Answer:
The oxygen atom has a slightly negative charge.
Explanation:
3.5 - 2.5 = 1
For ionic bond electronegativity should be more than 1.6.
So, O and C do not have whole charge. Electronegativity of O more than C, so electrons slightly moved to the oxygen side.
To measure a vector is to characterize both its direction (in one form or another) and a value (usually, a number). For example, velocity of a car moving on the road is a vector and, to measure it, we have to specify its direction (e.g. North or at angle 20 degrees from the North) and value (e.g. 40 m/sec).
It is important to use the same balance throughout the entire experiment since the calibration of each balance is not the same and changing balances could result in a systematic error.
There are three types of errors that could affect the results of the experiment. The effect of random or indeterminate errors is hard to predict, its effect on the results of the experiment could be different every time. The second type of error is the systematic or determinate error, which causes a shift in results in a specific direction. The last type of error in an experiment is human error.
The type of error that could be related to the use of different balances throughout the experiment is the systematic error. Instruments could be a source of error especially if they are poorly calibrated. Also, analytical balances are calibrated differently which may result in inaccuracy in the weighing of chemicals.

They will not have to pay any cost because the accident was not Dave’s fault, Eli will be covered by Dave’s family car insurance policy, they will be protected by the other driver’s insurance. (B,C,D)
