Answer:
A is your answer.
Explanation:
This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.

Answer:
The pressure of the gas is:
<u>Doubled</u>
<u></u>
Explanation:
Byole's Law = Pressure of fixed amount of gas is inversely proportional to Volume at constant temperature.
PV = k = constant
P1V1 = P2V2
<u>Charle's Law: </u> The volume of ideal gas at fixed pressure is directly proportional to Pressure.
V/T = constant
V1/T1 = V2/T2
On combinig the charles and byole's law , we get:

Now , According to question :
V2 = V1
T2 = 2(T1)
We have to find the relation between the pressure :
insert the value in the equation


V1 and V1 & T1 and T1 cancels each other,
So we get
P2 = 2 P1
So the new pressure is double of the original pressure
Answer:
Two (2) types of ions
Explanation:
Metal ions (cations) and negatively charged ions (anions) of either chloride, carbonate, sulphides or hydroxides are present during the selective precipitation.
Majorly, the process determines the metal ions present by initiating precipitation as certain conditions.
I hope this was helpful.
When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.
