Which type of bonding is present in NH4Cl?

NH4Cl (Ammonium chloride) exhibits multiple types of bonding: Ionic Bonding: Between NH4+ (ammonium ion) and Cl- (chloride ion). Covalent Bonding: Within the NH4+ ion itself, between nitrogen and hydrogen atoms. Coordinate Covalent Bonding: One of the N-H bonds in NH4+ is formed by nitrogen donating a lone pair to a hydrogen ion (H+).

When CuSO4 is electrolyzed in aqueous solution using copper electrodes, then the substance which deposits at the cathode is:

During the electrolysis of CuSO4 using copper electrodes: At the cathode (negative electrode), copper ions (Cu2+) from the solution are reduced to copper metal (Cu): Cu 2 + + 2 e − → Cu Cu 2+ +2e − →Cu At the anode (positive electrode), copper metal dissolves into the solution as Cu2+ ions: Cu → Cu 2 + + 2 e − Cu→Cu 2+ +2e − Thus, copper metal deposits on the cathode.

Aldehydes can be synthesized by the oxidation of:

Aldehydes are synthesized by the oxidation of primary alcohols. The oxidation process involves removing hydrogen atoms from the primary alcohol, forming an aldehyde. For example, the oxidation of ethanol (a primary alcohol) produces acetaldehyde: CH 3 CH 2 OH → CH 3 CHO + H 2 O CH 3 ​ CH 2 ​ OH→CH 3 ​ CHO+H 2 ​ O

The products of the fermentation of a sugar are ethanol and:

During fermentation, sugars such as glucose are converted by yeast or bacteria into ethanol and carbon dioxide. The general equation for this process is: C 6 H 12 O 6 → 2 C 2 H 5 OH + 2 CO 2 C 6 ​ H 12 ​ O 6 ​ →2C 2 ​ H 5 ​ OH+2CO 2 ​ Thus, the products of sugar fermentation are ethanol (C2H5OH) and carbon dioxide (CO2).

When a helium atom loses an electron, it becomes:

When a helium atom loses an electron, it becomes a positively charged ion (He⁺), also known as a positive helium ion. It is not an alpha particle (which consists of 2 protons and 2 neutrons), nor a proton (which is a hydrogen nucleus), nor a negative ion (which would require gaining an electron).

Beta ray emitted by a radioactive substance is:

Beta particles (β-) are high-energy, high-speed electrons emitted by the nucleus during radioactive decay, specifically from the transformation of a neutron into a proton within the nucleus, releasing an electron (beta particle) and an antineutrino.

If the mass of the bob of a pendulum is doubled its time period is:

The time period of a simple pendulum is given by 𝑇 = 2𝜋 √ 𝐿 / g, where 𝐿 is the length of the pendulum and 𝑔 is the acceleration due to gravity. The mass of the bob does not affect the time period of the pendulum.

Which one is the most stable element on the basis of binding energy?

The most stable element on the basis of binding energy per nucleon is iron (Fe). The binding energy per nucleon reaches a maximum for iron-56, which means it is the most stable nucleus. This concept is crucial in nuclear physics, as it explains why nuclear fusion occurs in stars up to iron and why heavier elements are formed by supernovae explosions.

Resistance in RC circuit of time constant 2 seconds is 1000 Ohms. What is the value of C in the circuit?

The time constant (𝜏) for an RC circuit is given by the product of resistance (R) and capacitance (C): 𝜏 = R⋅C. given 𝜏 = 2 seconds and R = 1000 ohms: C = 𝜏 / R = 2s / 1000 ohms = 0.002 farads = 2000 μfarads however, as 2 μF aligns closely with the other options, we'll check: C = 2s / 1000 ohms = 2 x 10−3 F = 2000 μF

The Lenz’s law refers to induced __________

Lenz's Law states that the direction of the induced electromotive force (emf) will always be such that it opposes the change in magnetic flux that produced it. This is a fundamental principle in electromagnetism and is key to understanding how induction works.

In which of the following, output is similar to NAND gate if input A=0 and input B=1.

For inputs A=0 and B=1: NAND gate outputs 1 (since 0 AND 1 is 0, and NOT 0 is 1). XOR gate outputs 1 (since XOR is true when inputs differ) Hence, the correct option is C) XOR.
