Given the equation: I + I → I2 + 35 kcal This equation shows that the formation of an iodine molecule is an A) endothermic process in which energy is absorbed B) exothermic process in which energy is released C) exothermic process in which energy is absorbed D) endothermic process in which energy is released

Answers

Answer:

A) endothermic process in which energy is absorbed

Step-by-step explanation:

A thermochemical reaction equation is a chemical reaction equation in which the enthalpy of reaction is written after the symbols of reactants and products.

The importance of thermochemical reaction equations is that they show us whether energy was absorbed or evolved in a reaction as well as the magnitude of energy absorbed or evolved.

When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. When the enthalpy of reaction is negative, the reaction is exothermic and energy is evolved or released.

The enthalpy of the reaction  I + I → I2 + 35 kcal is positive hence the reaction is an endothermic process in which energy is absorbed.

The equation shows that the formation of an iodine molecule is an A. endothermic process in which energy is absorbed.

What is an endothermic process?

It should be noted that an endothermic process is where heat is transferred from the surroundings to the systems. In this case, the system has gained heat from the surroundings.

The change in enthalpy, delta H is positive for an endothermic process. When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. The enthalpy of the reaction is positive as illustrated in this case.

find the measure of the arc or angle indicated. assume that lines which appear tangent are tangent. just enter the number.

Answers

Answer:

C. 60°

Step-by-step explanation:

The vertical angle formed inside a circle when two chords intersect each other is equal to half the sum of the measures of the intercepted arcs, based on the intersecting chords angle measure theorem.

Thus:

90° = ½(120° + arc TA)

Multiply both sides by 2

2*90 = 120 + arc TA

180 = 120 + arc TA

Subtract 120 from each side

180 - 120 = arc TA

60° = arc TA

Arc TA = 60°

Determine the equation of the line parallel to the line y=34x+2
y=3/4x+2 that passes through the point (4, -3).

Answers

Answer:

y = 34x - 139 (y = 34x + 2)

y = [tex]\frac{3}{4}[/tex]x - 6 (y = 3/4x +2)

Step-by-step explanation:

(I'm not sure if the two equations were the same or not, but I provided the answers just in case.) Parallel lines are two lines that have the same plane and slope but never intersect. To find the equation, use the formula y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])

A baker can decorate one cake in
hour.
What is the total number of hours the baker needs to decorate 4 cakes?

Answers

Answer:

4 hours

Step-by-step explanation:

It takes one hour to make one cake, so we can put that as a ratio of 1:1.

4 cakes means you multiplied one side by 4, as it is 4 cakes and not one, so you multiply the time by 4 too.

4 hours

Answer:

4 hours is needed for the baker to decorate 4 cakes.

If I’m understanding this problem correctly (I believe it wants me to isolate the group), we’re taking 27% (0.27) of the total men who answered the survey which equated to 45% (0.45)

First we’ll change 0.27 and 0.45 to 27 and 45. So, if 45 is our maximum, then if we divide 27 by 45, we’ll get the value 0.6–> if we multiply that by 100, we’ll get 60%.

Thus, 60% of men within that gender group preferred suspense movies.

Step-by-step explanation:

Given :

___________ Sample size __ sample mean

Treatment 1 ____ 5 _______ 4

Treatment 2 ____ 10 ______ 8

Treatment 3 ____ 5 _______ 9

Sample size = (5 + 10 + 5). = 20

Overall mean = ((5*4). + (10*8) + (5*9)) / 20

Overall mean = (20 + 80 + 45) / 20

permutation or a combination?
(b) If the coach wanted to choose her 11 starters at random by drawing names from a hat, how many possible groups of 11 starters could she choose?
(c) The coach wants to make sure there is exactly one goalie on the field. How many ways can the
coach choose a lineup of 11 players if exactly 1 player must be a goalie?

Step-by-step explanation:

A.)

Choosing 11 players from 20 ; here the order in which the players are chosen does not matter, hence it is a combination problem.

2.)

Using nCr

n = 20 ; selection, r = 11

nCr = n! / (n-r)!r!

20C11 = 20! / 9!11!

20C11 = 167960

The measure of ∠BCF is 60°, and the measure of ∠FCG is 35°. Which equation can you use to find the measure of ∠BCG?

Answers

Answer:

x =  ∠BCF+ ∠FCG

Step-by-step explanation:

According to the given measure, we can say that, line Fc bisects  ∠BCF and  ∠FCG and the sum of  ∠BCF and  ∠FCG is  ∠BCG. Mathematically;

∠BCF+ ∠FCG =  ∠BCG

Given

∠BCG = 60degrees

∠FCG = 35degrees

Let x be equal to  ∠BCG

Hence the required equation will be;

∠BCF+ ∠FCG =x

Swap sides

x =  ∠BCF+ ∠FCG
