Converting a liquid to a gas is evaporation.
There are three specific types of stress.
Compression occurs when pressure pushes in on an object from opposite sides this happens slowly.
Tension occurs when pressure pulls on opposite sides of an object, causing it to stretch this happens quickly.
shear occurs when two objects try to slide past each other in opposite directions this happens not to fast but not to slow.
Be and B: Be is 1s2 2s2 and B is 1s2 2s2 2p1
Be has full 2 orbitals and so does B but B only has 1 electron in p so it is really unstable and easy to react. So there is a dip in ionization energies. The other questions are similar to this so if you need, feel free to ask me
B - A chemist might determine the fat content in a candy bar.
1) Fatty acids stored in candy bars are (in fact) composed of chemical substances.
2) Choice A makes no sense. This activity belongs in the Biology field. Or if you're an animal activist, you might be interested in undertaking this as a hobby.
3) Choice C is absurd because either you're a Physicist who enjoys an occupation such as this, or you're just plain crazy.
4) Choice D is preposterous because either you're a Meteorologist, or a Geoscientist. Both of which have nothing to do with chemistry.
Answer:
A) 12 mol H2O.
Explanation:
Hello,
In this case, for the given reaction:
We notice that oxygen is in a 7:6 molar relationship with water, for that reason, the resulting moles of water turn out:
Thus, the answer is A) 12 mol H2O.
Best regards.
