Different organisms have different "habitats." These are all examples of habitats: The tops of banana trees in a rainforest The moist area inside a log on a forest floor The sand on the bottom of a shallow area of the ocean Which survival need best defines "habitat"? oxygen or carbon dioxide someplace to live food water
Answer:
Oxygen/Carbon dioxide
Explanation:
The basic description of living things are organisms which have a cell system to produce energy with either primarily via respiratory exchange abilities, by the existence .
The primal survival need for a possessing a habitat would have to be oxygen/carbon dioxide present,

If 24.1 g of sodium hydroxide react with 22.0 g of hydrochloric acid to form 35.3g
of table salt, how much water was formed? *
Answer:
10.85 g of H2O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
NaOH + HCl —> NaCl + H2O
Next, we shall determine the mass of NaOH that reacted and the mass of H2O produced from the balanced equation.
These can be obtained as illustrated below:
Molar mass of NaOH = 23 + 16 + 1 = 40 g/mol
Mass of NaOH from the balanced equation = 1 × 40 = 40 g
Molar mass of H2O = (2×1) + 16 = 2 + 16 = 18 g/mol
Mass of H2O from the balanced equation = 1 × 18 = 18 g
Summary:
From the balanced equation above,
40 g of NaOH reacted to produce 18 g of H2O.
Finally, we shall determine the mass of water, H2O produced from the reaction as follow:
From the balanced equation above,
40 g of NaOH reacted to produce 18 g of H2O.
Therefore, 24.1 g of NaOH will react to produce = (24.1 × 18)/40 = 10.85 g of H2O.
Therefore, 10.85 g of H2O were produced from the reaction.

rings. Justin decides to go ahead and get started with the lab. He begins weighing chemicals, touching
ihem with his hands. He gets an itch in his nose and rubs it with his hand.
Question part in the given data is missing, however the missing part is as follows:
What safety rules were violated?
Answer:
The correct answer would be:
-Never work in the lab without teacher or adult present
-Keep chemicals away from hands and face.
-Do not touch lab supplies without permission
Explanation:
According to the lab safety and precaution rules one should follow the lab rules strictly to avoid any risk and mishap. These rules include, the chemical management, lab safety equipment, and many other rules including don not work in absence of teacher or the adult.
One should avoid touching chemical and equipment without permission of teacher and never touch chemicals with bare hand and not to touch chemical and keeps it from face.

Answer:
its a heterogeneous mixture.
Explanation:
The heterogeneous mixture has a non-uniform composition and has two or more phases. It can be separated out physically.
A homogeneous mixture is a solid, liquid or gaseous mixture that has the same proportions of its components throughout any given sample. Conversely, a heterogeneous mixture has components in which proportions vary throughout the sample.
Examples of Heterogeneous Mixtures
Sugar and sand form a heterogeneous mixture. If you look closely, you can identify tiny sugar crystals and particles of sand. Ice cubes in cola form a heterogeneous mixture. The ice and soda are in two distinct phases of matter (solid and liquid).
Periodic Table: Which families are highly reactive? Which family is unreactive?
The families that have the highest reactivities are the a lkali metals and earth alkali metals . These are located far left on the periodic table. They are highly reactive because they have an shell with only 1 electron and need to complete the shell to become stable. The family that is unreactive is inert elements or noble gases.
The alkali metals (lithium family) are highly reactive while the noble gases (helium family) are highly unreactive.
What are alkali metals?The alkali metals are the elements of group 1 in the modern periodic table which are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
All alkali metal has their outermost electron in the s-orbital with the outer configuration ns¹. The alkali metals easily lose the outermost electrons to form cations with charge + 1. Therefore they are highly reactive and are stored under oil to stop the reaction with air.
The noble gases have completely filled electronic configurations. The noble gases have a general outer configuration ns²np⁶ so they have completely filled valence shell therefore, they do not feel any attraction for other atoms. Therefore, noble gases exist in monoatomic form. Therefore, noble gases are highly unreactive and also known as inert gases.

During freezing, a substance? -loses chemical energy -loses thermal energy -gains thermal energy -gains chemical energy
The process of melting a crystalline solid can be
reversed if the liquid is cooled. The change from the liquid state
to the solid state is called freezing. As the liquid cools, it loses
thermal energy. As a result, its particles slow down and come
closer together. Attractive forces begin to trap particles and the
crystals of a solid begin to form.
"The total kinetic energy of all the particles in a sample of
matter is called thermal energy. Thermal energy, an extensive
property, depends on the number of particles in a substance as
well as the amount of energy each particle has. If either the
number of particles or the amount of energy in each particle
changes, the thermal energy of the sample changes. With identically sized
samples, the warmer substance has a greater thermal energy."

Explanation:
What is a sediment and how it is formed?
Answer:
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.
Im not sure if this answers your question but here!
Sedimentary rocks are one of three main types of rocks, along with igneous and metamorphic. They are formed on or near the Earth’s surface from the compression of ocean sediments or other processes.

A metal cube has a mass of 20 g and a volume of 5 ml. What is the density? Is the cube made of pure aluminum? Explain your answer in the "other" area. * A.2.7 g/mL B.4 g/mL C.100 g/ml D.Yes it is aluminum E.No it is not aluminum Other:__________________________________________________________
Explanation:
Given that,
Mass of metal cube, m = 20 g
Volume of cube, V =5 mL
We need to find the density of the cube. Mass per unit volume equals density.
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{20\ g}{5\ mL}\\\\d=4\ g/mL[/tex]
So, the density of the cube is 4 g/ml.
We know that the density of Aluminium is 4 g/mL.
So, the cube is not Aluminium cube.
The density of Aluminium is 2.7 g/mL. The cube is not the Aluminium cube.So, option B and E is correct
Mass of metal cube, m = 20 g
Volume of cube, V =5 mL
The formula for density is as follows:-
[tex]Density=\frac{Mass}{Volume} \\\\[/tex]......(1)
Substitute 20 g for mass, and 5 ml for volume in the above equation as follows:-
[tex]Density=\frac{20\ g}{5\ mL} \\\\=4\ g/mL[/tex]
So, the density of the cube is 4 g/ml.
We know that the density of Aluminium is 2.7 g/mL. So, the cube is not the Aluminium cube. So option B and E are correct.

1. Explain how this chemical reaction represents the law of conservation of matter.
Answer:
This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.

The allowable concentration level of vinyl chloride, C2H3Cl, in the atmosphere in a chemical plant is 2.0 x 10-6 g/L. a. How many moles of vinyl chloride in each liter does this represent?
Answer:
3.2x10⁻⁸ moles of vinyl chloride per liter
Explanation:
The concentration of C₂H₃Cl is 2.0x10⁻⁶g/L. To find moles per liter we need to convert this mass to moles using molar mass of vinyl chloride:
Molar mass C₂H₃Cl:
2C = 2*12g/mol = 24
3H = 3*1g/mol = 3
Cl = 1*35g/mol = 35
Molar mass = 35g/mol + 3g/mol + 24g/mol = 62g/mol
2.0x10⁻⁶g * (1mol / 62g) =
3.2x10⁻⁸ moles of vinyl chloride per literA "carat" is a unit of mass defined as exactly ⅕ of a gram. There are exactly 5 carats in a gram. How many carats would a 1.0 mL diamond have?
Answer:
17.55 carats
Explanation:
First, there is a need to know the mass of 1.0 mL of diamonds. The density of diamond is 3.51 g/mL and density is the ratio of mass and that of volume. Hence;
mass of diamond = density of diamond x volume.
Since the volume of the diamond is 1.0 mL and the density is 3.51 g/mL,
mass of 1.0 mL of diamond = 3.51 x 1.0 = 3.51 g.
1 g = 5 carats, therefore 3.51 g would be;
3.51 x 5 = 17.55 carats.
Hence, there would be 17.55 carats of diamond in 1.0 mL of diamond.
