Answer:

Option b) Carbon dioxide and oxygen

Explanation:

Thinking process:

Sodium hydroxide is an alkaline solid substance. It reacts with acids to form salts and water. In this case, it is known that carbon dioxide, CO₂, is an acidic gas. Therefore, the reaction gives a salt that results in carbon dioxide being absorbed by the sodium hydroxide.

Heated copper is an excellent removal of oxygen. This is because monovalent copper, Cu, has a deep binding affinity for oxygen. Hence the the oxygen trapped by the atom.

Answer:

15.52 kj

Explanation:

H2 O mole wt ~ 18 gm

6.35 gm is 6.35 gm /18 gm/mole = .353 moles of H2O

Show your calculation by uploading a picture. Calculate the molar mass of ammonia, NH3

Cloud [144]

Answer:

17.04 g/mol

Explanation:

Molar Mass of NH₃

we know that

Nitrogen has 14.01 gram/mol

And Hydrogen has 1.01 gram/mol

but we have 3 Hydrogens So we multiply

1.01 by 3 i.e., 3.03

Now, add

14.01

+ 3.03

17.04

So, The molar mass of ammonia, NH₃ is

17.04 g/mol

AysviL [449]

Answer:

sublimation

Explanation:

immediately into a gas when thermal energy is added to it. The process is called sublimation. Sublimation is the change of state from a solid to a gas without going through the liquid state.

An aqueous solution of HNO2 is poured onto a solid pile of SrCO3. Identify the net ionic equation for this reaction.

Eddi Din [679]

Answer:

D) SrCO3(s) + 2 HNO2(aq) → Sr(NO2)2 + H2O + CO2(g)

Explanation:

When an acid react with carbonate, it produces nitrate, carbon-dioxide gas and water molecule. When nitrous acid react with Strontium carbonate, three products are formed i. e. Strontium nitrate, carbon-dioxide gas and water. In the reaction, both nitrous acid and Strontium carbonate exchange their partners with each other and forming a different products.
