A flight simulator that helps astronauts prepare for a shuttle launch is an example of a Scientific Model.
Answer:
m = 31.284 grams
Explanation:
Given that,
The dimension of a magnesium block is 2.00 cm x 3.00 cm x 3.00 cm.
The density of magnesium is, d = 1.738 g/cm³
We need to find the mass of the magnesium block. We know that the density of an object is given by its mass per unit its volume. So,
So, the mass of the block is 31.284 grams.
Answer: 15062.4 Joules
Explanation:
The quantity of heat energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = ?
Mass of food = 200.0g
C = 4.184 j/g°C
Φ = (Final temperature - Initial temperature)
= 83.0°C - 65.0°C = 18°C
Then, Q = MCΦ
Q = 200.0g x 4.184 j/g°C x 18°C
Q = 15062.4 J
Thus, 15062.4 joules of heat energy was contained in the food.
A compound accepts electrons from another substance to form a covalent bond. The compound acts as a Lewis base.
<h3>What are the most common acid-base theories?</h3>
- Arrhenius: acids release H⁺ and bases release OH⁻.
- Bronsted-Lowry: acids donate H⁺ and bases accept H⁺.
- Lewis: acids accept electrons and bases donate electrons.
A compound accepts electrons from another substance to form a covalent bond. Which term best describes this compound’s behavior?
- Lewis acid. YES.
- Arrhenius base. NO, because OH⁻ is not involved.
- Bronsted-Lowry acid. NO, because H⁺ is not involved.
- Bronsted-Lowry base. NO, because H⁺ is not involved.
