Answer: 226 Subscript 88 Baseline Upper R a right arrow Superscript 222 Subscript 86 Baseline Upper R n + Superscript 4 Subscript 2 Baseline Upper H e
Explanation:
Alpha decay : When a larger nuclei decays into smaller nuclei by releasing alpha particle. In this process, the mass number and atomic number is reduced by 4 and 2 units respectively.
The general representation of alpha decay reaction is:
Representation of Radium decays to form Radon
Thus 226 Subscript 88 Baseline Upper R a right arrow Superscript 222 Subscript 86 Baseline Upper R n + Superscript 4 Subscript 2 Baseline Upper H e represents alpha decay.

Answer:
The α‑helix is held together by hydrogen bonds between the amide N−H and C=O groups.
Disulfide bonds stabilize secondary structure.
Explanation:
Proteins have primary, secondary, tertiary and quartinary structures.
The secondary structure of a protein is the regular, recurring sequence of amino acid in a polypeptide chain. Secondary structure of proteins give rise to the folding observed in the structure of a protein.
The major secondary structures of a protein are α-helices and β-structures.
Answer: is equal to the gravitational pull on an object
Explanation:
Answer:-
241.66 mL
Explanation:-
Volume of HCl = 145 mL / 1000 = 0.145 L
Strength of HCl = 0.25 M
Number of moles of HCl = Strength x volume
= 0.25 M x 0.145 L
= 0.03625 moles
According to the balanced chemical equation
NaOH(aq) + HCl(aq) → H 2 O(l) + NaCl(aq)
1 mol of HCl reacts with 1 mol of NaOH.
∴0.03625 moles of HCl reacts with 0.03625 moles of NaOH.
Strength of NaOH = 0.15 M
Volume of NaOH = Number of moles / strength
= 0.03625 moles / 0.15 M
= 0.24166 L x 1000
= 241.66 mL
