Where is the word problems? Like the problems that you have to put it in.
Explanation:
what is the reason of the gas pressure.
Answer:
The rapid motion and collisions of molecules with the walls of the container causes pressure (force on a unit area). Pressure is proportional to the number of molecular collisions and the force of the collisions in a particular area. The more collisions of gas molecules with the walls, the higher the pressure

A carbon atom that is a part of your body could very well have been part of a dinosaur millions of years ago. What BEST explains this?
A The carbon atoms that are found in current living things are developed when the organism is produced.
B Carbon atoms found in current living things are the same carbon atoms that have always been a part of living things, they are just recycled.
C This could not be explained because carbon found in our bodies could not have a part of any previous organism.
D Carbon atoms are genetically passed through the evolution of organism.
Answer:
B - Carbon atoms found in current living things are the same carbon atoms that have always been a part of living things, they are just recycled.
Carbon atoms found in current living things are the same carbon atoms that have always been a part of living things, they are just recycled. Hence, option B is correct.
What is an atom?An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons.

describe a procedure to remove the water from the mixture that passes through the filter and collects in the beaker.
Answer:
The procedure is Filtration
Explanation:
Filtration is a process that is use to separate insoluble solid from liquid for example Salt and water.
This process uses filter paper which is placed inside a funnel and then placed inside a beaker.
The mixture of sand and water is poured into the the filter paper and water then drains out down to the funnel and the beaker.
The solid part remain at the filter paper and it is called the residue and the water is the filtrate.

If an atom has 18 protons,17 neutrons,and 19 electrons what is the atom electrical charge?
A +2
B +1
C -2
D-1
Answer:
D: -1
Explanation:
18 protons so +18
19 electrons -19
neutrons dont count there neutral
-19+18= -1
Answer: D: -1
Explanation: All protons have a +1 charge, neutrons are neutral, and electron have a -1 charge. Therefore it can be concluded that if the atom has 18 protons which all have +1 charge and 19 electrons which all have -1 charge, then the atom will have a -1 charge since 18-19=-1

Explanation:
what is the density of the football
A student finds a rock on the way to school. In the laboratory he determines that the volume of the rock by placing the rock in a graduated cylinder with 50 mL of water and watched the water rise to 72.7 mL. The student determined the mass is 39.943 g through the use of a triple beam balance. What is the density of the rock?
Answer:
1.76 g/mL
Explanation:
You need to find the volume. You can do this by subtracting the volume of the water and the rock by the volume of the water.
72.7 mL - 50 mL = 22.7 mL
Now that you have volume, divide the mass by the volume to find the density.
39.943 g/22.7 mL = 1.76 g/mL
A graduated cylinder is filled with 54.32 cm3 of water. An irregular solid made of iron is carefully placed into the graduated cylinder. The new volume recorded on the graduated cylinder is 57.65 cm3. The density of iron is known to be 7.874 g/cm³. What is the mass in grams of the irregular solid made of iron?
Answer:
The answer is 26.22 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
density of iron = 7.874 g/cm³
volume = final volume of water - initial volume of water
volume = 57.65 - 54.32 = 3.33 mL
We have
mass = 7.874 × 3.33 = 26.22042
We have the final answer as
26.22 gHope this helps you
