Answer:
Explanation:
budding
Figure 13.3 (a) Hydra reproduce asexually through budding: a bud forms on the tubular body of an adult hydra, develops a mouth and tentacles, and then detaches from its parent. The new hydra is fully developed and will find its own location for attachment.
Answer:
Chemical reaction.
Step-by-step explanation:
In the experiment, a catalyst is added to concentrated hydrogen peroxide.
The hydrogen peroxide <em>decomposes</em> rapidly, according to the equation
2H₂O₂(ℓ) ⟶ 2H₂O(ℓ) + O₂(g)
New substances are formed, and old ones disappear, so this is a chemical reaction.
The reaction also releases a <em>large amount of heat</em>.
The rapidly-expanding oxygen gas caries with it droplets of water and hydrogen peroxide (and probably some steam, as well).
The visual effect is like a genie escaping from its bottl<em>e</em>.
2C₃H₇OH + 9O₂ = 6CO₂ + 8H₂O
V(O₂)=12.0 dm³
n(C₃H₇OH)=0.1 mol
n(O₂)=12.0 dm³/22.4 dm³/mol=0.5357 mol
C₃H₇OH : O₂ 2:9 1:4.5
0.1:0.5357
oxygen in excess
V(CO₂)=3Vm*n(C₃H₇OH)
V(CO₂)=3*22.4*0.1=6.72 dm³
Answer:
B
Explanation:
As you move down the periodic table in the carbon family, the atomic radius and ionic radius increase while electronegativity and ionization energy decrease. Atom size increases moving down the group because an additional electron shell is added.
In a redox reaction an electron is lost by the reducing agent
