Which does a reference point provide? select two options
d a position from which to measure future distance
a set of standard units for measuring displacement
da standard method for evaluating variables
da method for determining the speed of an object
a way to detect an object's motion

The reference points provide as follows:

Option A, and E

Explanation:

The reference points are the standard points or we can say the origin point of the graph. Based on the reference points, the measurements in the graph in x-axis and y-axis can be done. Similarly, reference points are those which helps in measuring displacement as the starting point is always considered as the reference point.

Even in most of the experiments, standard or reference points are kept to maintain the accuracy and precision of the obtained results. So it can also be a standard point for finding a way to detect an object’s motion and speed as well as position to measure displacements.

Options A and E, like the person above said.

Explanation:

Used their answer, and got a 100% on my quiz! So yes, this is the right answer! Right on edg2020!

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
