How many moles of Fe2O3 were used to produce with 11.5 moles of CO2 ?
Moles of Fe2O3 used : 3.83
Further explanationGiven
11.5 moles of CO2
Required
moles of Fe2O3
Solution
Reaction
Fe2O3 + 3CO ⇒2Fe + 3CO2
The reaction coefficient shows the mole ratio of the reacting compound (reactants or products)
From the equation, mol ratio of Fe2O3 : CO2 = 1 : 3, so mol Fe2O3 :
= 1/3 x moles CO2
= 1/3 x 11.5
= 3.83 moles
Along with maintaining structure and reproduction, what is the third item that all living things face as a challenge? Question 3 options: How to socialize appropriately How to social distance effectively How to get enough sleep. How to get enough energy for daily life
Answer:
So the answer is gonna be how to get enough energy for your daily life
Explanation:
Sometimes the human body cant get enough energy from the food and protein the food gives out.

Nucleus Nucleus Atom 1 Atorn 2 Nucleus Nucleus Atom 3 Atom 4 Which two atoms are of elements in the same group in the periodic table?
Explanation:
The atoms of elements on the same period on the periodic table typically have the same number of valence electrons.
They have the same electronic configuration.
Valence electrons are electrons in the outermost shell of an atom.
The number of electrons in an atom is a good indicator of elements that might potentially belong to the same group.
Atoms of which two elements have a combined total of 23 protons?
A.Sodium, Na, and magnesium, Mg
B.Boron, B, and carbon, C
C.Copper, Cu, and zinc, Zn
D.None of these
Answer:
A
Explanation:
Sodium has 11 electrons and Magnesium has 12 electrons. Since here you need to consider atoms, they must have equal amount of protons as electrons to be considered neutral, and so an atom.
So simply 11+12 =23

One mole of zinc has a mass of 65.4 grams. Approximately how many atoms of zinc are present in one mole of zinc?
Answer:
6.02 x 10²³ atoms
Explanation:
The number of moles present in 1 mole of zinc will be 6.02 x 10²³ atoms. This is because a mole of any substance contains the Avogadro's number of particles which is 6.02 x 10²³ atoms.
A mole is simple a convenient way of estimating the number particles within a substance.
So every 1 mole of a substance contains the same number atom in there.
For the give zinc, since it is 1 mole, it will contain 6.02 x 10²³ atoms
they've changed the answer, but 6.02 x 1023 is still right. the new answer is just 6 x 1023.(6.02 rounded to the nearest integer)
what does aqueous mean
of or containing water, typically as a solvent or medium.
"an aqueous solution of potassium permanganate"
like water; watery.
"a great hall of aqueous marble"
A process that releases heat, such as freezing or condensation is called?
Answer:
exothermic
Explanation:
An exothermic reaction gives off heat energy. Condensation is the process by which water vapor turns into liquid water. This typically occurs when water vapor molecules come into contact with cooler molecules. This causes the water vapor molecules to lose some energy as heat which is a exothermic reaction.
When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction.
Which of these elements has the highest first ionization energy
A) oxygen
B) beryllium
C) fluorine
D) carbon
E) boron

Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site.
Explanation:
For the balanced equation shown below, if the reaction theoretically
should produce 7.99g CaO but experimentally produces 6.81 grams of
CaO, what is the percent yield?
CaCO3---->CaO+CO2
85.23%
0 14.77%
54.41%
O 117.33%
Answer:
Percent yield = 85.23%
Explanation:
Given data:
Theoretical yield = 7.99 g
Actual yield = 6.81 g
Percent yield of CaO = ?
Solution:
Formula:
Percent yield = ( actual yield / theoretical yield ) × 100
by putting values,
Percent yield = (6.81 g/ 7.99 g) × 100
Percent yield = 0.8523× 100
Percent yield = 85.23%

Which of the following is an example of the reflection of waves?
A)getting a sunburn
B)Your image in a mirror
C)light through the sunroof of a car
D)The movement of a sailboat
Answer:
C
