Elements found in group 1A on the periodic table display Alkali metals. Alkali Metals is your answer.
Answer:
5.59x10^-3 moles
Explanation:
The balanced equation for the reaction is given below:
HCl + KOH —> KCl + H2O
Now we can obtain the number of mole of HCl required to produce 5.59x10^-3 moles of KCl as follow:
From the balanced equation above, 1 mole of HCl produced 1 mole of KCl.
Therefore, 5.59x10^-3 moles of HCl will also produce 5.59x10^-3 moles of KCl.
From the illustration made above, we can see evidently that 5.59x10^-3 moles of HCl is required to produce 5.59x10^-3 moles of KCl

Answer:
According to Hund's rule and the Aufbau principle in which the orbitals must be filled with electrons, they are not strictly applied in the real universe, because the intermediate and electron-filled atomic orbitals are very stable . Because there are four d-orbitals in universe L, a typical half-full configuration will be xd4 and its full configuration will be xd8, where x is the primary orbital for any specific element. Here is an example:
Vahadium ₂₃V
in real universe: [Ar]₈ 3d³4s²
in universe L: [Ar]₁₈ 3d⁴4s¹
Chromium
in real universe: [Ar]₈ 3d⁵4s¹
in universe L: [Ar]₁₈ 3d⁴4s²

Answer:
Option "C" is the correct answer to the following question.
Explanation:
Given:
Pressure in an automobile tire (P) = 1.88 atm
Temperature (K) = 25°C = 273 + 25 = 298 Kelvin
New temperature (K1) = 37°C = 273 + 37 = 310 Kelvin
Find:
New pressure in an automobile tire (P1) = ?
Computation:
![\frac{P}{K}= \frac{P1}{K1} \\\\\frac{1.88}{298}= \frac{P1}{310}\\\\1.9557](https://tex.z-dn.net/?f=%5Cfrac%7BP%7D%7BK%7D%3D%20%5Cfrac%7BP1%7D%7BK1%7D%20%5C%5C%5C%5C%5Cfrac%7B1.88%7D%7B298%7D%3D%20%5Cfrac%7BP1%7D%7B310%7D%5C%5C%5C%5C1.9557)
New pressure in an automobile tire (P1) = 1.9557
New pressure in an automobile tire (P1) = 1.96 (Approx)
