B
Explanation:
it's on the internet and I just know because I did this before too
Answer:
it would become darker. there would be a higher level of water pressure. and there would be less animals, or different alimals.
<u>Answer:</u> The given quantity is a type of length and is measured i the units of meters.
<u>Explanation:</u>
For the given quantity which is 4.8 meters, the unit is meters ans it the unit used to measure the length of an object.
For example: The height of the building is 150 meters. This statement means that the length of the building from the ground is 150 and it is measured in the units of meters.
Hence, the given quantity is a type of length and is measured i the units of meters.
Answer & Explenation:
2H2 + O2 -> 2H20 is the balanced equation for the reaction of Hydrogen with Oxygen to form water so
If you have 32g of O2 this is a simple Dimensional analysis problem
32g O2 x 36.03056g H20/31.9988g O2 this way the O2 cancels out and you are left with just the H2O so your raw answer would be 36.0319112, then if your instructor requires a significant figure answer that would be to 2 significant figures the information you were given 32g O2, so as above 36g or Water are produced. Just a different way to view and solve the problem with the balanced equation so you can see the way everything relates to everything else. the molar masses of O2 and H2O are simply found my adding up 2 Oxygens 15.9994g x2 = 31.9988g and H2O = 2(1.00794) + 15.9994 = 18.01258 but you then have to multiply that by 2 because the reaction states you get 2 mols in the reaction so that is where I came up with the 36.03056g for the solution. Hope this helps. Dimensional Analysis is and can be one of the best ways to solve these problems, because not always are you going to be dealing with 1:2 ratios.
