Explanation:
Water is less dense as ice than liquid
Your answer:
true
false
Answer:
Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
Explanation:
Answer:
false

EASYYYYYYYYYYY A batter hits two balls during practice. Ball A travels 10 meters, while ball B travels 12 meters. The batter decides to hit ball A with less force. How will this change the motion of ball B?
The motion of ball B will increase.
The motion of ball B will decrease.
The motion of ball B will stay the same.
The motion of ball B will become the same as ball A.
Answer:
The motion of ball B will increase
Explanation:
Because if you hit ball A with less force than ball B then that means that ball B will go faster because you had hit ball A will less force witch will not be as faster as ball B.
Answer:
The first one

So im confused i don't know what im supposed to do here
So I believe you are supposed to take notes based on the guiding questions (the questions on the side).
Answer:
save your notes in a google drive folder then go back to canvas and click on the "google drive" tab then scroll down and once you see the name of the folder you saved your notes in, click on it then hit submit
Explanation:
How are the scientific method and the engineering method similar?
Both methods identify failure points.
Both methods construct a hypothesis.
Both methods focus on designing things.
Both methods work on finding solutions to problems.
The answer is Both methods work on finding solutions to problems. Because the science is trying to get the right thing and engineering is trying to solve the problem and get right thing and is the same with the science

Water’s chemical formula is . One atom of bonded to two atoms of . The hydrogen atoms are to one side of the oxygen atom, resulting in a water molecule having a positive charge on the side where the hydrogens reside and a negative charge on the other side, where the oxygen atom resides. This separation
of charge on of the molecule is called

Can someone please help me with this it's for a grade.
Answer:
The Answer is 'D'
Explanation:
The diagram on the down side shows the behavior of the particles of a liquid so I suppose it is the ocean. While the top diagram shows the behavior of the particles of a gas so I am sure it's the air. Therefore I chose the last diagram because it describes exactly how you wanted in the question, which is the Ocean's water evaporating to become gas or the 'air' as we say
Thank you and I hope you like this answer!

When vinegar, an acid, is mixed with baking soda, a base, the reaction is similar to the reaction of Alka-Seltzer and water; a salt, water and carbon dioxide are produced. In two or more complete sentences, describe how your knowledge of balancing chemical equations can help you to determine the missing compound.
NaHCO3 + HC2H3O2 ⟶ ________ + H2O + CO2
Answer:
1) Carbon dioxide is the name of the gas.
2) The missing compound is
Step-by-step explanation:
1)When ever an acid reacts with baking soda brisk effervescence of carbon dioxide gas are released.
So, when citric acid reacts with baking soda it gives salt of sodium citrate , water and carbon dioxide gas.
2)
According to law of conservation of mass:
Number of atoms on reactant sides are equal to the number of atoms on product side.
Number of atoms of an element on left hand side is equal to the number of atoms of that same element on the right hand side.
Number of hydrogen atom on reactant side = 5
Number of hydrogen atom on product side = 2+ x
5 = 2+x
x = 3
Number of carbon atom on reactant side = 3
Number of carbon atom on product side = 1 + y
3 = 1 + y
y = 2
Number of oxygen atom on reactant side = 5
Number of oxygen atom on product side = z + 3
5 = z + 3
x = 2
Number of sodium atom on reactant side = 1
Number of oxygen atom on product side = a
1 = a
The missing compound is
Explanation:
Answer:
1) Carbon dioxide is the name of the gas.
2) The missing compound is H3C2O2Na

It is important that engineers build a structure that is safe. What do they look for when testing their designs?
Failure points
Fair tests
Prototypes
Variables
Answer:
Failure Points
