We know that density of olive oil = 0.93 g/mL
Given that mass of olive oil = 1.4 kg or 1400 g because 1000 g = 1.0 kg
From the definition of density;
Volume = mass/ density
= 1400 g/ 0.93 g/mL
=1505 mL
Answer:
The correct answer is 7,812.5J
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
Answer:
Convection
Explanation:
▶ Convection is the transfer of heat through a gas or a liquid. The gas in this case would be the air passing through the heat and moving in a large quantity that then heats the hair.
<em>It may be all of the above since the hair dryer is using both convection and conduction produce hot air but it says </em><em>clearly</em><em> so im assuming its Convection.</em>
