Answer:

Chemical

Explanation:

A chemical reaction is the rearrangement of atoms by breaking and reforming chemical bonds. This can further be explained by the following chemical reaction:

Acid react with a base to produce salt and water. This can be seen when hydrochloric acid (HCl) react with sodium hydroxide according to the balanced equation:

HCl + NaOH —> NaCl + H2O

The above is simply a chemical reaction as the bond in HCl breaks up and likewise the bond in NaOH. The atoms are rearranged, forming a new bond by producing salt (NaCl) and water (H2O)

Here, the definition is given and asked for a word that is defined.

The rearrangement of atoms by breaking and reforming chemical bonds is called a chemical reaction.

Hence, "chemical" is the missing word.

A <u>chemical</u> reaction is the rearrangement of atoms by breaking and reforming chemical bonds.

Which statement best describes how chemical equations demonstrate conservation of mass?

scoray [572]

Answer:

Explanation:

Let's just get the answer and then show why the others are wrong.

The answer is C.

The number of reactants and Products need not be the same

C3H8 + 5O2 ===> 3CO2 + 4H2O

The reactants = 1 + 5 = 6

The products = 3 + 4 = 7

So A is incorrect.

================

B is saying that

C3H8 + 5O2 ===> C3H8 + 5O2

The answer is obviously not B

======================

C8H18(l) + O2(g) ==> CO2(g) + H2O(g) unbalanced

Gasoline is a liquid. All the rest are gases. D is wrong.

=================

C is correct

The left side has

3 Cs

8 Hs

and 10 Os

The right side has

3Cs

8Hs

10 Os

What it means that [If x is a factor of p(x), what is the value of k?]

kompoz [17]

Answer:

$k = -4$

Explanation:

Given

$P(x) = (3x^2 - 5)(x + k) - 20$

x is a factor

Required

Solve for k

x is a factor means that the polynomial can be divided successfully by x.

In other words, x is a zero of the polynomial.

i.e.

$x = 0$ and $P(x) = 0$

Substitute 0 for x in P(x)

$P(x) = (3x^2 - 5)(x + k) - 20$

$P(x) = (3*0^2 - 5)(0 + k) - 20$

$P(x) = (0- 5)(k) - 20$

$P(x) = (-5)(k) - 20$

$P(x) = -5k - 20$

Substitute 0 for P(x)

$0 = -5k - 20$

Collect Like Terms

$5k = - 20$

Divide both sides by 5

$k = -4$

Lesson 6 homework practice use the pythagorean theorem answer key

Pythagorean theorem should be used to determine the length of any of the three sides of a right-angled triangle.

<h3>What is Pythagorean Theorem?</h3>

Pythagorean theorem can be defined as a fundamental mathematical equation in Euclidean geometry and it can be used to determine the length of any of the three (3) sides of a right-angled triangle.

Mathematically, Pythagorean's Theorem is given by this formula:

c² = a² + b²

<u>Where:</u>

c is the hypotenuse.

a is the adjacent side.

b is the opposite side.

<u>For example:</u>

c² = 3² + 4²

c² = 9 + 16

c² = 25

c = √25

c = 5 units.
