Answer:
The answer is "freezing and melting sublimating x y".
Explanation:
In the given question, the given table name is used as the matter condition, which is freezing or melting sublimation x y, that must be the best headings throughout order to cancel a column of state of matter.
The process goes from the solid-state to a gaseous state, that is achieved by bringing heat into another system.
Answer: 18L
Explanation:
Solving this question would be easier by assigning variables.
so, let x = amount of 67% needed solution
Let y = amount of 42% needed solution.
From the question, we know that
x + y = 42 thus,
y = 42 - x
we also know that the pure herbicide in the 67% solution plus the herbicide I'm the 46% solution must be equal to the amount of pure herbicide in the final solution. Thus mathematically, we have
0.67x + 0.46y = 0.55*42
0.67x + 0.46y = 23.1
Remember, y = 42 - x, substituting this value, we have
0.67x + 0.46(42-x) = 23.1
0.67x + 19.32 - 0.46x = 23.1
0.21x = 23.1 - 19.32
0.21x = 3.78
x = 18
.therefore the amount of 67% solution needed is 18L
Among the choices given, the best answer is the third option. Melting ice shows an increase in entropy. Entropy is the degree of disorderliness in a
system. Among the phases, solid has the most ordered structure which means it has the least entropy. The ice melting shows a phase change from solid to liquid. Liquid molecules are more disorganized than the solid thus there is an increase in entropy.
Cl2 is the reduced substance
