Answer:
0.09 M/s is the initial rate when concentration of reactant A is 0.900 M.
Explanation:
A → B
1) Initial concentration of A = [A] =0.300 M
Rate constant of the reaction , k = ?
Rate equation for the second order kinetic is given as:
2) Rate of the reaction when initial concentration of A was 0.900M be R'.
[A] = 0.900M
Trigonal planar is the three-dimensional shape of the molecule with this Lewis structure. Hence, option C is correct.
Lewis dot structures also called electron dot structures are diagrams that describe the chemical bonding between atoms in a molecule.
According to the Lewis structure of formic acid, the carbon atom is a central atom and it has three bond pairs without any lone pair of electrons. In VSEPR theory, the double bond is treated as one bond pair for the prediction of the shape of the molecule.
Hence, formic acid will have a trigonal planar geometry around the carbon atom and tetrahedral geometry around oxygen atom as it has two lone pair and two bond pairs
Hence, option B is correct.

b. AlCl2 + 2Cs yields 2CsCl + Al
c. AlCl3 + 3Cs yields 3CsCl + Al
d. 2AlCl3 + 6Cs yields 2AlCs3 + 3Cl2
Answer is C.
Explanation;
Single replacementreaction is a chemical reaction between an element and a compound. Theelement takes the position of another element in the compound by replacing.
Common equation is
A + BC → AC + B
Al is in 13th group ofthe periodic table. Hence, Al forms Al³⁺ by losing 3 electrons.Likewise, Cl is in 17th group of the periodic table and forms Cl⁻ by gaining one electron. Hence aluminiumchloride can be written as AlCl₃.
Cs is in 1st group ofthe periodic table. Hence, Cs tends to form Cs⁺ by losing an electron.
The reaction between Cs⁺ and Cl⁻ will form CsCl.
Since, this is a single replacement reaction, Al inthe AlCl₃ is replaced by Cs andCsCl is formed. The balancedreaction equation is
AlCl₃ + 3Cs → 3CsCl + Al
Answer:
(NH4)2CO3(s) → 2 NH3(g) + CO2(g) + H2O(g)
Explanation:
The balanced equation can be written when we know the chemical formula of each reactants and products of the reaction.
Ammonium carbonate = (NH4)2CO3(s)
Ammonia = NH3(g)
carbondioxide = CO2(g)
water = H2O(g)
The ammonium carbonate was decomposed in the reaction , so ,
(NH4)2CO3(s) → NH3(g) + CO2(g) + H2O(g)
The reactant is on the left side while the product is on the right side. Let us balance the equation to make sure every atom of element is same number on both sides of the equation.
(NH4)2CO3(s) → 2 NH3(g) + CO2(g) + H2O(g)
The decomposition of ammonium carbonate upon heating produces ammonia, carbon dioxide, and water. The balanced equation for this decomposition reaction is: (NH4)(HCO3) → NH3 + CO2 + H2O.
The decomposition of solid ammonium carbonate (NH4)(HCO3) upon heating produces ammonia (NH3), carbon dioxide (CO2), and water (H2O) in gas form. This is a specific type of reaction called a decomposition reaction, which breaks down a compound into its constituent parts. The balanced chemical equation informing this process is: (NH4)(HCO3) → NH3 + CO2 + H2O.
Note from this equation, it is clear that the ammonium carbonate completely disappears as it gets converted into gaseous products upon heating.

The electron affinity of an atom or molecule is defined as electricity launched when electrons are introduced to the outermost shell. Electron affinity increases from left to right across a length.
Electronegativity is described because the tendency of an atom attracts the bonded pair of electrons of covalent bond to itself. To a degree, the electronegativity Pauling scale is used.
