One difference is
humans and animals only carry genes(traits Ex; like blue eyes and red hair phenotype) and plants carry chromosomes(energy from the sun)
Answer:
B. It increases.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
It is clear that, at constant P, the volume of the gas (V) is directly proportional to the temperature of the gas.
<em>V ∝ T.</em>
<em></em>
<em>So, If a balloon is heated, the volume of the air in the balloon if the pressure is constant:</em>
B. It increases.
Answer: 23 g
the mol of Fe is 11,5/56 = 23/112 (mol)
the mol of CO is (mol)
we have:
Fe2O3 + 3CO => 2Fe + 3CO2
23/112 69/112 23/56
=> the mol of Fe is 23/56 mol
=> the mass of Fe is 23/56.56 = 23 (g)
