Acids react with metals to form hydrogen gas.
This shape is found when there are four bonds all on one central atom, with no extra unshared electron pairs. In accordance with the VSEPR (valence-shell electron pair repulsion theory), the bond angles between the electron bonds are arccos(−1/3) = 109.47°.
Answer:
well, it increased by 40 km/hr in 9 s, so the acceleration is
40/9 km/(hr-s)
Explanation:
25 cm x 12 cm x 13 cm => 3900 cm³
1 cm³ = 1 mL , therefore: 3900 x 1 => 3900 mL
hope this helps!
