Gregor Mendel finished his pea plant experiments in 1863 and published his results in 1866. However, few scientists saw Mendel’s

paper for three decades. Even after all that time, Mendel’s discoveries revolutionized the field of genetics. What did Mendel discover about the principles of heredity? Choose the two statements that apply. *

Mendel discovered three laws through his experiments.

Law of dominance; “when a cross is made between a pair of pure contrasting characters, only one of them is able to express itself phenotypically while the other remains hidden in F1 generation.”


Law of segregation; “the two members of a pair of factors separate during the formation of gametes. They do not blend with each other but segregate out into different gametes. Thus any gamete is not impure.”

The density of gold is 19.3 g /cm cubed The density of iron pyrite is 5.0 g /cm cubed. Is a nugget of iron pyrite and a nugget o
telo118 [61]
If you clear volume in the density equation:

\rho = \frac{m}{V}\ \to\ V = \frac{m}{\rho}

The greater the density the lower the volume. This means, the volume of gold nugget will be smaller than the volume of iron pyrite nugget.

V_{gold} = \frac{m}{\rho} = \frac{50\ g}{19.3\ g/cm^3} = \bf 2.59\ cm^3

V_{iron} = \frac{m}{\rho} = \frac{50\ g}{5.0\ g/cm^3} = \bf 10\ cm^3

How do you find the percent yield of a chemical reaction?
kotegsom [21]
To express the efficiency of a reaction, you can calculate the percent yield using this formula: %yield = (actual yield/theoretical yield) x 100. A percent yield of 90% means the reaction was 90% efficient, and 10% of the materials were wasted (they failed to react, or their products were not

Indicate whether each of the following would increase or decrease the rate of reaction
mote1985 [20]

The rate of a chemical reaction is affected by temperature, Catalysts, Suface area, Concentration.

<h3>Rate of reaction</h3>

The rate of a chemical reaction is the rate at which the concentration of reactant molecules decreases or the concentration of product molecules increases.

<h3>Factors effecting rate of chemical reaction </h3>

The factors that affect the rate of chemical reaction include:

  1. Temperature: increase in temperature increases reaction rate while decrease in temperature decreases reaction rate.
  2. Catalysts: the present of catalysts increase the reaction rate. Some catalysts decreases reaction rate and are known as negative catalysts.
  3. Surface area: increase in surface area of reactants increases reaction rate.
  4. Concentration: Increase in concentration of reactants increases reaction rate while decrease in concentration of reactants decreases reaction rate.

Therefore, the rate of a chemical reaction is affected by temperature, Catalysts, Suface area, Concentration.
