Answer:
Explanation:
Volume is defined as the space occupied by an object or substance irrespective of its state of matter.The conversion used from millimeter to liter is:
1 milliiliter = 0.001 L
Therefore, we can convert the volume of sample from 2.5 ml in liters as follows.
2.5 ml in liters = 2.5ml x 0.001 L/1ml
= 0.0025 L
Thus, we can conclude that the volume of given sample in liter is 0.0025 L
Hope this helps! :)
Answer:
1. Greenhouse gas.
2. Carbon sequestration.
3. Greenhouse effect.
Explanation:
Greenhouse gases can be defined as gases that trap heat within the Earth's atmosphere. Thus, an increase in global temperature is largely caused due to an increase in the amount of greenhouse gases in Earth's atmosphere.
Some examples of greenhouse gases present in the atmosphere are methane, water vapor, carbon dioxide etc.
Matching the descriptions with their term respectively, we have;
1. Greenhouse gas: carbon dioxide, water vapor, methane, nitrogen oxides, and some CFCs that absorb heat and keep it in the earth's atmosphere
2. Carbon sequestration: it's a technology used to capture the carbon released from smokestacks and store it in some part of the environment to keep it out of the atmosphere. Thus, it's a process that is typically used for capturing and the long-term storage of atmospheric carbon dioxide in soil, ocean, plants and geologic formation, so as to reduce global warming or climate change.
3. Greenhouse effect: it's a term used to describe the negative role that greenhouse gases such as methane, water vapor, carbon dioxide etc., play in keeping the earth warm.
<u>Answer:</u> The correct option is C) 1.68 mol/L
<u>Explanation:</u>
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
.....(1)
Given values:
Given mass of
= 150 g
Molar mass of
= 180 g/mol
Volume of the solution = 0.50 L
Putting values in equation 1, we get:
![\text{Molarity of solution}=\frac{150}{180\times 0.50}\\\\\text{Molarity of solution}=1.68M](https://tex.z-dn.net/?f=%5Ctext%7BMolarity%20of%20solution%7D%3D%5Cfrac%7B150%7D%7B180%5Ctimes%200.50%7D%5C%5C%5C%5C%5Ctext%7BMolarity%20of%20solution%7D%3D1.68M)
Hence, the correct option is C) 1.68 mol/L
The internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy which is transformed into the mechanical energy that accelerates the vehicle ( increasing its kinetic energy ) by causing the pressure and performing the work on the pistons
