True or false When heat flows to an object, it can change states.
Answers
Answer: True
Explanation:
The matter exists as solid, liquid or gas. These are called the states of matter. The change of matter from one state to another can be achieved by heating or cooling.
The solid state can be converted into liquid state by providing heat to solid. The heat will make the particles move farther, resulting into liquid state.
Similarly when liquid state is provided heat, it changes to gaseous state. The heat will make the particles move much more faster.
Thus the statement that when heat flows to an object, it can change states is True.

Marissa uses her bicycle to do a morning paper route. Starting at her home, she travels 3 km North, then 1 km East, then 3 km North, and lastly 1 km West. She completes the root in 1.5 hours. a. What is your displacement in regards to her home?
b. What is her velocity?
Answers
a. displacement = 6 km
b. velocity = 4 km/h
Further explanationGiven
a morning paper route
Required
displacement
velocity
Solution
Displacement is a vector quantity that shows changes in the position of objects in a certain interval of time. Displacement has magnitude and direction
Can be simplified displacement = distanced traveled from starting point to ending point
a. Since we only consider the starting point and the end point, we just need to add up the distances to the north
3 km + 3 km = 6 km
b. Velocity = displacement changes with time
[tex]\tt v=\dfrac{d}{t}=\dfrac{6~km}{1.5}=4~km/h[/tex]
Which statement about anabolism is true?
A. In anabolism, energy is released.
B. In anabolism, energy is absorbed.
C. In anabolism, energy is absorbed and then released.
O
D. In anabolism, energy is released and then absorbed.
Answers
Answer:
i would say B? Im sorry if im wrong
Explanation:
i think that because Catabolic reactions release energy, while anabolic reactions use up energy. Anabolism is the opposite of catabolism.
Answer:
B) In anabolism, energy is absorbed.
Why do longer wavelengths are considered to have lower frequencies? Make it as elaborate as possible. :D
Answers
Answer:
Longer wavelengths self means by it's name that the distance between the trough and crust are lesser than that of shorter wavelengths!
The word Lower frequency implies lower energy, thus light cannot easily penetrate the EM wave to excite electrons.
Examples of EM waves with longer wavelength :
Radiowaves, microwaves, etc..
Atoms combine in whole-numbcher ratios.

Why do positive ions have a positive charge?
Answers
Answer:
Ions form when atoms gain or lose electrons. Since electrons are negatively charged, an atom that loses one or more electrons will become positively charged; an atom that gains one or more electrons becomes negatively charged. Ionic bonding is the attraction between positively- and negatively-charged ions.

aluminum metal reacts with aqueous nickel II sulfate to produce aqueous aluminum sulfate and nickel as a precipitate. in this reaction 108 grams of aluminum were combined with 464 grams of nickel II sulfate to produce 274 grams of aluminum sulfate.
Answers
The question is incomplete, the complete question is;
In this stoichiometry problem, determine the percentage yield:
Excess aluminum metal reacts with aqueous nickel(II) sulfate to produce aqueous aluminum sulfate and nickel as a precipitate. In this reaction 108 g of aluminum were combined with 464 g of nickel(II) sulfate to produce 274 g of aluminum sulfate.
Answer:
80%
Explanation:
The correct equation for this reaction is;
2Al(s) + 3NiSO4(aq) --------> Al2(SO4)3 + 3Ni(s)
We already know that Al is in excess then NiSO4 is the limiting reactant.
Hence, Number of moles in 464 g of NiSO4 = mass/ molar mass
Molar mass of NiSO4 = 155 g/mol
Number of moles = 464g/155g/mol = 2.99 moles
Number of moles of Al2(SO4)3 = mass/molar mass
molar mass = 342 g/mol
So, Number of moles = 274g/342g/mol = 0.8 moles
Given the stoichiometric reaction equation;
3 moles of NiSO4 yields 1 mole of Al2(SO4)3
2.99 moles of NiSO4 yields 2.99 * 1/3 = 1 mole of Al2(SO4)3
percentage yield is given by; actual yield/ theoretical yield * 100/1
actual yield = 0.8 moles of Al2(SO4)3
Theoretical yield = 1 mole of Al2(SO4)3
Hence;
% yield = 0.8/1 * 100 = 80%
