Answer:

actually answer should be helium

Answer:

Fluorine

Explanation:

Fluorine has an atomic number of 9

Iron's is 26

Phosphorus = 15

Potassium = 19

Fluorine has the smallest number of protons, and as it is an atom, the number of protons = the number of electrons. As it has less electrons, it only has 2 shells, whereas all the other elements here have 3+ shells. This means it will have a smaller atomic radius than them.

Hope this helps! Let me know if you have any questions :)

A heat energy of 645 J is applied to a sample of glass with a mass of 28.4 g. Its temperature increases from –11.6 ∞C to 15.5 ∞C
Anika [276]
The heat that is required to raise the temperature of an object is calculated through the equation,
                        heat = mass x specific heat x (T2 - T1)
Specific heat is therefore calculated through the equation below,
                                specific heat = heat / (mass x (T2 - T1))
Substituting,
                                specific heat = 645 J / ((28.4 g)(15.5 - - 11.6))
The value of specific heat from above equation is 0.838 J/g°C.

Calcuate the number of<br> grams of solute in 453.9mL<br> of 0.237 M calcium acetate
AysviL [449]

The number of  grams : 17.082 g

<h3>Further explanation</h3>

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

\large {\boxed {\bold {M ~ = ~ \dfrac {n} {V}}}

Where

M = Molarity

n = Number of moles of solute

V = Volume of solution

453.9 mL  of 0.237 M calcium acetate

  • mol

\tt mol=M\times V=0.237\times 0.4539=0.108

  • mass

MW Ca(C₂H₃OO)₂ : 158,17 g/mol

\tt mass=mol\times MW\\\\mass=0.108\times 158.17=17.082~g

Explain how transverse waves can be produced on a rope. Then describe how pieces of the rope move as waves pass.
andrew-mc [135]
Transverse waves can be produced on a rope by moving one end of the rope up and down.The movement causes motion in the particles that make up the rope and the rope itself becomes the medium. The particles move perpendicular to the propagation. The movement also causes crests(highest point of the wave) and troughs (lowest point of the wave) which move along the direction of propagation.
