Answer:
Total energy consumed = 1,882.8 joules
Explanation:
Given:
Calories burned = 450 calories
Find:
Total energy consumed
Computation:
1 calorie = 4.184 joules
So,
450 calories = 4.184 × 450
450 calories = 1,882.8 joules
Total energy consumed = 1,882.8 joules
Answer:
Avogrado's number
Explanation:
It's unniversal measure of moles
Answer : The correct option is, (A) silver ion gains electrons more easily and is a stronger oxidizing agent than a chromium(III) ion.
Explanation :
The given half reaction are :
1st half reaction : 
The reduction potential of this reaction = +0.80 V
2nd half reaction : 
The reduction potential of this reaction = -0.74 V
From the reduction potentials, we conclude that the reaction which have positive reduction potential, they will gain electrons more easily and reduced itself and act as a stronger oxidizing agent.
Or we can say that the reaction which have negative reduction potential, they will lose electrons more easily and oxidized itself and act as a stronger reducing agent.
The reduction potential of 1st half reaction is positive and 2nd half reaction is negative.
Therefore, the silver ion gains electrons more easily and is a stronger oxidizing agent than a chromium(III) ion.
It can be done by you only
- First observe the figure or model .

- Then write it uses and why it is commercial most usable.
Answer:
1. CARBON DIOXIDE- it is a covalent compound, which is used in soft/cold drinks and some other fluids as well , and use it in daily life.
2. HYDROGEN MONOXIDE- it is the normal or original or pure water which we drink everyday in our daily life and it is very important for our survival
