Answer: m= 0.69 m or mol/kg
Explanation: Molality is expressed as moles per unit kilograms of solvent or m= n / kg
First convert 25.0 g NaCl to moles
25.0 g NaCl x 1 mole NaCl / 58 g NaCl
= 0.43 moles NaCl
Next convert 625 g H2O to kilograms
625 g H2O x 1 kg / 1000 g H2O
= 0.625 kg H2O
Substitute the values in the formula
m = n / kg
= 0.43 mole NaCl / 0.625 kg
= 0.69 m or mole / kg
Answer:
A 400,000 kg object and a 100,000,000kg object
Explanation:
The objects with the most mass between them will have the greatest gravitational attraction.
This is why the last option is the right choice.
The reason for this is based on the Newton's law of universal gravitation which states that:
"the gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them".
So, the more the mass, the greater the gravitational attraction between two bodies.
Answer:
1: A.) adapted
2: A.) habitat destruction
Explanation:
Some (few) animals are capable of adjusting their behaviors in relation to human activity and the changes humans make in their habitat. Most are so well adapted to the details of their habitat that they are incapable of surviving when those details change.
"Because all organisms are <u>adapted</u> to their native habitat, human activities that result in <u>habitat destruction</u> are a major reason for their extinction."

<em>Comment on human activities</em>
My friendly local rodent exterminator observed that rodent activity has picked up substantially, since so much human activity has been curtailed by quarantine orders.
