Yes, this is a balanced chemical equation, and it obeys the Law of Conservation of Mass.
A balanced chemical equation obeys the Law of Conservation of Mass if there are the <em>same numbers of each type of atom on each side of the reaction arro</em>w.
2H₂ + O₂ ⟶ 2H₂O
Let’s check the numbers.
<u>Atom</u> <u>On the left</u> <u>On the right</u><u>
</u>
H 4 4
O 2 2
We have the same numbers of H and O atoms on each side of the reaction arrow.
The equation is<em> </em>balanced and it obeys the Law of Conservation of Mass.
True, this is why Chernobyl is still not to be lived in
Answer:
Energy transfers from the metal to the water and calorimeter until they are all at room temperature.
Explanation:
Calorimetry is the process that is used to determine the amount of heat that has been transferred in any process. In any chemical or physical process, the amount of energy is required. This energy is measured by the process of calorimetry. A calorimeter is a device that is used in this process. The heat that has been used in the process is measured and the change in the temperature is noted.
Answer:
The answer to your question is:
Explanation:
Data
V = ?
mass = 3.46 kg
Density = 1116 kg/m³
Formula
density = mass / volume
volume = mass / density
Substitution
volume = 3.46 kg / 1116 kg/m³
volume = 0.0031 m³ = 3.1 liters
In this item, we are instructed that the copper ion is to be reacted with the ion of the chlorine. The ion for copper is positively charged (cation) because it has to lose some of its electron in order to achieve stability. As the charge suggests, the number of electrons is 2.
The counterion (anion) is the chloride which can be written as Cl⁻¹. Since the charge of Cl is only -1, two of this anion should be allowed to react with Cu²⁺ so that the formed molecule is neutral. The formula is therefore CuCl₂.
<em>ANSWER: CuCl₂</em>
