a snow-plowing service
a cosmetics factory
a pottery art studio
a catering business
Answers
Answer:
cosmetics factory
Explanation:
The company owned by Hsaio has been most likely to be the cosmetic factory. Hence, option B is correct.
What is a cosmetics factory?A cosmetic manufacturer is a company that manufactures cosmetic items. The products manufactured by the cosmetic industry include soap, shampoo, and toothpaste that smell good, such as perfume and deodorant.
The cosmetic industry products are formed to be viscous in nature, in order to be applied with ease in personal care. Calcium chloride has been the chemical agent that has been mediating to add viscosity to cosmetic products.
Since, Hsaio has been incorporating most of the budget of his company over calcium chloride, a product used in the cosmetic industry. Thereby he is most likely to own a cosmetic factory. Hence, option B is correct.

The airplane's flight time is the outcome variable (dependent variable), the wind speed is the test variable (independent variable), and the airplane is the constant.

The airplane's flight time is the test variable (independent variable), the airplane is the outcome variable (dependent variable), and the wind speed is the constant.
Answers
Answer:
i am pretty sure the answer is a
Explanation: because the airplane's flight time has to be the independent variable for it to affect the dependent variable that is the speed of how fast the airplane is going.
Independent variables are test variables where we are testing its effects on the dependant variables. Here wind speed is the independent variable and time of flight is dependant variable.
What are variables?Variables are values or components in an experiment which can be measured and will change by time. In an experiment there are two kinds of variables namely independant and dependant variables.
Dependant variables are those which changes with effect of independent variables. For example if we are studying the effect of water quality in the population of fish in a pond. The independent variable is the quality of water and fish population is the dependent variable.
Here the time of flight depends on the wind speed. Thus, flight time is the dependant variable and wind speed is the test variable or independent variable.

cal the vol of carbon(ii)oxide produced at stp by. d dehydration of 6.00g of methanoic acid with concentrated H2SO4 carbon=2 oxygen=16 hydrogen=1
molar volume = 22.4dmcube
Answers
The volume of CO= 2.912 L
Further explanationGiven
Dehydration of 6 g of methanoic acid with H2SO4
Required
The volume of CO
Solution
Reaction
HCOOH ⇒ CO+H₂O
MW = 1.Ar C+2.Ar H+2.Ar O
MW = 1.12+2.1+2.16
MW= 46 g/mol
mol = mass : MW
mol = 6 g : 46 g/mol
mol = 0.13
From equation, mol ratio HCOOH : CO, so mol CO = 0.13
Vm = 22.4 L
so for 0.13 mol :
= 0.13 x 22.4 L
= 2.912 L
Several balloons are inflated with helium to a volume of 0.75 L at 27°C. One of the balloons was found several
hours later, the temperature had dropped to 22°C. What would be the volume of the balloon when found, if no
helium has escaped? (0.74L)
Answers
Answer:
V₂ = 0.74 L
Explanation:
Given data:
Initial volume of balloon = 0.75 L
Initial temperature of balloon = 27°C (27+273.15 K = 300.15 K)
Final volume of balloon = ?
Final temperature = 22°C (22+273.15 K = 295.15 k)
Solution:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 0.75 L × 295.15 k / 300.15 K
V₂ = 221.36 L.K / 300.15 K
V₂ = 0.74 L
The given problem is solved through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:

What are valence electrons and why are they important to know about for bonding of atoms into molecules?
Answers
Answer:
valence electrons are the electron in an outermost shell of an atom of an element (it is also called the outermost electron).
They are important for bonding because, when you bond two or more atom of an element, it is the outermost electron (valence electron) that will do the sharing of electrons when two atoms are bonded together.

What does the calculated value of the equilibrium constant, Keq indicate regarding the degree of completeness of the reaction? In other words, at equilibrium, are there mostly products, reactants, or relatively large amounts of both?
Answers
Answer:
both
Explanation:
because equilibrium means that both sides of the reaction are equal
The concentration of the products is high at equilibrium if Keq is a large number (Keq > 1). The reaction in this instance encourages the production of products. The concentration of the reactants is high at equilibrium if Keq is a small number (Keq1).
What is equilibrium ?Chemical equilibrium is the condition where both the reactants and products are present in concentrations that have no further tendency to change over time, preventing any discernible change in the system's properties.
The size of a reaction when it is at equilibrium is represented by the equilibrium constant, K. It creates a ratio using the concentrations and coefficients of each reactant and product.
K is regarded as intermediate if it is larger than or equal to 0.001 but less than or equal to 1000. Significant quantities of reactants and products will be present. When the equilibrium constant K is big, products predominate at equilibrium, but when it is small, reactants predominate.
Thus, The concentration of the products is high at equilibrium if Keq is a large number.

10.8 g of aluminium reacts with excess oxygen to form aluminium oxide: 4Al + 3O2 → 2Al2O3. What is the theoretical yield of aluminium oxide? (Relative masses: Al = 27.0, Al2O3 = 102.0)
Answers
Answer:
Theoretical yield = 40.8g
Explanation:
4Al + 3O2 ----] 2Al2O3
if 27.0g of Al ----] 102.0g of 2Al2O3therefore 10.8g -----] xg10.8g×102.0g/ 27.0g
theoretical yield = 40.8 g
Answer:
20.410 grams of Al2O3 are produced
Explanation:
First, we need to calculate the number of moles of aluminum that are actually reacting..
We will convert from grams to moles using the atomic weight which (for aluminum) is 26.982 g/mol (which can also be rewritten as 1 mol/26.982)
10.8 g Al * 1 mol Al/26.982 g Al = 0.4002668446 moles Al
**Grams cancel out, so we are left with moles
(I would type this differently so that it would make more sense visually, however brainly is giving me errors, so try writing it out yourself if it doesn't initially make sense..put the equation in fraction form)
Now that we have the moles of Al, we will convert from moles of Al reacting to moles of aluminum oxide produced..
To do this we will use the balanced chemical equation..
4Al + 3O2 -> 2Al2O3
Using the balanced chemical equation, we can see that for every 4 moles of aluminum that react, 2 moles of aluminum oxide are produced..
0.4002668446 moles Al * 2 mol Al2O3 / 4 mol Al
= 0.2001334223 moles Al2O3..
Now we need to convert from moles of Al2O3 to grams..
We can do this using the atomic weight of Al2O3..
The atomic weight of Al2O3 is 101.961 g/mol or 1 mol/101.961 grams
Now we will convert to grams of Al2O3...
0.2001334223 moles Al2O3 * 101.961 grams Al2O3/1 mol Al2O3
= 20.40580387..
20.410 grams of Al2O3 are produced
