C₁=4.00 mol/L
c₂=0.50 mol/L
v₂=12.0 mL=0.012 L
n(H₂SO₄)=c₁v₁=c₂v₂
v₁=c₂v₂/c₁
v₁=0.50*0.012/4.00=0.0015 L = 1.5 mL
Answer:
Explanation:
How many moles?
moles=Mass/Molar Mass
Here we have the mass and we can get the molar mass from the periodic table (Na=23, C=12, O=16) So
Molar mass= 23+12+(16x3)=83
Then Moles=0.025/83=<u>1/3320</u>

Answer:
oxygen-carbon dioxide cycle
Animals and plants are connected to each other by the oxygen-carbon dioxide cycle. Plants need the carbon dioxide from animals to live and animals must have the oxygen from plants to survive.

Prochirality is an important concept in biological chemistry because enzymes can distinguish between the two ‘identical’ groups bound to a prochiral carbon center due to the fact that they occupy different regions in three-dimensional space.
The burning of fossil fuels like coal, natural gas etc... leads to the emmission of carbondioxide which is a green house gas and leads to the increase of heat in the atmosphere. This results in greenhouse effect.
