The statement above is TRUE.
When heat is added to a substance, the heat increases the kinetic energy of the particles of the substance and enable to vibrate or move faster, this usually increase the temperature of the substance. However, adding heat does not always increase the temperature of a substance. For instance, during the process of boiling point of water, the additional heat energy that is added to the water is used to break the chemical bonds in water and not to increase the temperature of water.<span />
Answer:
Na3PO4 + 3KOH -------> 3NaOH + K3PO4
Explanation:
Answer:
The pressure will be halved with respect its initial value
Explanation:
Based on Boyle's law, <em>the pressure exerted by a quantity of an ideal gas is inversely proportional to the volume it occupies if the temperature and remains constant</em>
<em />
Thus, if volume of a gas is doubled while the temperature is unchanged, <em>the pressure will be halved with respect its initial value</em>
Answer: 0.33M CaBr2
Explanation: Molarity is expressed in moles of solute over liter solution.
M= n solute / L solution
Solution:
First convert mass of CaBr2 to moles using its molar mass
Ca = 40
Br = 80 x 2 answer is 200 g CaBr2.
50.0g CaBr2 x 1 mole CaBr2 / 200 g CaBr2 = 0.25 moles CaBr2
Next convert mL to L
750.0 mL x 1L / 1000mL
= 0.75 L
Substitute the values for M.
M= 0.25 moles CaBr2/ 0.75 L
= 0.33 M CaBr2
