Answer:
(atoms.............) is the homogeneous mixture
Answer:
helps in photosynthesis
Explanation:
when there is the presence of light the photosynthesis is dine
The correct answer ; coal
Why?
Coal forms over millions of years, not just that, even now, our earth doesnt have resources as it did millions of years ago to form coal in the first place
other options are renewable because it can be renewed over, and over again
For this, we use equations from the colligative properties of solutions specifically boiling point elevation and freezing point depression. The equations for these are expressed as:
ΔTb = kb m
where k is a boiling point elevation constant and m is the concentration in terms of molality
ΔTf = kf m
where k is a freezing point elevation <span>constant and m is the concentration in terms of molality
</span>
We use both expression to solve for the freezing point. For this case, concentration is the same. The equation will then be:
ΔTf = kf ( ΔTb / kb )
0-Tf = 1.86 (103.7 - 100 / 0.512 )
Tf = -13.4°C
Answer:
Bring to the boil. Carefully place the can in the saucepan, ensuring there's enough water to completely cover the can at all times, topping up water frequently throughout the cooking process. Simmer, uncovered for 3 hours.
