The medium ground finch lives on the Galapagos Islands. Birds with beaks of all sizes were originally part of this population. T
emmainna [20.7K]

Answer:

Finches after drought had stronger and larger beaks to demolish the harder and larger seeds that the drought brought, a difference from those that lived in wet times that had smaller, pointy beaks to eat smaller seeds.

Explanation:

This is called the theory of animal evolution, where animals adapt according to the environment, this theory was just analyzed by this species of animals and many more on the island of Galapagos by Darwin.

What I also approve of as that animal that survives a certain environment is the one that is considered most suitable to live in that place.

What coefficients must be added to balance the following equation?_____NaOH + _____H2 SO4 _____ Na2SO4 + _____ H2O 2, 1, 1, 13,
alexgriva [62]

_____NaOH + _____H2 SO4 _____ Na2SO4 + _____ H2O ,

To balance this equation,

Step 1:

Balance the number of sodium on both side:

by multiplying the NaOH by 2 that is:

2NaOH+H2SO4-------->Na2SO4+H2O

Step2:

As NOW the number of oxygen atom and hydrogen atom are not equal on both sides. So we multiply this H2O by 2 that is:

2NaOH+H2SO4-------->Na2SO4+2H2O

Now the no of all atoms on product side is equal to no of all atoms in the reactant side.

so the coefficient is 2 NaOH+1 H2SO4-------->1 Na2SO4+2 H2O.

Answer:

1. Granite

2. 535.5J

Explanation:

1. The lower the specific heat capacity of a substance, which is the amount of heat needed to raise the temperature of a particular mass of substance by 1 °C or K, the slower the rate at which the temperature is raised.

In this question 1, the substance with the lowest specific heat capacity in J/gK is GRANITE, hence, it will raise temperature the slowest.

2. Using the formula as follows:

Q = m × c × ∆T

Where;

c = specific heat capacity

Q = amount of heat (J)

m = mass of substance

∆T = change in temperature (°C)

m = 35g, c = 0.45 J/g°C, ∆T = 54°C - 20°C = 34°C

Q = 35 × 0.45 × 34

Q = 535.5J
