How many grams are in 8.50 e 23 formula units of NaCl?
a)82.5 g
b)8.25 g
c)85.0 g
d)91.5 g
Answers
Answer:
a)82.5 g
Explanation:
To solve this problem we will use Avogadro's number, which states the number of formula units per mole.
8.50x10²³formula units ÷ 6.023x10²³ formula units/mol = 1.41 molThen we convert 1.41 moles of NaCl to grams, using its molar mass:
1.41 mol NaCl * 58.44 g/mol = 82.4 gThe closest answer is option a).

What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
Covalent compounds are formed by covalent bond and ionic compounds are formed by ionic bond. Covalent bond is formed by sharing of electron and ionic bond are formed by complete transfer of electron. Ionic bonds are stronger than covalent bonds. The melting and boiling points are higher in ionic compounds.

Explanation:
Hello!
In this case, since the equilibrium expression is set up by dividing the products over the reactants and powering to the stoichiometric coefficient, we can proceed as follows:
a. 2 Ba + O2 ⇌ 2 BaO.
[tex]K=\frac{[BaO]^2}{[Ba]^2[O_2]}[/tex]
b. 2 Mg + O2 ⇌ 2MgO
[tex]K=\frac{[MgO]^2}{[Mg]^2[O_2]}[/tex]

The chemical equation, Cr + Fe(NO3)2 → Fe + Cr(NO3)3, is an example of which type of reaction?
Answers
Answer:
Redox type
Explanation:
The reaction is:
2Cr + 3Fe(NO₃)₂ → 2Fe + 2Cr(NO₃)₃
2 moles of chromium can react to 3 moles of iron (II) nitrate in order to produce 2 moles of iron and 2 moles of chromium nitrate.
If we see oxidation state, we see that chromium changes from 0 to +3
Iron changed the oxidation state from +2 to 0
Remember that elements at ground state has 0, as oxidation state.
Iron is being reduced while chromium is oxidized. Then, the half reactions are:
Fe²⁺ + 2e⁻ ⇄ Fe (Reduction)
Cr ⇄ Cr³⁺ + 3e⁻ (Oxidation)
When an element is being reduced, while another is being oxidized, we are in prescence of a redox reaction.

Calculate the number of moles of NaOH contained in 250. mL of a 0.05M solution.
Answers
Answer:
0.0125mol
Explanation:
Molarity (M) = number of moles (n) ÷ volume (V)
n = Molarity × Volume
According to this question, a 0.05M solution contains 250 mL of NaOH. The volume in litres is as follows:
1000mL = 1L
250mL = 250/1000
= 0.250L
n = 0.05 × 0.250
n = 0.0125
The number of moles of NaOH is 0.0125mol.

Explanation:
H . + H . -----> H:H {":" represents a covalent bond, that is, a shared pair of electrons}
A Lewis structure is a convention used to represent the covalent bonding in a molecule. Dots or lines are used to represent
valence electrons (electrons available for bonding). The Lewis structure for the hydrogen molecule is as follows.
H:H or H-H
A bonding pair is an electron pair shared between two atoms.
A nonbonding pair (lone pair, unshared pair) is a pair of electrons that remains on one atom and is not shared.

How much H2O is produced when 40000 g of
C2H, burns completely?
Answer in units of g.
Answers
Answer:
1200g H20.
Explanation:
Write out the balanced equation... when an organic compound is burned, like C2H2, it is burned in oxygen (O2) and produces Water and Carbon Dioxide (CO2)
so 2C2H2 + 5O2 = 2H2O + 4CO2
now that you have a balanced equation just convert to moles and solve
2000g C2H2 * 1mol C2H2 / 30gC2H2 * 2mol H2O/2mol C2H2 * 18gH2O/1molH20 = 1200g H20.
What results when equal but opposite charges are present in two regions of a polar molecule? A. dipole B. ionic bond C. Electron sea D. crystal lattice
Answers
Answer: A. dipole
Explanation:
Dipole can be defined as the separation of the equal and opposite charges present in the molecule via ionic bonding. The water molecule comprising of two molecules of hydrogen being positively charged and one molecule of oxygen being negatively charged are connected via ionic bonding thus water molecule is an example of dipole molecule. There is unequal distribution of the electrical density throughout the molecule.
The polar molecule results in a dipole when equal but opposite charges are present in two regions.
Dipole:
Dipole arises when a molecule have opposite and equal charge in the ends.
For example - water molecule
In water molecule Oxygen is negatively charged and hydrogen have low electronegativity, this difference in electronegativities arise dipole in molecule.
Therefore, the polar molecule results in a dipole when equal but opposite charges are present in two regions.
