Answer:

2x1000 = 2000

Explanation:

10^3 = 10×10×10 = 1000

exponent , the ^3 means multiply the number by itself 3 times, if it was ^4, it would be 4 times and so forth.

another trick for 10s is just put the 1 and the exponents number of 0's after the 1. so in this case, put three 0's: 1,000

Answer: 2000 or 2000.00 in decimal form if you need

Explanation: Real number to turn Scientific to Real Number you must type the exact scientific notation into a scientific calculator including the Times symbol and it should convert it In other words Multiply the decimal number by 10 raised to the power indicated. Ex: 3.456 x 10^4 = 3.456 x 10,000 = 34560

Calculate the Ka for the following acid. Determine if it is a strong or weak acid. HClO2(aq) dissolves in aqueous solution to fo
Talja [164]

Answer:

The value of Ka = 1.1*10^{-2}

It is a weak  acid

Explanation:

   From the question we are told that

             The concentration of [HClO_2]=0.24M

             The concentration of  [H^+]=0.051M

             The concentration of  [ClO_2^-]=0.051M

Generally the equation for the ionic dissociation of HClO_2 is

                HClO_2_(aq) -------> H^{+}_{(aq)} + ClO_2^{-}_{(aq)}

The equilibrium constant is mathematically represented as

                         Ka = \frac{concentration  \ of  \ product  }{concentration \ of \  reactant }

                               = \frac{[H^+][ClO_2^-]}{[HClO_2]}

Substituting values since all value of concentration are at equilibrium

                    Ka = \frac{0.051 * 0.051}{0.24}

                          = 1.1*10^{-2}

Since the value of  is less than 1 it show that in water it dose not completely

disassociated  so it an acid that is weak
