Darina [25.2K]3 years ago
7 0
The correct answer is:
a positron is emitted when proton converts to a neutron.

The reaction can be described as following:
₁¹p (proton) → ₀¹n (neutron) + ₁°e (positron or ₁⁰β)
Positron is an antiparticle of a β particle (₋₁°β), which means it has an oposite charge to it, but same mass.

Q = m.c.AT

m = 50,0 g of iron

c = 0.450 J.g-1°C-1

AT = 10°C

Thus

Q = 50 * 0.450 * 10

Q = 225 J

Is the heat energy

Answer: 18g

Explanation:

1 mle of glucose combusts to give 6moles of CO2 and 6moles of H2O

C6H12O6 + 6O2-------- 6CO2 + 6H2O at STP.

Multiplying 6 by 3 moles we have 18 g of CO2

Which forces involve nonpolar molecules?
Elanso [62]
The answer is London dispersin forces and dipole-induced dipole forces.

The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction. This force is found in any compound and is the weakest atraction force between atoms or molecules.

Those temporay dipoles are not like the dipoles that form the polar molecules, because the polar molecules are the result of permanent dipoles.
