According to Newtons second law of motion:
This shows, acceleration and mass are inversely proportional. So, larger the mass, less will be the acceleration produced and vice versa.
In case of a sports car and a fully loaded truck, the mass of truck is a lot more than the sports car. As a result the sports car will accelerate faster when the traffic light turns green.
Answer:
n = 0.651 mol
Explanation:
Given data:
Volume of CO₂ = 14.6 L
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Number of moles of CO₂ = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
by putting values,
1 atm × 14.6 L = n × 0.0821 atm.L/ mol.K × 273.15 K
14.6 L. atm = n × 22.43atm.L/ mol
n = 0.651 mol
Answer:
4
Explanation:
Light refracts when it passes through something transparent at an angle so that eliminates the other 3.
or put differently
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density)
It's called ”wire gauze”, a metal mesh used with a ring clamp to support glassware over a Bunsen burner. Spreads flame out for more even heating rates.
The answer to your question is option b, a base. This is because the question clearly tells you that one reactant is an acid. Then, it tells you that an acid plus something gives you a salt and water, as products
From background knowledge, we know that a base plus acid gives you a salt and water. The hydroxide ions from the base neutralise the hydrogen ions from the acid, which gives you water ( as it has a pH of 7).
Therefore, your answer is b, a base
