Answer:
kilogram
Explanation:
because kilogram is equal to thousand grams
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
The answer is a. a homogenous mixture
B, THE PH OF ACID IS ALWAYS BETWEEN 0 AND 7, BUT REMEMBER THAT 7 IS NEUTRAL
I’m going to go with The pH 1 solution is two times more acidic than that with a pH of 1. If that’s not the answer, then my second best guess would be The pH solution is ten times more acidic than that with a pH of 2.
The first and third answer choice wouldn’t even be an answer so you can just cancel those two out and pick between answer choice 2 or 4.
Hope this helps, and have an amazing day!! :))
