Use the incomplete reaction to complete the activity. Ba(ClO3)2 → ____ + 3O2 In one or two sentences, identify the type of reaction that is occurring and identify the other product. Based on the subscripts of the elements in the other product and the fact that chlorine has seven valence electrons, determine the number of electrons in barium’s (Ba) outer shell.

Answers

Answer 1

The missing product of the reaction is BaCl2 and we can see that barium has two electrons on its outermost shell.

The complete reaction is  Ba(ClO3)2 → BaCl2 +  3O2. From the reaction equation, we can see that the missing product is BaCl2. The compound is composed of one barium atom and two chlorine atoms.

Since chlorine has seven valence electrons, it means that it requires two electrons from barium to complete its octet in BaCl2. This now means that barium has two electrons in its outermost shell.

Answer:

56/100

Step-by-step explanation:

The decimal place has 2 digits which indicates two zeros. So the denominator will be 100. And 56 will become the numerator.

Answer: 51/90

First set x equal to the decimal (we will solve for x):
x = 0.5666666666...

Now find 10x (we want to get the recurring digit right after the decimal point):
10x = 5.66666666666...

Next we can subtract x from 10x:
9x = 5.1

We can now get x by dividing both sides by 9:
x = 5.1/9

We can’t have a decimal in a fraction so we can multiply the top and bottom numbers by 10:
x = 51/90

Answers:

x = 40 and y = 40

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

Explanation:

The three angles involving x add up to 180 since they form a straight line or straight angle.

3x+0.5x+x = 180

4.5x = 180

x = 180/(4.5)

x = 40

Then note how the 0.5x and 0.5y angles are vertical angle pairs. Vertical angles form when we have two lines cross to form an X shape, and vertical angles are always opposite one another. Also, vertical angles are always the same measure.

0.5x = 0.5y

x = y

40 = y

y = 40

In the second step, I multiplied both sides by 2. Then I plugged in x = 40 we found earlier.

Write an equation in​ slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation.

Answers

To find the parallel :

First of all, Parallel equations should have the same slope and a different y-intercept!

Take the equation of a linear function : y = mx + b, the slope here is m and the y intercept is b.

When we’re given a point (x,y), we write our equation in the y = mx + b form, then substitute the given point for (x,y) and solve for B!

Practice

We already know our equation will be in the form y = mx + b

And we also know that the slope will be the same : m = 4/7

So y = 4/7x + b

Lets find b !

The line passes through the point (0,0) of origin :

0 = 4/7*0 + b

b = 0

So the y intercept is b = 0

And finally the equation will be :

y = 4/7x

Everyday Jayden saves a half of his lunch money. By Friday he has $ 600. How much money does he get daily for lunch?​

The amount he gets for lunch is an illustration of mean and averages.

He gets for lunch is $240 daily

Represent the amount he gets for lunch each day be x.

So, the amount saved each day is x/2

From Monday to Friday, the total savings would be 5x/2

So, we have:

[tex]\mathbf{\frac{5x}{2} = \$600}[/tex]

Multiply both sides by 2

[tex]\mathbf{5x = \$1200}[/tex]

Divide both sides by 5

[tex]\mathbf{x = \$240}[/tex]

The price of Stock A at 9 AM was $12.73. Since then, the price has been increasing at the rate of $0.06 per hour. At noon, the price of Stock B was 13.48. It begins to decrease at the rate of $0.14 per hour. If the stocks continue to increase and decrease at the same rates, in how many hours will the prices of the stocks be the same?

Answers

Answer:

Let the hours when they equalize=h, then we have:

12.25 + .13h=13 - .09h

.13h + .09h=13 - 12.25

.22h=.75 divide both sides by .22

h=.75/.22

h=3 9/22, hours, when they will equalize.

The stock prices will be the same in 3.4 hours.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

At 9 a.m., the price of Stock A was $12.73. Since then, the price has risen at a pace of $0.06 per hour. Stock B was trading at 13.48 at midday. It starts to fall at a pace of $0.14 each hour.

Let's assume the hours would be h when to equalize,

As per the given question, we can write the equation as:

12.25 + 0.13h = 13 - 0.09h

Rearrange the terms of h in the above equation,

0.13h + 0.09h = 13 - 12.25

Combine the likewise terms in the above equation,

0.22h = 0.75

Divide both sides by 0.22

h = 0.75/0.22

h = 3.4

Thus, the stock prices will be the same in 3.4 hours.

Answer:

Step-by-step explanation: We can solve this in two ways:  Solve the equations directly, or graph the lines and find the point they intersect (which will be the only point at which they are equal.

Solve The Equations:

y = 2x+9

y = -x-3

Set them equal to each other (to find x such that both equations will return the same value for y).

-x-3 = 2x + 9

-3x = 12

x = -4

Use x=-4 in either equation to find y:

y = -x-3

y = -(-4)-3

y = 1

===

The point is (-4,1).  That is the point that satisfies both equations:

1)  y = 2x+9

    y = 2(-4)+9

   y = 1, and

2)  y = -x-3

    y = -(-4)-3

    y = 1

=====

We can also solve by graphing and finding the point at which the two lines intersect.  A graph is attached.

=========

0.5p + 0.75m <= 225

p = m + 50

-------------------

Substitute for "p" and solve for "m"::

0.5(m+50) + 0.75m <= 255

0.5m + 25 + 0.75m <= 255

2.25m <= 325

Answer:

Answer choice C should be more Resonable.

Step-by-step explanation: It is very obvious

because you are spending less than $225 and when it says at least 50 more it means that 50 is the bare minimum so the ideal choice is 150 more apples than oranges and likely the oranges will be 100 and aples will be 250 and you won't spend over $225.
