Q1. According to Gay Lussac’s Law of Gaseous Volumes,
" when gases combine or are produced in a chemical reaction they do so in a ______ ratio by volumes provided all gases are at same temperature and pressure."
Answer : Option A
Explaination / Solution:
Gay lussac’s law states that when gases combine or are produced in a chemical reaction they do so in a simple ratio by volume provided all gases are at same temperature and pressure.
Mathematically , the law is expressed as ,
[ V / n ] = k
where V represents volume of the gas , n denotes number of moles of the gas & k is proportionality constant .
Thus, volume ratio must be related to the relative number of molecules.
This relationship was crucial in establishing the formula of simple molecules at a time when a distinction between atoms and molecules was not clearly understood.
Q2. In the following reaction, the compound used in the reaction for synthesizing ethyl fluoride is – +AgF → H3C – F + AgBr
Answer : Option C
Explaination / Solution:
Alkyl fluorides is only formed by Swartz reaction.in swartz reaction alkyl chlorides or bromide reacts with metallic flouride agf hg2f2 to form alkyl flourides.
Q3. On the keyboard of computer each character has an ”ASCII” value which stands for
Answer : Option B
Explaination / Solution:
No Explaination.
Q4. In Analog type signals
Answer : Option B
Explaination / Solution:
A signal in which current or voltage varies with time is called analog signal.A vibrating fork produces such a sound signal of single frequency.Every speech or music is a complex signal formed by the superposition of several sinusoidal signals of different amplitudes and frequencies.
Q5. In diploid organism, gametes are produced by meiosis division but in haploid organism gametes are produced by
Answer : Option B
Explaination / Solution:
During mitosis division two daughter cells are produced having same number of chromosome. In meiosis division four daughter cells having half the number of chromosomes are produced. So, haploid organisms follow mitosis division.
Q6. The investment demand function is
Answer : Option B
Explaination / Solution:
No Explaination.
Q7. TISCO stands for
Answer : Option D
Explaination / Solution:
The Tata Iron and Steel Company (TISCO) was incorporated in 1907.
Q8. Angular acceleration vector is defined as
Answer : Option D
Explaination / Solution:
As per the definition of angular accerlation that " it is the time rate of change of angular velocity" , therefore
Q9. The effect of temperature on reaction rate is given by
Answer : Option C
Explaination / Solution:
k =A exp(-kt)
Q10. A pie diagram is also called:
Answer : Option C
Explaination / Solution:
Pie diagrams can be prepared by converting frequencies into angles in such a way that total of all angles should come equal to 360
