The heat in particles travels through convection at a certain speed depending on what density a mass has.
Acid is 1. a substance that increases the hydrogen ion concentration of a solution
<span>2. removes hydroxide ions because of the tendency for H+ to combine with OH-</span>
Answer: 0.9375 g
Explanation:
To calculate the number of moles for given molarity, we use the equation:
.....(1)
Molarity of
solution = 0.75 M
Volume of
solution = 25.0 mL = 0.025 L
Putting values in equation 1, we get:
According to stoichiometry :
2 moles of
require = 1 mole of
Thus 0.01875 moles of
will require=
of
Mass of
Thus 0.9375 g of
is required to react with 25.0 ml of 0.75 M HCl
Answer:
The volume will be occupied is 244, 36L.
Explanation:
We convert the unit of temperature to celsius into Kelvin, then use the ideal gas formula, solve for V (volume) and use the gas constant R =0.082 l atm / K mol:
0°C=273K 25°C= 273 + 25=298K
PV=nRT ---> V=nRT/P
V= 5,00 mol x 0,082 l atm/ K mol x 298 K/0,500 atm
<em>V=244,36L</em>
Answer: heck the chemistry app itll help you i dont know this answer but the app will tell u!
