Stalactites and stalagmites are examples of _____.organic sedimentary rock
contact metamorphism
extrusive igneous rock
chemical sedimentary rock

Answers

Answer 1

Answer:

The right option is; chemical sedimentary rock

Chemical sedimentary rocks are rocks that are formed by precipitation of minerals from water. Chemical sedimentary rocks are also called evaporates and they are usually composed of the minerals halite (calcium chloride) and gypsum (calcium sulfate). Examples of chemical sedimentary rocks include stalactites, stalagmites, rock salt, flint, and some dolomites.

Answer 2

Answer:

Answer:

The correct answer is option D, chemical sedimentary rock

Explanation:

Both stalactites and stalagmites are called drip stone as they are formed of the dripping water consisting of minerals. Both stalactites and stalagmites hang up from the ceiling of caves. These are also refereed to as Chemical sedimentary rocks formed by precipitation. The three major processes involved in the formation of these two rocks are –

a) Physical weathering – which disintegrates the minerals contained in the igneous, sedimentary, or metamorphic rock

b) Chemical weathering – which involves dissolution of weathered rock minerals

c) Precipitation of the dissolved minerals.

What is the affect of increasing the water's mass?how does it reflect it's temperature?

Cold packs are used to treat minor injuries. Some cold packs contain NH4NO3(s) and a small packet of water at room temperature before activation. To activate this type of cold pack, the small packet must be broken to mix the water and NH4NO3(s). The temperature of this mixture decreases to approximately 2°C and remains at this temperature for 10 to 15 minutes.State the direction of heat flow that occurs when the activated cold pack is applied to the body.
Identify both types of bonds in the NH4NO3(s).

Answers

These types of reactions are called endothermic reactions. This is when the system absorbs the heat from the surrounding. In this case, the system is the chemical reaction and the environment is the direct vicinity of the chemical reaction. You notice that the pack becomes cold because heat from the surrounding is being absorb.

The bonds involved in this substance includes ionic bonding and polar covalent.

Electrons are capable of emitting energy in the form of light at very narrow ranges of wavelengths. These wavelengths can be measured to find the electron's a. mass.
b. density.
c. energy level.
d. specific heat.

Answers

The correct answer is (C) energy level.

The explanation:

When the electrons release photons , and those photons are at different levels

of energy . So we can define the electron's energy level from this photons which

tell us the energy level they are on.

C. Electrons release photons at different energy levels which would tell us which level they are on.

Which of these would be easily soluble in water?a. salt
b. oil
c. aluminum foil

Answers

A) Salt, because salt can easily dissolve in water. Oil would not dissolve or evaporate in water (think of an oil spill - does that oil dissappear?). Aluminum foil would definitely not dissolve in water, so it is not soluble.

Answer:

salt

In kinetics, the order of a reactionA)depends on the rate constant
B)can be deduced from the balanced equation for the reaction
C)must be measured experimentally
D)depends on the concentrations of reactants
E)is the inverse of the entropy of the system

Answers

I think it should be C. You can't always look at the chemical equation of a reaction and tell what order the over all reaction will be. To do this, you need to preform experiments that have some concentrations held constant while changing others to see how the concentrations affected the rate. After enough trials with enough concentrations held constant and changed, you will be able to determine the order of each reactant which will give you the order of the overall reaction.

I hope this helps. Let me know in the comments if anything is unclear.

If you put a straw into a glass of water, the straw looks to be bent, although nothing has physically happened to the straw. The term that describes this property of light isA) absorption.
B) diffraction.
C) reflection.
D) refraction.

Answers

The study of matter is called physics.

The correct answer to the question is option D which is refraction.

What is refraction?

Refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.
Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction

According to the question, If you put a straw into a glass of water, the straw looks to be bent, although nothing has physically happened to the straw. The term that describes this property of light is called refraction.

Hence, the answer is Refraction.
