Answer:
d 2,4,3
Explanation:
2 Al2O3 ----> 4 Al + 3 O2
that is false it shows you the atoms but the arrangement would have to be a Lewis dot diagram
Answer:
75 Newton
Explanation:
In order to find the force of the object, you must remember that the equation N = (mass x acceleration). Therefore meaning you would divide 300 kilograms, <em>the mass, </em>by 4 meters per second (squared), <em>the acceleration.</em>
Answer:
water, carbon dioxide reacted in the presence of sun light and chlorophyll and form glucose and oxygen.
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 so, the mass of water will be,
The glucose is converted into pyruvate and prod
Answer:
1.55 mol
Step-by-step explanation:
We can use the <em>Ideal Gas Law</em> to solve this problem.
pV = nRT Divide both sides by RT
n = (pV)/(RT)
Data:
p = 1.40 atm
V = 27.5 L
R = 0.082 06 L·atm·K⁻¹mol⁻¹
T = 302 K
Calculations:
n = (1.40 × 27.5)/(0.082 06 × 302)
= 1.55 mol
