False because every quadrilateral is a four sided shape
It is false because of the additional '0'.
False negatives are riskier than false positives because say for example, if there wasn't an attack and the IDS picked it (false positive), its not much of a harm but if there was an attack and the IDS doesn't detect it (false negative), then it can be disastrous. Yashniel

True. Apatite is harder than calcite on the Mohs scale, so it can scratch calcite.
False
False. A mineral can only scratch another mineral if it is harder than that mineral according to the Mohs scale of mineral hardness.
False is is called a stalagmite
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
Yes, calcite (calcium carbonate) reacts with dilute acids to evolve carbon dioxide. However, halite (sodium chloride) does not react with dilute acids to evolve carbon dioxide.
No, a mineral can only scratch materials that are softer than it. This is known as the Mohs Scale of Hardness, where a mineral with a higher rating can scratch a mineral with a lower rating.
True. The Mohs hardness scale ranks minerals from 1 (softest) to 10 (hardest), with each number representing a mineral with a certain level of hardness. For example, talc is the softest mineral with a rating of 1, while diamond is the hardest with a rating of 10.
