1 mol 2 mol
84g of N2(g) = 84/28 = 3 mol of N2(g)
From the above reaction 1 mol of N2(g) gives 2 mol 0f NH3(g). So 3 mol of N2(g) should give 6 mol or (6x17) 102 g of NH3(g). But we are getting only 85.0 g of NH3.
Hence %yield of NH3 = 100x85.0/102 = 83.3%
Answer D. is correct.
2. 2HgO (s) --------------------- 2Hg (l) + O2 (g)
2 mol 2 mol 1 mol
4 mol 4 mol 2 mol
As only 1.5 mol of O2 is obtained, so % yield = 1.5x100/2 = 75.0%
Moreover 603 g of Hg = 603/200.59 = 3.00 molof Hg. Considering this also
% yield = 3x100/4 = 75%
thermal energy to heat energy i think
Explanation:
because option one , two , four are not the energy which is related to photosynthesis
Answer:
A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of.
HOPE THIS HELPED!!!!!!!!!!!!! XDDDDDDDDDDD
Answer:
A) DNA passed from the heat-killed strain to the living strain.
Explanation:
This is an analogue to the Griffith´s experiment, reported in 1928. He tested Streptococcus pneumoniae transformation, which changed from non virulent to virulent. That was the first experimental evidence of bacterial transformation, this is, the transference of genetic material from one bacteria to another.
