Answer:

If More solute is added and it does not dissolve,then the original solution was saturated. if the added solute dissolves,then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of the container must be saturated.

These are two questions and two answers

Question 1.

Answer:

7.33 × 10 ⁻³ c

Explanation:

1) Data:

a) m = 9.11 × 10⁻³¹ kg

b) λ = 3.31 × 10⁻¹⁰ m

c) c = 3.00 10⁸ m/s

d) s = ?

2) Formula:

The wavelength (λ), the speed (s), and the mass (m) of the particles are reltated by the Einstein-Planck's equation:

λ = h / (m.s)

h is Planck's constant: h= 6.626×10⁻³⁴J.s

3) Solution:

Solve for s:

s = h / (m.λ)

Substitute:

s = 6.626×10⁻³⁴J.s / ( 9.11 × 10⁻³¹ kg × 3.31 × 10⁻¹⁰ m) = 2.20 × 10 ⁶ m/s

To express the speed relative to the speed of light, divide by c = 3.00 10⁸ m/s

s = 2.20 × 10 ⁶ m/s / 3.00 10⁸ m/s = 7.33 × 10 ⁻³

Answer: s = 7.33 × 10 ⁻³ c

Question 2.

Answer:

2.06 × 10 ⁻³⁴ m.

Explanation:

1) Data:

a) m = 45.9 g (0.0459 kg)

b) s = 70.0 m/s

b) λ = ?

2) Formula:

Macroscopic matter follows the same Einstein-Planck's equation, but the wavelength is so small that cannot be detected:

λ = h / (m.s)

h is Planck's constant: h= 6.626×10⁻³⁴J.s

3) Solution:

λ = h / (m.s)

Substitute:

λ = 6.626×10⁻³⁴J.s / ( 0.0459 kg × 70.0 m/s) = 2.06 × 10 ⁻³⁴ m

As you see, that is tiny number and explains why the wave nature of the golf ball is undetectable.

Answer: 2.06 × 10 ⁻³⁴ m.

chlorine has 7 outer energy level electrons and argon has 8. what is the difference in the reactivity of these two elements?

Lunna [17]

Chlorine is more reactive than argon, because argon is not reactive at all. Chlorine only has to gain 1 valence electron

What is the temperature difference if 300 cal are used to warm water

PIT_PIT [208]

Answer:

The temperature difference is $\frac{300}{m} Kkg^{-1}$

Explanation:

The formula that is to used is :

Δ $Q=ms$ Δ $T$

where ,

Δ $Q$ is the heat supplied in calories = 300cal
$m$ is the mass of water taken = m (assumed)
Δ $T$ is the change in temperature
$s$ is the specific heat of water = $1calK^{-1}Kg^{-1}$

ΔT :

$\frac{300}{m*1} \\=\frac{300}{m} Kkg^{-1}$

Calculate the rcf (recipe conversion factor) for a new yield of 80 oz. (5 lbs) blueberry muffin batter. the original yield of th

SCORPION-xisa [38]

The rcf (recipe conversion factor)= 0.6

<h3>What is the rcf (recipe conversion factor)?</h3>

The conversion factor approach is the most typical technique for modifying recipes.
Finding a conversion factor and multiplying the ingredients in the original recipe by that factor are the only two steps needed to do this.
Remember that the conversion factor will be larger than 1 if you are raising your amounts to be sure you are finding it correctly.
The factor will be less than 1 if your amounts are being decreased. Use the conversion factor approach if you come across a recipe that is written in a standard format.

The production of phenolic monomers from lignin is effective and selective when done using reductive catalytic fractionation (RCF).

How this is calculated?

Conversion Factor = New Yield ÷ Old Yield

=80/134

=0.5970

=0.6(rounded to nearest tenth)
