in 1866, Gregor Mendel published his paper that described the research that led to his discovery of the laws of inheritance. Mor

e than 30 years later, his results were finally confirmed by Hugo de Vries and Carl Correns. Neither scientist had heard of Mendel’s work, but each was working independently on his own hypothesis about inheritance. Which statement describes the relationship between multiple approaches and familiarity with similar work? Scientists are more likely to explore an area of interest if they are unaware of previous research studies. Older research is more likely to be forgotten, and so it might be inadvertently repeated over and over. It is necessary for multiple approaches to be used when a researcher’s findings are not immediately accepted. Multiple approaches may occur because scientists develop similar interests independently of one another.

What kind of change took place when the magnesium was heated?
Dmitrij [34]

Answer:

You can see that it is an endothermic reaction or heat is being absorbed for the change from magnesium to magnesium oxide. So it is an endothermic reaction. So these are the four reasons why we can say that burning of magnesium ribbon in the air is considered a chemical change.

How many grams of H2O are there in 6.02 x 1023 molecules of water?
tamaranim1 [39]

Answer:

By definition, there are 6.022×1023 such molecules, or NA such molecules in ONE mole of water. And thus in such a quantity there are NA oxygen atoms, and 2×NA hydrogen atoms...and the mass associated with this numerical quantity of water molecules is approx. 18⋅g ...

A lead–tin alloy of composition 30 wt% Sn–70 wt% Pb is slowly heated from a temperature of 150°C (300°F).(a) At what temperature
Novay_Z [31]

Answer:

a) 231.9 °C

b) 100% Sn

c) 327.5 °C

d) 100% Pb

Explanation:

This is a mixture of two solids with different fusion point:

Tf_{Pb}=327.5 C

Tf_{Sn}=231.9 C

<u>Given that Sn has a lower fusion temperature it will start to melt first at that temperature. </u>

So the first liquid phase forms at 231.9 °C and because Pb starts melting at a higher temperature, that phase's composition will be 100% Sn.

The mixture will be completely melted when you are a the higher melting temperature of all components (in this case Pb), so it will all in liquid phase at 327.5 °C.

At that temperature all Sn was already in liquid state and, therefore, the last solid's composition will be 100% Pb.

An object has a density of 1.75 g/mL. Will it float on water? Why?
Advocard [28]

Answer:

The object will not float in water because the density of the object is greater than that of water.

Explanation:

Density of object = 1.75 g/mL

Density of water = 1 g/mL

The Density of the object is 1.75 g/mL and that of water is 1 g/mL. This implies that the object is denser (i.e heavier) than water. Therefore, the object will not float in water, rather it will sink in water since it's density is greater than that of water.
