A cause nuclear fission creates elements that are electrically charged so that way it kinda breaks the law of physics as it kinda makes energy but not entirely so it doesn’t exactly break the laws but still it’s weird. Anyways it’s A as those elements can generate energy.

Hope that helps.

Determine the number of molecules in 0.0500 mole of boron tribromide<br> (show work)
OleMash [197]

Answer:

There are 0.5 moles

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number  of particles.

To calculate the moles, we use the equation:

Thus there are 0.5 moles

Which of the following most completely describes an object's motion?
Gre4nikov [31]
Hello!

This is a difficultly easy question, mostly because it seems like all of the answers would be right, but if I had to choose one, I would say (D) because this option gives the most detail.

Option A only tells us how fast a car was moving
Option B only tells us the rate the water falls and how fast it is going
Option C only tells how far and not the speed or destination
Option D is correct, it tells us the speed/rate, the destination, and what is moving


Therefore, Option (D) is correct


If this helps, please mark brainliest, have a great day!!

What is the chemical equation of ccl4, please explain thank you! :-D
Gekata [30.6K]
It could be
C + 2Cl2 ➡️ CCl4
I decided this because I believe this is the only way you could make this a balanced equation. To be a balanced equation Both sides of the equation has the same number of atoms for each element. Carbon has 1 atom and chlorine has 4.

Liquid methylene bromide has a density of 2.50 g/mL. A barometer is constructed using methylene bromide instead of mercury. If t
vova2212 [387]

Answer:

393 cm

Explanation:

Step 1: Given and required data

  • Density of liquid methylene bromide (ρ): 2.50 g/mL (2.50 g/cm³)
  • Earth's gravity (g): 9.81 m/s²
  • Atmospheric pressure (P): 0.950 atm

Step 2: Convert 0.950 atm to Pa (N/m²)

We will use the conversion factor 1 atm = 101325 Pa.

0.950 atm × 101325 Pa/1 atm = 9.63 × 10⁴ Pa

Step 3: Convert 2.50 g/cm³ to kg/m³

We will use the conversion factors:

  • 1 kg = 10³ g
  • 1 m³ = 10⁶ cm³

\frac{2.50g}{cm^{3} } \times \frac{1kg}{10^{3}g } \times \frac{10^{6}cm^{3}  }{1m^{3} } =  2.50 \times 10^{3} kg/m^{3}

Step 4: Calculate the height (h) of the liquid column

We will use the following expression.

P = ρ × g × h

h = P / ρ × g

h = 9.63 × 10⁴ Pa / (2.50 × 10³ kg/m³) × 9.81 m/s²

h = 3.93 m = 393 cm
