You must use the Periodic Table. Metals, on the right side, will be positive. Non-metals, left, are negative. You need to know the specific ionic charge elements.
The specific heat capacity of liquid water is 4.186 J/gm K. This means that each gram of liquid water requires 4.186 Joules of heat energy to raise its temperature by one degree Kelvin. One molar mass of water is equivalent to 18 grams. Therefore, the molar heat capacity becomes the product of 4.186 and 18
Answer:
The answer to your question is 330 g of CHO
Explanation:
Data
Calories needed = 2200 kcal/day
CHO = 60%
Proteins = 15%
Fats = 25%
Grams of carbohydrates needed = ?
Process
1.- Calculate the number of calories in 60% of 2200 kcal
2200 kcal ---------------- 100%
x --------------- 60%
x = (60 x 2200) / 100
x = 1320 kcal
2.- Calculate the grams of CHO
1 g of CHO ---------------- 4 kcal
x ---------------- 1320 kcal
x = (1320 x 1) / 4
x = 1320/4
x = 330 g of CHO
Answer:
c = 0.38 J/(g-°C)
Explanation:
Given that,
Mass of copper, m = 5 g
Initial temperature,
Final temperature,
When copper cools, it looses 23.6 J of heat. We need to find the specific heat of copper. The heat lost is given by :
c is specific heat
Hence, the correct option is d.
Answer:
1330 mm Hg
1 atm = 760 mm Hg
there will be a multiplication or division based on the direction of the change
