Answer:
<h3>The answer is 12.5 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 2.5 × 5
We have the final answer as
<h3>12.5 g</h3>
Hope this helps you
Due to lava which heats water where water vapour is comes
"X" in the reaction above is acetic acid with a chemical formula CH3COOH. The chemical reaction would be NaOH + CH3COOH = NaCH3COO + H2O. This is a neutralization reaction in which it produces a salt and water. The salt produced is called sodium acetate.
Answer: The values can be converted from one unit to other unit still keeping the meaning same. We use the number 273 (273.15 exactly) to convert from Celsius to Kelvin and vice versa. . ... Kelvin temperature scale: In Kelvin temperature scale, the zero point is shifted from freezing point of water to the absolute zero point.
Explanation:
Basically the answer
Answer:
The correct answer is - They gently shake the pan causing the marbles to move back and forth.
Explanation:
When water is heated the molecules present in its liquid state start to move and vibrate faster and allows the water to expand and increase in volume. If the heat is continuously applied to the water its molecules move even faster and escape in the form of molecules of vapor to the atmosphere.
To exhibit this phenomenon by the marble and pan, Richard and Brooke should gently shake the pan causing the marbles to move back and forth which shows faster vibration and movement of molecules.
