Answer:Precision can be defined as the. reproducibility of a measured value. Precision is how close the measured values are to each others. In contrast with accuracy, accuracy is the agreement between a measured value and an accepted value.
Explanation:
I'm pretty sure A, B, AB, or O.
Answer:
The answer is NH3 and CH3OH
Explanation:
The basic rule of a reaction is "like dissolves like" and for a homogenous mixture to form, there must be some common properties related to bonding.
1. KI and Hg
Normally mercury tends to form amalgam which is not a homogeneous solution.
2. LICL and C6H14
One is non polar and other is polar which makes the homogeneous reaction not possible.
3. C3H8 and C2H5OH
Both are miscible but will not develop homogeneous solution as propane is gas at normal temperature.
4. F2 and PF3
Flourine is highly electronegative and will repel fellow flourine making it not possible for homogeneous solution
5. NH3 and CH3OH
Both have same type of bonding and can react homogeneously.
