1.) homogeneous mixtures
2.) <span>NaCI, because sodium is a metal and chlorine is a nonmetal</span>
3.) I'm thinking the first the option
The final temperature, t₂ = 30.9 °C
<h3>Further explanation</h3>
Given
24.0 kJ of heat = 24,000 J
Mass of calorimeter = 1.3 kg = 1300 g
Cs = 3.41 J/g°C
t₁= 25.5 °C
Required
The final temperature, t₂
Solution
Q = m.Cs.Δt
Q out (combustion of compound) = Q in (calorimeter)
24,000 = 1300 x 3.41 x (t₂-25.5)
t₂ = 30.9 °C
Answer: 11.25 J
Explanation: Kinetic energy is expressed as the product of mass and the squared of velocity divided by 2.
71% of the earth is water and the 29% is continents and islands.
Answer:
Phosphorus
Sulphur
And chlorine are non metals when bonded covalently gain electronic configuration of argon
Like PCl3
SO2 and HCl
