‘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:
U --> Th + He
Explanation:
Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4 and atomic number less than 2 as compared to parent atom the starting atom.
Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.
These radiations can be stopped by a piece of paper.
₉₂U²³⁸ → ₉₀Th²³⁴ + ₂He⁴
We can say that the water is the solvent, and the powder is the solute. This is also a solution altogether.
Explanation:- A solute is the thing being dissolved into the solvent. While the solvent is what when the solute is being dissolved in. Together, they make a solution.
Lets assume that 100 grams of the compound are present.
Carbon mass: 88.14 g
Hydrogen mass: 11.86 g
Moles carbon: 88.14/12 = 7.34
Moles hydrogen: 11.86/1 = 11.86
The moles of carbon are 7.34 and the moles of hydrogen are 11.86.
I’m going to assume here that you meant “plants”.
Animals rely on plants as a source of food. Herbivores way plants to survive and carnivores eat the herbivores to live.
Now plants rely on animals because their scat fertilizes the plants, helping them grow and survive longer.
