Answer:
-730KJ
Explanation:
According to the first law of thermodynamics;
Let the total energy of the system be ∆E
Let heat be q and let work the w
Since the energy decreases ∆E is negative
Since work is done on the system w= positive
So;
- 250 = 480 + q
q = -250 - 480
q=-730KJ
Answer:
Transferred from one atom to another
Explanation:
In a binary ionic compound, the electrons are transferred from one atom to another, thus forming positive and negative charges on the respective atoms involved, and thereby creating electrostatic forces which thus form the ionic bond.

Answer:
Taking water and oxygen from Earth is rather expensive and hard to do.
Explanation:
Without water and oxygen, travel to other planets is basically impossible
From the term itself extrasolar, this refers to the planet that revolves around a star outside from our own solar system. And the evidence that would show an existence of an extrasolar planet is a low-mass object as indicated in the Doppler-shifted stellar spectrum and physics calculation. The answer is option A.
