A compound is found to contain 64.80 % carbon, 13.62 % hydrogen, and 21.58 % oxygen by weight. What is the empirical formula for this compound
Answer:
Empirical formula is C₄H₁₀O
Explanation:
Values for C, H and O are determined as centesimal composition.
64.80 g of C in 100g of compound
13.62g of H in 100 g of compound
21.58 g of O in 100 g of compound.
We convert the mass to moles:
64.80 g . 1mol/ 12g = 5.4 moles of C
13.62 g . 1 mol /1g = 13.62 moles of H
21.58 g . 1 mol/16g = 1.35 moles of O
We pick the lowest value and we divide:
5.4 moles of C / 1.35 = 4 C
13.62 moles of H / 1.35 = 10 H
1.35 moles of O / 1.35 = 1 O
Empirical formula is C₄H₁₀O, it can be the diethyl ether.
We confirm, the excersise is well done.
Molar mass = 74g/mol
74 g of compound we have (12 . 4)g of C
In 100 g of compound we may have (100 . 48) / 74 = 64.8 g
A cupcake recipe designed to produce 18 cupcakes calls for 260 grams of
flour. Determine the quantity of flour that would be required to make 22
cupcakes. (Round the final answer to four decimal place.)
Answer:
317.7778 g
Explanation:
Given data:
Flour required for 18 cup cakes = 260 g
Flour required for 22 cup cakes = ?
Solution:
We will calculate the flour required for 1 cup cake.
260 g /18 = 14.4444 g
Fluor required for 22 cupcakes,
22× 14.4444 g = 317.7778 g
In short,
22 cupcake/18 cup cake×260 g = 317.7778 g

A forest area is being used for a new housing development. Most of the trees have been removed to make room for the
new houses, Predict the impact that this will have on the birds in the area.
Answer:
The correct answer would be - lose their native habitats are forced to migrate into new areas in search of shelter and food.
Explanation:
The removal of trees or deforestation to build a housing or city planning or development impact the birds and other animals of that area. Cutting most of the trees from the area will result in a decrease in available food, shelter, and breeding habitat.
It causes complete removal of bird species and forced them to migrate to a new place in search of places that will provide a source of shelter and food for birds.
Water is one of the most important resources for humans. Some areas are known to have no water shortages, where other areas are now suffering the scarcity of water. List some factors that change the distribution of water abundance.
(written response)
Answer:
The factors are various, although there are main and accessories.
The main factor is the climate of the area, that is, if it is a rainier climate, there will be more water masses in the lands where this climate abounds (usually it is wet).
Other factors are: geographical features, flows, the path of rivers, lakes or lagoons, the presence or absence of ports, the number of trees and the distribution of rocks.
Explanation:
Another important factor is the height of the land, the higher the level of the earth, the more difficult it will be to accumulate water, this is how low areas are also flooded.

Kp for the following reaction is 0.16 at 25 degree C. 2 NOBr(g) 2 NO(g) Br_2(g) The enthalpy change for the reaction at standard conditions is
Answer:
Explanation:
Given that:
[tex]2 NOBr_{(g)} \iff 2 NO_{(g)} + Br_{2(g)}[/tex]
From above:
[tex]K_p = 0.16 = \dfrac{(P_{NO})^2 (P_{Br})}{(P_{NOBr})^2}[/tex]
To predict the effect of the addition of Br₂(g);
The addition of Br₂(g) will favor the equilibrium to shift to the left i.e. formation of NOBr
The removal of some NOBr will cause the equilibrium position to shift to the left side. This is because concentration on the left side is decreased and the concentration on the right side will be increased. Thus, the equilibrium will shift towards where the concentration is reduced which is the left side.

student's results?
A. Low precision, low accuracy
O B. High precision, low accuracy
O C. High precision, high accuracy
O D. Low precision, high accuracy
Answer:
It is D low precision, high accuracy
Explanation:
I got it correct
The Xs show the location of beanbags a student tossed at a target. The student was aiming for the center circle. Low precision, high accuracy best describe the student's results. Therefore, option D is correct.
What is precision ?There are two ways to assess observational error: accuracy and precision. Precision measures how closely two measurements are to one another, whereas accuracy measures how close a group of measurements is to its actual value. In other words, precision is a measure of statistical variability and a description of random errors.
The proximity of two or more measurements to one another is referred to as precision. Using the aforementioned example, your measurement is extremely accurate if you weigh a certain substance five times and obtain 3.2 kg each time. Accuracy is not necessary for precision.
Regardless of whether or whether two or more measurements are correct, precision is described as "the property of being exact" and relates to how close two or more measurements are to one another.
Thus, option D is correct.

A chemist adds of a M calcium sulfate solution to a reaction flask. Calculate the mass in grams of calcium sulfate the chemist has added to the flask
Answer:
1.23 g
Explanation:
A chemist adds 1.55 L of a 0.00582 M calcium sulfate solution to a reaction flask. Calculate the mass in grams of calcium sulfate the chemist has added to the flask.
Step 1: Given data
Volume of the solution (V): 1.55 LMolar concentration of the solution (C): 0.00582 M (0.00582 mol/L)Step 2: Calculate the moles (n) of calcium sulfate added
We will use the following expression.
n = C × V
n = 0.00582 mol/L × 1.55 L
n = 0.00902 mol
Step 3: Calculate the mass corresponding to 0.00902 moles of calcium sulfate
The molar mass of calcium sulfate is 136.14 g/mol.
0.00902 mol × 136.14 g/mol = 1.23 g
A sample of carbon dioxide gas that has a volume of 14.6 L at STP contains how many
mol(s) of gas (to three significant figures).
Answer:
n = 0.651 mol
Explanation:
Given data:
Volume of CO₂ = 14.6 L
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Number of moles of CO₂ = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
by putting values,
1 atm × 14.6 L = n × 0.0821 atm.L/ mol.K × 273.15 K
14.6 L. atm = n × 22.43atm.L/ mol
n = 0.651 mol

(b) High charge on ions, small cation and large anion.
(c)X High charge on ions, large cation and small anion
(d) Low charge on ions, small cation and large anion
bila da
Answer:
A: Low charge on ions, large cation and small anion
Explanation:
Electrovalency is defined as process of transfer of electrons from its valence shell from one atom to another to form ions in such a manner that both elements will achieve stable electronic configuration.
Now cations are positively charged ions and therefore the bigger the cation, the more electrons it looses and thus the more it favors Electrovalency.
While an ions are negative and the lesser they are the more they favor Electrovalency.
Thus, the correct answer is option A

. When a person weighs himself in pounds, which system of measurement is he using?
Answer:
answer: Weight is a 'force' and in the imperial system, it is measured in pounds-force (lbf or lbf). You might hear this term used together with the term 'slug'. A slug has a mass of 32.174049 lb. Explanation:
Explanation:
The unit pound is a unit of mass which is from the British imperial units of measurements. Pound is not included in CGS or SI units of mass.
What is mass?Mass of a substance is its total amount which can be expressed in any units such as g, Kg etc. Our mass is affected by the gravity and thus the total weight of a body is mass multiplied by gravity.
There are different system for units and each units of a measurement is interrelated. Units are very significant in measurements and to identify the variables.
The most commonly used unit system is international system of units called the SI system. Where the mass length and time are in Kg, m and seconds. In CGS system it is gram, meter and seconds.
