Answer:
Molar mass of NaHCO3 = 84.00661 g/mo
Explanation:
This compound is also known as Baking Soda or Sodium Bicarbonate.
Convert grams NaHCO3 to moles or moles NaHCO3 to grams
Molecular weight calculation:
22.98977 + 1.00794 + 12.0107 + 15.9994*3
Answer:
Equilibrium shifts to the right
Explanation:
An exothermic reaction is one in which temperature is released to the environment. Hence, if the reaction vessel housing an exothermic reaction is touched after reaction completion, we will notice that the reaction vessel e.g beaker is hot.
To consider the equilibrium response to temperature changes, we need to consider if the reaction is exothermic or endothermic. In the case of this particular question, it has been established that the reaction is exothermic.
Heat is released to the surroundings as the reactants are at a higher energy level compared to the products. Hence, increasing the temperature will favor the formation of more reactants and as such, the equilibrium position will shift to the left to pave way for the formation of more reactants. Thus , more acetylene and hydrogen would be yielded
Answer:
The International Bottled Water Association (IBWA), Alexandria, Va., and Beverage Marketing Corporation (BMC), New York, recently released 2015 bottled water statistics showing that Americans' consumption of bottled water increased by 7.9 percent and bottled water sales were up 8.9 percent from the previous year.
Explanation:
Answer: 5.4
Explanation: The Law of Impenetrability says that two objects can't occupy the same space at the same time; therefore, the pennies and the water can't occupy the same space at the same time. Without the pennies the water level read 20.6 mL, dropping in the pennies gives a level of 26.0.
Answer:
The incorrect statement is: SO₂ gains electrons
Explanation:
A chemical reaction that involves the simultaneous transfer of electrons between two chemical species, is known as the redox reaction.
Given chemical reaction: 2SO₂(g) + O₂(g) → 2SO₃(g)
In this redox reaction, S is present in +4 oxidation state in SO₂ and +6 oxidation state SO₃. Whereas, O is present in 0 oxidation state in O₂ and -2 oxidation state in SO₃.
<u>Therefore, SO₂ loses electrons and thus gets oxidized. Whereas, O₂ gains electrons and thus gets reduced. </u>
<u>In this reaction, SO₂ is the reducing agent and O₂ is the oxidizing agent.</u>
