Can somebody help me with my science HW
The speed at which a nitrogen molecule’s particles are moving increases. What will happen to the thermal energy of this molecule?
A) The thermal energy of the molecule will increase.
B) The thermal energy of the molecule will not change, but its mass will change.
C) The thermal energy of the molecule will not change, and its mass will remain the same.
D) The thermal energy of the molecule will decrease.
Answer
The thermal energy of the molecule will increase.
Explanation:
Increasing the speed at which the particles are moving cause atoms and molecules to move faster and collide with each other. This increases the thermal energy.
If you freeze 5 mL of water into ice and then let it melt, how much water will you have?
None
5 mL
10 mL
Unlimited
Answer:
5 MLS
Explanation:
This is true because energy can't be created nor destroyed. So If you have
5 mills of water. you will always have 5 mills of water. The reason for this is because the water just changes state from a liquid to a solid. If you turn it back into a Liquid. You will have the same amount.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
Draw and use algebra tiles to solve the equation. 2x + 3 = 5 x =
Answer:
1 is the correct answer:)
Subtract
3
33
from both sides of the equation
2+3=5
Simplify
Subtract
5
5x5x
from both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify
than you will have 1.
Which statement about exothermic reactions is true?
Responses
The reactants create energy to form products.
Energy from an outside source is continuously being added.
More heat is given off than is put into the reaction.
The reaction container always feels cold.
Answer:An exothermic reaction may be defined as a type of reaction in which energy is significantly liberated in the form of heat or light. In such types of reactions, energy is generally transferred into the surroundings rather than utilized from the surroundings.
The option "energy from an outside source is continuously being added" represents an endothermic reaction in which heat or light energy is externally been provided. The option "more heat is given off than is put into the reaction" is not absolutely true because exothermic reactions liberate energy but it does not matter if it is higher or lower than that of being put into the reaction.
Therefore, the reactants have more heat energy than the products is a statement that is true about exothermic reactions. Thus, the correct option for this question is C.
Explanation:
you welcome
Energy from outside sources is continuously being added, since its an exothermic reaction it always focusses on releasing large amount of energy upon activation and combustion.
It cuts off on giving energy back to its surrounding unlike endothermic reaction where the generated energy is given back to the environment to restore its energy levels.
Therefore, it makes it clear that exothermic reaction is a type of reaction that uses combustion to gather the energy lying around in the surrounding to generate large amount of energy and heat and keeps on producing heat until and unless there is energy in surrounding.

Answer:
Here at science made simple we are keen to inspire not only the next generation of scientists but also the next generation of science communicators. Supporting work experience students each year is an important part of what we do. Our work experience students get a chance to see a range of the activities that science made simple is involved with and we always set them challenge to produce some science communication themselves, whether designing a demo, delivering a short presentation or, in this case, writing a blogpost that includes all of these!
We hope you enjoy this from one of our latest work experience students, Bilaal, we loved having him in the office and think he’s got a promising career ahead of him.

This blogpost looks at two types of reactions: exothermic and endothermic. We’ll also be looking at reversible reactions– reactions in which the products can react to remake the original reactants. Plus, a great demonstration of an exothermic reaction.

Explanation:
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
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.
