Imagine that you heat a pot of water to a boil (212°F), then you turn off the stove and let the water sit there. The room is at room temperature (72°F) What temperature do you predict the water cool to after sitting for 8 hours? (
Answers
Answer:
72 °F
Explanation:
Hello,
In this case, since matter tend the be stable at conditions they do not change, if we have water at room temperature (72 °F) and we heat it until boiling but then we turn off the stove, we molecularly see that due to the heat, the molecules start moving faster and crashing to each other; however when that fed energy starts being removed as the stove gets turned off, the molecules lose energy causing them to start moving slower so they lose energy until a point the remain at the initial status, that is 72 °F because thermal equilibrium is reached. Therefore it is likely for the water to be at 72 °F as well once 8 hours have passed, because a thermal equilibrium is reached with the environmetnal temperature.
Best regards.

newly discovered substance on Mars has a mass of 2.3x10-5,g and volume of
200 ml. What is its density in g/mL?
Answers
Answer:
The answer is
[tex] \huge 1.15 \times {10}^{ - 7 } \: \: g/ml \\ [/tex]
Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question we have
[tex]density = \frac{2.3 \times {10}^{ - 5} }{200} \\ [/tex]
We have the final answer as

Tidal ranges - differences between neap tides and spring tides - graph ... The perigee of the moon can occur at any point in the orbit around the earth due ...
The correct option is option C among all the given options. This is because a spring tide occurs when the Moon and the Sun are aligned and pull on Earth.
What is tide?Any periodic deformation of one astronomical entity brought on by the gravitational pull of another is referred to as a tide. The most well-known are the regular fluctuations in Earth's sea level that are caused by shifts in the Sun's and Moon's relative locations. You can think of the tides as driven waves, flowing waves, and standing waves.
A tide with the largest difference between water levels at high and low tides is known as a spring tide. Two spring tides occur in each lunar cycle. This is because a spring tide occurs when the Moon and the Sun are aligned and pull on Earth. The Moon's ability to produce tides results from changes inside its gravitational field across Earth's surface in comparison to its strength at the planet's center.
Therefore, the correct option is option C among all the given options.

When an unknown amount of methane reacts with 40.7 g of chlorine, 40.5 g of methyl chloride and 36.5 g of hydrogen chloride form how much methane was used round to the tenth
Answers
Answer:
36.3 gram
Explanation:
CH₄ + Cl₂ = CH₃Cl + HCl
In any reaction , mass is conserved
mass of product = 40.5 + 36.5 = 77 g
Let methane reacted be x .
mass of reactant = x + 40.7
mass of reactant = mass of product
x + 40.7 = 77
x = 36.3 gram
methane reacted = 36.3 gram.

Answers
Answer:
See explanation
Explanation:
a) number of moles = reacting mass/molar mass
Reacting mass = 10g
Molar mass of CaBr2= 200 g/mol
Number of moles = 10g/200g/mol
b) Avogadro's number = 6.02 × 10^23
c) melting point of the CaBr2
Recall that pure substances have sharp melting points while impure substances melt over a range of temperatures.
d) They are both halide salts of calcium hence they are expected to display similar chemical properties.
