Answer:
Mass of iron = 59.375 gm
Explanation:
Calories ( or joules) are added to the water by the hot steel so at the endpoint they are BOTH at 40 C
The water gains:
4.18 j/g-C * 50 * (40-30 C) = 2090 j
The steel gave up 2090 j going from 120 to 40 C
2090 = .44 j/g-C * m * (120-40) solve fro m = 59.375 gm
D. because the size and shape of the slope determines weather the load can be sustained and c is correct too because the shape affects how much you can load and b. is correct as also because if the volume is very large it can affect the rivers load and flow.

Answer:
2:8
Explanation:
The reaction equation is a given as:
2C₄H₁₀ + 130₂ → 8CO₂ + 10H₂O
From the reaction equation, the mole ratio is 2:8
Butane is C₄H₁₀
Carbon dioxide CO₂
From the reaction;
2 moles of butane will produce 8 moles of carbon dioxide
Don’t really understand what you’re asking but, if you’re asking how to read a graduated cylinder:
Look at the graduated cylinder at eye level, find the meniscus, whatever the meniscus is at is your answer.
