An object has a mass of 960 g and a volume of 15cm3 what’s the density?

Answers

Explanation:

density = mass ÷ volume

mass = 960g

volume = 15³ = 15 × 15 × 15

= 3375 cm

density = 960 ÷ 3375

= 0.28 g/cm³

Answers

Answer: C, the number of atoms stay the same

Explanation:

The number of atoms remains the same before and after the reaction. This is because of the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction. In the case of methane burning, one molecule of methane (CH4) reacts with two molecules of oxygen (O2) to produce one molecule of carbon dioxide (CO2) and two molecules of water (H2O). The total number of atoms on both sides of the equation is conserved.

Sheila and Jerome are lab partners. They have the following materials at their table:

1 square of aluminum foil, 1 stirring rod, 1 beaker of water, 1 scoop of copper II chloride salt (blue color)


Step 1:Jerome adds all the salt to the water and stirs. The salt crystals disappears and the liquid solution turns a clear blue.

Step 2: Sheila tears up the aluminum foil into small pieces.

Step 3: Jerome dares her to put the foil in his beaker. They see the edges of the foil turn a rusty orange. As they stir, the beaker becomes warm to the touch and a vapor begins to rise from the surface of the beaker. Within a few minutes, the foil has disappeared and the liquid is now clear. There are orange-rust colored flakes floating in the liquid.


Q: Jerome claims that when the salt was added to the water it turned blue and the foil disappeared, these were chemical changes. He went on to explain that the chemical change was due to the fact that the atoms were speeding up. Sheila disagrees claiming that 1 is a physical change and 1 is a chemical change and Jerome’s evidence is incorrect. Who is correct, Jerome or Sheila? Write a scientific explanation (CER) to support your argument.

Just count the number number of substances, the subscript(number at the bottom) tells you how many of it there is. Then you check if there is a coefficient(number in front of all the substances) and if there is a number you multiply you previous answer by it. The coefficient tells you how many molecules there is. Your final answer is the number of atoms!
