Answer:
The parts of an atom are<em><u> protons, electrons, and neutrons.</u></em>
A proton is positively charged and is located in the center or nucleus of the atom.
Electrons are negatively charged and are located in rings or orbits spinning around the nucleus.
The number of protons and electrons is always equal.
Answer:
1.62 × 10²⁴ atoms are in 52.3 g of lithium hypochlorite.
Explanation:
To find the amount of atoms that are in 52.3 g of lithium hypochlorite, we must first find the amount of moles. We do this by dividing by the molar mass of lithium hypochlorite.
52.3 g ÷ 58.4 g/mol = 0.896 mol
Next we must find the amount of formula units, we do this be multiplying by Avagadro's number.
0.896 mol × 6.02 × 10²³ = 5.39 × 10²³ f.u.
Now to get the amount of atoms we can multiply the amount of formula units by the amout of atoms in one formula unit.
5.39 × 10²³ f.u. × 3 atom/f.u. = 1.62 × 10²⁴ atoms
1.62 × 10²⁴ atoms are in 52.3 g of lithium hypochlorite.
Answer:
The two steps which results in the release of energy are;
A) Attraction of Na⁺ and Cl⁻<span> to form NaCl
C) </span><span>The addition of an electron to each Cl atom
Explanation:
As we know<em> Born Haber Cycle </em>is helpful in measuring the Lattice Energies of Crystal systems indirectly. So, the formation of NaCl crystal takes place in several steps. Among all steps, The formation of Chloride ions (Electron Affinity) and binding of Na</span>⁺ and Cl⁻ (Lattice Energy) are exothermic in nature, while remaining all steps require energy to proceed (Endothermic).
Answer:
Sally's average speed is 0.5 km/min
Explanation:
speed=distance/time
so, 5km/10min=0.5 km/min
Answer:
