Which 2025 movie reboot features Rachel Zegler and Gal Gadot in the classic Disney tale?
(Hint: it’s a live-action version of a well-known fairy tale.)
Snow White
Oxygen: atomic number 8, mass number 16. How many protons, neutrons and electrons?
All 3 are 8!
State how an ion is formed
Ions are formed when an atom loses or gains an electron
How many moles are in 180g of water?
10 moles
Define Electrolysis.
Electrolysis is the decomposition of ionic compounds using electricity.
Name the global hit song by Alex Warren that spent 12 consecutive weeks at No. 1 on the UK Official Singles Chart in the first half of 2025.

Describe 2 differences between Mendeleev's Periodic Table and our current one.
Elements arranged in order of increasing mass, Left gaps for undiscovered elements
Describe the bonding found in NaCl.
Na loses an electron to form positive ion, Cl gains electron to form negative ion. Electrostatic attraction between oppositely charged electrons
0.2 mol/dm3 of NaCl are dissolved in 250cm3 of water. What is it's concentration?
0.8 moldm3 -> 250/1000 = 0.25 dm3 ; 0.2/0.25
Write a balanced symbol equation to show the reaction between Magnesium Carbonate and Hydrochloric Acid.
MgCO3 + 2HCl --> MgCl2 + H2O + CO2
Which song released on May 30, 2025, by Tate McRae, reached No. 1 on Billboard’s Hot Dance/Pop Songs and was featured on the F1 movie soundtrack?
Midnight Circuit
Element X has electron configuration 2.8.8.1.
Explain which period and group is this element in?
Group 1 - 1 electron in outer shell. Period 4 - 4 electron shells
Explain why sodium conducts electricity.
Contains delocalised electrons which can carry charge
N2 + 3H2 --> 2NH3
Calculate the mass of Hydrogen (H2) required to react with 140 g of N2.
30g
Describe how to carry out a titration between an acid and an alkali. (Need to include names of equipment)
Any 3 points of the following:
Use a pipette to measure a fixed volume of alkali (e.g. sodium hydroxide) into a conical flask
Add a few drops of indicator (e.g. phenolphthalein or methyl orange)
Fill a burette with acid of known concentration (e.g. HCl)
Slowly add acid to alkali while swirling the flask
Stop when the indicator changes colour (end point), and record the volume
Repeat for concordant results (within 0.1 cm³)
What animated sequel became the highest-grossing film of 2024?
Inside Out 2
Explain why Group 1 elements become more reactive down the group. (3 points!)
1. Atoms get bigger/have more shells
2. Outer electron is farther from the nucleus
3. Easier to lose/less attraction to nucleus
Explain why Potassium Chloride has a high melting point while water does not.
Potassium Chloride is ionically bonded, so it has a strong force of attraction between ions which requires a lot of energy to overcome. Water has weak intermolecular forces so does not require as much energy to overcome. MUST HAVE REASON FOR BOTH.
22.5 cm3 of NaOH reacted with 25.0 cm3 of 0.1 mol/dm3 HCl. Calculate the concentration of NaOH.
HINT: Reacting Ratio is 1:1!
0.111 mol/dm3
Explain, in terms of ions and electrons, what happens during the electrolysis of molten lead bromide. Include half equations.
Lead bromide contains Pb²⁺ and Br⁻ ions
During electrolysis:
Pb²⁺ ions move to the cathode and gain electrons (reduction)
Br⁻ ions move to the anode and lose electrons (oxidation)
Pb²⁺ + 2e⁻ → Pb (at cathode)
2Br⁻ → Br₂ + 2e⁻ (at anode
Name the two main actors that starred in the now highest grossing R-Rated movie of all time?
HINT: It's a super hero movie!
