What happens when ammonia reacts with Thiosulfate?
When ammonia reacts with thiosulfate, it forms an amine complex known as [N(NH3)4]+, resulting in the liberation of sulfur dioxide gas. This reaction is typically employed in qualitative analysis to detect the presence of thiosulfate ions.
How do you make 0.05Normality of sodium thio sulphate?
To prepare a 0.05 Normal solution of sodium thiosulfate, you would dissolve the appropriate weight of sodium thiosulfate pentahydrate in a known volume of water to achieve a concentration that corresponds to 0.05 N. The molar mass of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) is 248.18 g/mol. You can calculate the weight needed using the formula: (Normality) x (Equivalent weight) x Volume = Weight of the compound.
What equation shows how rate depends on concentrations of reactions?
The equation is called the rate law equation. For the reaction aA+bB =>cC+dD the rate law would be rate = k[A]^m[B]^n where k is the rate constant and m and n are the "order" with respect to each reactant. m and n must be determined experimentally and may or may not be the same as the coefficients a and b.
What is the rate constant of a reaction if rate 1 10 2 mol L s A is 2 M B is 3 M m 2 and n 1?
The rate law for this reaction is rate = k[A]^m[B]^n. From the given information, substituting the values for rate, [A], [B], and the exponents m and n, you can solve for the rate constant k. In this case, k = rate / ([A]^m[B]^n), so k = 2 / (10^2 * 3^1).
What is the formula for percent of concentration?
M = n / V M = concentration of solution in mol/L, n = moles of substance, V = volume of solution in litres (L) the formula can re-arranged to V = n / M :)
When did M. N. Roy die?
M. N. Roy was born on 1886-03-21.
What is the rule for multiplying powers with the same base and dividing power with the same base?
When multiplying powers with the same base, you add the exponents: (a^m \times a^n = a^{m+n}). Conversely, when dividing powers with the same base, you subtract the exponents: (a^m \div a^n = a^{m-n}). This rule applies as long as the base (a) is not zero.
What happens when ammonia reacts with Thiosulfate?
When ammonia reacts with thiosulfate, it forms an amine complex known as [N(NH3)4]+, resulting in the liberation of sulfur dioxide gas. This reaction is typically employed in qualitative analysis to detect the presence of thiosulfate ions.
What happens when 2 numbers with the same base are divided?
When two numbers with the same base are divided, their exponents are subtracted. This is expressed mathematically as ( a^m / a^n = a^{m-n} ), where ( a ) is the base and ( m ) and ( n ) are the exponents of the respective numbers. The result will be a new number with the same base raised to the difference of the exponents. If ( m < n ), the result will be a fraction.
What is the relationship between the values m ad n plotted on the number line below?
To determine the relationship between the values ( m ) and ( n ) plotted on a number line, you would compare their positions. If ( m ) is to the left of ( n ), then ( m < n ); if ( m ) is to the right of ( n ), then ( m > n ); and if they are at the same point, then ( m = n ). The specific relationship depends on their respective placements on the number line.
When was M. N. Abdul Majeed born?
Abdulrahman Mohammed Jamsheer was born in 1944.
Can you prove mathematically that a geometric random variable possesses the so called Memory-less property?
Proof: P{T>n+m/T>n}=P{T>n+m,T>n}/P{T>n} (Bayes theorem) =P{T>n+m}/P{T>n} =((1-p)^(n+m))/(1-p)^n = (1-p)^(n+m-n) = (1-p)^m (1-p)^m = {T>m} So T>m has the same probability as T>m+n given that T>n, which means it doesn't care (or don't remember) that n phases had passed.
Where m and n are statements m n is called the of m and n?
Where m and n are statements m n is called the _____ of m and n.
How do you prepare N 80 thiosulphate?
To prepare N 80 thiosulfate, dissolve 80 grams of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in enough distilled water to make a final volume of 1 liter. Stir the solution until the thiosulfate is completely dissolved. Ensure that the solution is mixed well and store it in a properly labeled container. Always follow safety protocols when handling chemicals.
What is a square matrix?
Square Matrix: When m=n (Here m=Rows and n=colums) are same is called square matrix. Ex. A=|Bij|
Why do we add exponents when we multiply terms with the same base?
When multiplying terms with the same base, we add the exponents because of the fundamental property of exponents that states (a^m \times a^n = a^{m+n}). This property arises from the repeated multiplication of the base: for example, (a^m) represents multiplying the base (a) by itself (m) times, and (a^n) represents multiplying it (n) times. Therefore, when these two terms are multiplied, the total number of times the base (a) is multiplied is (m + n).
What is m plus N plus p equals p plus n plus m?
It would be the same number either way because its addition.
