Answer:

Hydrogen Gas

Explanation:

The hydrogen gas now in the test tube is flammable. So when I hold the tube over the flame, the hydrogen gas ignites and creates a popping sound. It is like a tiny bomb or fireworks.

Hope this helped! :)

If you have 5.42 x 1024 aluminum atoms, approximately how many moles is that
sattari [20]

Answer:

<h2>9.00 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{5.42 \times  {10}^{24} }{6.02 \times {10}^{23} }  \\  = 9.0033

We have the final answer as

<h3>9.00 moles</h3>

Hope this helps you

Relate what you have learned about the word quantum to the Bohr model.​
ss7ja [257]
I forgot what quantum means to be honest, the Bohr model In atomic physics, the Bohr model or Rutherford–Bohr model, presented by Niels Bohr and Ernest Rutherford in 1913, is a system consisting of a small, dense nucleus surrounded by orbiting electrons—similar to the structure of the Solar System, but with attraction provided by electrostatic forces in place of gravity. After the cubical model (1902), the plum pudding model (1904), the Saturnian model (1904), and the Rutherford model (1911) came the Rutherford–Bohr model or just Bohr model for short (1913). The improvement over the 1911 Rutherford model mainly concerned the new quantum physical interpretation.

. Calculate the number of moles in 56g of H20
svetoff [14.1K]
<h3>Answer:</h3>

3.11 moles

<h3>Explanation:</h3>

We are given 56 g of water (H₂O)

Required to calculate the number of moles of water.

  • The relationship between moles, mass and molar mass is given by;
  • Moles = Mass ÷ molar mass

in this case;

  • Mass of water = 56 g
  • Molar mass of water = 18.02 g/mol

Therefore;

Moles of water = 56 g ÷ 18.02 g/mol

                         = 3.11 moles

Therefore, moles of water in 56 g will be 3.11 moles
