Answer:
3.02× 10²⁴ atoms
Explanation:
Given data:
Number of nitrogen atoms = ?
Number of moles of N₂O = 2.51 mol
Solution:
1 mole contain 2 mole of nitrogen atoms.
2.51 × 2 = 5.02 mol
According to Avogadro number,
1 mole = 6.022 × 10²³ atoms
5.02 mol × 6.022 × 10²³ atoms / 1 mol
30.2 × 10²³ atoms
3.02× 10²⁴ atoms
Answer:
The volume of corn syrup is 41.5 mL.
Explanation:
Mass of the corn syrup ,m= 57.3 g
Volume of the corn syrup = V
Density of the corn syrup = d = 1.38 g/mL
The volume of corn syrup is 41.5 ml.
The overall charge on this atom is zero if the lithium atom has three, protons, three neutrons, and three electrons.
<h3>What is an atom?</h3>
The smallest tiny particles of matter which can't be divided further is called atoms.
The lithium atom is always electrically neutral, ie, it has no charge. A proton has a unit positive charge while an electron has a unit negative charge, an atom has an equal number of protons and neutrons and thus it is electrically neutral.
Hence, the overall charge on this atom is zero if the lithium atom has three, protons, three neutrons, and three electrons.

Answer:
<em>Scheme attached</em>
Explanation:
<em>Trans</em> effect is involved in this synthesis. As in the reactions of planer metal complexes, trans effect dominates the stereo-chemistry of the product.
<em>Trans</em> effect
The role of the element present in trans position to the element to be substituted is called the trans effect. The nature of the ligand in trans position effects the substitution, if it has high <em>trans</em> effect it make the substitution difficult.
So when we attach NH₃ first to the ligand it make the trans substitution difficult, hence <em>cis</em> product will be formed.
As NO₂ has very low <em>trans</em> effect, so it doesn't effect the substitution and the <em>trans</em> product will be formed as usual.
