Answer:
Explanation:
<h3>Chemical Reaction:</h3>
<u>From the reaction, we can say that,</u>
- 1 mole of propane and 5 moles of oxygen produce 4 moles of water and 3 moles of carbon dioxide.
So, to generate 3 mole of carbon dioxide, 5 moles of oxygen are required. (as shown in the chemical reaction!)
Answer:
The final temperature is 20.3 °C
Explanation:
Considering that:-
Heat gain by water = Heat lost by brass
Thus,
Where, negative sign signifies heat loss
Or,
For water:
Mass = 300.0 g
Initial temperature = 20.0 °C
Specific heat of water = 4.184 J/g°C
For brass:
Mass = 19.0 g
Initial temperature = 81.7 °C
Specific heat of water = 0.375 J/g°C
So,
<u>Hence, the final temperature is 20.3 °C</u>
Size
The Sun is 1,390,000 km in diameter. That compares with 12,756 km for diameter of the Earth. In other words, the diameter of the Sun is over 100 times the diameter of the Earth.
In June, 2004, Venus passed in front of the Sun, as seen from the Earth. Since the diameter of Venus is only slightly less than that of Earth (12,104 km)
Mass
The mass of the Sun is about 2 x 1030 kilograms (2 followed by 30 zeros). It is one of the larger stars in our Milky Way galaxy. The median size of stars in our galaxy is less than half the mass of the Sun. In comparison, the Earth is 6 x 1024 kg. This means that the mass of the Sun is over 300,000 times greater than that of the Earth.
