This is true because of the law of conservation of mass, which says matter cannot be created or destroyed, only transferred.
Here's the first one
- The ellipse becomes a straight line
- here's the second one they converge
They don't converge when the eccentricity ratio is zero, instead the diverge.
So "the foci converge is not true"
Hope this helps!!
One positive charge wherever the atom loses an electron!
Milk is an example of a solution.
Answer:
280 mL
Explanation:
Ideal gas law:
PV = nRT
Rearranging:
V / T = nR / P
At constant pressure:
V₁ / T₁ = V₂ / T₂
Substituting values:
250 / (15 + 273) = V / (45 + 273)
V = 276
Rounded to two significant figures, the volume will be 280 mL.
When using the ideal gas law, remember to always use absolute units for temperature, like Kelvin.
