Answer:
A. ionizing energy increases
Answer:
Box is made up of <em>copper</em>, because density is <em>8.96 g/cm³.</em>
Explanation:
Given data:
Volume of box = 17.63 cm³
Mass of box = 158 g
Which metal box is this = ?
Solution:
First we will calculate the density of box then we will compare it with the density value of given metals.
d = m/v
d = 158 g/ 17.63 cm³
d = 8.96 g/cm³
The calculated density is similar to the given density value of copper thus box is made up of copper.

whats the question?????????????
Answer:
0.501 M
Explanation:
First we <u>convert 1.513 g of KHP into moles</u>, using its <em>molar mass</em>:
- 1.513 g ÷ 204.22 g/mol = 7.41x10⁻³ mol = 7.41 mmol
As <em>1 mol of KHP reacts with 1 mol of NaOH</em>, in 14.8 mL of the NaOH solution there were 7.41 mmoles of NaOH.
With the above information in mind we can <u>calculate the molarity of the NaOH solution</u>:
- 7.41 mmol / 14.8 mL = 0.501 M
Answer:
C. The tea cools to room temperature, the ice cream melts and warms to room temperature.
Explanation:
The tea's temperature was higher than room temperature. The ice cream's temperature was lower than room temperature. After some time, both items will become room temperature, which results in cooling and melting.
