The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
Salient rules means those rules likely to have a significant effect.
Use the rules of significant figures to answer the following : 22.674 * 15.05. Answer: 341.2
rules for calculating S.F. are: 1,all non zero digits r significant 2,
all non zero digits are significant .2.zeroes betweenother significant.

rules to follow in determining the number of sigificant * zero's are not significant at the end of the whole number which does not have a decimal point * EXAMPLE: 3400 ( 2 sf's) 2000 (2sf's)*
Significant figures are the digits in a number that contribute to its precision. The rules include: all non-zero digits are significant; zeros between significant digits are significant; leading zeros are not significant; trailing zeros in a decimal number are significant; and in whole numbers without a decimal point, trailing zeros are not considered significant. When performing calculations, the result should be reported with the same number of significant figures as the measurement with the least significant figures involved in the calculation.
true
If they did not use rules all their calculations would simply lead to random digits!
No, exact quantities are not considered when applying significant figure rules. Exact quantities are known with complete certainty and do not impact the uncertainty associated with measured quantities. Significant figures are only counted based on measured values.
It shows that Jack rules by fear and violence.
