Which combination of reactants would result in a neutralization reaction with sodium nitrate,
Debora [2.8K]

Answer:

(B) HNO3 + NaOH

Explanation:

Hello,

In this case, for the production of sodium nitrate a substance having the sodium as a cation should react with another substance having the nitrate anion. Moreover, neutralization reactions are carried out when bases react with acids, such is the case of nitric acid and sodium hydroxide:

NaOH+HNO_3\rightarrow NaNO_3+H_2O

Thus, the answer is (B) HNO3 + NaOH  as the other options involve salts rather than acids or bases as starting reactants.

Regards.

How many moles of gas occupy 56.3 L at 0.899 atm and 20.0°C? ​
zzz [600]

Answer:

n = 2.1 mol

Explanation:

Given data:

Number of moles of gas = ?

Volume of gas = 56.3 L

Pressure of gas = 0.899 atm

Temperature of gas = 20°C (20+273 = 293 k)

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

0.899 atm × 56.3 L  = n × 0.0821 atm.L/ mol.K  × 293 k

50.614 atm.L = n × 24.055 atm.L/ mol

n = 50.614 atm.L / 24.055 atm.L/ mol

n = 2.1 mol
