Answer:HBr

Explanation:According to Bronsted Lowry, an acid is a proton donor while a base is a proton acceptor.

HBr donates a proton H+ to H20 thereby resulting in the product H30+ + Br-

Acid indigestion is sometimes neutralized with an antacid such as magnesium hydroxide (Mg(OH)2). What products will be released

Lunna [17]

Answer: d) $MgCl_2$ and $H_2O$ 

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

A neutralization reaction is a double displacement reaction in which an acid reacts with base to produce salt and water. The $H^+$ ions from water reacts with $OH^-$ ions from base to give water.

$2HCl+Mg(OH)_2\rightarrow MgCl_2+2H_2O$

Thus products that will be released when the antacid is mixed with the hydrochloric acid in the stomach are $MgCl_2$ and $H_2O$

Rank the following molecules (1st, 2nd, 3rd, 4th) in the order that they melt.

Daniel [21]

Sodium chloride has the highest melting point while iodine has the least melting point.

The melting points of solid substances depends on the nature of intermolecular forces that exists in the substance. The stronger the magnitude of intermolecular forces in a substance, the higher its melting point.

The order of melting points of the solids shown in question is as follows;

1st - Sodium chloride
2nd - sucrose
3rd - paraffin
4th - Iodine

Sodium chloride has the highest melting points because it is an ionic substance. Among the molecular sucrose and paraffin, sucrose has a higher melting point than sucrose because it has a greater molar mass. Iodine, a molecular substance has the least molar mass and the least melting point in the list.

Hello summer roses~<br>help me with these questions

Olegator [25]

Answer:

The process of "slaking" of lime refers to the use of excess water for hydration. balanced equation: CaO + H₂0 = Ca(OH)₂ + heat released

First lets know which oxide is quick lime - CaO, is basic in nature as a result it combines with acidic oxides using heat. For example we are gonna make it react with silicon dioxide which is a very weak acid: CaO + SiO₂ → CaSiO₃

Hope this helps ~

A piece of high-density Styrofoam measuring 24.0 cm by 36.0 cm by 5.0 cm floats when placed in a tub of water. When a 1.5 kg boo

zheka24 [161]

Explanation:

The given data is as follows.

Width of Styrofoam = 24.0 cm

Length of Styrofoam = 36.0 cm

Height of Styrofoam = 5.0 cm

Therefore, volume of the Styrofoam will be calculated as follows.

Volume = length × width × height
