You have a substance with a length of 2 cm, width of 3 cm, and a height of 4 cm. Its density is known to be .5 g/cm3. What is the mass of the sample you have?
Answer:
12 grams
Explanation:
D = m/V
0.5g/[tex]cm^3[/tex] = m/(2*3*4)
[tex]\frac{0.5g}{cm^3} = \frac{m}{24cm^3}[/tex]
m = 12g

Write an equation for the reaction that takes place in a luminous flame assuming the laboratory gas is Butane
Answer:
Fire's basic combustion equation is: fuel + oxygen —> carbon dioxide + water, a line many of us had drummed into us by school teachers. However, combustion reactions do not proceed directly from oxygen to carbon dioxide.
Explanation:
Fire's basic combustion equation is: fuel + oxygen —> carbon dioxide + water, a line many of us had drummed into us by school teachers. However, combustion reactions do not proceed directly from oxygen to carbon dioxide.
The equation for luminous flame assuming the laboratory gas is butane is fuel + oxygen → [tex]CO_{2} + H_{2}O[/tex].
What is butane?Natural gas, the source of butane, would be a colorless, odorless, but also shapeless gas by nature. This kind of gas is extremely prevalent throughout the world and seems to be comparatively cheap to mine as well as produce.
What is a luminous flame?A burning flame that is clearly seen would be called a luminous flame.
When fuel is reacted with oxygen gas then it will form carbon dioxide and water. It can be written as:
fuel + oxygen → [tex]CO_{2} + H_{2}O[/tex].

Calculate the average distances the car and the washer traveled from the top of the track. Record the averages and your qualitative observation in table B of your student guide. Record what happened to the washer after the car hit the textbook. Explain whether the washer did the same thing every time.
What is the average distance the car traveled _____cm
What is the average distance the washer traveled ______cm
The average distance the car traveled is 75 cm. The average distance the washer traveled is 200 cm.
What is distance?Distance is a measurement of how far away two things or locations are, either numerically or occasionally qualitatively. Distance can be a measurement of length in physics or to an estimate based on other factors in common use.
The phrase is widely used figuratively to refer to a measurement of the distance between two comparable things or a level of separation because spatial cognition is indeed a rich source of implicatures in human understanding. The average distance the car traveled is 75 cm. The average distance the washer traveled is 200 cm.
Therefore, the average distance the car traveled is 75 cm. The average distance the washer traveled is 200 cm.

What is the chemical test for water
Copper(II) sulfate in its purest form is white. Because it is devoid of water, it is also known as anhydrous copper(II) sulfate. A sample of copper(II) sulfate becomes blue when water is present.
• Temperature measurements
Temperature testing aids in determining the pace of biochemical reactions in an aquatic environment, as well as whether they can occur at all. If the water temperature is too high, the water's ability to contain oxygen is reduced, and organisms' ability to withstand certain contaminants is reduced.
• Checking the pH level
This instrument determines the acidity of water. The majority of aquatic species can only thrive in a pH range of 6 to 8.
• Test for chloride
Chloride may be found in both fresh and salt water. Mineral dissolution and industrial pollutants, on the other hand, can worsen its levels.
• Testing for salinity
The total amount of non-carbonate salts dissolved in water is calculated. The salinity of your groundwater can tell you how salty your topsoil will become as the water table rises.
• Oxygen Dissolved Test
The amount of oxygen dissolved in water is measured with this device. Aquatic life can't conduct cellular respiration without it, hence it's an important indication of water quality.
• Test for turbidity
Measures the quantity of suspended particle matter in the water, or, to put it another way, how clear the water is. When there is a lot of turbidity in the water, photosynthesis suffers because light can't get through, which raises the water temperature.
