SOMEONE, PLEASE HELP If it takes 20 mL of 0.35 M H₂SO₄ to neutralize 50 mL of NaOH solution, what is the concentration of the NaOH solution?

According to coulomb's law, how would the electrical force between particles change if the product of their electrical charge increased?

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
