Answer: a. 410 K
b. 296 K
c. 394 K
d. -180 °C
e. 224°C
f. -3 °C
Explanation:
For °C to K : use °C + 273 = K
For K to °C : use °C = K - 273
Answer:
around 50–55 degrees.
Explanation:
I believe this would be it because chemical reactions haven't happened yet. This is the usual tempurature for tap water. :)
Answer:
We can tell by how the continents look. Scientists who propose the pangea theory have said this. You can see for yourself because all the continents look like puzzle pieces you could put together. Scientists can also tell from the species. For example, let's say a scientist found a bone of a creature at the edge of a continent, the edge of another would have the same species. They have also calculated that the continents in itself are still splitting apart, but very slowly. The reason they split up was because tectonic plate movements.
The reaction formula of this is NaCl + AgNO3 = NaNO3 + AgCl. The mole number of NaCl is 4/58.5=0.068 mol. The mole number of AgNO3 is 10/170=0.059 mol. So the NaCl is excess.
