Explanation:
speed = distance/time
= 23.7/54 m/s
= 0.44 m/s
speed of a dog running through a field = 0.44 m/s
We will assume that the only reactants are x and y and that the only product is xy.
Based on the law of mass conservation, mass is an isolated system that can neither be created nor destroyed.
Applying this concept to the chemical reaction, we will find that the total mass of the reactants must be equal to the total mass of the products,
therefore:
mass of x + mass of y = mass of xy
12.2 + mass of y = 78.9
mass of y = 78.9 - 12.2 = 66.7 grams
The steam rotates a turbine that activates a generator, which produces electricity. Many power plants still use fossil fuels to boil water for steam. Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface.
Answer:
Gay-Lussac's law states that in a closed system of fixed volume, as the temp and the pressure of the gas increases.
Explanation:
Temperature is a measure of the average kinetic energy of a substance. As the temp of a substance rises, its molecules are moving faster
Answer:
Explanation:
Ba(OH)₂ + 2HCl ⟶ BaCl₂ + H₂O
V/mL: 249
c/mol·L⁻¹: 0.0443 0.285
1. Calculate the moles of Ba(OH)₂
2. Calculate the moles of HCl
The molar ratio is 2 mol HCl:1 mol Ba(OH)₂
3. Calculate the volume of HCl
