Answer:
d) 0.055 km east
Explanation:
Displacement is defined as the difference between the start point to the end point.
Assuming that we started from point zero, the displacement will be the same as the distance traveled.
The rule that relates velocity, time and distance is:
velocity = distance / time
we are given that:
velocity = 0.11 km/hr
time = 30 minutes = 0.5 hour
Substitute with the givens in the above equation to get the distance as follows:
0.11 = distance / 0.5
distance = 0.11*0.5 = 0.055 km
As for the direction, we are given that it is eastwards

Hope this helps :)

All elements have a AHf, of ___
stellarik [79]

All elements have a AHf, of <u>0</u>

kJ/mole at standard temperature and pressure.

<h3>What is an element?</h3>

An element can be defined as a substance which cannot be split into two or more simpler forms by an ordinary chemical process

Below are the list of the first twenty elements:

  • Hydrogen
  • Helium
  • Lithium
  • Berylium
  • Boron
  • Carbon
  • Nitrogen
  • Oxygen
  • Fluorine
  • Neon
  • Sodium
  • Magnesium
  • Aluminum
  • Silicon
  • Phosphorus
  • Sulphur
  • Chlorine
  • Argon
  • Potassium
  • Calcium

So therefore, all elements have a AHf, of <u>0</u>

kJ/mole at standard temperature and pressure.

How many Liters of 0.50M HCl are needed to neutralize 0.050L of 0.101M Ba(OH)2?
Aleksandr-060686 [28]

Answer:

V_{HCl}=5.05x10^{-3}L

Explanation:

Hello,

In this case, since hydrochloric acid and barium hydroxide are in a 2:1 molar ratio, for the neutralization, the following moles equality must be obeyed:

2*n_{HCl}=n_{Ba(OH)_2}

In such a way, in terms of molarities and volumes, we can compute the required volume of hydrochloric acid as shown below:

2*M_{HCl}V_{HCl}=M_{Ba(OH)_2}V_{Ba(OH)_2}\\\\V_{HCl}=\frac{M_{Ba(OH)_2}V_{Ba(OH)_2}}{2M_{HCl}} =\frac{0.101M*0.050L}{2*0.50M} \\\\V_{HCl}=5.05x10^{-3}L

Besr regards.
