Answer:
For example, a suitcase jam-packed with clothes and souvenirs has a high density, while the same suitcase containing two pairs of underwear has low density. Size-wise, both suitcases look the same, but their density depends on the relationship between their mass and volume. Mass is the amount of matter in an object.
Answer:
True
Explanation:
Because anything that has mass also has gravity
Answer:
0.15 M KCl
Explanation:
(Step 1)
Convert the original volume from mL to L. Calculate the moles of the original solution.
75.0 mL / 1,000 = 0.0750 L
Molarity = moles / volume (L)
0.200 M = moles / 0.0750 L
0.0150 = moles
(Step 2)
Convert the final volume from mL to L. Calculate the final molarity.
100. mL / 1,000 = 0.100 L
Molarity = moles / volume (L)
Molarity = 0.0150 moles / 0.100 L
Molarity = 0.15 M
Answer:
. For each metal that participated in a chemical change, write the type of metal it is, based on yourexamination of the periodic table.Answer: Ammonium Vanadate appears to be mostly a post transition metal. Manganese sulfate also hasmore post transition atoms than transition atoms. Iron nitrate is a transition metal. The cobalt nitrate is atransition metal. Copper nitrate is a transition metal. Zinc nitrate is also a transition metal.(5 points)3. Were there any metallic compounds that did not react with either the acid or the base? Write the type ofmetal, based on your examination of the periodic table.4. Make a general statement about the reactivity of the metals in this experiment.Answer: The transition metals in this experiment were all reactive when mixed with one of the twosubstances. The alkali and alkaline earth metals, however, did not react at all.
