Both assertion and reason are correct and reason is the correct explanation of assertion. Concentration of ionic solution CHANGES on using DC current as a source of energy while on PASSING AC current concentration does not change Hence AC source is USED for MEASURING RESISTANCES.

The PH of N/10 SODIUM HYDROXIDE is 13.

CnH2n+2 is the FORMULA EXPLANATION:if n=2 Then C2H2(2)+2C2H6 is CORRECT

The RATE of REACTION is ZERO -degreeExplanation:In some reactions, the rate is apparently independent of the reactant concentration. The RATES of these zero-order reactions do not vary with increasing nor decreasing reactants concentrations. This means that the rate of the reaction is equal to the rate constant, k, of that reaction

for seven POINT everyone gives me only FIVE POINTS thank u very MUCH

re option (b) is correct choice.Given : If limiting MOLAR CONDUCTIVITY of Ca²⁺ and Cl¯ are 119.0 and 76.3 S cm² MOL¯¹. To find : The value of limiting molar conductivity of CaCl₂. solution : from Kohlrausch's law, ⇒ = 119 + 2 × 76.3 = 119 + 152.6 = 271.6 cm²mol¯¹ The limiting molar conductivity of CaCl₂ is 271.6 cm²mol¯¹Therefore option (b) is correct choice.also read SIMILAR questions : The molar conductivity of 0.025 mol L−1 methanoic acid is 46.1 S cm2 mol−1 . brainly.in/question/5247791From the following molar conductivities at infinite dilution,Am for Al2(SO4)3 = 858 S cm2 mol-'An for NH,OH = 238.3... brainly.in/question/10255022

it under GOES THERMAL decomposition REACTION Explanation:thermal decomposition REACTIONS takes place as they ABSORB heat

X = CaO ( QUICK LIME)Y = Ca(OH)2 (Slaked lime)Z = CACO3. ( Calcium Carbonate)(i) Ca + O2 ➡️ CaO(ii). CaO + H2O ➡️ Ca(OH)2 + heat(iii). Ca(OH)2 + CO2➡️ CaCO3 + heat

IN WHICH THING  CAN I HELP YOU ........................EXPLANATION:

4.74Explanation:325 GRAMS of Barium is:325/137 = 2.37 molesBecause barium is in GROUP 2 DOUBLE the moles of Lithium MUST be in the COMPOUND, so 2.37 * 2 = 4.74 moles

When the magnesium metal burns it reacts with oxygen found in the air to FORM Magnesium OXIDE. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical REACTION to form this compound.MARK ME AS BRAINLIEST IF YOU FIND THIS HELPFUL :)

ve formula infers that osmotic PRESSURE is DIRECTLY proportional to factors such as CONCENTRATION, gas constant and temperature. THUS it is inferred that as osmotic pressure is directly proportional to temperature INCREASES with increase in temperature and decreases with decrease in temperature.

,I = no. of MOLECULE after association / no. of molecule before association.Now,in CASE of association ,NUMBER of molecule after the reaction will be lesser.hence, i < 1.Also, I > 0.Hence, in case of association , 0< i < 1

Osmotic PRESSURE of 1 m higher than 1 m UREA solution as osmotic pressure is a colligative property which depends on the amount of solute. being a electrolyte, it dissociate into ions in aqueous solution whereas urea does not. Thus the number of moles will be more on ADDITION of KCl and lesser number of moles on addition of urea(π)=CRT (π= osmotic pressureC= concentrationR= solution constantT= temperaturemark as brainliest

In the DETERMINATION of molar mass of A+B- using a colligative property, what MAY be value of van't Hoff factor if the SOLUTE is 50% dissociated? Solution : α=i-1n-1⇒0.5=i-12-1⇒i=1.5.
