Carbon powder and iron fillings are both black powders. When mixed together they look like one black powder. Which of these would be best to use to seperate the iron fillings from the carbon powder. A. a magnifying glass B. heat C. a magnet D. water
Answer:
C
Explanation:
The iron filings will be attracted to the magnet and will separate from the carbon powder.
The best method to be used to separate the iron fillings from the carbon powder is through the use of water.
The separation of carbon powder and iron fillings in powdered form can be achieved in a blast furnace flue dust. The blast furnace flue dust is usually combined with water to create a slurry that contains (50-70)% solids.
The slurry is fortified with a flotation agent as well as a frothing agent. The content in the slurry is stirred rapidly to cover the carbon particles completely with the flotation agent.
The carbon powdered particles float on top of the slurry, while the iron fillings are collected as a sink product.

Which of the following trends can be observed when moving down a column in the periodic table
Explanation:
A column on the periodic table represents a period.
These are some of the variations observed across a period;
Atomic radii decreases progressively from left to right due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells. Ionization energy increases progressively from left to right due to decreasing atomic radii. Electronegativity increases from left to right. Electropositivity decreases across a period.What is the concept of Absolute Zero
Answer:
Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There's a catch, though: absolute zero is impossible to reach.

How many protons, electrons, and neutrons does an atom with atomic number 50 and mass number 120 contain?
The study of chemicals and bonds is called chemistry.
The correct answer is 50, 50, and 70.
In an element, there are the following things:-
ElectronsProtonsNeutronsIn elements, the number of protons and electrons are the same. hence, the number of electrons and protons in an element is 50.
The neutrons are defined as the proton minus mass number. Hence, the number of neutrons is 120-50=70
Hence, the answer is 50, 50, and 70

1) What is released during respiration?
O Energy
O Food
O
Air
O Glucose
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate). Summary, Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.

A chloroplast converts energy from sunlight into organic matter.
Mitochondria change energy stored in organic compounds into a
usable form. the two statements are ways in which cells get nutrients.
Proteins embedded in the cellular membrane act as ushers. They help carry nutrients from the bloodstream into the cell. Glucose, amino acids, fats, and vitamins use carrier proteins to get inside cells.Onice through the membrane, nutrients play many important roles. Some cells, like muscle fibers, need minerals like calcium to flood the cell to move your arms and legs. Others, like nerve cells, need sodium and potassium to be pumped in and out so your brain can pick up sensory information.Cells use the glucose in your bloodstream to create energy by making ATP, the cellular energy currency. And amino acids are the building blocks for all DNA. When they’re brought into the cell, amino acids help transfer genetic information so cells can replicate.Learn more about cells get nutrients

Answer:
Neither arre correct
Explanation:
Neither Anya nor Braden are correct. This is because if you use 90 degrees, 180 degrees, or even 270 degrees you will not get the exact image, which means that the image will not be found by just a rotation because there will be a curve in the image. You can solve it if you can do 90 degree rotation and translation.

Calculate the volume of a sample of aluminum that has a mass of 3.057 kg. The density of aluminum is 2.70 g/cm3 (taking into consideration the rounded to three significant figures)
Answer:
v = 1130 cm³
Explanation:
Given data:
Volume of sample = ?
Mass of Al sample = 3.057 Kg (3.057 Kg× 1000g/1 Kg = 3057g)
Density of Al sample = 2.70 g/cm³
Solution:
Formula:
d = m/v
d = density
m = mass
v= volume
by putting values
2.70 g/cm³ = 3057g /v
v = 3057g /2.70 g/cm³
v = 1130 cm³
