Answer:
1027.62 g
Explanation:
For :-
Mass of = 296.1 g
Molar mass of = 27.66 g/mol
The formula for the calculation of moles is shown below:
Thus,
From the balanced reaction:-
1 mole of react with 3 moles of oxygen
Thus,
10.705 mole of react with 3*10.705 moles of oxygen
Moles of oxygen = 32.115 moles
Molar mass of oxygen gas = 31.998 g/mol
<u>Mass = Moles * Molar mass = 32.115 * 31.998 g = 1027.62 g</u>
Answer:
319.3g Cu2S
Explanation:
There is 127.1 g Copper in 159.16g (molar mass) of Cu2S. Let x be Cu2S required. Then x * (127.1/159.16) = 255.0g. So x = 319.3g
Anode
A helpful acronym to assist you in answering such questions : An Ox
Red Cat
basically means Anode, Oxidation (An Ox)
Reduction, Cathode (Red Cat)
Cellular respiration is the reverse of photosynthesis because it is glucose + oxygen yield carbon dioxide water and ATP while photosynthesis is carbon + water yields oxygen and glucose. Cellular respiration is the way cells gain energy from the sun. Photosynthesis is the plants way of producing energy and these processes are basically the reverse of the other .
Explanation:
Boiling point is defined as the temperature at which vapor pressure of liquid becomes equal to the atmospheric pressure.
When high temperature is provided to a liquid then forces of attraction between the molecules decreases and kinetic energy of its molecules increases. As a result, collision between the particles increases.
Also, it is known that kinetic energy is directly proportional to temperature. Therefore, when temperature increase kinetic energy also increases.
Hence, we can conclude that statements correctly describing water boiling in a pot are as follows.
- The water’s internal kinetic energy is increasing.
- The water’s temperature is increasing.
- Individual water molecules are escaping.
