The reduction of a less active metal by a more active one is called metal displacement reactions. For example:
Fe + CuSO4 → FeSO4 + Cu
<h3>What is metal displacement reaction? </h3>
Displacement reactions is a reaction which includes a metal and the compound of a other metal. A more reactive metal will push or displace out a less reactive metal from its compound in this displacement reaction. The metal which is less reactive left uncombined after the reaction.
As we know that, electrons are the basis of the chemical reactions. If chemical compound or element A is more easily oxidized than B, then according to the terms of the activity series, the elements which are more easily oxidized can react with more chemicals, since they are able to act as a reducing agents for more chemicals.
Since, Metal ions are positively charged ions as they lose electrons. Some metals give up their electrons more readily than others and become more reactive.
Thus, we concluded that the reduction of a less active metal by a more active one is called metal displacement reactions. For example:
Fe + CuSO4 → FeSO4 + Cu

HETOOO.... MIXTURE ,,,!!!!!! Hope it helps....
Answer:
Directly Proportional
Explanation:
The partial pressure is defined as the pressure exerted by an individual gas that are present in a mixture as if it were alone in that particular system.
The kinetic molecular theory of gases is explained as the state of matter that is composed of tiny particles in constant motion even though there are distance between the colliding particles.They posses low density and Because of their nature gases can expansion and contraction of gas can be influenced under some condition.Unlike other fluid like liquids, the volume that gas usually occupied is empty space.
The gas particles are always in constant motion, and all the particles of the individual gases move and collide with one another and with the walls of the container they occupied. The magnitude of the gas pressure is been determined by the force with which they collide with one another.
Therefore,The rate at which collision occurs depends on the number of collisions which occur and this rate is directly proportional to the partial pressure of the vapor
Answer:
it's a double displacement reaction
Explanation:
I choose question 1, so molarity is the concentration of a soulution expressed as the number of moles of solute by the litress of soulution. to get molarity you divide the moles of soulute by the litress of solution. soo 1 calculate the number of moles of solute present. 2 Calculate the number of litress solution present. 3. divide the number of moles of solute by the number of litress of solution
soo 1 mol of NaOH has a mass of 40.00 g, so moles of NaOH= 26.7. 1 mole divided 40.00 = 0.375. litress of solution = 650 g. im not sure why its a g i usally do it Ls so i guess its the way your teacher wants you to do it so do you know how to do that. so molarity = moles of solute and litress solution. sorry this probably didnt help i just wanted to add something that might help. im still working on this stuff myself hope this helps.
