6. What is the mass of the object if the net force acting on it was 356 N and the acceleration rate
Marina86 [1]

The mass of an object with a net force of 356N and an acceleration rate of 4m/s² is 89kg.

<h3>How to calculate mass?</h3>

The mass of an object can be calculated using the following formula:

F = ma

Where;

  • F = force (N)
  • m = mass (kg)
  • a = acceleration (m/s²)

m = F/a

m = 356/4

m = 89kg

Therefore, the mass of an object with a net force of 356N and an acceleration rate of 4m/s² is 89kg.

What is the net ionic equation of the reaction of MgSO4 with Pb(NO3)2?
NemiM [27]

Hey there!:

Write the molecular equation for the reaction of MgSO4 with Pb(NO3)2 :

MgSO4(aq) + Pb(NO3)2(aq) ---> Mg(NO3)2(aq) + PbSO4(s)

Write the total ionic equation  for the reaction :

Mg²⁺ (aq) + SO₄⁻² (aq) + Pb²⁺ (aq) + 2 NO₃⁻¹ (aq) + PbSO₄(s)

Therefore:

Cancel the spectator ions on both sides:

Pb²⁺ (aq) + SO₄⁻² (aq) ---> PbSO4(s)


Hope that helps!
