A weight of 8.7 N is attached to a spring that has a spring constant of 190 N/m. How much will the spring stretch?
Answers
Fs=8.7N
K=190N/m
Unkown:
X=?
Equation:
Fs=Kx
8.7N=(190N/m)x
X=4.6*10power of-2m
Given values are:
Force, Fs = 8.7 NSpring constant, k = 190 N/mAs we know the relation,
→ [tex]Fs = K\times x[/tex]
or,
→ [tex]x = \frac{Fs}{k}[/tex]
By putting the values, we get
[tex]= \frac{8.7}{190}[/tex]
[tex]= 4.6\times 10^{-2} \ m[/tex]
Thus the response above is right.

(Help would be greatly appreciated, chemistry is not my strong suit) How many moles of NaCl are present in a solution with a molarity of 8.59M and 125mL of a solution?
1. 1.07g
2. 62.7mol
3. 1.07mol
4. 62.7g
Answers
Molarity is a unit of concentration defined as the number of moles of solute (the substance being dissolved) per volume of solution (the solvent in which all the solute is dissolved). Mathematically, molarity is expressed as
[tex]M = \frac{\text{ mol solute}}{\text{ L solution}}[/tex].
In this question, we are given the molarity and the volume of a solution of NaCl. We can use this information to calculate the number of moles of NaCl present in the solution. Rearranging the equation to solve for moles of solute, we multiply the molarity by the volume of the solution (the units for volume must be in liters, so 125 mL is expressed as the equivalent 0.125 L):
[tex](8.59 \text{ M})(0.125 \text{ L}) = 1.07 \text{ moles of NaCl}.[/tex]
The question asks for the number of moles of NaCl in this solution, so number 3 would be correct.

Why is fluorine a gas at room temperature?
GIVING BRAINLIEST AND LOTS OF POINTS ‼️‼️
Answers
Answer:
In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.

How many grams of Sulfur are there in 2.05 x 10^25 molecules of Calcium Sulfate?
Answers
Answer:
1090 grams Sulfur (3 sig-figs)
Explanation:
Given 2.05 x 10²⁵ molecules CaSO₄ => 2.05 x 10²⁵ Sulfur atoms (subscript = 1 mole).
Converting 2.05 x 10²⁵ sulfur atoms to moles, divide by Avogadro's Number
(= 6.023 x 10²³ sulfur atoms / mole sulfur) => 2.05 x 10²⁵ sulfur atoms/6.023 x 10²³ sulfur atoms/mole sulfur atoms = 34.036 moles sulfur atoms.
Converting 34.036 moles sulfur to grams sulfur multiply by formula wt. of sulfur (=32g/mole S)
=> 34.036moles S x 32g/mole S = 1089.158 grams S ≅ 1090 g S (3 sig-figs)

An atom of an element always contains a proton, electron and neutron.
What is an atom ?Every atom is made up of a nucleus and one or more electrons that are attached to the nucleus. One or more protons and a number of neutrons make up the nucleus. Only the most common type of hydrogen is neutron-free. Every solid, liquid, gas, and plasma is made up of atoms that are either neutral or ionized.
But when it comes to the word atom, we must go back to 400 B.C. Greece. And Democritus, a brilliant philosopher, proposed the Greek word atomos, which means uncuttable.

On the periodic table, what is a group? For the main groups, what characteristic
do the elements have in common?
Answers
Answer:
The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Explanation:
On the periodic table, a group refers to a vertical column of elements that share similar chemical properties.
For the main groups, the characteristic do the elements have in common is valence electron configuration and chemical reactivity.
On the periodic table, a group refers to a vertical column of elements that share similar chemical properties. These elements are arranged in such a way that they have the same number of valence electrons, which are the electrons in the outermost energy level (shell) of their atoms. The number of valence electrons is a critical factor in determining the chemical behavior and reactivity of elements, as it governs their ability to form chemical bonds with other elements.
Main group elements, also known as representative elements, are located in the s-block and p-block of the periodic table. These elements are found in Groups 1, 2, and 13 to 18. Each main group is labeled with a number from 1 to 18.
Here are the main characteristics that elements in the same main group (vertical column) have in common:
1. Valence Electron Configuration: Elements in the same main group have identical valence electron configurations. For example, elements in Group 1 (alkali metals) all have one valence electron in their outermost energy level (ns¹), while elements in Group 18 (noble gases) have a full outermost energy level.
2. Chemical Reactivity: Due to their identical valence electron configuration, elements in the same group show similar chemical reactivity. They tend to form similar types of chemical bonds and react similarly with other elements to achieve a more stable electron configuration.
3. Periodic Trends: Main group elements within a group exhibit predictable trends in their physical and chemical properties as you move from the top to the bottom of the group. For example, the atomic radius tends to increase, ionization energy tends to decrease, and metallic character tends to increase as you go down a group.
