We are slowly learning that even if we react, it won't change anything, it won't make people suddenly love and respespect us, it won't magically change their minds. Sometimes it's better to just let things be, let people go, don't fight for closure, don't ask for explanations, don't expect people to understand where you're coming from. We are slowly learning that life is better lived when you don't center it on what's happening around you and center it on what's happening inside you instead.

Answer: temperature, Stp

Explanation:

The calculation for standard temperature and pressure has been referred to as STP.

The mass-volume and volume-mass, has been the measurement of the concentration of the solution.

The mass-volume has been the measurement of mass of sample in the volume of solution. The volume by mass has been the measurement of the volume of solute to mass of solution.

The measurement has been performed with the standard conditions of temperature and pressure.

The standard temperature has been 273.5 K and standard pressure has been 1 atm. These temperatures and pressure has been referred to as STP.

Thus, the calculation for standard temperature and pressure has been referred to as STP.

Answer:

Yellow and Green

Explanation:

It is not blue the graph shows is isnt blue so the colors that absorbed the worse were green and yellow

Blue and red are the colors that plants can absorb the most. The pigments used for photosynthetic processes, such as chlorophyll in plant cells' chloroplasts, are what absorb particular visible-spectrum light wavelengths.

The energy of specific light wavelengths is absorbed by special pigments in chloroplasts of plant cells, resulting in a chemical chain reaction that is known as the light-dependent process of photosynthesis. The best visible light wavelengths for photosynthesis are in the blue (425–450 nm) and red (600–700 nm) ranges.

Chlorophylls do not absorb light at green and yellow wavelengths, as shown by the extremely low level of light absorption between 500 and 600 nm.

Explanation:

Solid KMnO₄ needed = 7.9 g

Given

MW KMnO₄ = 158 g/mol

500 mL(0.5 L) of a 0.1M stock solution of KMnO₄

Required

solid KMnO₄

Solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]

Input the value :

n = M x V

n = 0.1 M x 0.5 L

n = 0.05 mol

Mass KMnO₄ :

= mol x MW

= 0.05 x 158 g/mol

= 7.9 g

The solid KMnO₄ a person need to add before filling water flask will be:

"7.9 g".

According to the question,

Molecular weight of KMnO₄ = 158 g/mol

Volume of solution = 500 mL or,

                                = 0.5 L

Molarity = 0.1 M

We know the relation,

Molarity, M = [tex]\frac{n}{V}[/tex]

or,

→ n = M × V

By substituting the values,

     = 0.1 × 0.5

     = 0.05 mol

hence,

The mass of KMnO₄ will be:

= mol × Molecular weight

= 0.05 × 158

= 7.9 g

Thus the response above is appropriate.

Pseudoscience

Explanation:

Predicting the future based solely on the position of the planets is an example of pseudoscience.

Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.

Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.

Any other statement or belief that is not based on these procedures is said to be pseudoscientific.

Answer:

The number of passengers that the Embraer E170 could carry if its fuselage was made of steel  is 39 passengers

Explanation:

The given parameters of the cylinder representing the fuselage are;

The length of the cylinder, l = 30.0 meters

The width of the cylinder, w = 2.5 meters

The thickness of the cylinder, t = 2.5 mm = 0.0025 meters

The volume of the metal required to make the fuselage cylinder, V = (π·w²/4 - π·(w - 2·t)²/4) × l

Therefore, by substituting the known values, we have;

V = (π × 2.5²/4 - π×(2.5 - 2×0.0025)²/4) × 30 = 0.58845957392

The volume of the metal required to make the fuselage cylinder, V≈ 0.58846m³

The given density of steel = 7.87 g/cm³ = 7870 kg/m³

The given density of aluminum = 2.70 g/cm³ = 2,700 kg/m³

Mass = Density × Volume

The mass of the fuselage made with steel = The given density of steel × The volume of the metal required to make the fuselage cylinder

∴ The mass of the fuselage made with steel = 7870 × 0.58846 ≈ 4631.18

The mass of the fuselage made with steel ≈ 4631.18 kg

Similarly, the mass of the fuselage made with aluminum = 2,700 × 0.58846 ≈ 1588.84

The mass of the fuselage made with aluminum ≈ 1588.84 kg

The total mass the Embraer E170 could carry = The mass of the fuselage made with aluminum + The mass of the 78 passengers

The average mass of each passenger = 79 kg

∴ The total mass the Embraer E170 could carry ≈ 1588.84 + 78 × 79 = 7750.84

The total mass the Embraer E170 could carry ≈ 7750.84 kg

The extra mass the Embraer E170 could carry when made of steel = (The total mass the Embraer E170 can carry) - (The mass of the fuselage made with steel)

∴ The extra mass the Embraer E170 could carry when made of steel = 7750.84 - 4631.18 = 3119.36

The extra mass the Embraer E170 could carry when made of steel ≈ 3119.36 kg

The number of passengers the Embraer E170 could carry when made of steel  = (The extra mass the Embraer E170 could carry when made of steel)/(The average mass of one passenger)

∴ The number of passengers the Embraer E170 could carry if its fuselage was made of steel  = 3119.36 kg/(79 kg/passenger) ≈ 39.489 passengers

The number of passengers that the Embraer E170 could carry if its fuselage was made of steel  ≈ 39 passengers (we round down when counting people which are whole quantities)

Answer:

C6H10Cl2

Explanation:

Convert mass % to mass

100g of the compound contains from each elements: 46,3g Cl; 47,05g C and 6,63g H

Molar mass

Cl = 35.5 g/mol

C = 12 g/mol

H = 1 g/mol

Find the number of moles:

Chlorine: 46.4g /35.5g/mol = 1,3 moles

Carbon: 47,05g/12 g/mol = 3,92 moles

hydrogen: 6,63g/1g/mol = 6,63 moles

Molar fraction:

Cl = 1,30/ 1,30 = 1

C = 3,92/ 1,30 = 3,01

H = 6,63/ 1.30 = 5,01

C3H5Cl = 76,5 g/ mol x 2  = 153 g/ mol

So multiply the molecular formula by two = C6H10Cl2

Answer:

Substance X has a smaller mass

Explanation:

The relationship between the mass of the two samples is that the mass of X is smaller compared to the mass of Y.

 The specific heat capacity is given as:

         C  = [tex]\frac{H}{m x change in temperature}[/tex]

We can see that the higher the specific heat capacity the lesser the mass or simply put, the specific heat capacity of a body is inversely related to its mass.

If the amount of heat is constant i.e the same and the specific heat capacity of X is twice that of Y, then substance X has a smaller mass
