substance is something strong or not.
