‘Inference’ is a noun and its meaning is the act or process of reaching a conclusion about something from known facts or evidence. An ‘inference’ can be a verbal statement, but more commonly it refers to a thought process. For example: It seems like a reasonable inference that it is cold outside, because everyone I see is wearing a coat. An inference is usually made about something with a degree of certainty, based on facts like statistics, calculations, observations or generalizations. ‘Infer’ is the verb form of ‘inference’, having the same meaning, to form an opinion or reach a conclusion based on known facts. For example: We can infer that it is cold outside based on what we see people wearing. Synonyms include words like ‘surmise’, ‘deduce’, ‘reason’ and ‘conclude’.
‘Prediction’ is also a noun. It means a statement about what will or might happen in the future. A ‘prediction’ generally is a verbal statement, but it can mean just a mental thought. For example: I made a prediction that it will snow tomorrow. There is also a commonly used verb form of ‘prediction’, ‘predict’. ‘To predict’ means to say that something might or definitely will happen in the future. For example: I predict it will snow tomorrow. While ‘prediction’ and ‘predict’ are usually based on some sort of fact, observation, experience or scientific reason, these meaning behind these words does not have definite certainty of occurring. Something that someone predicts may or may not actually happen. A good example of an everyday prediction is the weather forecast. What is forecasted, or predicted, is based on scientific evidence, but it is not a known certainty, just a <span>probability.</span>

Answer:
1) Dispersion forces: It is a type of force which is present between atoms and molecules. It is a weakest intermolecular force that occurs between atoms. It is also called induced dipole-induced dipole attraction.
2. Dipole-dipole: It is a type of attractive force which is present between the negative end of one molecule with the positive end of another molecule. This type of attractive force occurs between polar molecules.
3) Hydrogen bond: It is a type of electromagnetic force which is present between hydrogen and high electronegative atoms such as nitrogen and oxygen etc.
Answer:
This question is incomplete
Explanation:
This question is incomplete but generally it seem to test the knowledge of accuracy. Accuracy is the closeness of a measured value to the specific or actual value of the substance being measured. Hence, the smaller the entire scale that can contain all the substance being measured, the higher the possibility of accuracy to be achieved. For example, a pen of 10.4 cm in length can be better/accurately measured (length) with a 30 cm meter rule than a 1 m meter rule.
From the question, the 50 mL beaker will provide a "more accurate" measurement of the volume of the bromine than the 100 mL beaker if the 50 mL beaker can contain all the sample of bromine water provided.
Answer: 18.97 L
Explanation:
This can be solved by the Ideal Gas equation:
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas in Kelvin
Finding :
Therefore:
The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is <u>18.97</u> liters
