Answer: Option (D)

Explanation: Chemical weathering refers to the breakdown of minerals and forming new minerals due to the presence of chemical elements. For example, hydrolysis.

Due to the chemical weathering, initially, the minerals will get dissolved and are carried to the streams and oceans. After that, due to the saturation by water, the crystals will be precipitated out of that existing solution.

This crystals then sinks down to the bottom, forming sedimentary rocks.

Thus, the correct answer is option (D).

1. The speed limit on most city streets is (25 miles). How many meters per minute

irina1246 [14]

Answer:

$Speed = 670.56 \frac{m}{min}$

Explanation:

Given

$Speed = \frac{25 mi}{hr}$

Required

Convert to meters per minutes

$Speed = \frac{25 mi}{hr}$

Start by converting the speed from miles to meters

$1\ mile = 1609.34\ meters.$

So, we have:

$Speed = \frac{25 * 1609.34\ m}{hr}$

$Speed = \frac{40233.5\ m}{hr}$

Next, we convert time from hours to minutes

$1\ hour = 60\ minutes$

So, we have:

$Speed = \frac{40233.5\ m}{60\ min}$

$Speed = 670.56 \frac{m}{min}$

<em>Hence, the equivalent of 25 miles per hour is 670.56 meters per minutes</em>

At STP, adding salt to a 200 mL sample of water produces a saturated 1.7 M solution. How many grams of salt (NaCl) must be added

Illusion [34]

Answer:

$m_{NaCl}=19.9gNaCl$

Explanation:

Hello!

In this case, since the formula for the calculation of molarity is:

$M=\frac{n}{V}$

Whereas we can compute the moles of the solute as shown below, making sure the volume is in liters:

$n=M*V$

Thus, by plugging in we obtain:

$n=0.200L*1.70mol/L=0.170molNaCl$

Next, since the molar mass of NaCl is 58.44 g/mol, we obtain the following mass:

$m_{NaCl}=0.170molNaCl*\frac{58.44gNaCl}{1molNaCl}\\\\m_{NaCl}=19.9gNaCl$

Best regards!

Identify the family to which the compound (h3c−ch2oh) belongs. identify the family to which the compound (a) belongs. alcohol et

OLga [1]

Each of the organic compounds mentioned has a general formula so that we can identify the classification of a certain substance. The compound CH₃CH₂OH is an alcohol because it follows the general formula R-OH, where R is a hydrocarbon chain. In this case, the hydrocarbon chain is ethane. When a hydroxyl functional group is attached, it becomes an alcohol whose name is ethanol.
