I think the answer could be B.

It's been a while since I've learned anything about this but here's what I know, hopefully it will help you:
Waves are created by wind but dragging across the top of the ocean and then a force pulling the water back down. The question is asking how energy transfers through a wave though and that leads me to guess that the answer is D. Water particles are set in a circular motion. Water moves in a circular motion to the best of my knowledge.

Hope this helps! (:

B. heat always flows from warmer objects to cooler objects

Answer is b
it will flow from the warm and then to the cooler trying to balance out the energy and heat

Real world Examples of inertia

Answers

~One real life example of inertia is when a hockey-puck continues to slide across the ice until its acted upon by an outside force.

These models show the electron structures of two different nonmetal elements.Which element is likely more reactive, and why?

A.) Element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table.

B.) Element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table.

C.) Element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons.

D.) Element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

Answers

Answer: Option (D) is the correct answer.

Explanation:

Valence shell is the shell present on the outermost core of an atom and electrons present in the valence shell are known as valence electrons.

If an atom has completely filled valence shell then it means the atom is not reactive in nature because it is already stable.

But when an atom has less than eight electrons in its valence shell then it means to attain stability the atom will readily attract electrons towards itself.

As the given element 1 has 8 electrons in its valence shell. Hence, it is not reactive in nature but element 2 has 6 valence electrons. So, in order to attain stability element 2 will readily attract 2 electrons from a donor atom.

Thus, we can conclude that element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

Its D

Classify the chemical equations as being balanced or not balanced

Answers

Answer: Two of them are balanced and two of them are unbalanced.

Explanation:

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on the product side. These equations follow law of conservation of mass.

An unbalanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is not equal to the total number of individual atoms on the product side. These equations does not follow law of conservation of mass.

For the given chemical equations:

Equation 1: $2CO+2NO\rightarrow 2CO_2+N_2$

As, number of carbon, nitrogen and oxygen atoms on the reactant side is equal to the number of carbon, nitrogen and oxygen atoms on the product side. Thus, this is a balanced chemical equation.

Equation 2: $6CO_2+6H_2O\rightarrow C_6H_(12)O_6+O_2$

As, number of oxygen atoms on the reactant side is not equal to the number of oxygen atoms on the product side. Thus, this is not a balanced chemical equation.

Equation 3: $H_2CO_3\rightarrow H_2O+CO_2$

As, number of carbon, nitrogen and oxygen atoms on the reactant side is equal to the number of carbon, nitrogen and oxygen atoms on the product side. Thus, this is a balanced chemical equation.

Equation 4: $2Cu+O_2\rightarrow CuO$

As, number of oxygen and copper atoms on the reactant side is not equal to the number of oxygen and copper atoms on the product side. Thus, this is not a balanced chemical equation

Hence, two of the equations are balanced and two are unbalanced.

1,2,4 are not balanced, 3 is balanced
