The answer is "They fracture." When struck with a rock hammer, minerals like quartz, obsidian, and hematite, fracture or break at random directions instead of along cleavage planes at consistent angles. This means that these minerals have no mineral cleavage and exhibit conchoidal or irregular fractures.
they are caused by winds and changes in seawater density.
Answer: Benzene is less reactive than methylbenzoate and more reactive than Nitrobenzene
Explanation:
This is because the methyl group on the benzene ring is an electron donating group leading to the activation of the ring and subsequently leading to more canonical resonance structure at the intermediate stage of the reaction enhancing the faster reactivity
However for the Nitrobenzene the nitro group is an electron withdrawing group leading to a slower activation and less resonance canonical structure at the reaction intermediate leading to a slower reaction than the reaction of benzene without the nitro group
Based on the information provided in this image shown above, the measurement to two (2) significant figures is equal to 3.50 mm.
<h3>What is measurement?</h3>
Measurement can be defined as an act or process through which the size, magnitude, dimensions, or distance traveled by a physical object or body is taken, especially for the purpose of an experiment.
<h3>What is a scale of measurement?</h3>
A scale of measurement can be defined as a classification which is used to illustrate the attributes of the values that are assigned to variables associated with a data set.
<h3>What is a
significant figure?</h3>
In Mathematics, a significant figure can be defined as the number of digits in a numerical data (value), typically a measurement, which enhances its degree of accuracy.

Explanation:
The orbital for fluorine is 1s 2s 2p. All of the boxes should be filled COMPLETELY until you can't no more. How do you know if you can't anymore? By the <u>atomic number</u> of the element. The atomic number for fluorine is 9. So, you keep adding arrows starting from the first box all the way to the last until you have reached the atomic number, in this case, 9.
