Distillation is a widely used method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points , into the gas phase .
D. More collisions occur and the time required for the reaction decreases
This happens because according to collision theory, when energy (in this case, thermal energy) is applied to particles, they move/vibrate more quickly.
Answer:5
Explanation:In order to be able to say how many sig figs are used for the measurement 811.40 g, you need to know that
<span><span>
non-zero digits are always significant</span><span>
a trailing zero that follows a decimal point and a non-zero digit is always significant</span></span>
In your case, the measurement
<span>811.40</span>
has four non-zero digits and one significant trailing zero.
<span><span><span>8,1,1,4</span>→</span> non-zero digits<span><span>8,1,1,</span>0→</span> significant trailing zero</span>
Therefore, you can say that this measurement has <span>five significant figures</span>
<span>811.40→</span> <span>five significant figures</span>
C would be the correct answer
