A sample of a pure substance with a density of 3 g/mL is separated into two pieces. One piece has a mass of 50 g and the other piece has a mass of 25 g.
What is the density of the larger piece?
Answer: The two pieces have the same density of 3g/mL.
Explanation: the density won't change based on the size or amount of the substance. the density is pre-set (for every X there is y weight, this is always constant).
9. If you have a sample of an element with a density of 8 g/mL and a volume of 10 mL and you cut it in half.
What is the density of each half?
What is the volume of each half?
A sample of a pure substance with a density of 3 g/mL is separated into two pieces. One piece has a mass of 50 g and the other piece has a mass of 25 g.
What is the volume of the smaller one?
Answer:
8.3ml
Explanation:
to get volume u have to divide 25g over the density, i rounded to the nearest tenth, if you don't want to then write out the full number with all the decimals

Identify which of the following best explains the transformation process in photosynthesis.
In photosynthesis, the transformation process is in which the light energy is converted into chemical energy. Therefore, option (D) is correct.
What is Photosynthesis?Photosynthesis can be defined as a process by which phototrophs transform sunlight into chemical energy. This chemical energy can be stored in the form of sugars such as glucose, which are formed from water and CO₂ gas.
In the Photosynthesis process, the components are carbon dioxide and water which yield products oxygen gas, and glucose. Therefore, the photosynthesis reaction is generally said to be an endothermic reaction because the energy is provided in the form of sunlight.
[tex]6CO_2 +6H_2O\longrightarrow C_6H_{12}O_6 +6O_2[/tex]
Each chloroplast in green plants contains a green-colored pigment called chlorophyll which is mandatory for this process to occur. Sunlight is absorbed by the chlorophyll of the plants whereas carbon dioxide gas and oxygen gas enter via the tiny pores of the stomata of leaves.

Two environmental issues of restaurants are the following:
A. Crowding and air quality
B. Crowding and food quality
C. Energy consumption and refrigerants
Answer:
Answer down below
Explanation:
if it has to be 2 of these I think it would be A and B but if it is only one Answer it would be B
Crowding and food quality are two environmental issues of restaurants.
What is the meaning of environmental issues?Environmental issues are defined as harmful effects to Earth and its natural systems due to the actions of humans.
The food supply chain and restaurant customer experience generate a lot of waste – from food waste to plastic waste, and more. Unfortunately, one-third of the world's food gets wasted. This waste alone amounts to 8% of the world's greenhouse gas emissions.
Hence, option B is correct.

fill in the blanks: label the different parts of the rock cycle where igneous, sedimentary, and metamorphic rock are formed.
Answer:
☞rock cycle
=> The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions.
=> There are three main kinds of rocks: igneous rock, metamorphic rock, and sedimentary rock. ... It can erode into sediment or melt into magma. It is formed under extreme pressure and temperature deep inside mountain chains.
Explanation:
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?

D = m/V
0.5g/[tex]cm^3[/tex] = m/(2*3*4)
[tex]\frac{0.5g}{cm^3} = \frac{m}{24cm^3}[/tex]

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.

You will observe the orbits and you have to determine how many planets are in the habitable zone and how many are orbiting successfully. Based on the mass of the star and the placements of the planets, planets may swerve into the star and vanish, collide with each other and vanish, float out of orbit, or all orbit successfully. You will record this information and each planet's orbit in your data table for each trial. If the mass of the sun is 1x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.
If the mass of the sun is 2x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.
If the mass of the sun is 3x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.
