Which of the following statement is not correct? (2023)

What is the statement is not true?

A false statement is a statement that is not true. Although the word fallacy is sometimes used as a synonym for false statement, that is not how the word is used in philosophy, mathematics, logic and most formal contexts. A false statement need not be a lie.

Hence, option (C) is not correct., the atoms lose their electrons more easily is not a correct statement about the trends when going from left to right across the periods of the Periodic Table.

Explanation: The order of a reaction is not equal to the sum of the stoichiometric coefficients of reactants in the balanced chemical equation for a reaction.

As we move from left to right across the periods of the periodic table, the non-metallic character increases. Therefore tendency to lose an electron decreases. So, option 3 contains an incorrect statement. (d) Metallic character increases down the group and decreases across a period.

A true-false statement is any sentence that is either true or false but not both. A negation of a statement has the opposite meaning of a truth value. A negations is written as ~p.

Here are a few examples: 'I think that this film is the best one in the series'. 'Mount Everest is the tallest mountain in the world'. We can see here that the first sentence is a statement of opinion, while the second is a statement of a fact.

On moving from left to right across the period, the nonmetallic character increases. Hence the tendency to lose electrons decreases. So the given statement in option C is incorrect.

The lanthanides and actinides possess more complicated chemistry that does not generally follow any trends.

It refers to an increase in structure for better and enhanced functioning of organs. Hence, from the above points, it becomes clear that the statement 'Growth continues throughout life' is not correct.

The different types of chemical reactions are combination, decomposition, single displacement, double displacement, reduction and oxidation reactions (redox reactions). Corrosion is not a type of chemical reaction.

Which of the following statement is not correct but about order of reaction?

The order of a reaction is experimentally determined. order is the sum of the powers to which the concentration of reactants is raised in a rate law expression. Therefore, options A, B, and D have correct statements. And option C is an incorrect statement.

Melting of ice is not an example of chemical change as the chemical composition of water remains the same even after melting.

Mendeleev could not explain the position of isotopes in his periodic table and hence, their postions were uncertain.

Correct answer: (c) valence electrons. Explanation: The number of valence electrons does not increase while moving down the group in the periodic table.

Hence, option (B) is incorrect., Isotopes are positioned in an adjacent group (s) in the Periodic Table, which is erroneous regarding the Modern Periodic Table, and the elements in the Modern Periodic Table are organized based on their increasing atomic masses and decreasing atomic numbers, respectively.

In math, a certain statement is true if it's a correct statement, while it's considered false if it is incorrect. And if the truth of the statement depends on an unknown value, then the statement is open.

What are True or False questions? True or false questions are a type where the answer is either 'true' or 'false. ' The question typically consists of a statement, and the test-taker needs to select a 'true' or 'false' response. There are other variations such as 'yes or no,' 'agree or disagree,' 'this or that.

For a sentence to be true, every part must be "true".

A sentence may be mostly true because it contains correct information but it is ultimately false if it contains any incorrect information.

Statements are sentences that express a fact, idea or opinion. Statements do not ask questions, make requests or give commands. They are also not exclamations.

What are the types of statement?

A statement is true if what it asserts is the case, and it is false if what it asserts is not the case. For instance, the statement “The trains are always late” is only true if what it describes is the case, i.e., if it is actually the case that the trains are always late.

Contradiction: A statement form which is always false.

A conditional statement is false if hypothesis is true and the conclusion is false. The example above would be false if it said "if you get good grades then you will not get into a good college".

Basicly there is no boolean value. The number 0 is considered to be false and all other numbers are considered to be true....

A true statement is one that is correct, either in all cases or at least in the sample case. For example, the number three is always equal to three. It's also equal to six divided by two. Any variable, like x, is always equal to itself.

The statement is only false when both parts of the statement are false. In other words, the statement is only false if “it will rain” is false and “it will snow” is also false. When one or both parts of an “or” statement are true then the whole statement is true.

As there are only two possible answers, it is key that you read each question thoroughly. When answering a True or False question, you must determine if everything the statement says is 100% true. If the entire statement is not 100% true, it is incorrect and must be marked False.

A proposition is a statement that is either true or false.

What are the 3 conditional statements?

Conditional Statements : if, else, switch.

(ii) ∅ ⊆ {∅}. Answer. True; every set has the empty set as a subset.

Zero is used to represent false, and One is used to represent true. For interpretation, Zero is interpreted as false and anything non-zero is interpreted as true. To make life easier, C Programmers typically define the terms "true" and "false" to have values 1 and 0 respectively.

If zero is the empty set, then the statement reads ∅∈{∅}, which is true.
