An element that is malleable is _____. difficult to pour easily shaped very hard very dense

Chemistry
1 answer:
noname [10]3 years ago
6 0
The answer is easily shaped. Malleable means it can be shaped with ease without breaking them.
This is a common property in metals. For example, aluminum, they can be shaped into thin aluminum foil sheets because they're malleable.
In the other hand, for many non metals and semi metals, they're brittle, the opposite of malleable. They tend to break easily.

The compound whose molecules have the highest average kinetic energy is?
KIM [24]

Answer:

C)

Explanation:

The warmer the molecules, the higher the average kinetic energy.

"As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles. This is registered as an increase in the temperature of the substance." -lumen learning

What was the major weakness of Wegener's theory of continental drift
Alik [6]

Alfred Wegener proposed the continental drift theory  in four reasons. One, he hypothesized that the continents were once a giant continent. Two, he observed that there are fossils found of the same kind in the different locations. Three, he found that the edge of opposing continents somehow fits if they are combined, almost like a puzzle. And four, there are glacial scars that are left behind by a larger glacial continent. His greatest weakness of Alfred Wegeners’ continental drift theory was he could not explain what kind of force that caused this continents to move far from each other.

How many moles of tungsten carbide will be produced if plenty of tungsten is reacted with 1.25 moles of carbon?
Tanya [424]

Answer:

1.25 moles of tungsten carbide

Explanation:

Tungsten carbide, WC, is a substance that is produced prom carbon and tungsten as follows:

W + C → WC

Based on the reaction, 1 mole of Carbon produce 1 mole of tungsten carbide. That means if 1.25 moles of carbon are added in excess of tungsten, the moles of tungsten carbide produced are:

What will happen to the temperature, as<br> thermal energy is added to the ice over time?<br> OK
satela [25.4K]

Answer:

When you heat ice, its temperature rises, but as soon as the ice starts to melt, the temperature stays constant until all the ice has melted. This happens because all the heat energy goes into breaking the bonds of the ice's crystal lattice structure.

Explanation:

Shards of ice fly from the sculptor’s chisel. As the crowd

looks on, a swan slowly emerges from a massive block of ice. As

the day wears on, however, drops of water begin to fall from the

sculpture. Drip by drip, the sculpture is transformed into a puddle of liquid water. What makes matter change from one state to

another? To answer this question, you need to think about the

particles that make up matter.

Energy Simply stated, energy is the ability to do work or cause

change. The energy of motion is called kinetic energy. Particles

within matter are in constant motion. The amount of motion of

these particles depends on the kinetic energy they possess. Particles

with more kinetic energy move faster and farther apart. Particles

with less energy move more slowly and stay closer together.

The total kinetic energy of all the particles in a sample of

matter is called thermal energy. Thermal energy, an extensive

property, depends on the number of particles in a substance as

well as the amount of energy each particle has. If either the

number of particles or the amount of energy in each particle

changes, the thermal energy of the sample changes. With identically sized samples, the warmer substance has the greater thermal energy. In Figure 7, the particles of hot water from the hot

spring have more thermal energy than the particles of snow on

the surrounding ground.
