a cadillac escalade has a mass of 2.569 kg if it acceleratesat 4.65m/s what is the net force on the car

There are 2 moles of aluminum metal that is needed to produce 3.33 moles of aluminum chloride

Answer:

1279 °C

Explanation:

Data Given:

Amount of Heat absorb = 5.82 x 10³ KJ

Convert KJ to J

1 KJ = 1000 J

5.82 x 10³ KJ = 5.82 x 10³ x 1000 = 5.82 x10⁶ J

mass of sample = 8.92 Kg

Convert Kg to g

1 kg = 1000 g

8.92 Kg = 8.92 x 1000 = 8920 g

Cs of steel = 0.51 J/g °C

change in temperature = ?

Solution:

Formula used

             Q = Cs.m.ΔT

rearrange the above equation to calculate the mass of steel sample

             ΔT =  Q / Cs.m  .... . . . . . (1)

Where:

Q = amount of heat

Cs = specific heat of steel = 0.51 J/g °C

m = mass

ΔT = Change in temperature

Put values in above equation 1

                ΔT = 5.82 x10⁶ J / 0.51  (J/g °C) x 8920 g

                ΔT = 5.82 x10⁶ J /4549.2 (J/°C)

                ΔT = 1279 °C            

So,

change in temperature = 1279 °C

Answer:

The amount of sugar that can dissolve in water increase .

Explanation:

• Energy, which is the capacity to do work or produce heat, affects the rate at which a solute will dissolve.
• Breaking up, crushing or grinding a sugar cube before adding it to water increases the sugar's surface area.
• The more surface area a solute has, the faster it will dissolve because more particles of the sugar can interact with the water.
• This means the finer the sugar particles, the faster it will dissolve.
• The sugar in the middle of a sugar cube is protected from the water by the sugar in the outer layers of the cube; the water has to go through those outer layers first.
• But if you crush the cube into a powder, all of the sugar is exposed to the water at once.
