Also water H2O is made of H+ and OH- ions. so when an acidic substance is added to water the concentration of H+ ions increase.
Answer:
98.6 g/mol.
Explanation:
Equation of the reaction
HX + NaOH--> NaX + H2O
Number of moles = molar concentration × volume
= 0.095 × 0.03
= 0.00285 moles
By stoichiometry, 1 mole of HX reacted with 1 mole of NaOH. Therefore, number of moles of HX = 0.00285 moles.
Molar mass = mass ÷ number of moles
= 0.281 ÷ 0.00285
= 98.6 g/mol.
The answer is false..............<span>kinetic theory of gases is a topic that can explain many everyday observations. Have you ever wondered why water boils faster at higher altitudes? Or why inflatable pool toys seem flat after sitting in a cold garage? How about why you can smell a candle all throughout the house? All of these phenomena and many more can be explained by the kinetic theory of gases.</span>
Answer:
<em>The correct option is C) Very low</em>
Explanation:
In physics, resistance can be described as the opposition to the flow of current or the flow of electrons. Conductors are known to be materials which can conduct electricity. Hence, conductivity and resistance are opposite to each other. Good conductors will have very little or no resistance and will have enhanced conductivity. On the contrary, insulators are materials which will have more resistance and they cannot conduct electricity as efficiently.
<h3>Answer:</h3>
Br (Bromine)
<h3>Explanation:</h3>
Li and K,
As the electronegativity difference between Li and K is less than 1.7 therefore, ionic bond cannot form between these two metals.
Li and Fe,
The electronegativity difference is less than 1.7 so neither electron loss nor electron gaining will take place between these two metals. Therefore, there will be no ionic bond between them.
Li and Kr,
As Krypton is a noble gas and does not react due to complete octet hence the formation of KrLi is difficult. However, Krypton can make compounds like KrF₂ e.t.c. Therefore we can skip this option.
For Li and K,
E.N of Bromine = 2.96
E.N of Lithium = 0.98
________
E.N Difference 1.98 (Ionic)
This ionic compound is possible and is the correct option because ionic compounds are always made by metals and non metals and here the combination is perfect.
<h3>Conclusion:</h3>
Lithium (a metal) and form Ionic bond with Bromine (a non metal)
