Answer:

2.4 dm-3

Explanation:

Equation of the reaction;

2HCl(aq) + Ba(OH)2(aq) -------> BaCl2(aq) + 2 H2O(l)

Volume of acid VA = ??

Concentration of acid CA = 0.25 moldm-3

Volume of base VB = 2.0 dm^3

Concentration of base CB = 0.15 moldm-3

Number of moles of acid NA = 2

Number of moles of base NB = 1

CAVA/CBVB = NA/NB

CAVANB = CBVBNA

VA = CBVBNA/CANB

VA = 0.15 * 2 * 2/0.25 *1

VA = 2.4 dm-3

seropon [69]

Answer:

B. an air-conditioning system.

Explanation:

Refrigeration is defined as a process of cooling a system to lower temperature below the surrounding temperature while the removed heat is rejected at higher temperatures.

Heat pumps use the heat output of the refrigeration process, which may also be designed to be reversible, but are otherwise similar to air conditioning units.

How many grams of NO can be produced from the following reaction if 68.2 grams of NO2 is consumed?
Semenov [28]

Answer:

Option 4. 14.8 g

Explanation:

3NO2 + H2O → 2HNO3 + NO

First let us calculate the molar mass of NO2 and NO. This is illustrated below;

Molar Mass of NO2 = 14 + (2x16) = 14 + 32 = 46g/mol

Mass of NO2 from the question = 3 x 46 = 138g.

Molar Mass of NO = 14 +16 = 30g/mol

From the equation,

138g of NO2 reacted to produce 30g of NO

Therefore, 68.2g of NO2 will react to produce = (68.2 x 30)/138 = 14.8g of NO.
