Answer:
Yeasts reproduce asexually by a process called budding (see Figure 8.2. 1 and Figure 8.2. 6). A bud is formed on the outer surface of the parent cell as the nucleus divides.
Explanation:
Answer is: because this compound in water dissociates on cations and anions and ions in solution conduct electricity.
Chemical dissociation of acetic acid in water:
CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
When we put electrodes (cathode and anode) in acetic acid solution, positeve and negative ions migrate to electrodes.
Negative acetate ions go to positive electrode and gives electrons to electrode.
Positive hydrogen ions go to negative electrode and gain electrons.
Answer:
1.10231×10-1 lb
Explanation:
we know that one gram is equal to the 0.00220462 lb or we can say that one pound is equal to the 453.592 g.
we have to convert the 50.0 g into pounds:
m (lb)= m(g)× 0.00220462
m(lb)=50×0.00220462
m(lb)=0.110231
in scientific notation:
1.10231×10-1 lb
<span>A hydrocarbon is a molecule whose structure includes only hydrogen and carbon atoms. Hydrocarbons containing between six and ten carbon molecules are the top components of most fuels. In general, these molecules are burned to produce energy. Examples such include: 1. Methane: A fuel in electrical generation. 2. Propane: Generally used heating and cooking. 3. Butane: Generally used in lighters and aerosol cans. 4.Heptane: The major component of gasoline Hydrocarbons are majorly used as a combustible fuel source and are considered a primary source of energy for contemporary civilizations. Oil is an excellent example of a hydrocarbon fuel currently in use all over the world.</span>
