Answer:
24 molecules of H20
Explanation:
Photosynthesis:
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
Carbon dioxide + water + energy → glucose + oxygen
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Chemical equation:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen.
consider 1 mole contain 1 molecule.
So in order to produced 4 molecules of sugar number of molecules of water carbon dioxide needed are,
6 × 4 = 24 molecules
24 molecules of water and 24 molecules of carbon dioxide needed.
Answer:
Sample C has the highest density
Explanation:
Step 1: data given
Sample A has a mass of 224.96 grams
Sample B has a mass of 0.55632 lbs = 252.3425 grams
Sample C has a mass of 0.30648 kg = 306.48 grams
The volume is for all the sample equal
Step 2: Calculate density
We suppose the volume is 1000 mL
Density = mass / volume
Density sample A = 224.96 grams / 1000 mL = 0.22496 g/mL
Density sample B = 252.3425 grams / 1000 mL = 0.2523425 g/mL
Density sample C = 306.48 grams / 1000 mL = 0.30648 g/mL
Sample C has the highest density
Answer:
d≈ 1.15 g/cm^3
Explanation:
The density of an object can be found by dividing the mass over the volume.
d= m/v
The mass of the object is 54.3 grams and the volume is 47.18 cubic centimeters.
m= 54.3 g
v= 47.18 cm^3
Substitute the values into the formula.
d= 54.3 g/ 47.18 cm
Divide.
d= 1.150911403136922 g/cm^3
Let’s round to the nearest hundredth. The 0 in the thousandth place tells us to leave the 5 in the hundredth place.
d ≈ 1.15 g/cm^3
The density is about 1.15 grams per cubic centimeter.
<u>Answer:</u> The equilibrium constant for the overall reaction is
<u>Explanation:</u>
The given chemical equations follows:
<u>Equation 1:</u>
<u>Equation 2:</u> ( × 2)
The net equation follows:
The equilibrium constant for the net reaction will be the multiplication of two above equations.
If the equation is multiplied by a factor of '2', the equilibrium constant of the net reaction will be the square of the equilibrium constant of respective reaction.
The value of equilibrium constant for net reaction is:
Hence, the equilibrium constant for the overall reaction is
I believe it would be milk souring.
