Answer:
The relevant equation is:
CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂
Explanation:
1 mol of calcium carbonate can react to 2 moles of Hydrochloric acid to produce 1 mol of water, 1 mol of calcium chloride and 1 mol of carbon dioxide.
The formed CO₂ is the reason why you noticed bubbles as the reaction took place
The length, width and height of the wall of room is 12.0 ft, 15.0 ft and 9 ft respectively. To calculate the gallons of paint to paint the room with two coats, first calculate the surface area of room that needs to be coated.
The total surface are of room without ceiling will be:
Here, l is length, h is height and w is width of the room.
Putting the values,
Since, 1 gallon of paint is used for area , for of area, volume of paint used will be 0.00267 gallon.
Thus, volume of paint used for area will be:
The above volume is for 1 coat of paint, for 2 coats volume will be:
Therefore, paint required to paint room with two coats is 2.6 gallon.
Answer: Through extensive bonding
Explanation:
Oxidation of two cysteine gives disulphide bonds. They are covalent in nature. Given as;
R-CH2-SH + R'-CH2 +02 = R-CH2-S-S-CH2-R' + H202
They are the stabilizing force behind protein folding the endoplasmic reticulum. Proteins being the backbone of our genetic constitution require disulphide bonding to stabilize the peptide molecules and the extent and number of this bonding determines the Resistance of the protein molecule to extreme conditions e.g extreme heat which denatures proteins and elasticity as well.
The answer would be 84.007 g/mol
The question says that when the ball is placed at the top of the hill it has a lot of potential energy. So I think the higher a ball is placed the more potential energy it will have
