A meteorologist uses a weather map to explain an upcoming change in weather. The map shows a blue line with triangles approaching a red line with semicircles. Based on the map, which weather prediction is most valid? (1 point) A a significant drop in temperature will occur across the area. B There is no chance of precipitation in the forecast. C Warm temperatures will replace cold temperatures. D Humidity levels will rise.

Option C: Warm temperatures will replace cold temperatures.

Explanation:

In a weather map, a warm front is depicted with a red line and red semi circles while a cold front is depicted with a blue line and blue triangles.

Now, we are told that the map shows a blue line with triangles approaching a red line with semi-circles. This means that the cold front is approaching the warm front.

Now a warm front is simply defined as the transition zone where warm air mass gradually replaces a cold air.

Thus, it means the weather map depicts the fact that warm temperature is replacing cold temperature.

Thus; Option C is correct.

a force of 500                  

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
