It can only move through both air In spacecraft
Explanation:
B: The plants take the CO₂ and turns it into O (oxygen)
F: The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. respiration takes place in the mitochondria of the cell in the presence of oxygen
E: Most organisms become fossils when they're changed through various other means. This process which is called carbonization, or distillation yields a detailed carbon impression of the dead organism in sedimentary rock
Answer:
14.9 g is the ideal yield of Cu(NO₃)₂
Explanation:
Reactants for the reaction: Cu and AgNO₃
Products: Copper nitrate and Ag
The balanced reaction is: Cu(s) + 2AgNO₃(aq) → 2Ag (s) + Cu(NO₃)₂
As the silver nitrate is in excess, the Cu will be the limiting reagent.
We convert the mass to moles → 5.05 g . 1 mol/ 63.55 g = 0.0794 moles
Ratio is 1:1, so 0.0794 moles will produce 0.0794 moles of Cupper(II) nitrate. We convert the moles to mass, and that value will be the theoretical yield.
0.0794 mol . 187.55 g /1 mol = of Cu(NO₃)₂
Answer:
I would say B all of these
Al S
1) <u> 35.94 </u> =1.33111 <u> 64.06 </u> = 2.001875
27 32
2) = <u> 1.33111 </u> = <u> 2.001875 </u>
1.33111 1.33111
3) = ( 1 ) × 2 = ( 1.5 ) ×2
4) = 2 = 3
Empirical Formula = Al2S3
1) Divide the percentage given in question by the Relative Atomic Mass (RAM)
of the given elements.
2) When you find the answers of the first part of question, divide these once again but this time, by the lowest number you found in part 1.
3) and 4) Write down the values. If you get a decimal which is in between 0.3-0.7 (including the 0.3 and 0.7), you cannot make it a whole number by rounding of. Therefore, multiply the decimal with a whole number until you get a whole number as your answer. In this question, when you multiply 1.5 by 2, the answer is 3 which is a whole number. Multiply the other whole number by the same number as that you multiplied for 1.5. And use these numbers in part 4 to make the empirical formula which is Aluminium Sulfide (Al2S3)
Hope this helps you :)))
