What else can I help you with?
Why is the volume of gas collected twice of the volume of other gas when electric current is passed through water?
When an electric current is passed through water, water is split into it's two component gasses- hydrogen and oxygen. You will get about twice as much hydrogen as oxygen- since water (H2O) has twice the hydrogen as oxygen.
In what volume ratio do hydrogen gas and oxygen gas react to form water?
Approximately twice as much volume of hydrogen as of oxygen: Both gases are diatomic and nearly ideal at normal temperature and pressure, and the atomic ratio of hydrogen to oxygen in water is 2.
A mineral with a specific gravity of 3.5 would be expected to weigh 3.5 times as much as an equal volume of?
water. Since the specific gravity of water is 1, the mineral would weigh 3.5 times as much as an equal volume of water.
Volume of gas are not equal during electrolysis of water?
During electrolysis of water, the volume of gas produced at the anode (oxygen) is twice that of the volume of gas produced at the cathode (hydrogen). This is because water molecules (H2O) split into two hydrogen atoms for every one oxygen atom when an electric current is passed through the water during electrolysis.
If the volume of water produced during the reaction doubled what would happen to the ratio of hydrogen and oxygen?
If the volume of water produced during the reaction doubled, it would indicate that the reaction produced twice as much water as before. Since water (H₂O) is composed of two hydrogen atoms and one oxygen atom, the ratio of hydrogen to oxygen in the water remains constant at 2:1. Therefore, even though the volume of water increases, the ratio of hydrogen to oxygen in the reaction does not change; it remains the same.
Does hydrogen or water has high specific heat capacity?
Water has a higher specific heat capacity compared to hydrogen. This means that it takes more energy to raise the temperature of water than it does for hydrogen. Water's high specific heat capacity is one reason why it is able to absorb and store large amounts of heat, which helps regulate temperature in bodies of water and maintain stable climates in coastal areas.
This is expressed as the weight of a mineral compared with the weight of an equal volume of water?
This is the specific gravity of the mineral. It's a comparison of how much mass a given volume of it has compared to the mass of an equal volume of water.
When hydrogen gas and oxygen gas react as much oxygen gas than hydrogen gas is required?
The reaction between hydrogen gas and oxygen gas forms water, with 2 moles of hydrogen gas reacting with 1 mole of oxygen gas. This means that twice as much hydrogen gas is required compared to oxygen gas for the reaction to occur completely.
How much is in one ounce?
One ounce of what? One ounce of hydrogen has a larger volume than, say, one ounce of seawater. And one ounce of hydrogen at sea level has a smaller volume that one ounce of hydrogen at, say, 30 kilometers above sea level. Please be more specific... ;-)
What is the volume ratio of hydrogen to oxygen produced in the decomposition of water?
The decomposition of water (H₂O) into hydrogen and oxygen gas occurs in a 2:1 volume ratio. This means that for every two volumes of hydrogen gas produced, one volume of oxygen gas is generated. This ratio is consistent with the chemical reaction 2 H₂O → 2 H₂ + O₂. Therefore, in terms of gas volumes, hydrogen is produced twice as much as oxygen.
Why does using sodium bicarbonate as electrolyte when performing electrolysis of water produce less than one half volume oxygen for every one volume of hydrogen produced?
Because the electrolysis of water reaction always produces twice as much hydrogen (by volume or by mole) as they do oxygen. H2O(l) -> H2(g) + 1/2 O2(g)
What would the volume be when the temperature is 0 degrees Celsius?
It depends upon what it is, and how much it is at some other temperature. For water that has frozen and is 0 degrees C, the volume, whatever it is, is 91.7 percent of the volume at 20 degrees C (liquid water). Since ice is only about 92% the density of water, ice floats.
