Reactant X contains 199.3 J of chemical energy. Reactant Y contains 272.3 J of chemical energy. Product W contains 41.9 J of che
telo118 [61]

Answer : The correct option is, 318.1 J

Solution :

The given chemical reaction will be,

X+Y\rightarrow W+Z+Energy

In this reaction, X and Y are the reactants and W and Z are the products.

As we know that the energy remains conserved during the chemical reaction.

So,

Sum of energy of product = Sum of energy of reactant

W+Z+Energy=X+Y\\\\41.9J+Z+111.6J=199.3J+272.3J\\\\Z=318.1J

Therefore, the amount of chemical energy of product Z contain will be, 318.1 J

A motorcyclist changes the velocity of his bike from 20.0 meters/second to 35.0 meters/second under a constant acceleration of 4
mars1129 [50]

The time needed by the bike to reach the final velocity is 3 .75 seconds ,Option C is the write answer.

<h3>What is Velocity ?</h3>

It is defined as the distance covered by an object in a given amount of time. It is a vector quantity , its unit is m/s , km/hr etc.

It is given in the question that

Initial Velocity = 20m/s

Final Velocity = 35m/s

Acceleration = 4m/sq.s

Time = ?

The equation of motion

v = u +at will be used

35 = 20 + 4 * t

15 = 4* t

t = 3.75 seconds

Therefore the time needed by the bike  to reach the final velocity is 3 .75 seconds.

10.0 grams of water are heated during the preparation of a cup of coffee 1.0x 103 j of the heat are added to the water. which is
nirvana33 [79]

<u>Answer:</u> The final temperature of the coffee is 43.9°C

<u>Explanation:</u>

To calculate the final temperature, we use the equation:

q=mC(T_2-T_1)

where,

q = heat released = 1.0\times 10^3J=1000J

m = mass of water = 10.0 grams

C = specific heat capacity of water = 4.184 J/g°C

T_2 = final temperature = ?

T_1 = initial temperature = 20°C

Putting values in above equation, we get:

1000J=10.0g\times 4.184J/g^oC\times (T_2-20)\\\\T_2=43.9^oC

Hence, the final temperature of the coffee is 43.9°C

What are all the possible masses of cl2 molecules that are made when two chlorine atoms bond together?
Pavel [41]

The masses of the 2 most common isotopes of Cl are 35 and 37. Therefore we can formulate 3 possible masses of Cl2:

<span>
35 + 35 = 70 
35 + 37 = 72 
37 + 37 = 74 

<span>However, Cl 35 is the most common isotope of chlorine of the two therefore it is the most probable that two Cl 35 atoms will combine, so 70 is the most common among all.

Rank the following groups in order of decreasing priority: A. bondCtbondCH B. bondCH(CH3)2 C. bondCH2CH3 D. bondCHdbondCH2
Lelu [443]

Answer:

(CH2)3CH3 > CH2CH2CH3 > CH2CH3 > CH3

Explanation:

Giving the following ; CH3, CH2CH3, CH2CH2CH3, (CH2)3CH3

Priority increases as the number of CH2 group increases and vice versa, as such the one with more CH2 group will be the highest priority and the least compound with the small CH2 group attached, will have the smallest priority.

The arrangement is as follows ; (CH2)3CH3 > CH2CH2CH3 > CH2CH3 > CH3
