Answer: double displacement

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

The balanced chemical equation is:

[tex]3ZnS+2AlP\rightarrow Zn_3P_2+Al_2S_3[/tex]

Thus as ions get exchanged , it is double displacement reaction.

10. The wavelength of the color red is 650 × 10⁻⁹ m

11. The frequency of the color red is approximately 4.6122 × 10¹⁴ Hertz

12. The corresponding energy  is approximately 3.058 × 10⁻¹⁹ J

Explanation:

10. Given that the wavelength, λ, of the color red is 650 nm, and one nanometer, nm = 10⁻⁹ m, we have;

The wavelength of the color red = 650 × 10⁻⁹ m

11. The frequency, v, of the color red is obtained from the relation, v = c/λ

Where;

c = The speed of light = 299,792,458 m/s

∴ v = 299,792,458/(650 × 10⁻⁹) ≈ 4.6122 × 10¹⁴ Hertz

12. Given that energy emitted by light, E = h × v, where E = 6.63 × 10⁻³⁴ J/s, we have;

E = 6.63 × 10⁻³⁴ J·s × 4.6122 × 10¹⁴ Hz ≈ 3.058 × 10⁻¹⁹ J

Therefore,  the corresponding energy, E ≈ 3.058 × 10⁻¹⁹ J.

The volume using the cylinder formula  : V=πr²h

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

This experiment is an illustration of Charles's law, to determine the relationship between temperature and gas volume

If a certain amount of gas is heated, the volume will increase

So in this experiment, the temperature was changed as an independent variable and tube volume as a fixed variable

Because the tube is cylindrical, to find the volume using the cylinder formula

[tex]\tt V=\pi.r^2.h[/tex]

Meanwhile, to find the radius, you can use a caliper to measure the diameter of the tube and the result will be divided by 2

Explanation:

Answer:497J/kg/K

Explanation:

Use the equation: Q=mS◇T

According to specific heat capacity, the specific heat of glass is 0.4970 J/gK.

Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.

It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.

It is given by the formula ,

Q=mcΔT

Substituting values in above equation, c=Q/mΔT, C=840/65×26=0.4970 J/gK.

Thus, the specific heat of glass is 0.4970 J/gK.

Answer: I think the answer is The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes.

Explanation: Because the muscles would make the food smaller and the enzymes have a chemical change to it because it changes the molecules in the food.

The chemical processes in food digestion results in the formation of new

substances.

The statement that best describes the changes in food during digestion is;

The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.

Reasons:  

The given processes in the digestion of food are;

Stomach: Food churning is the process by which the small intestine vigorously turns ingested food.

Small intestine: The action of the peptidase enzyme is to increase the rate of the digestion of food.

Therefore;

Answer:

ow many atoms are there in 1g of argon the Avogadro constant is 6.02 x 10^23 per mole relative atomic mass (Ar): AR=40Explanation:

The number of atoms of argon in 1g of argon is 1.5 × 10²² atoms

From the question,

We are to determine the number of atoms present in 1g of argon.

To determine this,

First we will calculate the number of moles of the 1g of argon

From the formula

[tex]Number\ of\ moles = \frac{Mass}{Atomic\ mass}[/tex]

From the given information

Mass of Argon = 1g

Atomic mass of Argon = 40g/mol

∴ Number of moles of Argon = [tex]\frac{1}{40}[/tex]

Number of mole of Argon = 0.025 mole

Now,

For the number of atoms of argon present

Using the formula

Number of atoms = Number of moles × Avogadro's constant

∴ Number of atoms of argon present = 0.025 × 6.022×10²³

Number of atoms of argon present = 1.5055 × 10²² atoms

Number of atoms of argon present ≅ 1.5 × 10²² atoms

Hence, the number of atoms of argon in 1g of argon is 1.5 × 10²² atoms
