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%

The _energy of the baseball is the sum of the kinetic energy and _energy of the particles that make up the baseball
Answer:
Mechanical energy
Kinetic energy
Explanation:
The mechanical energy is the sum of the kinetic and potential energy of the particles that make up the baseball.
Mechanical energy is made up of kinetic energy and potential energy. When the baseball is in motion, the particles make use of the kinetic energy, also known as motion energy and when the ball is not in motion the particles make use of the potential energy, also known as stored energy.
A bottle of shampoo is shaped like a right cylinder. The cylinder is six inches high with a radius
of 0.9 inches. One cubic inch is the same as 16.4 milliliters. What is the capacity of the bottle in
milliliters? Round to the nearest whole number. Use the following formula to help you decide:
Vegy = 17p• where Vcy is the volume of a right cylinder, ne is about 3.14, ris the radius
of the base, and h is the height of the cylinder
A 250 ml
B 200 ml
C 150 ml
D 100 ml
Answer:
A) 250 ml
Explanation:
Vcyl= π • r2 • h -----> Vcyl= π· 0.9^2 · 6= 15.2681402964464 x 16.4 millimetres = 250.3975008617209 rounded off to 250 millimetres :)
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

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.

If the theoretical yield of a reaction was calculated to be 42.6 grams and when the
experiment was conducted the amount produced was 20.7 grams, the what is the percent
yield of the experiment?
Answer:
48.59%
Explanation:
theoretical yield = 42.6g
actual yield = 20.7g
% yield = 20.7/42.6 x 100 = 48.59% (2 d.p.)
Which best explains why fungi are often called natural recyclers?
They provide a continuous food resource for many other organisms.
They break down rotting materials and return nutrients to the soil.
They take in large amounts of carbon dioxide, helping to clean the air.
O They are found in nature and have many different practical uses,
They break down rotting materials and return nutrients to the soil.
( They don't do photosynthesis since they are much different from plants)
Answer:
B
Explanation:
Given 5 Moles of H20. how many moles of O, are produced. Use the following Equation
2H2+O2->2H2O
Moles O2 required : 2.5
Further explanationGiven
Reaction
2H2+O2->2H2O
Required
Moles of O2
Solution
The reaction coefficient in a chemical equation shows the mole ratio of the reacting compounds (reactants or products)
From the equation, mol ratio of H2O : O2 = 2 : 1, so moles O2 :
= 1/2 x mol H2O
= 1/2 x 5 moles
= 2.5 moles

Identify a human activity that impacts the land negativaly. Then describe a positive action that can help reduce the effects caused by the activity
Answer:
Pollution
•The number of trips one takes in a car should be reduced.
•Reduce or eliminate fireplace and wood stove use.
•Burning leaves, trash, and other materials should be avoided.
•Using gas-powered lawn and garden equipment should also be avoided.
In an ecosystem, pollution is a human activity that impacts the land negatively.Minimum use of vehicles and emission of smoke can help reduce the effects caused by the activity.
What is an ecosystem?An ecosystem is defined as a system which comprises of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through means of nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the ecosystem .Living organisms also influence the quantity of biomass which is present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

The pictures below show samples of different substances.
The mass and volume of each sample differ from the mass and volume of the other samples. Is it possible for each sample to contain 1 mol of each substance?
A. No, because they have different masses.
B. No, because they have different volumes.
C. Yes, if each sample contains 6.02 x 10^23 atoms.
D. Yes, if each sample contains 2 amu.
Answer:
C. Yes, if each sample contains 6.02 x 10²³ atoms.
Explanation:
It is possible for each sample to contain 1 mole of each sample if and only if each of the sample if made up of 6.02 x 10²³ atoms.
6.02 x 10²³ atoms is the Avogadro's number. This number is equivalent to a mole of a substance.
If the amount of matter in the given substance is at least one mole, it is possible that they are made up of one mole each of each substance. If they contain lesser amount of atoms, then it is not up to one mole of substance. But if it is greater, then, we can have even more than one mole of substance.A mole is simply a unit of measurement and it is equivalent to 6.02 x 10²³ atoms.
