If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature.
If both the normal melting point and the normal boiling point are above room temperature, the substance is a solid.

molecules of 02?
Answers
Answer:
The answer is 1.186 × 10¹² molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 7.14 × 10^35 molecules of O2
We have
[tex]n = \frac{7.14 \times {10}^{35} }{6.02 \times {10}^{23} } \\ [/tex]
We have the final answer as
1.186 × 10¹² molesHope this helps you
Which is the best way to determine if an object is made of pure silver?
O Determine the solubility of the object.
O Test to see if the object is chemically reactive.
Determine the density of the object and compare the known density of pure silver.
O Compare the mass of the silver object to the mass of a piece of pure silver.
Answers
Answer:
The correct option is;
Determine the density of the object and compare the known density of pure Silver
Explanation:
The density of the object is found by finding the weight of the object, and then finding the volume (of water) the object displaces when it is immersed (in water)
The density is then fond by dividing the weighed mass by the volume the object displaces when immersed
Compare the result of the measured density with that of pure silver. If the two have density, as well as other similar physical characteristics, then the object is likely to be pure silver.
Jakasia needed to find the volume of a plastic container in L to see if the 170 L of
solution that she had would fit inside. She knew that one side was 2.5 ft, the
height of the box was 60 cm, and width of the box was 0.8 m. Use dimensional
analysis to determine if Jakasia's solution will fit in the container.
Answers
Answer:
The solution will fit into the container.
Explanation:
The following data were obtained from the question'
Volume of solution = 170 L
Length of container (L) = 2.5 ft
Height of container (H) = 60 cm
Width of container (W) = 0.8 m
Volume of container (V) =?
Next, we shall express the length, height and breadth I the same unit of measurement. In this case, we shall all in centimetres (cm).
For the length:
1 ft = 30.48 cm
Therefore,
2.5 ft = 2.5 ft × 30.48 cm / 1 ft
2.5 ft = 76.2 cm
Thus the length is 76.2 cm
For the width:
1 m = 100 cm
Therefore,
0.8 m = 0.8 m × 100 cm / 1 m
0.8 m = 80 cm
Thus, the width of the container is 80 cm.
Next, we shall determine the volume of the container as follow:
ength of container (L) = 76. 2 cm
Height of container (H) = 60 cm
Width of container (W) = 80 cm
Volume of container (V) =?
Volume = length × width × height
Volume = 76.2 × 80 × 60
Volume = 365760 cm³
Finally, we shall convert 365760 cm³ to litre (L). This can be obtained as follow:
1000 cm³ = 1 L
Therefore,
365760 cm³ = 365760 cm³ × 1 L/ 1000 cm³
365760 cm³ = 365.76 L
Therefore, the volume of the container is 365.76 L
Since the volume of the container (i.e 365.76 L) is bigger than the volume of the solution (i.e 170 L), therefore, the solution will fit into the container.
Does changing the number of neutrons affect the atomic number?

kilometers per hour. During that time, the yacht traveled 50 kilometers. What was the yacht's
speed?
Write your answer as a whole number.
kilometers per hour
Submit
Answers
The speed of the yacht : 100 km/h
Further explanationLinear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration
At constant velocity motion:the speed of vo = v = constant
acceleration = a = 0
Δx = vt or x = xo + vt
An equation of constant velocity motion
[tex]\large {\boxed {\bold {x = v \times \: t}}}[/tex]
x = distance = m
v = speed = m / s
t = time = seconds
A yacht sailed at a steady speed for 0.5 hours, and traveled 50 kilometers
so the velocity/speed:
[tex]\tt v=\dfrac{x}{t}\\\\v=\dfrac{50~km}{0.5~h}=\boxed{\bold{100~km/h}}[/tex]

A trucker is driving from New Jersey to California to make a delivery of couches. He forgets to adjust the pressure of his tires before his trip and end up blowing out two of his tires while driving through Arizona. Whose law does this example depict? What does this law state? Use the law to explain what happened to the tires.
Answers
Answer:
Gay-Lussac's law.
Explanation:
According to Gay-Lussac's pressure law, it states that the pressure of a given mass of gas is directly proportional to the absolute temperature of the gas, the assumption that the volume is kept constant.
Hence, the trucker's tires were blown up because they were under high pressure as he drove from New Jersey to California, as a result of this intense pressure the temperature of the air in the tires began to rise and it directly affected the pressure of the gas in the tires' tubes which also increased to a point that they ended up blowing out, obeying Gay-Lussac's law.

Which statement best describes insoluble substances? Insoluble substances remain the same when in water. Insoluble substances become part of the liquid substance. Water does not remain when an insoluble substance is added. Insoluble substances change from solid to liquid states.
Answers
Answer:
Insoluble substances remain the same when in water.
Explanation:
When a substance is regarded as insoluble, it means that the substance remains the same in water.
Soluble substances usually form one continuous phase with water when they are added to water (eg when salt is added to water).
However, when camphor is added to water, it does not form a single phase with water. It remains the same in the water and maintains a separate phase from the water. Hence camphor is an insoluble substance.

Answers
Answer:
A description of the experiment the chemicals were used for.
Explanation:
A chemical waste label is required to provide information about any hazardous waste present in the container. Some details are mandatory to mention of the chemical waste label to prevent any accident while doing the experiment, that includes:
Chemical compound's name present in the container.Composition and physical state of the waste.Hazardous properties of the waste.The date of manufacturing.Amount of chemical compounds filled in the container.A chemical waste label does not mention or describe the experiment for which the chemicals were used for, scientists, teacher or students should have knowledge of the chemical composition by reading their names and evaluate themselves on which chemical should be used for which experiment.
Hence, the correct answer is "A description of the experiment the chemicals were used for."
The correct answer is A description of the experiment the chemicals were used for.
A chemical waste label must contain all the information about any hazardous waste present in the container. It should clearly indicate the composition of the waste, the date of manufacturing and the amount of chemical compounds filled in the container. A chemical waste label does not need to mention the experiment for which the chemicals were used.
