JulsSmile [24]3 years ago
7 0

Answer:

1. → D, 2.→ A, 3. → B, 4. → C.

Explanation:

1.  Na^+ + Cl^- \rightarrow NaCl

Synthesis reaction is a type of chemical reaction in which two more reactants combines together to form a single product.

2. CCl_4\rightarrow C + 2Cl_2

Decomposition reaction is a type of chemical reaction in which a single compound break down into its constituting elements.

3. H^+Cl^- + Na^+OH^-\rightarrow Na^+Cl^- + H_2O

Exchange reaction is a type of chemical reaction in which ions of reactant exchange their respective position with each other to form a new substance as a product.

4. ADP + P + E → ATP

Reversible reaction is a type of chemical reaction which reversed. In this reactants on reaction gives products and when products are made to react gives reactant as product.

Explain why lithium is a strong reducing agent, whereas fluorine is a strong oxidizing agent.
Tom [10]
Lithium is a good reducing agent because it is electropositive [it rapidly gains electrons]
fluorine is  good oxidizing agent electronegative [it loses electrons fastly]

A bomb calorimeter has a heat capacity of 783 J/oC and contains 254 g of water whose specific heat capacity is 4.184 J/goC. How
IrinaK [193]

Answer : The amount of heat evolved by a reaction is, 4.81 kJ

Explanation :

Heat released by the reaction = Heat absorbed by the calorimeter + Heat absorbed by the water

q=[q_1+q_2]

q=[c_1\times \Delta T+m_2\times c_2\times \Delta T]

where,

q = heat released by the reaction

q_1 = heat absorbed by the calorimeter

q_2 = heat absorbed by the water

c_1 = specific heat of calorimeter = 783J/^oC

c_2 = specific heat of water = 4.184J/g^oC

m_2 = mass of water = 254 g

\Delta T = change in temperature = T_2-T_1=(23.73-26.01)=-2.28^oC

Now put all the given values in the above formula, we get:

q=[(783J/^oC\times -2.28^oC)+(254g\times 4.184J/g^oC\times -2.28^oC)]

q=-4208.28J=-4.81kJ

Therefore, the amount of heat evolved by a reaction is, 4.81 kJ

a solution with a transmittance of 0.44 is analyzed in a spectrophotometer with 6% stray light. calculate the absorbance reporte
IgorLugansk [536]

The absorbance reported by the defective instrument was 0.3933.

Absorbance A = - log₁₀ T

Tm = transmittance measured by spectrophotometer

Tm = 0.44

Absorbance reported in this equipment = -log₁₀ (0.44) = 0.35654

True absorbance can be calculated by true transmittance, Tm = T+S(α-T)

S = fraction of stray light = 6%= 6/100 = 0.06

α= 1, ideal case

T = true transmittance of the sample

Tm = T+S(α-T)

now, T= Tm-S/ 1-S = 0.44-0.06/ 1-0.06 = 0.404233

therefore, actual reading measured is A = -log₁₀ T = -log₁₀ (0.404233)

i.e; 0.3933
