Answer:

cosmetics factory

Explanation:

The company owned by Hsaio has been most likely to be the cosmetic factory. Hence, option B is correct.

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.

Answer:

Theoretical yield = 40.8g

Explanation:

4Al + 3O2 ----] 2Al2O3

10.8g×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

Answer:

f = 6 × 10^15 Hz in the ULTRAVIOLET (UV) region

Explanation:

Using λ = v/f

Where;

λ = wavelength (m)

v = speed of light (3 × 10^8m/s)

f = frequency (Hz)

According to this question, λ = 5.00 x 10^-6 cm

= 5.00 x 10^-8 m

λ = v/f

f = v/λ

f = 3 × 10^8 ÷ 5.00 x 10^-8

f = 0.6 × 10^(8+8)

f = 0.6 × 10^16

f = 6 × 10^15 Hz

In the electromagnetic spectrum (EM), a frequency of 10^15 is found in the ULTRAVIOLET region. This means that this radiation with a wavelength of 5.00 x 10^-6 cm and frequency of 6 × 10^15 Hz is in the ULTRAVIOLET region of the EM spectrum.

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).

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.

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.

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.

The volume of CO= 2.912 L

Given

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

Answer:

35.5

Explanation:

Given parameters:

Abundance of chlorine Cl  - 35 = 75%

Mass of Cl - 35 = 35

Abundance of Cl - 37  = 25%

Mass of Cl - 37 = 37

Unknown:

Relative molecular mass  = ?

Solution:

The relative molecular mass of the chlorine can be deduced using the expression below:

   Relative molecular mass  = (abundance x mass of Cl - 35) + ( abundance x mass of Cl - 37)

 Relative molecular mass  = (75% x 35) + (25% x 37)  = 35.5

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
