Why do solids maintain their volume and shape? cause-effect
A.) Because they vibrate
B.)because they are packet tight
C.) because they are crystalline
B.)because they are packet tight
Answer:
Because they are packet tight.
Explanation:
Solids maintain their volume and shape because they are packet tight.
A solid's particles fit closely together. The forces between the particles are so strong that the particles can not move freely; they can only vibrate. This causes a solid to be a stable, non-compressible shape with definite volume.Tres diferencias entre los líquidos y los sólidos
Answer: Density, Volume, Shape
why does pure water not conduct electricity in terms of bonding
[tex] \huge\begin{gathered} {\underline{\boxed{ \mathcal {\red{Answer}}}}}\end{gathered}[/tex]
Positive and negative ions attract each other and combine with each other to yield ionic compounds and they are separated easily to conduct electricity.
The concentration of ions in pure water is very less and is almost unionised, thus does not conduct electricity.The density of gold is 19.3 g/cm³. What is the mass of 11.3 cm³ of gold?
Answer:
218.09g
Explanation:
the formula for density is mass/volume
you have volume so rlly what you have is 19.3g/cm3=m/11.3cm3
so mass equals density x volume
and 19.3 x 11.3 = 218.09

which element on the periodic table has the highest electronegativity
Answer:
fluorine
Explanation:
Electronegativity varies in a predictable way across the periodic table. Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative
What does mean when it asks for the smaller ion
Explanation:
mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus.

Carbon can form large number of organic compounds why
Answer:
Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

Find the number of protons, neutrons, and electrons for carbon-12, carbon-13, and carbon-14 respectively.
Answer:
A neutral atom of Carbon-12 contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 (six protons plus six neutrons).
Carbon-13 (13C) is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons and six electrons.
Neutral carbon-14 contains six protons, eight neutrons, and six electrons; its mass number is 14 (six protons plus eight neutrons).
Hope this helps! =D
The number of electrons, protons and neutrons in carbon -12 are all 6 and in carbon-13 they are 6, 6, and 7 respectively and in carbon-14 it is 6, 6,and 8 .
What are isotopes ?Isotopes are atoms of same element with different mass numbers. Isotopes slightly differ in physical and chemical properties also. Most of the element in periodic table have isotopes however, not all of them are stable and abundant.
The number electrons and protons in a neutral atom is equal. Mass number of an atom is the sum of number of protons and neutrons. In carbon -12, the number of electrons and protons and neutrons is 6 and the number of neutrons in carbon -13 is 7.
The number of electrons and protons is 6 and that of carbon- 14 is 7. Therefore, all these isotopes are having same atomic number but differ in neutrons numbers.

which molecule is a common output of glycolysis, pyruvate oxidation, and the citric acid cycle?
Explanation:
Acetyl CoA links glycolysis and pyruvate oxidation with the citric acid cycle. In the presence of oxygen, acetyl CoA delivers its acetyl group to a four-carbon molecule, oxaloacetate, to form citrate, a six-carbon molecule with three carboxyl groups.
Acetyl Co-A is a common output of glycolysis, pyruvate oxidation and citric acid cycle.
How does acetyl co-A links glycolysis and citric acid cycle?Acetyl Co-A links glycolysis and pyruvate oxidation with the citric acid cycle as in presence of oxygen it delivers its acetyl group to four carbon molecule to form citrate a six carbon molecule with three carboxyl groups .
In the citric acid cycle, 2 carbons of acetyl group which were of acetyl Co-A are released in form of carbon dioxide a major product of cellular respiration. For each acetyl Co-A which enters citric acid cycle 2 carbon dioxide molecules are released.
The transition reaction is the conversion of 3-carbon pyruvate to 2- carbon acetyl co-A and 2 molecules of carbon dioxide.

Let required moles be x
[tex]\\ \sf\longmapsto \dfrac{2}{6}=\dfrac{x}{75}[/tex]
[tex]\\ \sf\longmapsto \dfrac{1}{3}=\dfrac{x}{75}[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{75}{3}[/tex]
[tex]\\ \sf\longmapsto x=25mol[/tex]
2moles of H2O are made when 6moles of HNO3 are consumed
75 mole of HNO3 produces = [tex]\frac{2}{6}[/tex]× 75 ⇒ 25 moles of water
Limiting Reagent MethodThe limiting reagent is the reactant that is completely used up in a reaction and thus determines when the reaction stops.
S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O
6 mole of HNO3 produces = 2 moles of H₂O
1 mole of HNO3 produces = [tex]\frac{2}{6}[/tex] mole of H₂O

B XY
C

Answer:
Its formula is B) XY3,also known as ammonia,because X is hydrogen and Y is nitrogen.
So,yeah the answer is B
Pls mark me as brainliest
The electronic structures of atoms X and Y are shown. X and Y form a covalent compound. The formula is XY₃. The correct option is B.
What are covalent bonds?Covalent bonds are the strongest bonds present between chemical elements. This bond is formed by sharing electrons between the elements.
Two atoms share electrons with each other and form bonds between them. They are the strongest because there is sharing of electrons between them.
There are five electrons present in the outer shell of the Y atom. There are two atoms more needed to complete the orbital of Y. There is one electron present in the X atom.
Those compounds that are formed by the covalent bond are the strongest compounds. So they are not easy to break them.
Thus, the correct option is B. XY₃.
