Answer:
Hi, the question is incomplete. However, the question is about the calculation of volume of a product when the volume of one of the reactants is provided.
9.587 cm^3
Explanation:
The balanced equation for the chemical reaction is shown below:
⇒
In the chemical reaction above, 2 moles of water produced 4 moles of hydrogen fluoride. If 4.8 cm^3 of water were consumed, we can calculated the volume of hydrogen fluoride that would be produced as follow:
Using STP, 1 mole of gas has a volume of 22.4 L
Thus, 4.8 cm^3 = 0.0048 L is equivalent to 2.14*10^-4
since 2 moles of water produced 4 moles of hydrogen fluoride, therefore, 2.14*10^-4 would produced 2*2.14*10^-4 = 4.28*10^-4 moles
we can convert the moles to L by multiplying with 22.4
volume of hydrogen fluoride = 4.28*10^-4 * 22.4 = 0.009587 L = 9.587 cm^3
Answer:
0.43×10²³ atoms
Explanation:
Given data:
Mass of LiBrO₂ = 4.28 g
Number of atoms of oxygen = ?
Solution:
Number of moles = mass/molar mass
Number of moles = 4.28 g/ 118.84 g/mol
Number of moles = 0.036 mol
We can see 1 mole of LiBrO₂ contain 2 mole of oxygen atm.
0.036 mol × 2 = 0.072 mol
1 mole contain 6.022×10²³ atoms
0.072 mol × 6.022×10²³ atoms / 1mol
0.43×10²³ atoms
The answer is D "Volatility"
have a great day!!!
Moving in a direction is called having a "velocity". A velocity is just having a speed, but only in one direction. Because of a thing called "Newton's First Law", in order to change the speed or direction of an object, it must be accelerated, which is a fancy way of saying it's velocity must change with respect to time, meaning that for every second it travels while be accelerated, its velocity will change by this much, either in speed or direction or both. Due to "Newton's Second Law", and acceleration is gained by applying a force. Using the equation "F = ma" where F is force applied, m is mass of the object, and a is the acceleration of the object. This means that it is harder to move things with more mass.
Specifically relating to change in direction, force is also a thing which has a direction. A force can be any size, and also have any direction. When a force is applied in a certain direction, the acceleration of the object will be in the same direction of the force.
Transfer and gain of kinetic energy by the water molecules takes place as water cycles from the bottom of the pot toward the top.
<h3>What is thermal energy?</h3>
Thermal energy is a another word to express the heat energy.
When we boil a water over a gas burner then due to convention, heat energy can be transfer to the bottom water molecules in the form of thermal energy. After gaining the thermal energy movement of water molecules increases as a result of the increase of the kinetic energy.
Hence, option (1), (2) & (4) are correct i.e. transfer and gain of kinetic energy by the water molecules is done.
