What will happen if a solution of sodium hydrocarbonate is heated give the equation of the reaction involved.

1 answer:

7 0

If heated, a decomposition reaction takes place. Sodium hydrocarbonate decompose to sodium carbonate, carbon(IV) oxide and water.

Balanced chemical equation of heating sodium bicarbonate:

2NaHCO₃ → Na₂CO₃ + CO₂ + H₂O

NaHCO₃ is sodium hydrocarbonate

Na₂CO₃ is sodium carbonate

CO₂ is carbon(IV) oxide

H₂O is water

This is chemical change (chemical reaction), because new substances are formed (sodium carbonate, carbon(IV) oxide and water), the atoms are rearranged, so there is no sodium bicarbonate (NaHCO₃) in the test tube.

Decomposition is reaction where one substance is broken down into two or more simpler substances.

How many grams of N2 gas are present in 1.13 L of gas at 2.09 atm and 291 K?

solong [7]

Answer:

Mass= 2.77g

Explanation:

Applying

P=2.09atm, V= 1.13L, R= 0.082, T= 291K, Mm of N2= 28

PV=nRT

Moles(n) = m/M

PV=m/M×RT

m= PVM/RT

Substitute and Simplify

m= (2.09×1.13×28)/(0.082×291)

m= 2.77g

One beaker contains 19.93 mL, another contains 14.0 mL and a third contains 10.6 mL. What is the total volume of the three beake

Juli2301 [7.4K]

Answer:

$\large \boxed{\text{44.5 mL}}$

Explanation:

When adding or subtracting values, you must round your answer to the same "place" as the measurement with its last significant figure furthest to the left.

That is, you round off to the same number of decimal places as the measurement with the fewest decimal places.

$\begin{array}{r|r}19.9& \text{3 mL}\\14.0&\text{mL}\\10.6&\text{mL} \\\mathbf{44.5} &\textbf{3 mL}\\\end{array}$

The measurements of 14.0 and 10.6 have one digit after the decimal point, so you round the sum to have only one digit to the right of the decimal.

The number to be dropped (3) is less than 5, so you drop it.

$\text{The total volume of the three beakers is $\large \boxed{\textbf{44.5 mL}}$}$
