Answer:
Filling in the blank, this is an example of <u>chemical weathering</u> which happens <u>to rocks</u> overtime.
Explanation:
Chemical weathering occurs when rocks are disintegrated by chemicals.
Rain water becomes acid rain when it reacts with carbon dioxide in the atmosphere (to form carbonic acid, HCO3).
When acidic rainwater falls and stays on rocks, chemical reactions take place with the minerals present in the rock, causing the rock to weather.
Areas with immense carbon dioxide and sulphur dioxide pollution increases rain water acidity, which in turn causes moisture in the atmosphere to dissolve these gases and produce acid rain.
Answer:
Conversion gives 42,107 km in total
Explanation:
A marathon covers 26 miles and 285 yards.
If 1 kilometer is 0.6214 miles, then how many kilometers are 26 miles, then:
1 km = 0.6214 miles
X = 26 miles
X = 41,841 km
Now if 1 yard is 36 inches, how many inches is 285 yards?
1 yard = 36 inches
285 yards = X
X = 10260 inches
If an inch is equal to 2.54 cm, how many centimeters are 10260 inches?
1 inch = 2.54 cm
10260 cm = X
X = 26060.4 cm
And 26060.4 cm is 0.260604 km
Finally, the sum of the distance would be:
41.841 km + 0.260604 km = 42.107 km
Answer:
They are synthesized from raw materials
Explanation:
All synthesized products goes through lots of processes. This processes involves the conversion of substances known as raw materials into a more useful and modified form.
These synthesized products are usually more useful and made in order to solve a given problem or offer a particular service. Raw materials are cheaper than the synthesized products and are common in all industries and fields.
Answer:
4687.5 mL
Explanation:
Given that the density of the substance = 8.96 g/mL
Mass = 42.0 kg
The conversion of kg into g is shown below as:
1 kg = 1000 g
So, mass = 42.0 × 1000 g = 42000 g
Volume = ?
So, volume:
The volume of the 42.0 kg of the substance = 4687.5 mL
