it would be ionic
copper forms a cation and oxygen forms an anion
those charges represent the e-s that are transferred during bonding
oxygen is -2 so will accept 2 e-s to achieve noble gas configuration

how many grams are in 7.4 moles of HgS?
Answer: 1721.6 grams
Explanation:
Suppose you weigh the unknown substance on an electronic balance and find it has a mass of 445 grams. Analyzing the products of decomposition, you find that the masses of the elements in the sample are 232 grams of carbon, 58 grams of hydrogen, and 155 grams of oxygen. Finally, through further experimentation, you determine that the molar mass of the compound is 46.07 grams/mole.
Calculate the amount, in moles, of each component element in your substance. Use the periodic table to help you find the necessary molar masses.
____ moles of carbon
____ moles of hydrogen
____ moles of oxygen
Answer:
19.32 = moles of carbon
57.54 = moles of hydrogen
9.69 = moles of oxygen
Explanation:
232 g carbon × 1 mol C / 12.011 g C= 19.32 mol C
58 g hydrogen × 1 mol H / 1.008 g H = 57.54 mol H
155 g oxygen × 1 mol O / 15.999 g O = 9.69 mol O

How Many Moles of CO2 can be produced by reacting 6 moles of C3H7OH with oxygen?
Answer:
Up to [tex]18\; \rm mol[/tex] [tex]\rm CO_2[/tex].
Explanation:
The equation for this reaction: [tex]2\; \rm C_3 H_7 OH + 9\; O_2 \to 6\; CO_2 + 8\; H_2O[/tex] is indeed balanced.
Notice that the coefficient of [tex]\rm C_3 H_7 OH[/tex] is [tex]2[/tex] while that of [tex]\rm CO_2[/tex] is [tex]6[/tex].
Therefore, each unit of this reaction would consume [tex]2[/tex] units of [tex]\rm C_3H_7OH[/tex] while producing [tex]6[/tex] units of [tex]\rm CO_2[/tex]. In other words, this reaction would produce three times as much [tex]\rm CO_2\![/tex] as it consumes [tex]\rm C_3H_7OH\![/tex].
If all that [tex]6\; \rm mol[/tex] of [tex]\rm C_3H_7OH[/tex] molecules are actually consumed through this reaction, three times as many [tex]\rm CO_2[/tex] molecules would be produced. That corresponds to [tex]3 \times 6\; \rm mol = 18\; \rm mol[/tex] of [tex]\rm CO_2\![/tex] molecules.

Give examples of Avogadro, Boyle, and Charle's law.
Answer:
You can observe a real-life application of Boyle's Law when you fill your bike tires with air. When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it starts to push against the walls of the tire.
Tyres of untouched vehicles get deflated during freezing winter days while get inflated in hot summer days. This unusual behaviour is because of Charles's law. In winter due to low temperatures, the air inside a tyre gets cooler, and they shrink. While in hot days, the air expands with temperature.
Another common example of Avogadro's law is the deflation of automobile tyres. When the air trapped inside the tyre escapes, the number of moles of air present in the tyre decreases. This results in a decrease in the volume occupied by the gas, causing the tyre to lose its shape and deflate.

Five moles of trucks would be____trucks.
Answer:
3.02x10²⁴
Explanation:
To solve this problem we need to use Avogadro's number: It is the number of units (usually atoms or molecules, in this case it's trucks) contained in one mol: 6.023x10²³.
We multiply the given number of moles times Avogadro's number:
5 * 6.023x10²³ = 3.02x10²⁴
So five moles of trucks would be 3.02x10²⁴ trucks.
What is the phenotype of a plant with the genotype RR?
Red
White
O
Pink
Answer:
This question is incomplete, but it can be answered based on general knowledge of the topic. The answer is RED
Explanation:
This question is describing a gene that codes for color. The allele for red color is R while that of white is r, however, these two alleles exhibit incomplete dominance to form an intermediate phenotype that is PINK (Rr).
Since the heterozygous is pink color, it will take two red alleles to make a plant phenotypically red i.e RR. Note that, genotype "rr" will be white.

Define unknown solutions
Answer:
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte until the reaction is complete
Plz help thank you!!!
Answer:
1. Covalent Bond
2. Ionic Bond
Explanation:
Covalent bonds are defined as the bond in which sharing of electrons takes place between atoms. The sharing of electrons is in equal number so that it form a stable balance of attraction and repulsion between atoms. In the given example of CO2 (first image) oxygen is sharing equal number of electrons with carbon to form a stable bond called covalent bond.
Ionic bonds are formed when valence electrons are transferred to other atoms and form oppositely charged ions. In ionic bond formation, the atoms that gain electrons become negatively charged and the atoms that loses electrons become positively charged. In the given example of Ca Cl2, Ca is also giving its 2 valence electrons to each Cl and there is no stable balance of attraction and repulsion between atoms.
Hence, the correct answer is:
1. Covalent Bond
2. Ionic Bond

2. Find the molar mass for:
FeCl2 • 5H20
Answer:
Molar mass = 216.8254 (approx.)
Explanation:
Given:
FeCl2 • 5H20
Find:
Molar mass
Computation:
Atomic mass
Fe = 55.845
Cl = 35.453
H = 1.00794
So,
FeCl2 • 5H20
55.845 + 2(35.453) + (2)5(1.00794) + 5(15.999)
55.845 + 70.906 + 10.0794 + 79.995
Molar mass = 216.8254 (approx.)

How many liters are in 100g of CoCl2
Is it 579.60L
is it 29.08 L
Is it 23.73 L
Is it 17.25 L
Answer:
17.25 L
Explanation:
I converted 100g into moles and converted the amount of moles into L.
1 mole is equal to 6.023 × 10 ²³ molecules.17.25 Liters are in 100 grams of COCl₂. Therefore, option D is correct.
What do you mean by mole ?The term mole is defined as the amount of substance of a system which contains as many elementary entities.
One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.
The mole concept can be used to convert between mass and number of particles.
1 gram of COCl₂ = 0.00770 mole
100 gram COCl₂ = 0.770 mole
To convert gram into litre multiply by 22.4
= 0.770 × 22.4
= 17.25 Litre
Thus, 17.25 Liters are in 100 grams of COCl₂, option D is correct.
