The answer would be how much greenhouse gas does your fuel produce compared with the current fuel sources.
hope this helps
Answer:
A
Explanation:
The molecules in both metal and surrounding air will start moving slower because of the sudden decrease in environment tmeperature. The thermal energy around the metal plate decreases, also decreasing the kinetic energy.
Answer: b- it is always a substance
Explanation: matter can be any liquid, gas, or solid that takes up space so the answer cannot be C or D. For answer number A to be true, you would have to remove the word more, because matter just has mass and takes up space it does not have "more mass"
Packing
Explanation:
Ionic crystals are brittle due to the tight packing of their crystals. This provides little to no mobility between one another.
- Brittleness implies having little to no elasticity.
- Ionic crystals are held together by strong crystal lattice forces
- These forces prevents crystals from freely rotating and moving space.
- It holds them rigidly and fixed in place.
- Ionic crystals are hard and held electrostatic forces.

The term isoelectronic atoms means that if the given atoms are neutral, they would have the same number of electrons, which is relative to their sizes. Ions with positive charges are called cations, losing electrons. On the other hand, ions with negative charges are called anions, gaining electrons. The more electrons that the atoms have, the bigger it is in size. Hence, the arrangement of the radii of the atoms would have to be,
e²⁺, d⁺, c , b⁻, a⁻
The arrangement is from smallest to largest.
