Diamond consists of carbon atoms tetrahedrally arranged and bonded by strong covalent bonds. Graphite consists of carbon atoms arranged in hexagonal rings and in layers. Each carbon atom is bonded to three other atoms arranged hexagonally in layers.
Answer:
0.315 atm
Explanation:
PV = nRT
P(96.2) = (1.24)(0.08206)(25 + 273)
P = 0.315 atm
Answer:
b
Explanation fission reaction the mass defect is negative
Potassium can be a component of the cream.
<h3>Why does potassium show white-purple flame when burned?</h3>
An element's presence can be determined using a flame test. The potassium in cream of tartar is what gives it its white-purple color.
Low ionization enthalpy elements allow the flame to display color. Due to low ionization enthalpy, when an element is heated, its valence electrons are quickly excited to higher orbits and emit light as they return to their original orbit. Salts of potassium emit a white-purple color when ignited. The cream of tartar's chemical formula is KC₄H₅O₆.

Answer:
805.3cal
Explanation:
All neutralization reactions produce heat when occurs.
The reaction of HCl with NaOH produce heat increasing the aqueous medium in 5.43°C. The equation of the released energy is:
Q = S×m×ΔT
<em>Where Q is heat, </em>
<em>S is specific heat of the solution (1.00cal/g°C)</em>
<em>m is mass of water: 148.3g</em>
<em>ΔT is change in temperature: 5.43°C</em>
<em />
Q = 1.00cal/g°C×148.3g×5.43°C
Q = 805.3cal
