Answer:
New volume, V2 = 15mL
Explanation:
Given the following data;
Initial volume, V1 = 30mL
Initial pressure, P1 = 4atm
New pressure, P2 = 8atm
To find the new volume V2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Substituting into the equation, we have;
V2 = 15mL
<em>Therefore, the new volume is 15 mL. </em>
When forming an ion, this sodium atom will lose 1 electron, as it is the easiest way to form a full shell, as opposed to gaining 7 electrons.
Answer:
To express the efficiency of a reaction, you can calculate the percent yield using this formula: %yield = (actual yield/theoretical yield) x 100. A percent yield of 90% means the reaction was 90% efficient, and 10% of the materials were wasted (they failed to react, or their products were not captured).
Explanation:
The part with the highest frequency and shortest wavelength, you mean? That would be gamma rays.
Answer:
2 chlorine atoms.
Explanation:
H₂ + Cl₂ → 2HCl
The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction.
If 2 molecules of Hydrogen and 2 molecules of Chlorine is present in the reactants, the same no. of atoms should also be present in the product.
∴ the no. of chlorine atoms in the product is 2.
