Answer:

246.67 min

Explanation:

Half life is the time at which the concentration of the reactant reduced to half.

Half life expression for first order kinetic is:

t_{1/2}=\frac {ln\ 2}{k}

Where, k is rate constant

So,  

Given that;- k = 2.81\times 10^{-3}\ min^{-1} (Values corrected from source)

Thus,

t_{1/2}=\frac{\ln2}{2.81\times 10^{-3}\ min^{-1}}=\frac{\ln2}{2.81\times 10^{-3}}\ min

t_{1/2}==355.87188\ln \left(2\right)\ min=246.67\ min

<u>246.67 min is the half-life of the reaction.</u>

Answer:

t(1/2) = 246.67 min

Explanation:

a: SO2Cl2

⇒ - ra = k(Ca)∧α = - δCa/δt

∴ k = 2.81 E-3 min-1

∴ α = 1

⇒ Ln(Cao/Ca) = k*t

half-life of the reaction:

∴ Ca = (1/2)Cao

⇒ Ln (2) = (2.81 E-3 min-1)*t

⇒ t (1/2) = ( 0.6931 ) / ( 2.81 E-3 min-1 )

⇒ t (1/2) = 246.67 min

Name the four elements on the Periodic Table that are considered METALLOIDS?​
Nimfa-mama [501]

Answer:

boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At)

Explanation:

metalloids are elements that are in between the metals and nonmetals. they are in between because they have properties of both metals and nonmetals.

you can search "metalloids on the periodic table" and go to images to see what i mean :)

A mineral consisted of 29.4% calcium, 23.5% sulfur and 47.1% oxygen. What is the empirical formula?
inessss [21]
Step  one  calculate  the  moles  of  each  element
that  is  moles= %  composition/molar  mass
molar  mass  of    Ca  =  40g/mol,     S=  32  g/mol ,   O=  16 g/mol

moles  of      Ca = 29.4 /40g/mol=0.735 moles,      S= 23.5/32  =0.734 moles,  O= 47.1/16= 2.94   moles

calculate  the mole  ratio  by  dividing   each  mole with  smallest  mole   that   is  0.734
Ca=  0.735/0.734= 1,      S=  0.734/0.734 =1,   O  = 2.94/  0.734= 4
therefore  the  emipical  formula  =  CaSO4
