Answers

Answer:

In the backrest use materials where it is easy to clean and where they do not absorb fluids, in this way it would be cooler, such as an ecological leather simulator.

And in the armrest as well, but in both areas we must not rule out that if or if it should have even a minimum of padded surface so that the patient or the person who spends most of the day in the wheelchair does not suffer from joint pain.

Some wheelchair factories also implement modern chairs where they are made of stainless steel structures lined with padded material with perforated fabrics that allow breathing and aeration of body areas that have contact with the fabric.

what happens when light is not spread out

Answers

Answer:

Spreading out a wave over a larger area just causes the wave strength to weaken, but does not cause gaps to form. Therefore, if you look at photons as waves, spatial gaps never form in light as it travels through free space, no matter how dim it gets.Spreading out a wave over a larger area just causes the wave strength to weaken, but does not cause gaps to form.

3.

Which state of matter has the most movement of its particles?

Solid

Liquid

Gas

Answers

1. Solids. The particles in a solid are tightly packed together and can only vibrate from their fixed positions.
2. Energy. Adding in energy makes the particles of a substance vibrate faster, breaking the forces of attraction between them and removing energy makes the particles vibrate slower and forces of attraction forms between the particles.
3. Gas. The forces of attraction between the particles of a gas are very weak. The particles randomly and quickly move around in all directions.

Solids are the most organized state of matter. States of matter change when energy is added or removed. Gas is the state of matter has the most movement of its particles.

What are the states of matter?

The states of matter are the different forms of the matter in which it can exist. They are solids, liquids and gases. Solids are the states of matter in which molecules are very near to each other. They have fixed shape and volume. Liquids is the states of matter in which molecules are a little far from each other. They have different shape and fixed volume. Gas is the states of matter in which molecules are a very far from each other. They have different shape and different volume.

There are two more states of matter which are called as Plasma, Bose Einstein Condensate.

Plasma have highest energy and Bose Einstein Condensate have lowest energy.

Therefore, Solids are the most organized state of matter. States of matter change when energy is added or removed. Gas is the state of matter has the most movement of its particles.

A 0.050L solution of Ba(OH)2 is neutralized by 0.072L of a 0.55 M HNO3 solution. What is the concentration of the Ba(OH)2 solution?

Answers

Answer:

0.396M

Explanation:

Step 1:

The balanced equation for the reaction. This is given below:

2HNO3 + Ba(OH)2 —> Ba(NO3)2 + 2H2O

From the balanced equation above,

The mole ratio of the acid (nA) = 2

The mole ratio of the base (nB) = 1

Step 2:

Data obtained from the question. This include the following:

Volume of base (Vb) = 0.05L

Concentration of base (Cb) =..?

Volume of acid (Va) = 0.072L

Concentration of acid = 0.55 M

Step 3:

Determination of the concentration of the base, Ba(OH)2.

The concentration of the base, Ba(OH)2 can be obtained as follow:

Cava /CbVb = nA/nB

0.55 x 0.072 / Cb x 0.05 = 2/1

Cross multiply to express in linear form

Cb x 0.05 x 2 = 0.55 x 0.072

Divide both side by 0.05 x 2

Cb = (0.55 x 0.072) / (0.05 x 2)

Cb = 0.396M

Therefore, the concentration of the base, Ba(OH)2 is 0.396M

Analysis: The limiting reactant(s) appeared to be
because

Answers

there is nothing with which it can react

Explanation:

The limiting reactant(s) prevents a reaction from continuing because there is none left.

Why do limiting reactants occur?

Identification of the limiting reactant makes it possible to calculate the theoretical yield of a reaction. The reason there is a limiting reactant is that elements and compounds react according to the mole ratio between them in a balanced chemical equation.

How do you get the limiting reactant?

The reactant that is consumed first and limits the amount of product(s) that can be obtained is the limiting reactant. To identify the limiting reactant, calculate the number of moles of each reactant present and compare this ratio to the mole ratio of the reactants in the balanced chemical equation.

How many moles of H2 are needed to produce 18 moles NH3 in the reaction below?
N2 + 3 H2 —> 2 NH3

Answers

Answer:

27 moles of H₂

Explanation:

Equation of reaction:

N₂ + 3H₂ → 2NH₃

From the equation of reaction,

3 moles of H₂ is required to produce 2 moles of NH₃

3 moles H₂ = 2 moles of NH₃

X moles of H₂ = 18 moles of NH₃

X = (3 * 18) / 2

X = 27 moles of H₂

27 moles of H₂ is required to produce 18 moles of NH₃

What is the molariity of a 50.0 mL aqueous solution containing 10.0 grams of copper (II) sulfate, CuSO4?

Answers

Answer:

The molarity is 1.26 [tex]\frac{ moles}{L}[/tex]

Explanation:

Molarity is a unit of concentration that is based on the volume of a solution and represents the number of moles of solutes contained in a liter. The molarity of a solution is calculated by dividing the moles of the solute by the liters of the solution and is expressed in units (moles / liter).

[tex]Molarity=\frac{number of moles of solute}{Volume}[/tex]

You must calculate the number of moles of CuSO₄. So, being:

Cu: 63.54 g/moleS: 32 g/moleO: 16 g/mole

the molar mass of CuSO₄ is

CuSO₄=63.54 g/mole + 32 g/mole + 4* 16 g/mole= 159.54 g/mole

Then it is possible to apply the following rule of three: if 159.54 g of CuSO₄ are present in 1 mole, 10 g in how many moles are they?

[tex]moles=\frac{10 g*1 mole}{159.54 g}[/tex]

moles= 0.063 moles

Then:

number of moles of solute= 0.063 molesVolume= 50 mL= 0.05 L (Being 1L=1000 mL)

Replacing in the definition of molarity:

[tex]Molarity=\frac{0.063 moles}{0.05 L}[/tex]

Molarity= 1.26 [tex]\frac{ moles}{L}[/tex]

The molarity is 1.26 [tex]\frac{ moles}{L}[/tex]

metallic iron?
4Fe(s) + 302(g) → 2Fe2O3 (9)
LO2​

Answers

Answer:

Volume of oxygen gas is 78.47L

Explanation:

Data;

Temperature (T) = 20°C = (20 + 273.15)K = 293.15K

Pressure (P) = 0.919atm

Mass (m) = 5g

Volume (v) = ?

Equation of reaction;

4Fe + 3O₂ → 2Fe₂O₃

From the equation of reaction, the number of moles of oxygen is 3.

To find the volume of oxygen produced, we'll have to use ideal gas equation

PV = nRT

P = pressure

V = volume

n = number of moles

R = ideal gas constant = 0.082J/mol.K

T = temperature of the ideal gas

PV = nRT

V = nRT/ P

V = (3 × 0.082 × 293.15) / 0.919

V = 72.1149 / 0.919

V = 78.47L

Volume of the gas is 78.47L

Explanation:

From the above question, Leon gave us two variables, X and Y.

The human induced changes were divided into two.

1. Results from introducing harmful substances into the environment

Introducing harmful substances into the environment is also called pollution. And we can represent this as X which is the first variable.

2. Results from natural areas being cleared and replaced by human development.

This description given in number two above whereby land areas are been cleared and replaced by human development has a negative effects on the environment because the vegetation which includes the trees are been cut down and living organisms(animals) will go extinct gradually. This act affect the balance of the ecosystem and it can be referred to as the destruction of the habitat of living organisms
