It can be observed and tested 100 % sure same ? i had and i got 100%
Explanation:
When looking across the periodic table from left to right, which is the first group that contains nonmetals is group 14.
The elements of group 14 are carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb). Where carbon is a non-metal, silicon (Si) and germanium (Ge) are metalloids, tin (Sn) and lead (Pb) are metals.
Answer:
Metallic bonding
Explanation:
Metallic bonding
These type of bonding is observed between the delocalized electrons and the metal cations and is a form of electrostatic bond .
The substance that show these type of bonding , i.e. ,metallic bonding are malleable in nature , because ,
These substance can be moulded to give various shapes ,
As, the layers of atoms can slide on each other and therefore shows the property of malleability.
Hence, from the given information of the question ,
The correct type of bonding is metallic bonding.
Answer:
4
Step-by-step explanation:
The reactions are:
Glycolysis: 1 glucose ⟶ 2 pyruvate
Link reaction: 2 × [1 pyruvate ⟶ 1 acetyl CoA]
Citric acid cycle: 2 × [1 AcetylCoA ⟶ 2 CO₂]
Now, add the reactions, cancelling species that occur on both sides of the reaction arrow,
1 glucose ⟶ <u>2 pyruvate
</u>
<u>2 pyruvate</u> ⟶ <u>2 acetyl CoA
</u>
<u>2 AcetylCoA </u>⟶ 4 CO₂
<em>Overall</em> : 1 glucose ⟶ 4 CO₂
For each mole of glucose, four molecules of CO₂ are released in the citric acid cycle.
The molar mass of CO2 is 28 grams per mole. If you are
given 2.1 moles of CO2 and you are required to find the grams of this compound,
simply multiply 28 grams per mole of CO2 by 2.1 moles of CO2 and you will get 58.8
grams of CO2.
