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

Chemistry
1 answer:
OverLord2011 [107]3 years ago
4 0

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

Answer:

Increases

Explanation:

As ice melts into liquid water, the kinetic energy of the particles increases.

This is because to melt ices, heat energy is supplied.

  • The sum total of all the average speed of the particles in a substance is the heat energy.
  • Heat is a form of kinetic energy.
  • As more heat is added, the particles moves rapidly and the kinetic energy increase.

A gas cylinder contains 2.5 atm of ne, 0.8 atm of co2, and 3.4 atm of ar. what is the total pressure in the cylinder? g
Tatiana [17]
To answer this problem, we must make assumptions for simplicity. The first assumption is that, the system only consist of these 3 gases. The second assumption is that, these gases behave ideally. Thus, from Dalton's Law of Partial Pressure, the total pressure is simply the sum of their individual partial pressures.

Total pressure = 2.5 + 0.8 + 3.4 = <em>6.7 atm</em>

When a kettle is placed on the stove and water begins to boil, the hotter water at the bottom begins to rise and the
My name is Ann [436]

Answer:

The cooler water is denser

Explanation:

Convection drives the boiling of water placed on a stove in a kettle.

During convection, heat is circulated by density differences in portions of a fluid.

Convection is a form of heat transfer in fluids especially gas and liquid.

  • In boiling water, the heat is supplied to the base of the stove.
  • The water at the bottom on heat becomes lighter as the molecules gain more kinetic energy.
  • The colder part of the water on top sinks to replace the less dense on below.
  • This exchange sets up convection cells in the kettle.
