Answer:
The correct answer will be "18.25 g".
Explanation:
The given values are:
Specific heat,
C = 0.45 J/g･°C
Heat involved,
q = 801 J
Temperature,
ΔT = 120.0°C-22.5°C
= 97.5°C
As we know,
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
Answer:
Reaction will proceed towards forward direction.
Explanation:
Balanced reaction: 
Reaction quotient (
) for this reaction is represented as:
![Q_{c}=\frac{[COCl_{2}]}{[CO][Cl_{2}]}](https://tex.z-dn.net/?f=Q_%7Bc%7D%3D%5Cfrac%7B%5BCOCl_%7B2%7D%5D%7D%7B%5BCO%5D%5BCl_%7B2%7D%5D%7D)
Here, [CO] = [
] = 0.010 M and [
] = 0.070 M
So, 
= 700
As > 
therefore reaction will proceed towards forward direction i.e. more will be produced.

Answer:
C) ball rollinflown a hill
Explanation:
The question asks to identify the endothermic process in the list of options. By way of elimination, we have;
A) condensation of water on a wind shield of a car
Condensation is an exothermic process. That is, heat is given out as the gases change into the liquid state of matter.
B) formation of copper
This is an exothermic process. Capture of electrons by a cation is always exothermic.
C) ball rollinflown a hill
This is the correct option. Energy is absorbed by the ball as it moves on the hill
D) formation of ice from liquid water
Freezing is an example of exothermic reaction. Heat is given off to the surroundings.
E) oxide from copper and oxygen
Formation of metal oxides and most reactions involving oxygen are exothermic reactions,
Answer:
two
Explanation:
When two distinct elements are chemically combined, chemical bonds form between their atoms. the result is called a chemical compound
