What mass of hydrochloric acid (in grams) can 2.7 g of sodium bicarbonate neutralize? (Hint: Begin by writing a balanced equatio
Julli [10]

Answer:

1.17 grams of HCl can neutralize 2.7 grams sodium bicarbonate

Explanation:

Step 1: Data given

Mass of sodium bicarbonate = 2.7 grams

Step 2: The balanced equation

HCl + NaHCO3 ⇔  NaCl + H2O + CO2

Step 3: Calculate moles NaHCO3

moles NaHCO3 =2.7 g / 84 g/mol= 0.032 moles

Step 4: Calculate moles HCl

For 1 mol NaHCO3 we need 1 mol HCl

For 0.032 moles NaHCO3 = 0.032 moles HCl

Step 5: Calculate mass HCl

Mass HCl = moles HCl * molar mass HCl

mass HCl = 0.032 * 36.46 g/mol= 1.17 grams

1.17 grams of HCl can neutralize 2.7 grams sodium bicarbonate

What is the expected mass (in kg) of a 10 over 5 B isotope? 1 proton = 1.6726 × 10-27 kg 1 neutron = 1.6749 × 10-27 kg A.1.67 ×
Ira Lisetskai [31]
^{10}_5 B
An atom of this isotope contains 5 protons and 10-5=5 neutrons.

5 \times 1.6726 \times 10^{-27} + 5 \times 1.6749 \times 10^{-27} = \\&#10;8.363 \times 10^{-27} + 8.3745 \times 10^{-27}= \\&#10;16.7375 \times 10^{-27}= \\&#10;1.67375 \times 10^{-26} \approx \\&#10;1.67 \times 10^{-26}

The answer is A. 1.67 × 10⁻²⁶ kg.
