HOW MANY GRAMS OF NAOH ARE NEEDED TO MAKE 500ML OF 2.5M NAOH

Maple syrup which comes from the sap of maple trees contains water and natural sugars its clear brown liquid and the sugar cant

Maple syrup is a homogeneous mixture, because it's uniform in composition (sugar is uniformly dissolved in water). Homogeneous mixture can be separated by<span> taking advantage of the different properties of the individual components such as distillation, but not by filtration.</span>

How could two objects have the same temperature but different thermal energies? One object could have more particles and greater

Tju [1.3M]

Answer:

One object could have more particles and greater total kinetic energy

Explanation:

The higher the temperature the more the particles. So, when we have high temperature, there is more particles interacting.

Temperature can simply be defined or gotten by taking the average of of the kinetic energy of the particles in the object that is the keywords here are TAKING THE AVERAGE KINETIC ENERGY

Thermal energy is the energy that can be gotten from adding up all the total kinetic energy of the particles in the object. So, the keywords here are; ADDING UP THE TOTAL KINETIC ENERGIES.

So, when two particles of the same temperature have the different thermal energy it means that One object could have more particles and thus having greater total kinetic energy.

If a reaction mixture contains 24 g of Mg and 32 g of O2 , what is the limiting reactant?

Alexxx [7]

This problem is providing the mass of both magnesium metal and oxygen gas and involved in a chemical reaction and asks for the limiting reactant. At the end, it turns out to be identified as magnesium.

<h3>Stoichiometry</h3>

In chemistry, stoichiometry is a widely-used tool we use in order to relate the mass and moles of different chemical substances involved in a chemical reaction. Thus, we consider the following chemical equation between magnesium and oxygen to produce magnesium oxide.

$2Mg+O_2\rightarrow 2MgO$

However, when the mass of the both of the reactants is given, one must identify the limiting reactant as the one producing the least of the moles of the product, which means we can use the given grams of the both of the reactants, their molar masses and mole ratios with the product to obtain the aforementioned:

$24gMg*\frac{1molMg}{24.3gMg}*\frac{2molMgO}{2molMg}=0.988molMgO\\ \\ 32gO_2*\frac{1molO_2}{32.0gO_2}*\frac{2molMgO}{1molO_2}=2molMgO$

Thus, we can evidence how 24 g of magnesium produce the least of the moles of magnesium oxide, fact validating the magnesium as the limiting reactant and the oxygen as the excess one.
