100
This is what happens to the first ionisation energy as you move across the periodic table
What is increase?
100
In paper chromatography, this is also known as the solvent
What is the mobile phase?
100
The number of moles are in 2.0 g of hydrogen gas (H₂)
What is 1 mol?
100
This equation relates heat, mass, temperature change, and specific heat capacity.
What is q = mcΔT?
200
This element has the highest electronegativity out of all the elements on the periodic table
What is fluorine?
200
This is the unknown element's identity
What is strontium
200
This formula is used to calculate the number of moles from mass.
What is n = m / M?
200
Calculate the heat absorbed when 100 g of water increases by 5°C (c = 4.18 J/g°C).
What is 2090 J?
300
This atomic property decreases down a group due to increased electron shell levels.
What is the atomic/ionic radius?
300
The reason that the flame changes colour when different metals are heated.
What is excited electrons?
300
The number of molecules in 0.5 mol of CO₂
What is 3.01 × 10²³ molecules?
300
If 2000 J of energy raises 50 g of a substance by 10°C, calculate its specific heat capacity.
What is 4.0 J/g°C?
400
This property increases as you move across a period from left to right due to increasing nuclear charge.
What is electronegativity?
400
In AES and AAS, this is the reason why the spectra emit/absorb different colour lights
What is emitting/absorbing different specific wavelengths?
400
In the reaction 2H₂ + O₂ → 2H₂O, if you have 4 mol H₂ and 1 mol O₂, this is the limiting reactant.
What is oxygen (O₂)?
400
The explanation why water has a high specific heat capacity compared to most substances.
What is strong hydrogen bonding requires more energy to increase temperature?
500
These are the 2 reason why electronegativity changes, which also thereby causes polar bonds
What is:
Different distance from the central positive nucleus
More protons in the central nucleus for electrons in the same shell/orbital
500
This is the relative atomic mass (RAM) for this element
What is 63.62?
500
DAILY DOUBLE
A student reacts 10.0 g of CaCO₃ with 100.0 mL of 1.50 M HCl according to the equation:
CaCO₃(s)+2HCl(aq)→CaCl₂(aq)+CO₂(g)+H₂O(l)
This is the mass of CO₂ produced
What is 3.30grams?
500
A student burns 0.1 mols of ethanol (C₂H₅OH), heating 200.0 g of water from 25.0°C to 35.0°C.
(The specific heat capacity of water is 4.18 J g⁻¹ °C⁻¹)
This is the molar enthalpy of ethanol
What is 83600 J/mol?
