2 years ago a 4.00 l flexible container holds a sample of hydrogen gas at 153 kpa. if the pressure increases to 203 kpa and the
garri49 [273]

To solve this we assume that the gas is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant temperature and number of moles of the gas the product of PV is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

 

P1V1 =P2V2

 V2 = P1 x V1 / P2

 <span>V2 = 153 x 4 / 203</span>

 V2 = 3 L

What is Acid ?<br>please don't report , don't give link and give the correct answer .​
VladimirAG [237]

Answer:

Below in Bold

✧ \underline{ \underline{ \red{ \large{ \tt{E \: X \: P \: L \: A \: N \: A \: T \: I \: O \: N}}}} }:

♨ The word ' acid ' is derived from the Latin word ' acidus ' which means sour. An acid is defined as the substance which gives hydrogen ions or protons ( H+ ) when dissolved in water. For example :

  • Hydrochloric acid
  • Sulphuric acid
  • Nitric acid
  • Carbonic acid
  • Acetic acid

✎ \underline{ \underline{ \purple{ \large{ \tt{Extra \: Info}}}}} :

☃ Physical properties :

  • Acids have a sour taste. But some acids like steric acid, boric acid , salisylic acid do not have a sour taste. Laboratory acids are more corrosive , so they are dangerous to taste.
  • Acid turn blue colour of litmus paper into red and light yellow methyl orange into red. They make phenolphthalein colourless.

☂ Chemical properties :

  • Acids have a high dissolving power and dissolve many substances. Some metals like zinc and magnesium react with acids like dilute sulphuric acid and dilute hydrochloric acid to produce salt and hydrogen gas.
  • Acid react with base to give salt and water.
  • Acid gives H+ ions when dissolved in water.
  • Acid react with metallic carbonates to produce carbon dioxide.

Have a wonderful day / night ! ツ

In a chemical formula such as C6H12O6 and H2O, what do you call the little numbers below the normal line of text.
Morgarella [4.7K]

These are called subscript number.

That is the number below the normal line of test are called subscript number.

This number indicate the indicate the number of atoms of the element present in the chemical formula.

In both of these C₆H₁₂O₆ and H₂O, the number written below the line of the text are called subscript numbers.
