Answer:

Hey!

Your answer is that one block of metal (the cold one) would heat up a bit whilst the other block (the hot one) would cool down...This is because of the metal's CONDUCTIVITY!

Explanation:

Eventually you would measure the temperature of both blocks and they will reach the same temperature. After this they will naturally cool down...

HOPE THIS HELPS!!

Answer:

They will both cool down overtime

Explanation:

Once you put something that is hot on something that is cold. They will both be hot, but overtime they will cool down. It can't stay hot forever.

Helium decays to form lithium. Which equation correctly describes this decay?
GrogVix [38]

Answer:

⁴He₂ → ⁴Li₃ + ⁰e₋₁.

Explanation:

  • Helium decays with the release of an electron to form a lithium nucleus.
  • The number of nucleons is the same on both sides of the equation.
  • A neutron decays to form a proton with the release of an electron.
  • The atomic number increases from 2 to 3 while the atomic mass number stays the same at 4 nucleons.

Explain what makes a covalently bonded molecule polar. Use the molecules of CH4 and CH3F as examples in your explanation.
RideAnS [48]

Answer:

See explanation

Explanation:

The magnitude of electronegativity difference between atoms in a bond determines whether that bond will be polar or not.

If the electronegativity difference between atoms in a bond is about 1.7, the bond is ionic. If the electronegativity difference is greater than 0.4 and less than 1.7, the bond will have a polar covalent character. Lastly, if the electronegativity difference between the bond is less than or equal to 0.4, the covalent bond is non polar.

The electronegativity difference between carbon and hydrogen is about 0.4 which corresponds to a nonpolar covalent bond hence the molecule is nonpolar.

The electronegativity difference between carbon and fluorine is about 1.5 indicating a highly polar bond. This gives CH3F an overall dipole moment thereby making the molecule polar.

What is a promblem based on charles' law?
LUCKY_DIMON [66]

Answer:

You will never know the exact volume with charles law

Explanation:

Doubling the temperature of gas doubles its volume, so long as the pressure and quantity of the gas are unchanged.
