Fossil age can determine organism changes related to the time scale. Please select the best answer from the choices provided T F

Oksi-84 [34.3K]

Answer:

True

Explanation:

Fossil age can determine organism changes related to the time scale. Fossils provide scientists with evidence that allows them to hypothesize how living organisms have evolved over time.

fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved. However, by itself a fossil has little meaning unless it is placed within some context. The age of the fossil must be determined so it can be compared to other fossil species from the same time period. Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms.

The mole fraction of nitrogen in the air is 0.7808. this means that 78.08% of the molecules in the air are nitrogen. when the at

Pachacha [2.7K]

Answer:

$p = \boxed{\text{593 torr}}$

Explanation:

For this question, we must use Dalton's Law of Partial Pressures:

The partial pressure of a gas in a mixture of gases equals its mole fraction times the total pressure:

$p = \chi p_{\text{tot}}$

Data:

χ = 0.7808

$p_{\text{tot}} = \text{ 760 torr}$

Calculation:

$p = 0.7808 \times \text{ 760 torr}\\\\p= \boxed{\textbf{593 torr}}$

At 100.0∘C, the ion product of water is 5.13×10−13. What is the concentration of hydroxide ions at this temperature? Your answer

Trava [24]

Answer: The concentration of hydroxide ions at this temperature is $7.16\times 10^{-7}$

Explanation:

When an expression is formed by taking the product of concentration of ions raised to the power of their stoichiometric coefficients in the solution of a salt is known as ionic product.

The ionic product for water is written as:

$K_w=[H^+][OH^-]$
