In the lab, you are given a metal ball. You measure the mass of the ball to be 28 g. You place the ball in a graduated cylinder and the water level increases from 28.2 mL to 31.4 mL. What is the density of the metal ball? (round you answer to the nearest hundredth)
Answer:
Density = 8.75ml
Explanation:
Density = Mass / Volume
In this problem ...
Mass = 28 grams
Volume = 31.4ml - 28.2ml = 32ml (water displacement also)
∴Density = mass /volume = 28g/32ml = 8.75g/ml

The water cycle describes the movement of water on Earth. Water in oceans and lakes evaporates and turns into water vapor. This water vapor condenses and forms clouds which produce precipitation. Precipitation falls all over the Earth's surface. The water eventually comes back to the oceans through run-off. Which steps in the water cycle carry water out of an ocean and into a freshwater lake?
A. Evaporation and precipitation
B. Rivers and streams
C. Underground tunnels
D. Condensation and run-off
Answer:
c. Underground tunnels
Explanation:
Yes, water below your feet is moving all the time, but, no, if you have heard there are rivers flowing below ground, that is not true. Water moves underground downward and sideways, in great quantities, due to gravity and pressure. Eventually it emerges back to the land surface, into rivers, and into the oceans to keep the water cycle going.
Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human interference.
The steps in the water cycle that carries water out of the ocean into a freshwater lake are rivers and streams.
What is the water cycle?The water cycle is used to describe the movement of water in the ecosystem. It involves the various processes through which water can move in the universe.

25.0 g Fe2CO3 reacts with 20.0 g CO in the reaction below. What is the limiting reactant and what best explains why is this reactant limiting?
Fe2CO3 + CO --> 2Fe + 2CO2
Answer:
In a chemical reaction, reactants that are not used up when the reaction is finished are called excess reagents. The reagent that is completely used up or reacted is called the limiting reagent, because its quantity limits the amount of products formed. It represents a reaction of a metal and a diatomic gas chlorine.

Which of the following is a distinguishing difference between rocks and minerals?
A. Minerals are aggregates of different rocks and elements.
B. Minerals have specific chemical compositions, but rocks do not.
C. Crystals are a type of rock and granite is a type of mineral.
D. Minerals are made of rocks combined in different combinations.
Answer:
B.
Explanation:
Minerals are formed due to chemical composition by rocks are pressured into their formed from dirt and naturally hard things.
The statement that represents a distinguishing difference between rocks and minerals is as follows:
Minerals have specific chemical compositions, but rocks do not.Thus, the correct option for this question is B.
What is the difference between rocks and minerals?A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition, and atomic structure. Rocks are generally made up of two or more minerals, mixed up through geological processes.
Minerals are definitely formed due to chemical composition by rocks being pressured into their formation from dirt and naturally hard things. A rock is an inorganic and a solid naturally-formed substance without any chemical composition or atomic structure.
A mineral is also a solid, inorganic, substance as that like a rock which has a definite crystalline structure as well as chemical composition. Rocks form, break down and move through the rock cycle.
Therefore, the correct option for this question is B.

how many atoms of alumminum are in 3.9 mol of aluminum
Answer:
2.35 x 10²⁴ atoms Al
Explanation:
Given 3.9 moles of aluminum (Al), determine number of aluminum atoms in that quantity of substance.
By definition a mole is the mass of substance containing one Avogadro's Number (N₀) of particles. That is, 1 mole = 1 N₀ = 6.023 x 10²³ particles*.
So, if 1 mole aluminum contains 6.023 x 10²³ atoms of aluminum then
3.9 moles Al = 3.9 moles Al x 6.023 x 10²³ atoms Al/mole Al = 2.35 x 10²⁴ atoms Al.
________________
*The complete equivalent relationship is ...
1 mole (atoms or compounds) = 6.023 x 10²³ atoms or molecules = 1 formula weight of the substance = 22.4 Liters (if in gas phase at STP conditions (0°C and 1atm pressure).
