Which of the following is the most reliable prediction about the future of some nonrenewable energy resources?
A
Fossil Fuel supplies will decrease & the cost of fossil fuels will increase.
B. Enough new coal & oil will form to meet our needs in the future
C. Coal will be in short supply, but oilwill still be widely available for our use.
D. In the near future, people will no longer need to conserve fossil fuels

the dependant variable is spilled water

the independent is the heat

if you're asking what comes out, it's steam.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
