The decomposition of carbon disulfide to carbon monosulfide and sulfur is first order with k=2.8 ×10^-7 at 1000°C .What is the half-life of this reaction at 1000°C?
Answers
Answer:
2.5×10⁶ s
Explanation:
From the question given above, the following data were obtained:
Rate constant (K) = 2.8×10¯⁷ s¯¹
Half-life (t½) =?
The half-life of a first order reaction is given by:
Half-life (t½) = 0.693 / Rate constant (K)
t½ = 0.693 / K
With the above formula, we can obtain the half-life of the reaction as follow:
Rate constant (K) = 2.8×10¯⁷ s¯¹
Half-life (t½) =?
t½ = 0.693 / K
t½ = 0.693 / 2.8×10¯⁷
t½ = 2.5×10⁶ s
Therefore, the half-life of the reaction is 2.5×10⁶ s

Give reason for the following:
(a) Silver nitrate solution is kept in coloured bottles.
(b) Molybdenum is used in the manufacture of ammonia.
(c) Blue solution of copper sulphate changes to green when a piece of iron is added to this solution.
Answers
Answer:
a) In the presence of light silver nitrate decompose to form silver. hence to prevent the decomposition it is kept in dark coloured bottles.
b) Molybdenum is used in the manufacture of ammonium because molybdenum acts as a promoter which increases the efficiency of the catalyst Iron, resulting in better yield of ammonia.
c) When an iron nail immersed in the solution of copper sulphate than iron displaces copper from the solution of copper sulphate because iron is more reactive than copper. Therefore copper sulphate solution colour changes from blue to pale green.

What is an acid?
Acids are defined as substances which on dissociation yield H+ ions , and these substances are sour in taste. Compounds HCl, H₂SO₄ and HNO₃ are acids as they yield H+ ions on dissociation.
According to the number of H+ ions which are generated on dissociation acids are classified as mono-protic , di-protic ,tri-protic and polyprotic acids depending on the number of protons which are liberated on dissociation.
Acids are widely used in industries for production of fertilizers, detergents batteries and dyes.They are used in chemical industries for production of chemical compounds like salts which are produced by neutralization reactions.

О СН3СН2ОН
O CH3CH2CH3
Answers
Answer: Out of the given options [tex]HOCH_{2}OH[/tex] is expected to have the highest viscosity.
Explanation:
The resistance occurred in the flow of a liquid substance is called viscosity.
More stronger is the intermolecular forces present in a substance more will be its resistance in its flow. Hence, more will be its viscosity.
For example, [tex]HOCH_{2}OH[/tex] has strong intermolecular hydrogen bonding than the one's present in [tex]CH_{3}CH_{2}OH[/tex] and [tex]CH_{3}CH_{2}CH_{3}[/tex]. This is because two-OH groups are present over here.
Thus, we can conclude that out of the given options [tex]HOCH_{2}OH[/tex] is expected to have the highest viscosity.

Answers
Answer:
1. Greenhouse gas.
2. Carbon sequestration.
3. Greenhouse effect.
Explanation:
Greenhouse gases can be defined as gases that trap heat within the Earth's atmosphere. Thus, an increase in global temperature is largely caused due to an increase in the amount of greenhouse gases in Earth's atmosphere.
Some examples of greenhouse gases present in the atmosphere are methane, water vapor, carbon dioxide etc.
Matching the descriptions with their term respectively, we have;
1. Greenhouse gas: carbon dioxide, water vapor, methane, nitrogen oxides, and some CFCs that absorb heat and keep it in the earth's atmosphere
2. Carbon sequestration: it's a technology used to capture the carbon released from smokestacks and store it in some part of the environment to keep it out of the atmosphere. Thus, it's a process that is typically used for capturing and the long-term storage of atmospheric carbon dioxide in soil, ocean, plants and geologic formation, so as to reduce global warming or climate change.
3. Greenhouse effect: it's a term used to describe the negative role that greenhouse gases such as methane, water vapor, carbon dioxide etc., play in keeping the earth warm.

Answers
Answer:
7.68 × 10²⁴
Explanation:
Step 1: Calculate the mass of 1 molecule of the monomer CH₂CHCN
We will get the mass of the monomer by adding the masses of the elements.
mCH₂CHCN = 3 × mC + 3 × mH + 1 × mN
mCH₂CHCN = 3 × 12.01 amu + 3 × 1.01 amu + 1 × 14.01 amu = 53.07 amu
Step 2: Convert the mass of the monomer to grams
We will use the conversion factor 1 amu = 1.66 × 10⁻²⁴ g
53.07 amu × 1.66 × 10⁻²⁴ g/1 amu = 8.81 × 10⁻²³ g
Step 3: Calculate "n"
We will divide the mass of the polymer by the mass of the monomer.
n = 676.8 g / 8.81 × 10⁻²³ g = 7.68 × 10²⁴

Answer:
They tend to be more stable
Explanation:
A heterogeneous catalyst is a type of catalyst that exist in a phase which is different from the phases of the reacting mixture or specie or the products and the reactants are absorbed into sites on the catalyst for binding
The heterogeneous catalyst is used in industry because of its main advantage, which is its ease and simplicity of separation from the mixture of the reaction using a straightforward process such as filtration to recover and reuse a costly (heterogeneous) catalyst
Therefore, industry uses the heterogeneous catalyst because the catalyst tend to be more stable and can be easily recovered and reused in its original form
