Hello:) is hydrogen chloride and hydrochloride acid the same??

Answers

Answer 1

Answer:

Answer:

No because hydrogen chloride is gas and hydrochloric acid is (as stated in the name) an acid. The formula for hydrogen chloride is HCI(g), the little g states that the compound is a gas and the formula for hydrochloric acid is HCl(aq) and the little aq means aqueous.

Answer 2

Answer:

Answer:

no. they are not the same

Explanation: Although, they both do have the same chemical formula HCL, they differ in their states of matter. Hydrogen chloride is a gas whereas hydrochloric acid is a solution of hydrogen chloride gas and water( creates an aquaeous solution). Hydrochloric acid is highly corrossive.

Calculate the mass of barium sulphate formed when 500 cm3 of 1 mol dm sodium sulphate solution is reacted completely with barium chloride solution.[ Relative atomic mass : O = 16; S = 32; Ba = 1371

Answers

Answer:

116.69 g.

Explanation:

Let's write down the reaction taking place when barium chloride reacts with sodium sulfate. This is a double displacement reaction, meaning the anions will be exchanged to produce barium sulfate and sodium chloride:

$BaCl_2(aq)+Na_2SO_4(aq)\rightarrow BaSO_4(s)+2 NaCl(aq)$

Let's find the moles of sodium sulfate. Given the volume of:

$V_(Na_2SO_4)=500 cm^(3)$

Convert this to milliliters knowing that:

$1 mL = 1 cm^3$

Therefore:

$V_(Na_2SO_4)=500 cm^3\cdot (1 mL)/(1 cm^3) =500 mL\cdot(1 L)/(1000 mL) =0.500 L$

Also, we know that:

$1 dm^3 = 1 L$

Convert the molarity into mol/L:

$1 (mol)/(dm^3)\cdot (1 dm^3)/(1 L)=1 (mol)/(L)$

Multiply molarity by volume to find moles of sodium sulfate reacted:

$n_(Na_2SO_4)=1 (mol)/(L)\cdot0.500 L=0.500 mol$

According to stoichiometry of the equation, 1 mole of sodium sulfate produces 1 mole of sulfate, so 0.500 mol of sodium sulfate produce 0.500 mol of barium sulfate. That said, we have moles of barium sulfate produced. To find mass, let's multiply this amount of moles by the molar mass of barium sulfate:

$m_(BaSO_4)=0.500 mol\cdot233.38 (g)/(mol) =116.69 g$

What energy convertion happens when green plants use energy from the sun to make sugar?

Answers

The energy conversion happening here is known as photosynthesis. Photosynthesis is a process where the leaves of a plant absorb water and carbon dioxide, then, using light energy from the sun, convert that into oxygen and sugar.
