Answer:
The heat of reaction is the energy that is released or absorbed when chemicals are transformed in a chemical reaction. It describes the change of the energy content when reactants are converted into products.
Explanation:
Yeah, that would confuse me a bit but then you read it and then you will get that answer above! Have a great rest of your day!
Answer:
450g of coke (C)
Explanation:
Step 1:
The balanced equation for the reaction is given below:
3C(s) + 2SO2(g) —> CS2(s) + 2CO2(g)
Step 2:
Determination of the mass of C that reacted and the mass of CS2 produced from the balanced equation.
This is illustrated below:
Molar Mass of C = 12g/mol
Mass of C from the balanced equation = 3 x 12 = 36g
Molar Mass of CS2 = 12 + (32x2) = 12 + 64 = 76g/mol.
From the balanced equation above, 36g of C reacted to produce 76g of CS2.
Step 3:
Determination of the mass of C required to produce 950g of CS2. This is illustrated below:
From the balanced equation above, 36g of C reacted to produce 76g of CS2.
Therefore, Xg of C will react to produce 950g of CS2 i.e
Xg of C = (36 x 950)/76
Xg of C = 450g
From the calculations made above, 450g of coke (C) is needed to produce 950g of CS2.
Answer:
<h3><em>A is most likely your correct answer</em></h3>
Explanation:
A. Hills Covered with dry brush- this is most likely correct
b. Hills covered in lush grass- incorrect, because it is LUSH grass which would require lots of rain.
c. Flat lands with little grass- incorrect because grasslands DO have lots of grass.
D- incorrect because grasslands typically do NOT have rocky mountains <u>but are generally flatlands with grass</u>

The acceleration of Moby is 2 m/s²
<u>Explanation:</u>
Given:
Time, t = 5 seconds
Velocity, v = 10 m/s
Acceleration ,a = ?
We know:
On substituting the value we get:
Therefore, the acceleration of Moby is 2 m/s²
