<h2>Answer with Explanation </h2>

An action of enhancing the temperature would be most feasible to improve the rate of reaction as the kinetic energy increments which generates the particles to collide with each other quicker. The rate of reaction duplicates for every 10 degree Celsius rise in temperature which causes the particles to have more collisions vigorously at an intense rate. The frequency of collisions also increases giving more speed to the rate of reaction which reaches energies equal to or greater than activation energy.

Molar mass = 144.2 g/mol.

<h3>Calculate Molar mass.</h3>

Formula to solve this: ΔT = Kf . m

ΔT → Freezing point of pure solvent - Freezing point of solution

0°C - (-1.94°C) = 1.86 °C/m . m

1.94°C / 1.86 m/°C = m →  1.04 m

1.04 are the moles of solute in 1kg of solvent → molality (mol/kg)

Let's convert the mass of our solvent in kg to determine the moles.

80 g . 1kg / 1000 g = 0.08 kg

Molality . kg of solvent → Solute moles

1.04 mol/kg . 0.080 kg = 0.0832 moles

These are the moles of 12 g of solute. To find the molar mass → g/mol

12 g / 0.0832 mol = 144.2 g/mol

What element in period 4 has the lowest ionization energy? noble gas, alkali metal, halogen or alkaline earth metal?
Gwar [14]

Answer:

alkali metal

Explanation:

The alkali metals in period 4 will have the lowest ionization energy of the elements in the period.

Across a period ionization energy increases progressively from left to right due to decreasing atomic radii caused by the increasing nuclear charge which is not compensated for by successive electronic shells.

  • Ionization energy is the energy needed to remove the most loosely bound electrons of an atom in the gas phase in the ground state.
  • The measure of the readiness of an atom to lose an electron is the ionization energy.

Down a group, it decreases.

Use the formula q=m×Cp×delta T

m=1.500 kg=1,500 g
Co=2.52 J/g·k
delta T=0.985k

q=(1,500g)(2.52 J/g·k)(0.985k)

=3,723.3 J=3.72


I JUST FINISHED THIS QUESTION AND IT SAID THAT THE ANSWER WAS -3.72 kJ SO PUT THAT DOWN AS YOUR ANSWER....I'm not sure why the answer is negative, but this is the most work I can show. If any one knows, why this answer is negative, please advise. Thank you. I hope that this helps :)
