Now, observe and record the following:
state of matter:
appearance and texture:
crystalline structure:
Answer:
liquid no not a solid
Explanation:
When you put the substance in a 25 mL beaker. then the state of matter is solid, appearance and texture are powdered and crystalline structure is not solid(powder).
What are crystalline structures and states of matter?The term "crystalline structure" refers to the arrangement of atoms, ions, or molecules in a crystalline solid. A crystalline solid is a type of material where the constituent particles are arranged in a regular, repeating pattern. This regular arrangement results in a characteristic geometric shape for the crystals. Examples of crystalline solids include salt, sugar, and diamond.
On the other hand, the term "state of matter" refers to the physical form in which matter exists. There are three primary states of matter: solid, liquid, and gas.
Solids have a definite shape and volume and their constituent particles are held tightly together by strong intermolecular forces.
Liquids have a definite volume but no definite shape, and their constituent particles are held together by weaker intermolecular forces.
Gases have no definite shape or volume, and their constituent particles are far apart and move freely.
Other states of matter, such as plasma and Bose-Einstein condensate, also exist but they are less common in everyday life.
Therefore, the state of matter: is solid, its appearance and texture: are powdered, and the crystalline structure: is not solid.

Which ion has the correct charge?
07-
Na 2+
N 3+
Ca2+
Answer:
Ca(2+)
Explanation:
Sodium (Na) only have one valence electron and will lose it in order to gain a full octet. There will be an unbalance of electrons and protons where there are more protons there electrons. The correct ion formula for sodium is Na (1+).
Nitrogen has 5 valence electrons and will gain three more to gain a full octet. There will be an unbalance where there are more electrons then protons. Nitrogen will form the ion N (3-).
Calcium has two valence electrons and will lose them in order to gain a full octet. There will be an unbalance where there are more protons then electrons. Calcium will form the ion Ca 2+
Therefore, Ca2+ is the ion with the correct charge.

What is the molarity of a HCl solution, if 28.6 mL of a 0.175 m NaOH solution is needed to neutralize a 25.0 mL sample of the HCl solution
The molarity of the HCl solution needed to neutralize 28.6 mL of a 0.175 M NaOH solution is 0.2002 M
We'll begin by writing the balanced equation for the reaction. This is given below:
HCl + NaOH —> NaCl + H₂O
From the balanced equation above,
The mole ratio of the acid, HCl (nA) = 1
The mole ratio of the base, NaOH (nB) = 1
From the question given above, the following data were obtained:Volume of base, NaOH (Vb) = 28.6 mL
Molarity of base, NaOH (Mb) = 0.175 M
Volume of acid, HCl (Va) = 25 mL
Molarity of acid, HCl (Ma) = ?The molarity of the acid, HCl can be obtained as follow:
MaVa / MbVb = nA / nB
(Ma × 25) / (0.175 × 28.6) = 1
(Ma × 25) / 5.005 = 1
Cross multiply
Ma × 25 = 5.005
Divide both side by 25
Ma = 5.005 / 25
Ma = 0.2002 MTherefore, the molarity of the acid, HCl needed for the reaction is 0.2002 M

Which of the following are elements? (Select all that apply.)
KCl
Na
C
H2O
Answer:
Na(Sodium) and C(Carbon) only
Answer:
Na, C
Explanation:
1. KCl, or potassium chloride, is a combination of two elements- so it's a chemical compound.
2. Na, or sodium, can be found on the periodic table of elements. Therefore, it is an element.
3. C, or carbon, can also be found on the periodic table of elements. Therefore, it is an element.
4. H20, or water, is a combination of 2 hydrogen atoms that bonded into an oxygen atom. Combination of 2 or more elements is a chemical compound.
Therefore, the answers are Na and C.

What makes plant green ?

What gives plants cells their regular shape ?
Where are the fluids stored in the cell?
What important function does the cell membrane do ?
( can someone help me out please )
Answer:
Chlorophyll makes plants green.
Enzymes are responsible for dictating what chemical changes happen and when, so thus they control the life process of the cells in our bodies.
The cell wall is what gives a plant cell it's distinct shape (animal cells don't have cell walls btw).
Intracellular fluid, or cytosol, is the fluids stored in the Intracellular compartment.
The cell membrane is the barrier between everything inside the cell, and everything else outside of it. It protects the contents of the cell from harm and releases toxins and other waste from it. The cell membrane is basically like the gate keeper of the cell.

In Experiment 1, what volume did the propane gas occupy in the Erlenmeyer flask before the addition of any water?
This question is mentioning an experiment that is not being described about the volume of the propane gas in an Erlenmeyer before the addition of water.
In this case, since no information is given, it is possible to propose a suggested procedure of how to figure it out via gas laws, specifically, the ideal gas one, since no change is decribed before the addition of water:
[tex]PV=nRT[/tex]
Thus, you can solve for the volume, by dividing both sides by the pressure, so that you will get:
[tex]V=\frac{nRT}{P}[/tex]
Now, to ensure a correct calculation, make sure you have the moles (divide by the molar mass of propane, 44,1 g/mol, if you were given the grams), the temperature in K (add 273.15 if you have degree Celsius), the ideas gas constant as 0.08206 and the pressure in atm, in order to have consistent units.
If you need the volume in milliliters, you will need to multiply the previous answer by 1000 in order to perform the appropriate conversion.

Explanation:
what is the main difference between sexual and asexual reproduction
Answer:
Asexual reproduction does not involve sex cells or fertilisation . Only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information.
The main difference between sexual and asexual reproduction is that sexual reproduction involves the fusion of gametes, while asexual reproduction does not.
In sexual reproduction, offspring are produced through the fusion of gametes (reproductive cells) from two parent organisms. This fusion, known as fertilization, results in offspring that inherit genetic material from both parents. This genetic recombination introduces variation in the offspring, promoting genetic diversity within a population.
In contrast, asexual reproduction involves the production of offspring without the involvement of gametes or the fusion of genetic material from two parents. A single parent organism reproduces by generating genetically identical or near-identical offspring through various methods such as budding, fragmentation, or binary fission. Asexual reproduction typically leads to offspring that are genetically identical to the parent, lacking the genetic diversity observed in sexual reproduction.
