A 800 kg car zooms away from a red light with an acceleration of 7.6 m/s2. What is the
aev [14]

Answer:

6080 N

Explanation:

From the question given above, the following data were obtained:

Mass (m) of car = 800 Kg

Acceleration (a) of car = 7.6 m/s²

Force (F) =?

The force experienced by the car can be obtained as illustrated below:

Force (F) = mass (m) × acceleration (a)

F = m × a

F = 800 × 7.6

F = 6080 N

Thus, the experience a force of 6080 N

The heat of vaporization for water is 40. 7 kJ/mol. How much heat energy must 150. 0 g of water absorb to boil away completely?
netineya [11]

The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.

The heat of vaporization has been the amount of heat required to vaporize 1 gram of liquid.

The heat required for the vaporization has been given as:

Q=m\Delta H_{vap}

<h3 /><h3>Computation for the Heat of vaporization</h3>

The heat of vaporization of water has been given as, \Delta H_{vap}=40.7\;\rm kJ/mol

The mass of water sample has been, m=150\;\rm g

Substituting the values for the heat energy absorbed, <em>Q:</em>

<em />

<em />Q=150\;\times\;40.7\;\rm kJ\\&#10;\textit Q=6,105\;kJ

The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.

Which is the Net Ionic Equation for:
arlik [135]

Answer: 2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and are present in an aqueous state and represented in the form of ions.

Net ionic equation : In the net ionic equations, we do not not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

 The complete balanced ionic equation will be:

2Fe^{3+}(aq)+6Cl^-(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+6Cl^-(aq)+2Fe(s)

 In this equation, Cl^- are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be:

2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)
