Which statement best describes the charges of the particles involved?
(1 point)
O A neutral particle is striking a positive particle, breaking it into more
O A negative particle is striking a positive particle, breaking it into mor
O A positive particle is striking a neutral particle, breaking it into more
O A neutral particle is striking a negative particle, breaking it into more
The statement that best describes the charges of the particles is : ( A ) A neutral particle is striking a positive particle, breaking it into more
Production of Negative and Positive particlesThe collision of Neutral and postitve particles leads to the production of more negative and positive particles. Due to the neutral force and this leads to the production of an electrical charges.
Hence a neutral particle striking a positive particle will lead to the production of more positive particle.

50. Arrange the following pairs from strongest to weakest
attraction:
a. polar molecule and polar molecule
b. nonpolar molecule and nonpolar molecule
C. polar molecule and ion
d. ion and ion
Arranging the pairs from strongest to weakest attraction :
Nonpolar molecule and Nonpolar molecule ( B )Polar molecule and Polar molecule ( A )Polar molecule and Ion ( C )Ion and Ion ( D )Covalent bonds are the strongest bonds because it involves the sharing of electrons between two binding atoms therefore the atoms are not dissociated easily. Also covalent bonds are divided into ;
Polar covalent bonds ; The shared electrons from each atom involved are unequal therefore it is easier to dissociate polar molecule bonds ( i.e. weaker bond ). Non Polar covalent bonds ; The shared electrons from each atoms are equally therefore it is harder to dissociate nonpolar molecule bonds ( i.e. stronger bond when compared to polar bonds ).While Ionic bonds involves the transfer of electrons from a donor atom to another atom and such bonds are easily broken and it is a weaker bond when compared to Polar and Nonpolar bonds. therefore polar molecule and ion bond pair is stronger than ion and ion pair.
Hence we can conclude that ranking the pairs from strongest to weakest attraction is as follows; Nonpolar molecule and Nonpolar molecule, Polar molecule and Polar molecule, Polar molecule and Ion, Ion and Ion.

Is carbon mixed with sand a homogeneous or heterogeneous mixture
Answer:
homogeneous
Explanation:
because I said so
A carbon mixed with sand is a heterogenous mixture.
What is heterogenous mixture?
Mixture is defined as a combination to two or more simpler substances.
There are two types of mixture
Homogenous mixture - A homogenous mixture is defined as a mixture of two or more component which is uniform throughout the mixture. They include water, air, steel etc.Heterogenous mixture - A heterogenous mixture is defined as a mixture of two or more phase which is not uniform throughout the mixture. They include sand and water, salt and oil etc. They are a non uniform mixture with visible or invisible particles.Thus, carbon mixed with sand is a heterogenous mixture.

Rocks can be classified based on texture. The size of the grains in a rock affects its texture. Coarse-grained rocks have large grains, and fine-grained rocks have small grains.
Rocks formed from magma under Earth’s surface have larger grains than rocks formed from lava on Earth’s surface. This is because magma cools slower underneath the ground than it does above ground.
What kind of rock is this?
A.Igneous
B.Metamorphic
C.Sedimentary
Where would this rock most likely be formed?
A. Along the sides of a volcano
B. On the ocean floor"
C.underneath the Earths surfaces
To which group of rocks would this rock belong?
A. Coarsed-Grained Rocks
B. Fine-Grained Rocks
C. Non-Grained Rocks
1. is Igneous rock
2. is underneath Earths surface
3. is Coarsed-grained

The kind of rocks is igneous rocks formed along the sides of volcano and are coarsed-grain rocks.
What are igneous rocks?
Igneous rocks are one of the three main rock types the other two including sedimentary and metamorphic rocks.These rocks are formed by cooling and solidification of lava or magma.
The magma is derived from partial melts in the planet's mantle or crust.Melting is caused by increase in temperature or decrease in pressure or even change in composition.Solidification occurs either below surface which is called as intrusive rocks or on the surface as extrusive rocks.
They are classified according to their texture,mode of occurrence,chemical composition,geometry and mineralogy of rock.The two important variables for classification are mineral composition and cooling history.

at 20°c, a 0.376 m aqueous solution of ammonium chloride has a density of 1.0045 g/ml. what is the mass % of ammonium chloride in the solution? the formula weight of nh4cl is 53.50 g/ml.
At 20°c, a 0.376 m aqueous solution of ammonium chloride has a density of 1.0045 g/ml. The mass percent of the ammonium chloride in the solution is 2.003%.
The number of moles of a substance can be estimated as:
[tex]\mathbf{number\ of\ moles = \dfrac{mass}{molar \ mass}}[/tex]
Given that:
number of moles = 0.376 Mmolar mass of ammonium chloride = 53.50 g/mlMass = number of moles × molar mass
Mass = 0.376 × 53.50
Mass = 20.116 grams
In one mL of ammonium chloride; the grams of ammonium chloride is:
[tex]\mathbf{= \dfrac{20.116 \ grams}{1000 \ mL}}[/tex]
= 0.020116 g/mL
The mass of ammonium chloride in the solution can be computed as:
[tex]\mathbf{=(\dfrac{mass \ of \ NH_4Cl}{density \ of \ the \ solution})\times 100}[/tex]
[tex]\mathbf{=(\dfrac{0.020116 }{1.0045})\times 100}[/tex]
= 2.003%
Therefore, we can conclude that the mass percent of the ammonium chloride in the solution is 2.003%.

Answer:
Explanation:Compounds between Nonmetals and Nonmetals
Compounds that consist of a nonmetal bonded to a nonmetal are commonly known as Molecular Compounds, where the element with the positive oxidation state is written first. In many cases, nonmetals form more than one binary compound, so prefixes are used to distinguish them.

what is the end-product of the beta-amylase reaction?
Answer:
maltose
Explanation:
β-amylase is an enzyme found in fungi, bacteria and plants but not in humans. Unlike α-amylase, β-amylase can only degrade starch from the non-reducing end of the polymer chain by hydrolysis of the second α-1,4 glycosidic bond. The end product is thus maltose, i.e. two glucose units.
what do an atom ion and isotope of an element have in common?
An atom ion and isotope of an element have in common that both have the same number of protons but they have different numbers of neutrons.
WHAT IS AN ION AND ISOTOPE?An ion is a charged atom while an isotope is the atoms of an element with the same atomic number but different atomic mass.
For example; Mg2+ is the ionic form of Magnesium while C-12 and C-14 are isotopes of carbon.
Here the ion of an atom will have a different charge but the same mass.
Also The isotope of an atom will have a different mass.
The number of protons V/S the more general atom, an ion has a different number of electrons, and an isotope, a different number of neutrons.
Hence atom ion and isotope of an element have in common that both have the same number of protons but they have different numbers of neutrons.
