Answer:

C. Weathering, erosion, and uplift occur at the same rates now as they did in the past.

Explanation:

Hello,

In this case, one remembers the concept of uniformitarianism as everything that has been happening at the same rate through the whole geological time scale until the nowadays. In such a way, one concludes everything changes at the same rate all of the time.

In such manner, based on the uniformitarianism, the processes of weathering, erosion, and uplift occur in the present at the same rate as they have been occurring during the earlier years (past), nonetheless, this concept has not been widely adopted, as there are a lot of proofs unvalidating it.

Best regards.

Name of the unit and type of measurement indicated for 4.8 m

s2008m [1.1K]

<u>Answer:</u> The given quantity is a type of length and is measured i the units of meters.

<u>Explanation:</u>

For the given quantity which is 4.8 meters, the unit is meters ans it the unit used to measure the length of an object.

For example: The height of the building is 150 meters. This statement means that the length of the building from the ground is 150 and it is measured in the units of meters.

Hence, the given quantity is a type of length and is measured i the units of meters.

(A tablet containing calcium carbonate and fillers with a mass of 1.631 g was dissolved in HCl. After the fillers were filtered

FrozenT [24]

Answer:

1) 0.825 grams is the mass of pure calcium carbonate product collected at the end of the experiment.

2) The mass % calcium carbonate in the tablet is 50.58%.

3) The mass % of calcium in calcium carbonate is 40.00 %.

4) Mass of calcium in a tablet is 0.33 g.

Explanation:

Mass of tablet = 1.631 g

Mass of the watch glass = 46.719 g

Mass of the watch glass + mass of calcium carbonate = 47.544 g.

Mass of calcium carbonate = 47.544 g - 46.719 g = 0.825 g

0.825 grams is the mass of pure calcium carbonate product collected at the end of the experiment.

Mass of calcium carbonate = 0.825 g

Percentage of calcium in tablet:

$\%=\frac{\text{Mass of calcium carbonate }}{\text{Mass of tablet}}\times 100$

$\%=\frac{0.825 g}{1.631 g}\times 100=50.58\%$

The mass % calcium carbonate in the tablet is 50.58%.

Percentage of calcium in calcium carbonate :

Molar mass of calcium carbonate = 100 g/mol

Atomic mass of calcium = 40 g/mol

Percentage of calcium in calcium carbonate :

$\%=\frac{\text{atomic mass of calcium}}{\text{Molar mass of}CaCO_3}\times 100$

$\%=\frac{40 g/mol}{100 g/mol}\times 100=40.00\%$

The mass % of calcium in calcium carbonate is 40.00 %.

Mass of calcium carbonate = 0.825 g

The mass % of calcium in calcium carbonate is 40.00 %.

Mass of calcium in a tablet : x

$40.00\%=\frac{\text{Mass of calcium in a tablet}}{0.825 g}\times 100$

$x=40.00\times \frac{0.825 g}{100}=0.33 g$

Mass of calcium in a tablet is 0.33 g.
