Explanation:

aluminum can be used to make soft drink cans because of which property?
A. It can be hammered into a thin sheet (malleability)
B.it can reflect light (shininess)
C.It can be drawn into long wires(ductility)

Answers

Answer:

A

Explanation:

Malleability describes the property of a metal's ability to be distorted below compression. It is a physical property of metals by which they can be hammered, shaped and rolled into a very thin sheet without rupturing. A soda can's walls are very thin, and therefore express the malleability of aluminum.

How many significant digits are found?

Answers

Answer:

4

Explanation:

There are 4 significant figures because when there is not a decimal, then only numerical values over 0 are counted. So the numbers counted in sig figs are 2049, and none of the other 0s.

So if it was 204,900,000,000.0, then it would have 12 significant figures.

How do animals and plants rely on each other in the prairie? ITS TIMED

There are many decomposers in the prairie that can be used as food sources for first-order consumers.
There is more sunlight in the prairie for plants to grow, and therefore more food sources for animals.
Second-order consumers eat the grass as their food source.
The grass in the prairie provides oxygen, while animals give off carbon dioxide gas.

Answers

Answer:

I would assume its the last one "The grass in the prairie provides oxygen, while animals give off carbon dioxide gas."

Explanation:

The question asks how the animals and plants rely on each other

The plants provide oxygen and food for the animals, and the animals provide carbon dioxide to them.

negative ions form when atoms _______ valence electrons.

Answers

Answer:

Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,

Explanation:

so it becomes negatively charged.

Negative ions (or anions) are atoms that have gained electrons.

Electrons have a negative charge so if an atom is getting more of them, it's becoming more negative.

Use the following image to answer the following questions. A student was performing an experiment using two identical cups made of styrofoam.

A student wants to calculate the heat gained of 100 grams of water in order to
calculate the specific heat of a metal in the following problem. The water is
heated from 25C to 50C when the metal is added. The specific heat of water is
4.18 J/gºC. Use Q=m xCxT*

Answers

The quantity of heat gained to raise the temperature from 25.0°C to 50.0°C is 10,450 Joules.

Given the following data:

Mass of water = 100 gramsInitial temperature = 25.0°CFinal temperature of water = 50.0°CSpecific heat capacity of water = 4.18 J/g°C

To find the quantity of heat gained:

Mathematically, heat capacity or quantity of heat is given by the formula;

[tex]Q = mc\theta[/tex]

Where:

Q represents the heat capacity or quantity of heat.m represents the mass of an object.c represents the specific heat capacity.∅ represents the change in temperature.

Substituting the values into the formula, we have:

[tex]Q = 100(4.18)(50 - 25)\\\\Q = 418(25)[/tex]

Quantity of heat = 10,450 Joules.
