The relative humidity shows us saturation of water in air. Since it is 58% and not 100% we have to scale density that we were given when humidity is 100%.

At 100% humidity, density is 20grams/cubic meter

at 58% it will be:
0.58 * 20 = 11.6 g/m^3

Since the question is to find density, the answer cannot be in %.

Answer is 11.6 g/m^3

Consider the reaction cacn2 + 3 h2o → caco3 + 2 nh3 . how much nh3 is produced if 187 g of caco3 are produced? 1. 2.13 mol 2. 63
kodGreya [7K]
Equation is as follow,
   
<span>                               CaCN</span>₂<span> + 3 H</span>₂<span>O   →   CaCO</span>₂<span> + 2 NH</span>₃

According to this equation, 
When,
100 g CaCO₃ (1 mole) is produced when  =  34 g NH₃ (2 moles) is produced
So,
187 g CaCO₃ will be produced then  =  X g of NH₃ will produce

Solving for X,
                                 X  =  (187 g × 34 g) ÷ 100 g

                                 X  =  63.58 g of NH₃ will be produced

Result:
          Option-2 is correct answer.

Tertiary alkyl halides show SN1 reactions mostly...... Why?
ankoles [38]

Answer:

Generally SN1 reactions are carried out in polar protic solvents. The energy required for breaking the C-X bond is obtained through solvation of halide ion with the proton of the solvent. Tertiary alkyl halides undergo SN1 reaction very fast because of the high stability of tertiary carbocations.

A certain second-order reaction (B→products) has a rate constant of 1.30×10−3 M−1⋅s−1 at 27 ∘C and an initial half-life of 224 s
soldier1979 [14.2K]

Answer:

       \large\boxed{\large\boxed{0.291M}}

Explanation:

By definition one <em>half-life</em> is the time to reduce the initial concentration to half.

For a <em>second order reaction </em>the rate law equations are:

              \dfrac{d[B]}{dt}=-k[B]^2

             \dfrac{1}{[B]}=\dfrac{1}{[B]_0}+kt

The <em>half-life</em> equation is:

            t_{1/2}=\dfrac{1}{k[A]_0}

Thus, substitute the<em> rate constant</em>  1.30\times 10^{-3}M^{-1}\cdot s^{-1} and the <em>half-life </em>time <em>224s</em> to find [A]₀:

           224s=\dfrac{1}{1.30\times10^{-3}M^{-1}\cdot s^{-1}[A]_0}

           [A]_o=0.291M
