Answer:
Veja, por exemplo, que os elementos mais eletronegativos são os que estão no canto superior direito da tabela, isto é, o flúor (4,0) e o oxigênio (3,5), e os menos eletronegativos são os que estão no canto inferior esquerdo, que são o frâncio (0,8) e o césio (0,8).
Explanation:
Answers are:
Catabolism:
- g<span>enerally exergonic (spontaneous): In this reactions energy is released.
- </span><span>convert NAD+ to NADH. Electrons and protons released in reactions are attached to NAD+.
- </span><span>generation of ATP. ATP is synthesis from ADP.
- </span><span>convert large compounds to smaller compounds. Foe example starch to monosaccaharides.
Anabolism:
</span><span>- convert NADPH to NADP+. Protons and electrons are used to make chemical bonds.
</span>- <span>convert small compounds to larger compounds.</span>
Answer:
Hi,
The assembling of proteins starts with the attachment of m RNA to the ribosomes in the cytoplasm. Each of the ribosome read the code in the m RNA from “start” to “ stop” choosing the specific amino acid building block and removing the unwanted growing protein. The ribosome performs this process in 0.02 seconds and with this rate it is possible for the cell to perform assembling of small protein such as insulin.
Best wishes!
53.14 grams of Zn
will be produced from 26.0 g of Zn and 42.0 g of HCl.
Explanation:
Balanced chemical reaction:
Zn + 2 HCl ⇒ Zn + 
data given:
mass of Zn = 26 grams
mass of HCl = 42 grams
mass of Zn = ?
here in the reaction Zn is the limiting reagent so mass of
Zn formed will be determined by it.
atomic mass of zinc =65.38 grams/mole
number of moles = 
putting the values in the above equation:
number of moles of zinc = 
number of moles of zinc = 0.39 moles
From the balanced reaction it is seen that
1 mole of Zn produced 1 mole of Zn
0.39 moles will produce x moles of Zn
0.39 moles of Zn (atomic mass of Zn = 65.38 grams/mole)
mass = atomic mass x number of moles
= 0.39 x 136.28
= 53.14 grams
53.14 grams of Zn is formed
