Answer:

When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe - even at a trickle - helps prevent pipes from freezing.

Remember to keep both cold and hot water dripping during these frigid temperatures. We know to keep the faucets dripping when temperatures dip below freezing, but experts say you need to keep both cold and hot water open

Hope this helps :) pls give brainliest

How the metals react with oxygen? Give the general formula and explain the reaction of sodium with oxygen with chemical equation

slamgirl [31]

Answer:

Sodium is a very reactive metal, it tends to react with oxygen to form sodium oxide but this is an unstable compound and soon reacts with hydrogen to form sodium hydroxide. Sodium is the metal reacts vigorously with oxygen and water.

4 Na + O2 → 2 Na2O.

Answer:

Charles's law states that V1 / T1 = V2 / T2. However, you must make sure that T is in Kelvin, not C.

1.19E6 / (11 + 273) = V2 / (113 + 273)

V2 = 1.62E6

Explanation:

Gases expand when heated if the container they are in is flexible. When the gas is heated its molecules move faster and faster. The collisions of the gas particles with the flexible container wall expand.

If you keep heating a liquid, what happens to the energy of the particles in the liquid?

larisa86 [58]

Answer:

theres gonna be more energy and some of the particles with a lot of energy will become vapor and evaporate

Explanation:

"If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapor as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away."

alexandr402 [8]

Answer:

c. I, Br, Cl

Explanation:

The option C group of elements is expected to have the highest ionization energy.

Ionization energy is the energy needed to remove the most loosely held electron from an atom.

As such, ionization energy increases from left to right on the periodic table.
It reduces from top to bottom
The groups to the right will not readily lose their electrons.
Therefore, I, Br and Cl being in group 7 will have the highest ionization energy.
