Answer:

2HNO3+Ca(OH)2 ---> Ca(NO3)2+2H2O

you put the two on the H2O to make it 2H2O and A two on the HNO3 to make it 2HN03 To make it balanced

Reactants:

2HNO3 has 2 H atoms, 2 N atom and 6 O atoms

Ca(OH)2 has 1 Ca atom, 2 O atoms and 2 H atoms

Left side: 4 H atoms, 2 N atoms, 8 O atoms, 1 Ca atom

Products:

Ca(NO3)2 has 1 Ca atom, 2 N atoms, 6 O atoms

2H2O has 4 H atoms (2 x 2), and 2 O atoms

Right side: 1 Ca atom 2 N atoms, 8 O atoms, 4 H atoms

The average rate of disappearance of ozone in the reaction 2o3(g) → 3o2(g) is found to be 7.25×10–3 atm over a certain interval
worty [1.4K]
<h3><u>Answer</u>;</h3>

1.0875 x 10-2 atm

<h3><u>Explanation;</u></h3>

2O3(g) → 3O2(g)

rate = -(1/2)∆[O3]/∆t = +(1/3)∆[O2)/∆t  

The average rate of disappearance of ozone ... is found to  

be 7.25 × 10–3 atm over a certain interval of time.

This means (ignoring time)

∆[O3]/∆t = -7.25 × 10^–3 atm  

(it is disappearing, thus the negative sign)

rate = -(1/2)∆[O3]/∆t  

rate = -(1/2)*(-7.25 × 10^–3 atm)

      = 3.625 × 10^–3 atm  

Now use the other part of the expression:  

rate = +(1/3)∆[O2)∆t  

3.625 × 10–3 atm = +(1/3)∆[O2)/t  

∆[O2)/∆t = (3)*(3.625× 10^–3 atm)

              = 1.0875 x 10-2 atm over the same time interval

What affects the direction of the current moving through a wire? Check all that apply
NISA [10]

Answer : Option A) The direction the wire moves in


and Option C) the direction of the magnetic field.


Explanation : The direction of current flowing through the wire mainly depens on two factors which are i) direction of the wire moves in and ii) the direction of magnetic field.


The flow of current will occur in the direction of the wire through which it is moving in, whereas the direction of magnetic field will be in concentric circles around the direction of current passing through the wire.
