Answer:A-lift

Explanation:The shape of an airfoil causes air to flow faster on top than on the bottom.A fast flowing air decreases the sounding air pressure, because the air pressure is greater below the airfoil than above, resulting to lift force.

Solve the equation for x.4+2(x-4)=-7(x+7)

OverLord2011 [107]

Answer:

$x=-5$

Explanation:

we have

$4+2(x-4)=-7(x+7)$

Solve for x

That means----> Isolate the variable x

Applying the distributive property both sides

$4+2(x)+2(-4)=-7(x)-7(7)$

Remember that

$(+1)(-1)=-1$

$4+2x-8=-7x-49$

Combine like terms left side

$2x-4=-7x-49$

Adds 7x both sides

$2x-4+7x=-7x-49+7x$

$9x-4=-49$

Adds 4 both sides

$9x-4+4=-49+4$

$9x=-45$

Divide by 9 both sides

$x=-5$

Balance each reaction and write its reaction quotient, Qc:(a) NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

AleksAgata [21]

When we balance the given equation

NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We will get

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

Solution:

Balancing the given equation

NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We have to balance the number of Cl

2NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We have to balance the number of N, O.

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

We will get the balanced equation

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

The reaction quotient will be

Qc = [product] / [reactant]

Qc = [NO₂(g) + Cl₂(g)] / [NO₂Cl(g)]
