Answer: Electrons
Explanation:
Most of an atoms' mass comes from the protons and neutrons that make up its nucleus. Electrons have the least mass of an atom's particles.
Answer:
22m/s
Explanation:
Given parameters:
Time = 5s
Acceleration = 4m/s²
Initial velocity = 2m/s
Unknown
Final speed = ?
Solution:
To solve this problem, we use the expression below;
v = u + at
v is the final speed
u is the initial speed
a is the acceleration
t is the time taken
So, insert the parameters and solve;
v = 2 + 4 x 5 = 22m/s
A general formula of an acid always start with an hydronium ion or H+. The general formula of an acid have to end with an anion. As acids, these compounds are named starting with the prefix "hydro-," then adding the first syllable of the anion, then the suffix "-ic."
Answer: A 59.5 degree celcius
The equation that we will use to solve this problem is :
PV = nRT where:
P is the pressure of gas = 1.8 atm
V is the volume of gas = 18.2 liters
n is the number of moles of gas = 1.2 moles
R is the gas constant = 0.0821
T is the temperature required (calculated in kelvin)
Using these values to substitute in the equation, we find that:
(1.8)(18.2) = (1.2)(0.0821)(T)
T = 332.5 degree kelvin
The last step is to convert the degree kelvin into degree celcius:
T = 332.5 - 273 = 59.5 degree celcius
