Answer:oxidation number H = +1
oxidation number O = -2
let x = oxidation number Cl
in HClO3
+1 + x -6 =0
x = +5
Explanation:
The Molarity of solution that contain 2.3 mole of NaCl in 0.45L of solution is calculated using the below equation
= molarity = moles/volume in liters
= 2.3 moles/0.45 L = 5.1 M
Answer is D - Argon atom
Potassium has atomic number as 19. Hence, number of protons = 19
If the atom is neutral,
number of protons = number of electrons = 19
Hence, the electron configuration of potassium (K) is
1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹
Potassium ion is formed by losing an electron. Then the number of electrons = 19 - 1 = 18
Electron configuration of K⁺ is 1s² 2s² 2p⁶ 3s² 3p⁶.
This is same as the electron configuration of Ar which has 18 electrons.
Kinetic energy is KE=0.5mv^2
Since the car is mass is the smallest efor the three situations
the Kinetic energy at 30 mph
KE1=0.5 m (30)^2
the Kinetic energy at 15 mph
KE2=0.5 m(15)^2
the Kinetic energy at 0 mph
KE3=0
KE1>KE2
The Kinetic energy at 30 mph is the highest
