Experimental design definition

Draw the alkyne formed when 1,1-dichloro-4-methylpentane is treated with an excess of a strong base such as sodium amide. (give the neutralized alkyne product, not the acetylide salt.)

Sodium hydroxide, NaOH; sodium phosphate, Na3PO4; and sodium nitrate, NaNO3, are all common chemicals used in cleanser formulation. Rank the compounds in order from largest mass percent of sodium to smallest mass percent of sodium.

Which phase change has more kinetic energy:boiling or melting?

The salt that is formed during the reaction between potassium hydroxide and hydrochloric acid is

Two groups complete an experiment requiring the mass measurement to be repeated three times in the experiment. Group I selects a single member of the group to measure the mass.

Since particles in a solid are arranged close together in a regular pattern, some can be classified as i think magma not 100% sure A. gradients. B. crystals. C. plasma. D. magma.

Two examples of common items that use chemical change

Give two sources of energy that can cause ocean waves

Chromium, calcium, and potassium are near each other on the periodic table and have some common characteristics but differ in chemical reactivity.

Which is true of transition metals when moving from left to right on the periodic table? The d sublevels are not filled across the period. The cation radii become larger across the period. Atomic radii increase slightly and then start to decrease.
