Answer:
Base
Explanation:
acid + base = salt + water
Answer:
Roughly 323g of H2O.
Explanation:
Balance your chemical equation:
1 Fe3O4 + 4H2 → 3 Fe + 4 H2O
Modulate your stoichiometry 4 steps:
Answer: If you want to change the pitch of a sound, you have to change the <em>frequency.</em>
Explanation:
Pitch is the quality of the sound to judge it has higher or lower.The frequency of the sound wave is perceived as pitch.Pitch and frequency of the sound are related to each other
- If want to increase the pitch we have to increase the frequency of the sound.
- If want to decrease the pitch we have to decrease the frequency of the sound.
If you want to change the pitch of a sound, you have to change the <em>frequency.</em>
Answer:
The order in which the orbitals is filled is 1s-2s-2p-3s-3p-4s-3d-4p-5s-4d-5p-6s-4f-5d-6p-7s-5f-6d-7p
Explanation:
S orbitals each hold two electrons, p orbitals hold 6, d orbitals hold 10, and f orbitals hold 14. 1s has the least energy and 7 p has the greatest energy, so the order in which they are filled is listed above.
Answer:
Because of the less reactivity of copper.
Explanation:
As well as being resistant to the elements and thereby less likely to be affected by rainfall, hail, and mildew than other types of roofing, copper is also one of the most fireproof materials available. Copper is also highly resistant to thermal changes and thereby doesn't deteriorate quickly.
Magnesium would also corrode PDQ. Magnesium sheeting would also pose an unacceptably high fire hazard.
