Distillation of a mixture
Mendeleev’s arrangement of elements in the periodic table was based on the observations and experiments of his predecessors who studied mass and properties of elements is TRUE.
<u>Explanation:</u>
In Mendeleev’s periodic table, elements were ordered according to their atomic masses. This is the fundamental property on which Mendeleev's periodic table is based on.
Mendeleev has also formulated a periodic law which states that the properties of elements are the "periodic function of their atomic masses". However, due to the anomalies that were created in his periodic table, we don't use this periodic table and prefer modern periodic table that is based on property of atomic number.
Answer:
As per Newton's first laws of motion, everybody continues to be at state of rest or of uniform motion in a straight line unless and until it is compelled by some external unbalanced forces acting on it.
Hence, it is the unbalanced force that changes the state of rest or motion of a body. Balanced force is responsible for keeping the body to be either in static equilibrium or in dynamic equilibrium.
As per the options given in the question, the last one is true for an object under balanced forces.
sorry if this doesn't work
The product will not be affected by the addition of twice as much Na₂CO₃.
<h3>What is Limiting reagent in stoichiometry ?</h3>
- The maximum quantity of the end product determined by a balanced chemical equation is known as the Stoichiometry.
- The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced, and the one which remains unconsumed after the final reaction is in Excess.
- Calculate the moles of each reactant present and contrast it with the mole ratio of the reactants in the balanced equation to determine which reactant is the limiting one.
Here,taking the stoichiometry into consideration, we find that the reaction happens with 1:1 ratio; so, adding twice the amount of Na₂CO₃ will lead to its excess making the other the limiting reactant, hence, it would not affect the yield of the product.
