H₂S? (H = 1, S = 32)

The Chemical Formula For Hydrogen Sulfide Is HS. What Is The Mass Of Hydrogen In 150 G OfHS? (H = 1,

Answers

Answer 1

The chemical formula for hydrogen sulfide is H₂S. The mass of hydrogen in 150 g of 141.2 g. Therefore, option A is correct.

What is mass ?

A body's mass is an inherent quality. Prior to the discovery of the atom and particle physics, it was widely considered to be tied to the amount of matter in a physical body.

Simply put, mass is a measurement of a body's amount of matter. Matter is everything that has both volume and mass. Although mass cannot be seen, it can be measured or quantified. Not all matter is visible. Typically, mass is expressed in kilograms, etc.

Molar mass of  H₂S

= 1 × 2 + 32

= 34

The mass of hydrogen in 150 g is 141.2 g.

Thus, option A is correct.

Plate Tectonics Independent Practice,
Label The Diagram With The Correct Information.

Answers

Answer:

1st Diagram (at the left) → Mid-Atlantic Ridge

2nd Diagram (at the right) → Andes Mountains

3rd Diagram (below) → San Andreas Fault

Explanation:

I have been able to label the diagram with the correct information.

The 1st diagram at the left is the Mid-Atlantic Ridge. This is a divergent plate boundary that is found at the floor of the Atlantic Ocean. It is also seen as part of the mountain range in the world. The Mid-Atlantic Ridge also includes a deep rift valley. This rift valley runs along the axis of the ridge. This is along nearly its entire length.

The Andes Mountains is found along the Pacific Ring of Fire. It is seen in a Mesozoic–Tertiary orogenic belt of mountains. The Andes rises due to the compression of the western rim of the South American Plate. It is a result of tectonic plate processes.

San Andreas Fault is known to form the tectonic boundary which exists between the Pacific Plate and the North American Plate. The motion of the fault is right-lateral strike-slip. It divides into three segments.

What is chemical equation?

In chemistry, you will frequently come across a chemical equation. It is a textual depiction of the procedure that takes place throughout a chemical reaction using numbers and symbols.

The reactants are placed on the left side of such an arrow in a chemical equation, while the reaction's products are placed on the right. Though certain equations may imply equilibrium with the reaction occurring in both directions simultaneously, the tip of the arrow normally heads toward the right or product side of the equation. Chemicals after the reaction ends during chemical equation.

A 10.150g sample of a compound known to contain phosphorus and oxygen yields 5.717 g of oxygen. Find the empirical formula of the compound

Answers

Answer: The empirical formula is [tex]P_2O_5[/tex]

Explanation:

Mass of O = 5.717 g

Mass of P= (10.150-5.717) g = 4.433 g  

Step 1 : convert given masses into moles.

Moles of O =[tex]\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{5.717g}{16g/mole}=0.357moles[/tex]

Moles of P=[tex]\frac{\text{ given mass of P}}{\text{ molar mass of P}}= \frac{4.433g}{31g/mole}=0.143moles[/tex]  

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For O = [tex]\frac{0.357}{0.143}=2.5[/tex]  

For P =[tex]\frac{0.143}{0.143}=1[/tex]

The ratio is to be converted to whole number

Thus whole number ratio of O : P = [tex]2.5\times 2:1\times 2=5: 2[/tex]

Hence the empirical formula is [tex]P_2O_5[/tex]

1)Concave mirrors are called converging mirrors because as light falls on the mirror, it collects the light and refocuses the parallel incoming rays.

2)The image produced by a convex mirror is always virtual, and located behind the mirror. When the object is far away from the mirror the image is upright and located at the focal point.

3)When the object is located at the focal point, no image is formed. As discussed earlier in Lesson 3, light rays from the same point on the object will reflect off the mirror and neither converge nor diverge.

Gas law gave the relation between pressure, volume and temperature.

It can be expressed as:

PV = nRT.

where, P is pressure, R is gas constant and T is temperature.

Calculation of volume by using gas law.

1) Given data:

n = 1 mol

T = 25 degree C = 25 + 273 =

P = 100 kpa

Volume can be determined by the gas law.

PV = nRT

V = nRT/P

V = 1 × 8.31 × 278 / 100

V = 23.10 L

2) It is known that at STP 1 mol of any gas volume will be 22.4 L.

An important case in which sound waves change form or spread out is called refraction. This phenomenon affects the bending of a sound wave owing to changes in the wave's speed.

Refraction is the reason ocean waves near a shore parallel to the beach and why glass lenses can be used to focus light waves.

Explanation: EN increases from left to right and decreases going up to down. Due to I, Se, and Ag being on the far right of the periodic table, they have the highest EN. As you go across the periodic table, EN increases. This is why Ca would have the lowest EN. Essentially, the elements on the top right have the highest EN.
