Explanation:
This is feasible single displacement chemical reaction. In this reaction, Zinc displaces cadmium from the chlorate solution:
Zn + Cd(ClO₃)₂ → Zn(ClO₃)₂ + Cd
A single displacement reaction is a reaction in which one specie replaces another.
The main driving force in this kind of reaction is the position of the displacing species in the activity series.
In the series, metals that are higher up are more reactive and they will displace the lower ones from solution.
Cadmium is lower in the series and Zn is higher up.
Zn is more reactive than Cd and will displace it form the solution and it gives the expression:
Zn + Cd(ClO₃)₂ → Zn(ClO₃)₂ + Cd

Answer:
Because the specific heat of the metal is less than the specific heat of water.
Explanation:
Hello, happy to help you today!
In this case, we need to analyze a property called "specific heat" which accounts for how much energy is required to increase or decrease the temperature of 1 g of the substance by 1 °C.
In this case, since the specific heat of water is about 4.184 J/g°C and the specific heat of metals in general is greater than zero, of course, but less than one, we can infer that for the same amount of energy, when they are in contact, more grams of metal will be cooled down to those of water heated up, because the specific heat of the metal is less than the specific heat of water.
Best regards!.

When studying atoms, scientists can ignore <u>the Gravitational</u> force between charged particles that make up the atoms because it is many millions of times smaller than other forces in the atom.
Explanation:
Scientists can ignore the gravitational force because the gravitational force is considered to be negligible as compared to the other forces due to its smaller value.We all know that the gravitational force is directly proportional to the mass of an object which result in a small force value.When the value of this small force is compared to the value of the electrical force between protons and electrons in atoms the we can say that the electrical force is million times stronger than the gravitational force
Thus we can say that scientists can ignore <u>the Gravitational</u> force between charged particles that make up the atoms because it is many millions of times smaller than other forces in the atom.
