1 answer:
Anton [14]3 years ago
7 0

Answer:

Electrons

Explanation:

In an atom there would be three subatomic particles: Neutrons, electrons, protons. The smallest and lightest in terms of mass is electrons. This is because the nucleus is comprised of the protons and the neutrons, these have a greater mass than electrons as electrons has very little mass that can considered to be 0.

What volume of 15.7 M H2SO4 is required to prepare 12.0 L of 0.156 M sulfuric acid?
kirza4 [7]

The volume of 15.7 M H2SO4 is required to prepare 12.0 L of 0.156 M sulfuric acid is 0.12 L

<h3>Data obtained from the question</h3>

From the question given above, the following data were obtained:

  • Molarity of stock solution (M₁) = 15.7 M
  • Volume of diluted solution (V₂) = 12 L
  • Molarity of diluted solution (M₂) = 0.156 M
  • Volume of stock solution needed (V₁) = ?

<h3>How to determine the volume of the stock solution needed</h3>

The volume of the stock solution needed can be obtained by using the dilution formula as shown below:

M₁V₁ = M₂V₂

15.7 × V₁ = 0.156 × 12

15.7 × V₁ = 1.872

Divide both side by 15.7

V₁ = 1.872 / 15.7

V₁ = 0.12 L

Thus, the volume of the stock solution needed to prepare the solution is 0.12 L

Write einstein's equation that explains the energy from nuclear reactions. _________ use the caret symbol (^) to show an exponen
Katen [24]
I would say it should be Einstein's famous equation of e=mc^2 which means energy =mass x the speed of light squared. With this equation Einstein showed that energy comes from a mass travelling at the speed of light squared which is a fundamental equation to explain physical phenomena.

(a) Red light has a wavelength of roughly 700 nm. What is the wavelength in m? ball park 10.10' (b) What is the wavelength of re
joja [24]

Explanation:

1)

a) Wavelength of red light = 700 nm

1 nanometer = 10^{-9} meter

Wavelength of red light in meter will be:

=700 nm=700\times 10^{-9} m=7.00\times 10^{-7} m

b) Wavelength of red light = 7.00\times 10^{-7} m

1 meter  = 39.3701 inches

Wavelength of red light in inches will be:

7.00\times 10^{-7} m=7.00\times 10^{-7}\times 39.3701 inches

=2.7559\times 10^{-5} inches

2)

Value of distance given = 90.123 km

1 km = 3280.84 feet

90.123 km=90.123 \times 3280.84 feet=295,679.1433 feet

1 foot = 0.1515152 chain

295,679.1433 feet=295,679.1433\times 0.1515152 chain

=44,799.88453 feet\approx 4.48\times 10^4 chains

Value of distance in chains:

90.123 km=4.48\times 10^4 chains
