Answer:

Sand

Explanation:

If you get salt or sugar in your water, you have to legit desalinate it to get the water and item out. You need to evaporate the water by increasing temperature and then lower temperature to separate the substances.

If you have alcohol, you need to distill it by trapping it and stuff.

With sand, the molecules are much larger which lets you separate the substances easily.

For example, on a beach, you can slap a handful of sand in your pail, but the sand sinks to the bottom right? You can just pour out the water.

Answer:  Thermal energy is the kinetic energy of particles and heat is the term used to describe how this energy may flow to other systems, such as in a radiator.

Explanation:  Molecules have a level of kinetic energy that can be measured by temperature.  Higher temperatures result in more rapid and frequent collisons of particles in motion.  Heat is the term used to measure the quantity of vibration energy in a given system.  The SI unit for heat energy is the Joule.  The water molecules in a pot of boiling water have a kinetic energy sufficient for them to break away from other water molecules and become gaseous (boiling point).  The heat energy in 1 liter of water at 95C can be calculated in terms of Joules/liter, based on the specific heat of water (e.g., in units of J/gC).  This heat can flow to other systems.  A home boiler heater unit heats water tha can be pumped around the house ehre it will flow from radiators into thje surrounding air.

Heat is the word used to explain how this energy may transfer to other systems, such as in a radiator, and thermal energy is the kinetic energy of particles.

By virtue of its temperature, a system in a condition of thermodynamic equilibrium has thermal energy or internal energy. Unlike the energy of systems that are not in a state of thermodynamic equilibrium, thermal energy cannot be transformed into meaningful work as quickly.

For instance, the same fluid or solid in a thermodynamic equilibrium state with the same energy (as thermal energy) cannot do work unless it is combined with another substance at a different temperature, as in a heat engine. However, the same fluid or solid in a moving state with the same energy (as mechanical energy) can be converted to work in some mechanical device, such as a windmill or a waterwheel.

Therefore, heat is the word used to explain how this energy may transfer to other systems, such as in a radiator, and thermal energy is the kinetic energy of particles.

Answer:

The relative reactivity of carboxylic acid derivatives toward nucleophile substitutions is related to the electronegative leaving group's ability to activate the carbonyl. The more electronegative leaving groups withdraw electron density from the carbonyl, thereby increasing its electrophilicity.

The standard voltage for the equation CuCl₂ + Zn —> ZnCl₂ + Cu is -1.1 Vol.

Voltage is the pressure of the charged electrons in an electric circuit which pushes the electrons towards the switch, which makes the light illuminate. By Ohm's law, voltage is equal to current x resistance.

V = IR

The reaction is CuCl₂ + Zn —> ZnCl₂ + Cu, which means it is a dry cell battery, where the anode, zinc reacts with chloride that is the cathode. In the dry battery cell, the chemical energy is stored in it, which converts into electrical energy.

The voltage will be minimum, which is -1.1. The liquid battery cells or the electric fittings in our house contain high voltages because it gets direct current, but dry battery cells contain minimum amount of voltage and it is used to operate small objects.

Thus, the standard voltage will be -1.1 Vol.

Part A; A stronger solution of sodium bicarbonate require more hydrochloric acid will be required

Part A; The reason why more HCl is required is due to the presence of more hydroxyl ions in the solution

The reason arriving at the above responses are as follows;

Part A

Sodium bicarbonate, NaHCO₃, is baking soda = A basic salt; has the capacity to deprotonate water

Hydrochloric acid, HCl = An acid

The reaction between sodium bicarbonate and hydrochloric acid is presented as follows;

NaHCO₃ + HCl → CO₂ + H₂O + NaCl

The equation for the ionic reaction is as follows;

Na⁺(aq) + HCO₃⁻(aq)  + H⁺(aq) + Cl⁻(aq)  → Na⁺(aq) + Cl⁻(aq) + H₂O(l) + CO₂(g)

In water, we have;

HCO₃⁻(aq) + H₂O(l) ⇄ H₂CO₃(aq) + OH⁻(aq)

The presence of a stronger solution of sodium bicarbonate, will produce more hydroxyl ions, OH⁻(aq), which will require, more HCl to neutralize

Therefore, if a stronger solution of sodium bicarbonate was used, more hydrochloric acid will be required

Part B

The solution of stronger sodium bicarbonate will contain a higher concentration of hydroxyl ions and therefore, require more HCl, to neutralize
