If a 50.0 g piece of glass is heated from 20.0°C to 40.0°C, how many joules of heat are added? The specific heat of glass is 0.5
Andrews [41]

Answer:

500J (joules)

Explanation:

since heat is is the product of mass, change in temperature, and specific heat, the solution can be found from the equation q = mcΔt, heat is 50 * .5 * 20 = 500J

What do you expect will occur as air masses move over cold locations? Hot locations? How does this movement of air masses affect
Maksim231197 [3]

Answer:

Explanation:

When air masses will move over cold location then bottom layer of air cools and become more dense. Due to its high density it is trapped near the ground then it flow towards the equator.

When it moves over hot location then bottom layer gets hot and lighter. Then it moves towards poles.

It changes the temperature and humidity of the climate. making hoter region coll and cooler region a bit hot.

Neutralization of Gastric Acid. In the duodenum, gastric acid is neutralized by sodium bicarbonate (pH of about 8.5)
The pH of sodium citrate solutions typically exceeds 7.0, and common antacid, calcium carbonate, is 9.91.
Considering bleach has a pH of about 13 that’s definitely the wrong answer.
7 sounds the most reasonable but 6.5 is not far off.

What are the respective concentrations (moles/liter) of k+ and po43- afforded by dissolving 0.800 mol k3po4 in water and dilutin
Kitty [74]

<em>Answer: </em>

  •                      Concentration of K+  = 1.47 M
  •                      Concentration of Po4∧-2 = 0.4908 M

<em>Given Data:</em>

   No. of moles of K3PO4 = 0.800 mole

  Molarity of K3PO4 =  0.800÷1.63 = 0.4908

<em>Chemical equations:</em>

        K3PO4 ⇔3 K+   +  PO4∧-2

<em>Solution: </em>

         K3PO4 : K+                                                K3PO4 : PO4∧-2

            1  :    3                                                            1      :    1

        0.4908 = 0.4908 × 3 = 1.47 M                   0.4908 = 0.4908 × 1 = 0.4908 M
