Answer: gradual increase in temperature of ice from −15°C to 0°C, holding at 0°C as ice melts to water
Explanation: The heat used to convert solid to liquid is gained by molecules to gain kinetic energy and thus the molecules start moving faster and the temperature increases.
But as the melting point is approached i.e. , the temperature remains constant as now the heat given is used to break the inter molecular forces and thus is not reflected in terms of temperature increase. This hidden heat is called as latent heat.
The temperature remains constant till the phase change is complete.
The product formed when Ag2O decompose is O2 ( answer c)
explanation
Decomposition involve separation of a single chemical compound into two ore more elemental parts Ag2O decomposes to yield Ag and O2
that is 2Ag2O→ 4Ag + O2
2 moles of Ag2O decomposes to yield 4 moles of Ag and 1 mole of O2
Answer:
$438,000.00
Explanation: There are 365 days in one year. You multiply this by 6, and get 2,190 days. You multiply $200 and 2,190, get 438,000.00
Answer:
Yes. Diesel works the best.
Explanation:
Homemade Napalm can be made using the following procedures; Using an enormous container, fill it about halfway with gasoline. Which means Diesel works the best. Break the special soap, Styrofoam(polystyrene), plate into small pieces.
Answer:
218.98 grams
Explanation:
Given that,
No. of moles, n = 2.3
The molar mass of magnesium chloride is 95.211 g/mol.
We need to find the mass of 2.3 moles of magnesium chloride.
We know that,
No. of moles = given mass/molar mass
Let m be the given mass. So,
So, the required mass is equal to 218.98 grams.
