Answer: 11.18atm
Explanation:Please see attachment for explanation
The rock cycle is the process of converting rock between igneous, sedimentary, and metamorphic forms. ... Molten rock inside the Earth undergoes a phase change as it cools to produce solid igneous rock. The chemical changes which form the rock depend on the type of minerals present and how fast the rock cools.
Answer:
The volume of first and second compound are 9.15 ml and 10.85 ml.
Explanation:
Given that,
Density of graphite = 2.25 g/cm³
Volume of mixture = 20.0 mL
Density of first compound = 1.492 g/ml
Density of second compound = 2.890 g/ml
Let the volume of first mixture = x
The volume of second mixture = (20-x)....(I)
We need to calculate the volume of first compound
Using formula of density of mixture
Where, 
= volume of first compound
= volume of second compound
=density of first compound
= density of first compound
Put the volume into the formula
We need to calculate the volume of second compound
Using equation (I)
Put the value of x
Hence, The volume of first and second compound are 9.15 ml and 10.85 ml.
Answer:
-2
Explanation:
Consider object is starting 12 units right from the reference point which is 0.
Assign the right direction positive sign.
when object is moving 14 units on left direction the position of object will be two units to the left side of reference point.
Assign the left direction negative sign position will be -2.
Answer:
Option D is correct = 58 g
Explanation:
Data Given:
mass of LiOH = 120 g
Mass of Li3N= ?
Solution:
To solve this problem we have to look at the reaction
Reaction:
Li₃N (s) + 3H₂0 (l) -----------► NH₃ (g) + 3LiOH (l)
1 mol 3 mol
Convert moles to mass
Molar mass of LiOH = 24 g/mol
Molar mass of Li₃N = 35 g/mol
So,
Li₃N (s) + 3H₂0 (l) -----------► NH₃ (g) + 3LiOH (l)
1 mol (35 g/mol) 3 mol (24 g/mol)
35 g 72 g
So if we look at the reaction 35 g of Li₃N react with water and produces 72 g of LiOH , then how many g of Li₃N will be react to Produce by 120 g of LiOH
For this apply unity formula
35 g of Li₃N ≅ 72 g of LiOH
X of Li₃N ≅ 120 g of LiOH
By Doing cross multiplication
Mass of Li₃N = 35 g x 120 g / 72 g
mass of Li₃N = 58 g
120 g of LiOH will produce from 58 g of Li₃N
So,
Option D is correct = 58 g
