the overall numbers of atoms only
both the overall types and numbers of atoms
neither the overall types or numbers of atoms
Both the overall types and numbers of atoms stay the same during chemical reactions.
Answer:
1) 6(1/2)
2) 8(4/5)
Explanation:
1) 7 - 1/2 = 7/1 - 1/2 = 14/2 - 1/2 = 13/2 = 6(1/2)
2) 11(2/5) - 2(3/5) = 57/5 - 13/5 = 44/5 = 8(4/5)
The value of the concentration of A is 0.529.
Since the rate constant has units of s⁻¹, we can tell that the order of the reaction is 1.
Here, is the initial concentration, t is the time, A is the final concentration, and k is the rate constant.
Substitute the given value values in the equation as follows,
The concentration of A in (M) is 0.529.

Answer:
Explanation:
Since the rate constant has units of s⁻¹, you can tell that the order of the reaction is 1.
Hence, the rate law is:
Solving that differential equation yields to the well known equation for the rates of a first order chemical reaction:
You know [A]₀, k, and t, thus you can calculate [A].
-atoms splitting to make heat which in turn turns a generator to make electricity
-car battery turning a car on
-food making you run
Answer:
A car battery turning a car on.
bar as she swings through the air. After he stops pushing her, she slows down
and eventually stops. This example shows that:
A. energy is converted between forms with complete efficiency.
B. energy is created as Sally's dad begins to push her.
C. energy is destroyed by friction and vibration.
D. energy is transferred to friction and vibration as it is converted between different forms.
According to law of conservation of energy, the given example shows that energy is transferred to friction and vibration as it is converted between different forms as it can neither be created nor destroyed.
According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a process .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.
