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.

3Ca₍s₎ + 2FeCl₃ ------------------------------------------------------------->  3CaCl₂ + 2Fe₍s₎.

Explanation:

Iron(III) chloride is also known as Iron trichloride and it has the molar mass value of 162.2 g/mol and density of 2.9 g/cm³.

The balanced equation for the chemical reaction between solid calcium and iron (III) chloride is given below as:  

3Ca₍s₎ + 2FeCl₃ ------------------------------------------------------------->  3CaCl₂ + 2Fe₍s₎.

This kind of chemical reaction is known as single displacement reaction or single replacement reaction.

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:

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:

A. A skin cell has a less complex structure than skin tissue has.

Explanation:

A skin cell has a less complex structure than skin tissue has. Hence option A is correct.

Cell is defined as the smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. The three essential parts of a cell are the cell membrane, nucleus, and cytoplasm. From bacteria to humans, cells give all living things their structure and functionality.

The tiniest, structurally and functionally distinct, and typically microscopic, unit of an organism is called a cell. The several forms of material made up of specialized cells and their byproducts are referred to as tissues. Cells are very small. The size of tissues is macro.

Thus, a skin cell has a less complex structure than skin tissue has. Hence option A is correct.

Explanation:

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:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

It means when we increase the temperature volume is also goes to increase and vice versa.

Let's consider the example,

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 4.5 L × 348 K / 298 k

V₂ = 1566 L.K / 298 K

V₂ = 5.3 L

We can see when temperature is increase from 298 K to 348 K volume is also increased from 4.5 L to 5.3 L.

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.

Explanation:

To solve this problem we need to convert the liters of fat removed to mL. Using the mL and density we can find the grams. To convert grams to pounds we must use (1lb = 453.592g):

mL fat:

4.0L * (1000mL / 1L) = 4000mL

g fat:

4000mL * (0.94g / mL) = 3760g of fat
