10 moles of H2 reacts with 5 moles of O2 creating 10 moles of water.
Water has the molar mass 18 g/mole
10 · 18g = 180 g
180 g of water can be produced from 10 moles of hydrogen gas.
Answer:
B and C
Explanation:
powder dissolve faster than particles
the higher the temperature the faster the dissolving process
Answer:
The perceived mass of CO2 would not be affected in large quantities because the splash constitutes small particles of water with sodium bicarbonate that is still reacting. The final calculated mass of sodium bicarbonate in the tablet would be artificially low.
Explanation:
Effervescence is a chemical process that involves the reaction of an acid with a carbonate or sodium bicarbonate, releasing carbon dioxide through a liquid. An example is seen in carbonated beverages, in these the gas that escapes from the liquid is carbon dioxide. The bubbles that are seen are produced by the effervescence of the dissolved gas, which by itself is not visible in its dissolved form.
Answer:
El enlace iónico se da entre dos átomos diferentes (metálico y no. metálico), mientras que el enlace covalente se produce entre dos átomos iguales (no-metálicos). En el enlace covalente hay un compartimiento de electrones, mientras que en el enlace iónico hay una transferencia de electrones
Explanation:
It is the substance that is totally consumed when the chemical reaction is complete....
