Answer:
Density of the object is 8759.494 grams/L
Explanation:
As we know density of an object is mass of the object divided by its volume
Given
Volume of the object is equal to the change in volume of water with in the cylinder when the object was immersed in water.
Hence, volume of object is equal to
mL
Mass of the object is grams
Density
grams/L
Density of the object is 8759.494 grams/L
<u>Answer:</u> The correct answer is temperature of the gas.
<u>Explanation:</u>
Average kinetic energy of the particles is defined as the average of the kinetic energies of all the particles in a gas molecule. The equation used to calculate the average kinetic energy of a gas is given by:
where,
K = kinetic energy of the gas
R = gas constant
T = temperature of the gas
= Avogadro's number
From the above equation, kinetic energy is directly related to the temperature of the gas molecule. As, the temperature of the gas increases, kinetic energy also increases and vice-versa.
Hence, the correct answer is temperature of the gas.
Answer:
2 KF ₍s₎ → F₂ ₍g₎ + 2 K ₍s₎
Explanation:
Chemical Formula of Potassium Fluoride = KF
Chemical Formula of Fluorine Gas = F₂
Chemical Formula of Solid Potassium = K
Step 1: Write the unbalance chemical equation,
KF → F₂ + K
Step 2: Balance Fluorine Atoms;
As there is one fluorine atom on left hand side and two fluorine atoms on right hand site therefore, to balance them multiply KF on left hand side by 2 i.e.
2 KF → F₂ + K
Step 3: Balance Potassium Atoms;
As there are two potassium atoms on left hand side and one potassium atom on right hand site therefore, to balance them multiply K on right hand side by 2 i.e.
2 KF → F₂ + 2 K
Step 4: Assign Physical states as,
2 KF ₍s₎ → F₂ ₍g₎ + 2 K ₍s₎
