Answer is: C. bias or judgment.

Objective observations are accurate if there are not influenced by the observer's judgenebt, feelings, opinions or biases.

Observation is the active purchase of information from a primary source.

There are two types of data collecting: quantitative and qualitative observations.

1) Quantitative observations are made with instruments (in this example balance).

This data are measurable and can be expresed with numbers.

2) Qualitative observations are information about the quality of substances.

In qualitative observation, informations are collected using senses (sight, hearing, taste, smell and touch).

Qualitative observations are not measurable and cannot be recorded in terms of numbers.

Chemical reactions can be detected by precipitation of a _____ from a solution.

RideAnS [48]

Answer: solid

Explanation: Chemical reactions are those which involve rearrangement of atoms.

Chemical changes are accompanied by following changes:

1) Absorption or release of heat

2) Change in color

3) Formation of gas bubbles

4) Formation of a solid product called as precipitate

Example of formation of precipitate or solid in chemical reaction: $2AgNO_3(aq)+BaCl_2(aq)\rightarrow 2AgCl(s)+Ba(NO_3)_2(aq)$

The cis and trans geometric isomers of a compound have different chemical and physical properties. Draw the structure of the geo

frutty [35]

<u>Answer:</u> The structure of the geometrical isomers are attached below.

<u>Explanation:</u>

Cis- and Trans- isomers are the geometrical isomers which have same chemical formula but different structural formula

According to CIP rule, the groups on the doubly bonded carbon atoms are given priorities based on the the atomic masses of first connected atom.

If the highest priority groups are on the same side, it is known as cis-form and if the highest priority groups are on opposite side, it is known as trans-form.

We are given a chemical compound, which is 2-pentene.

In this the highest priority groups are methyl and ethyl groups.

When the groups are on the same side, it forms cis-form and when the groups are on the opposite side, it forms trans-form

The structure of the geometrical isomers are attached below.

In order for a process to be spontaneous, Multiple Choice the entropy of the surroundings must increase. the entropy of the surr

Crazy boy [7]

Answer:

The correct answer is entropy change of the surrounding plus the entropy change of the system must be positive.

Explanation:

The term entropy is a state function.Entropy can be defined as the disorder or randomness of the molecules in a system.

A spontaneous reaction is a type of reaction which deals with the release of free energy.The change of free energy in case of spontaneous reaction is always negative.

According to the second law of thermodynamics a spontaneous reaction will occur in a system if the total entropy of both system and surrounding increases during the reaction.
