What is the density of a liquid that has a mass of 27g and a volume of 30mL?
Answers
-Carrie
A liquid with a mass of 27g and a volume of 30 ml has a density is 0.9 g/ml.
What is the density of a liquid?You follow the same procedure as you would for a solid to determine the density of a liquid. Determine the fluid's volume, mass it, and then divide mass by volume.
Weigh the fluid in the container, pour it out, weigh the empty container, and then subtract the empty container's mass from the mass of the filled container to get the fluid's mass.
Calculate the substance's density in mg/mL, it is 1000 mg/mL for water. You may calculate the quantity in milliliters by dividing the milligram amount by the density.
Therefore, one of the most important ones is that a substance's density will influence whether it will float on another, 0.9 g/ml is the density of a liquid.

How is the form of energy being changed when a student uses an electric sharpener to sharpen a pencil?
from mechanical to electrical
from electrical to mechanical
from thermal to mechanical
from magnetic to electrical
Answers
Answer:
B
Explanation:
Because the sharpener is attached to an electrical outlet
When a student uses an electric sharpener to sharpen a pencil then from electrical energy to mechanical energy. Therefore, option (B) is correct.
What is mechanical energy?Mechanical energy can be defined as the addition of kinetic energy and potential energy that is used to perform work. The total mechanical energy is conserved when the forces performing work are conservative in nature.
The principle of conservation of mechanical energy can be described as when an isolated system is under the influence of conservative forces, then the mechanical energy is constant. If a body moves in the opposite direction of a net force, the potential energy will increase and the speed of the object changes, the kinetic energy also changes.
Many devices are used to transform mechanical energy to or from other forms of energy, such as an electric motor converts electrical energy to mechanical energy,
An electric sharpener converts mechanical energy into electrical energy. Therefore, option (B) is correct.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

can copper block be separated? why or why not?
Is this considered a pure substance or a mixture?
Answers
No, a copper block cannot be separated.
A copper block cannot be separated because it is made up of only copper atoms which are only one type of molecule. It is a tightly bound structure of copper atoms.
A pure substance means a substance that is free from any kind of mixture and contains only one kind of particle are pure substances. A mixture is composed of one or more pure substances in different compositions. So a copper block is a pure substance and not a mixture.

Part 3: Writing to the People of Westfield
Dr. Yung wants you to explain what the reddish-brown substance is to the people of Westfield. As you write your argument, remember to:
state your claim about the identity of the reddish-brown substance.
use evidence from both your observations and the atomic-scale models to support your claim.
include the vocabulary words listed below in your argument.
Chapter 1 Question: What is the reddish-brown substance in the water?
Claim 1: The reddish-brown substance is the same as the substance that makes up the pipes.
Claim 2: The reddish-brown substance is the same substance as the fertilizer.
Claim 3: The reddish-brown substance is not the same as either the fertilizer or the substance that makes up the pipes.
Word bank: atom, model, property, substance
Answers
Answer:
Dear People of Westfield,
As you may be aware, there has been a lot of concern about the reddish-brown substance found in the water supply. After conducting extensive research and analysis, I am here to share my findings with you.
Based on my observations and the atomic-scale models, I can confidently state that the reddish-brown substance is not the same as either the fertilizer or the substance that makes up the pipes. In fact, the reddish-brown substance has its own unique set of properties that distinguish it from these other substances.
One of the key pieces of evidence supporting this claim is the atomic-scale model of the reddish-brown substance. This model shows that the substance is made up of its own distinct atoms arranged in a specific way. These atoms have unique properties, such as their size and charge, that differentiate them from the atoms that make up the fertilizer and the pipes.
Furthermore, my observations of the reddish-brown substance also support this claim. I have noticed that the substance behaves differently than both the fertilizer and the pipe material. For example, the substance dissolves at a different rate and reacts differently to various chemicals.
In conclusion, it is clear that the reddish-brown substance in the water supply is its own unique substance, with its own distinct properties and atomic makeup. It is not the same as either the fertilizer or the substance that makes up the pipes. I hope that this explanation provides some clarity and reassurance to the people of Westfield.

I am writing to address the recent concerns about the reddish-brown substance found in your water. After careful observation and analysis, I have come to the conclusion that the reddish-brown substance is not the same as either the fertilizer or the substance that makes up the pipes.
My claim is based on the evidence from both my observations and the atomic-scale models. The atomic-scale models show that every substance is made up of atoms that have unique properties. These properties determine the characteristics of the substance. After analyzing the reddish-brown substance, I found that its properties are different from both the fertilizer and the substance that makes up the pipes.
Furthermore, the reddish-brown substance has a unique set of properties that are not found in either the fertilizer or the substance that makes up the pipes. These properties include its reddish-brown color, its texture, and its chemical composition. These properties are consistent with a different substance that is not related to either the fertilizer or the substance that makes up the pipes.
In conclusion, I believe that the reddish-brown substance is not the same as either the fertilizer or the substance that makes up the pipes. My claim is based on the evidence from both my observations and the atomic-scale models. The properties of the reddish-brown substance are unique and do not match those of either the fertilizer or the substance that makes up the pipes.
