Answer
5.6 L
Explanation:
whatever you start with, you end with the same amount.
(LAW OF CONSERVATION)
The amount of oxygen and gasoline that can be produced is 5.6 liters
The question above is answered with the law of conversation of mass. This law of conversation of mass states that no form of energy can be destroyed, instead it is changed from one form to another type of form.
In this law, it is expected that you end with the same amount you started with. According to the question above, since the amount that you started with is 5.6 liters then you will end with 5.6 liters also.

I'm assuming this is from a lab that you did - in which case, I can't really help you out here.
Explanation:
very urgent
1. Describe an experiment to show the chemical effect of electric current.
2. State three conditions necessary for combustion
3. Describe all that you observe when a piece of iron is placed in copper sulphate solution for a
few minutes.
Explanation:
STEP 1- Take two iron nails.
STEP 2- Clean it with sand paper.
STEP 3- Wrap copper wire around both the nails. And connect the other end to the battery terminal.
STEP 4- Take water in beaker and little amount of salt in it or a few drpos of sulphuric acid in it.
STEP 5- Immerse the nails in the solution.
STEP 6- Observe the nails carefully. You can see bubbles of gases coming out from water near nails.
When, electeric current is passed through water gases like hydrogen and oxygen are evolved.
2.Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.
When iron is placed in Copper sulphate solution, the iron is coated with a brown coloured substance "copper" and CuSo4 solution changes from blue to light green. This is due to iron displaces copper as it is more reactive than copper.

20 mL of NaOH solution was added to the conical flask. Indicator was added & titrated with 0.1 M HCl solution. The HCl used in the titration was read as 18.3 mL. What is the molar concentration of NaOH?
Answer:
[NaOH] = 0.1 Molar ... Note => the brackets around formula;i.e., "[ ]" is generally accepted in the chemistry community as concentration in Molar terms.
Explanation:
The metathesis rxn, or double replacement rxn, equation is:
(Molarity x Volume) of acid = (Molarity x Volume) of base, or
(M·V)acid = (M·V)base => M(base) = M·V(acid)/V(base)
= 0.1M × 18.3ml / 20ml = 0.0915M(base) = 0.1M (1 sig-fig) = [NaOH]
what is the correct answer ?
Answer:
Element with 6s subshell
Explanation:
Reactivity of an element depends on the electronic configuration and position of element in the periodic table as reactivity increases as we go down the periodic table.
This is so because number of shell increases as move down the periodic table and the last electron is further away from the nucleus.
Element with 6s subshell is the largest among 3s and 4s subshell and has more number of shells so it will react more than 3s and 4s subshell.
Hence, the correct answer is "Element with 6s subshell".

Explanation:
if 18g H2O is equal to 1 mole then 100 g H2O is how much?
100/18 which is 5.55
Answer:
5.551
Explanation:
100.0g x 1mol H20/18.015g H20 = 5.551 moles of H20
The 18.015g is from the periodic table. H = 1.008x2 = 2.016g H2
0= 15.999
15.999 + 2.016= 18.015

4 description of meteor showers
Answer:
A meteor shower are defined as the celestial event in which a meteor comes from one point in the sky and visible in night sky.
Meteors are also known as Shooting stars as they glow when enters in the Earth surface as glowing streaks, where tail point to the origin in the sky and face faces the Earth surface.
Meteor showers take place when meteoroids entering Earth's atmosphere.
Meteor showers can repeat themselves because it depends on the comet orbits which can take place at the same time each year.

How many grams of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)?
Answer:
[tex]55.1657[/tex] grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
Explanation:
The molecular weight of acetylene is 26.04 g/mol
Molecular weight of carbon is equal to 12.011 g/mol
Two carbon atom produces one acetylene molecule.
Thus, 2 * 12.011 g/mol of carbon is used to produce 26.04 g/mol of acetylene,
Amount of carbon required to produce 59.8 grams of acetylene
[tex]\frac{2*12.011}{26.04} * 59.8 \\= 55.1657[/tex]grams/mol

explain why a nanowire can be longer than 3000nm but still be considered a metallic nanomaterial
Answer:
A nanowire is a nanostructure, with the diameter of the order of a nanometre (10−9 meters). It can also be defined as the ratio of the length to width being greater than 1000. Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important—which coined the term "quantum wires". Many different types of nanowires exist, including superconducting (e.g. YBCO[1]), metallic (e.g. Ni, Pt, Au, Ag), semiconducting (e.g. silicon nanowires (SiNWs), InP, GaN) and insulating (e.g. SiO2, TiO2). Molecular nanowires are composed of repeating molecular units either organic (e.g. DNA) or inorganic (e.g. Mo6S9−xIx).

trioxocarbonate 4
Answer:
H2SO4 cannot be used with CaCO3 to produce CO2 gas
Explanation:
Because it does not dissolve in water- it forms a barrier on the surface of the unreacted CaCO3 which prevents any further reaction. A small volume CO2 is produced, this stops in short time.

Answer:
Sexual reproduction involves male and female sex cells known as - Gametes
Explanation:
In sexual reproduction new organisms are produced from the fusion of a male sex cell with a female sex cell. This fusion of gametes is called fertilisation. Sex cells are also known as gametes. Male gametes are made by male reproductive structures. Female gametes are made by female reproductive structures.

For the rxn CaCo3(s)+2Hcl(aq)_CaCl(aq)+Ca2(g)+H2O(l)68.1 g solid CaCo3 is mixed with 51.6Hcl what number of grams of Co2 will be produced
Answer:
29.9 g of CO₂ will be produced by the reaction.
Explanation:
This is the reaction:
CaCO₃(s) + 2HCl (aq) → CaCl₂(aq) + CO₂(g) + H₂O(l)
First of all, we state the moles of each reactant:
68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate
51.6 g . 1 mol/36.45g = 1.46 mol of acid.
The solid salt is the limiting reactant. Ratio is 2:1
2 moles of acid can react to 1 mol of salt
1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles
As we only have 0.680 moles of salt, we do not have enough.
Let's work at the product side. Ratio is 1:1
1 mo of salt can produce 1 mol of gas
0.680 moles will produce 0.680 moles of gas
We convert the moles to mass → 0.680 mol . 44g / 1mol = 29.9 g of CO₂
The number of grams of Co2 should be produced is 29.9 g.
Calculation of the number of grams:Since
CaCO₃(s) + 2HCl (aq) → CaCl₂(aq) + CO₂(g) + H₂O(l)
So,
68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate
51.6 g . 1 mol/36.45g = 1.46 mol of acid.
Now the ratio should be 2:1 for the solid salt
And, there is 2 moles of acid can react to 1 mol of salt
So,
1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles
Now the product side the ratio is 1:1
So, that means
1 mo of salt can produce 1 mol of gas
So, the no of grams should be
= 0.680 mol . 44g / 1mol
= 29.9 g of CO₂
