Voltage difference is the push that causes charges to flow from high to low areas.
Answer:
157.79 g
Explanation:
The definition of molality is:
- molality = moles of solute / kilogram of solvent
This means that in a 2.7 molal solution, there are 2.7 moles of NaCl per kilogram of water.
So now w<u>e convert those 2.7 moles of NaCl to grams</u>, using its <em>molar mass</em>:
- 2.7 mol * 58.44 g/mol = 157.79 g
Answer:
Digestion take place in Fats.
Answer:
Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat. As you can see, copper is the preferred metal for electrical wires for several reasons. It has high electrical conductive; it's inexpensive; it's ductile; and it's thermal resistant.
Answer:
New temperature = 546 K
Explanation:
Given that,
Initial volume, V = 200 L
Initial temperature, T = 273 K
We need to find the new temperature if the volume is doubled.
The relation between temperature and volume is direction. If volume is doubled, it means the temperature gets also doubled.
New temperature of the gas = 2(273) = 546 K
