Answer : The balanced molecular equation will be:
Explanation :
Molecular equation : It is a balanced chemical reaction in which the ionic compounds are expressed as the molecules instead of component ions.
According to the question, when iron react with copper (II) sulfate then it react to give iron (II) sulfate and copper as a product. In this reaction, iron is more reactive metal than the copper metal. So, it can easily displace copper metal form the solution.
The balanced molecular equation will be:
Answer:
Yes
Explanation:
You add more force behind the cart with the higher mass. Assuming that its higher mass causes it to weigh more.
Answer:
Electric engines have efficiencies of roughly 90% whilst combustion engines about 10% to 30%. This is because combustion engines emit much more heat, which is always energy that is not used as work, and thus increases inefficiency.
Explanation:
The molarity of a solution if it tale 12.0 grams of Ca(No3)2 is calculated as below
molarity = moles/volume in liters
moles = mass/molar mass = 12.0 g/ 164 g/mol = 0.073 moles
molarity is therefore = 0.073/0.105 = 0.7 M
