0.25 mols SO₂ x 64.058 g SO₂/ 1 mol SO₂ = 16.0145 g SO₂
molar mass of SO₂: 64.058 g
answer: 16 grams of SO₂ (2 sig figs)
check the question to see if its asked for a specific unit for mass (grams or kilograms, if they asked for kiligrams then convert 16 grams to kilograms by dividing it by 1000)
Answer:
Climate change and climate dramaticlly affect my lifestyle and day to day life.
Explanation:
Answer:
Electrical energy to mechanical energy
Explanation:
In an electric motor, the energy transformation that is involve is a move from from electrical energy to mechanical energy.
For every system, according to the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".
- An electric motor converts electrical energy to mechanical energy
- The electrical energy passes through and electromagnet set up.
- This then cause the motion to rotate.
- Therefore, electrical energy is transformed to mechanical energy.
The correct answer is option D, that is, a storage battery is charged using an electric current.
The transformation of one form of energy into another, generally to transform the energy into more useful kind is known as energy conversion. The energy can neither be created nor be destroyed, it can only be transformed. The different forms of energy comprise light, heat, mechanical, electrical, sound, nuclear, and sound.
In the given question, the charging of a storage battery using electric current is an example of electrical energy being converted into chemical energy.
The volume of a gas that its pressure increase to 3.4 atm is calculated as follows
By use of boyles law that is P1V1=P2V2
V1=4.0 L
P1=1.1 atm
P2=3.4 atm
V2= P1V1/P2
(1.1 atm x 4.0 L)/3.4 atm= 1.29 L
