Answer:
Copper is typically a solid and has a coppery, bronzy color. It is a metal and has a relatively high melting point. It has a strong luster and can conduct electricity.
Answer:
A neutralized solution in chemistry refers to the reaction between an acid and base that results in a neutral balance, or a measure of 7 on the pH scale.
Explanation:
When 3.66 g of KOH (∆Hsol = -57.6 kJ/mol) is dissolved in 150.0 mL of solution, it causes a temperature change of 5.87 °C.
The enthalpy of solution of KOH is -57.6 kJ/mol. We can calculate the heat released by the solution (Qr) of 3.66 g of KOH considering that the molar mass of KOH is 56.11 g/mol.

According to the law of conservation of energy, the sum of the heat released by the solution of KOH (Qr) and the heat absorbed by the solution (Qa) is zero.

150.0 mL of solution with a density of 1.02 g/mL were prepared. The mass (m) of the solution is:

Given the specific heat capacity of the solution (c) is 4.184 J/g・°C, we can calculate the change in the temperature (ΔT) of the solution using the following expression.

Galileo disproved the Ptolemaic theory, sanctioned for centuries by the Church, which held the Earth to be the central and principal object in the universe, about which all celestial objects orbited.
Answer:
Mass = 19.78 g
Explanation:
Given data:
Mass of NO produced = ?
Mass of NO₂ reacted = 60.0 g
Solution:
Chemical equation:
3NO₂(g) + H₂O(l) → 2HNO₃(g) + NO(g)
Number of moles of NO₂:
Number of moles = mass/molar mass
Number of moles = 60.0 g/ 46 g/mol
Number of moles = 1.3 mol
Now we will compare the moles of NO₂ with NO.
NO₂ : NO
3 : 1
1.3 : 1/3×1.3 = 0.43 mol
Mass of NO:
Mass = number of moles × molar mass
Mass = 0.43 mol × 46 g/mol
Mass = 19.78 g
