Sustainable living is a lifestyle adopted by individuals or societies which is geared towards reducing the consumption of earths natural resources. The idea is to lower the carbon footprint by switching to sustainable modes of transport, living spaces, food consumption etc.
In the given passage, the sentences that describe sustainable living are:
1) 'I plan to buy a hybrid for better gas mileage': Since a hybrid is a combination of a petrol engine and an electric motor, it reduces the consumption of fuel and is more energy efficient.
2) 'I am able to carpool with a couple of friends from work' : Carpooling reduces the vehicles on road thereby reducing vehicle exhaust.
3) 'The architects received a LEED certification': LEED certified buildings are energy efficient constructions.
Answer:

Answer:
Yes!
Explanation:
4Al + 3O2 -> 2Al2O3
4 Al's on the left side
6 O's on the left side
4 Al's on the right side
6 O's on the left side
This is balanced! Let me know if you need help with any other equations.
Answer:
64,433.6 Joules
Explanation:
<u>We are given</u>;
- Volume of water as 220 mL
- Initial temperature as 30°C
- Final temperature as 100°C
- Specific heat capacity of water as 4.184 J/g°C
We are required to calculate the amount of heat required to raise the temperature.
- We know that amount of heat is calculated by;
Q = mcΔT , where m is the mass, c is the specific heat, ΔT is the change in temperature.
Density of water is 1 g/mL
Thus, mass of water is 220 g
ΔT = 100°C - 30°C
= 70°C
Therefore;
Amount of heat, Q = 220g × 4.184 J/g°C × 70°C
= 64,433.6 Joules
Thus, the amount of heat required to raise the temperature of water is 64,433.6 Joules
