Answer:
The mass of sugar used is 427.5 grams.
Explanation:
The formula of common sugar is 
.
Its molar mass of molecule is 342 grams per mole.
The number of moles of sugar used is equal to '1.25'
(NOTE : <em>You can calculate molar mass by adding the mass of all the atoms present in the atom. </em>
<em>Mass of Oxygen (O) = 16 ; Total number of Oxygen atoms present = 11</em>
<em>Mass of Hydrogen (H) =1 ; Total number of Hydrogen Atoms present = 22</em>
<em>Mass of Carbon (C) = 12 ; Total number of Carbon atoms present = 12</em>
<em>Total mass of molecule = 12 × 12 + 1 × 22 + 16 × 11 = 342</em>)
Explanation:
1) Based on the octet rule, iodine form an <u>I</u>⁻ ion.
Therefore,
Option E is correct ✔
2) The electronic configuration of the sulfide ion (S²⁻) is :
₁₆S = 1s² 2s² 2p⁶ 3s² 3p⁴ or [Ne] 3s² 3p⁴
₁₈S²⁻ = 1s² 2s² 2p⁶ 3s² 3p⁶ or [Ne] 3s² 3p⁶
Therefore,
Option E is correct ✔
3) valence shell electron of
Halogens = 7
Alkali metal = 1
Alkaline earth metal = 2
Therefore,
Option D is correct ✔
4) Group 2 element lose two electron in order to achieve Noble gas configuration.
And here Group 2 element is Sr
Therefore,
Option B is correct ✔
5) Group 13 element lose three electron in order to achieve Noble gas configuration.
And here Group 13 element is Al
Therefore,
Option B is correct ✔
6) For a given arrangements of ions, the lattice energy increases as ionic radius <u>decreases</u> and as ionic charge <u>increases</u>.
Therefore,
Option A is correct ✔
Answer:
Endoplasmic reticulum.
Explanation:
Second messengers are known as intracellular signaling molecules released from the cell in response to exposure to extracellular signaling molecules. Second messenger activate physiological changes at a cellular level, for example proliferation, migration, differentiation, survival, and apoptosis.
Calcium ions are hydrophilic, water-soluble molecules. They are present in intracellular component know as endoplasmic reticulum and quickly released when needed. They are necessary for many important functions including fertilization, muscle contractions, and neurotransmitter release.
