If you wanted to take a solid nugget of silver and make it flow so that it can be shaped, how could you do it? you could...

Answers

Answer 1

Answer:

It should be heated

Explanation:

To change the solid nugget of silver to liquid so that it can be shaped, the solid mass should be heated to the melting point.

This change is a phase change from solid to liquidWhen the melting point of a substance is reached, the fixed lattice structure collapses. This allows for the particles to slide and flow relative to one another.

Therefore a phase change from solid to liquid is attained by heating of the solid to melting point.

Which force helps food move through the large intestine during digestion?

A Muscle contractions exert a pushing force on the food.
B Oxygen molecules exert a pulling force on the food.
C Gravity exerts an upward pushing force on the food.
D Water exerts an upward pushing force on the food.

Answers

Answer:

The answer is A

Explanation:

Pls put me as brainliest

The force helps food move through the large intestine during digestion is muscle contractions exert a pushing force on the food. Thus option A is correct.

What is force?

Force is defined as a push or pull upon any object resulting from the object's interaction with another object. It is a vector quantity.

Force can also be defined as an external cause that, when applied, changes or tends to change the state of the body, if the body is in motion.

Force is expressed as

Force = mass x acceleration

There are five types of force

Gravitational forceElectric forceMagnetic forceNuclear forceFrictional force

Digestion is define as the breakdown of food into smaller component  that can be absorbed into blood streams.

Thus, the force helps food move through the large intestine during digestion is muscle contractions exert a pushing force on the food. Thus option A is correct.

You dissolve 8.65 grams of lead(II) nitrate in water, and then you add 2.50 grams of aluminum. This reaction occurs: 2Al(s) + 3Pb(NO3)2(aq) → 3Pb(s) + 2Al(NO3)3(aq). What’s the theoretical yield of solid lead? Use the ideal gas resource and the periodic table. A. 5.41 g B. 11.2 g C. 19.2 g D. 28.8 g Reset

Answers

Answer: A. 5.41

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} Al=\frac{2.50g}{27g/mol}=0.0926moles[/tex]

[tex]\text{Moles of} Pb(NO_3)_2=\frac{8.65g}{331g/mol}=0.0261moles[/tex]

[tex]2Al(s)+3Pb(NO_3)_2(aq)\rightarrow 3Pb(s)+2Al(NO_3)_3(aq)[/tex]  

According to stoichiometry :

3 moles of [tex]Pb(NO_3)_2[/tex] require  = 2 moles of [tex]Al[/tex]  

Thus 0.0261 moles of [tex]Pb(NO_3)_2[/tex] will require=[tex]\frac{2}{3}\times 0.0261=0.0174moles[/tex]  of [tex]Al[/tex]

Thus [tex]Pb(NO_3)_2[/tex] is the limiting reagent as it limits the formation of product and [tex]Al[/tex] is the excess reagent.

As 3 moles of [tex]Pb(NO_3)_2[/tex] give = 3 moles of [tex]Pb[/tex]

Thus 0.0261 moles of [tex]Pb(NO_3)_2[/tex] give =[tex]\frac{3}{3}\times 0.0261=0.0261 moles[/tex]  of [tex]Pb[/tex]

Mass of [tex]Pb=moles\times {\text {Molar mass}}=0.0261moles\times 207g/mol=5.41g[/tex]

Thus 5.41 g of solid lead will be produced from the given masses of both reactants.

Calculate the concentration of hydrogen ion of a sample of vinegar with pH 6.82

Answers

The concentration of hydrogen ion of a sample of vinegar : 1.514 x 10⁻⁷

Further explanation

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.

A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.

pH = - log [H⁺]

pH of a sample vinegar = 6.82

The concentration of hydrogen ion :

[tex]\tt 6.82=-log[H^+]\\\\(H^+]=10^{-6.82}=1.514\times 10^{-7}[/tex]

I have two beakers (A & B) containing clear liquids. The first one (A) holds 75g and after being analyzed proves to contain 4.425g of hydrogen and 70.575g of oxygen. The second beaker (B) holds 125g and analysis shows that it is composed of 7.38g of hydrogen and 117.6g of oxygen.

Answers

Answer:

The solutions are most likely hydrogen peroxide since it is the compound of hydrogen and oxygen that has a ratio of Hydrogen to Oxygen ratio of 1 : 1.

Note:The question is not complete.

Explanation:

The empirical formula of the two compounds are determined

Solution in beaker A:

Mass of Hydrogen = 4.425 g

Moles of hydrogen = reacting mass/molar mass = 4.425 g / 1 g/mol = 4.425 moles

Mass of oxygen = 70.575 g

Moles of oxygen = reacting mass/molar mass = 70.575 g / 16 g/mol= 4.411 moles

Mole ratio of Hydrogen to Oxygen = 4.425 : 4.411

Simplest mole ratio = 1 : 1

Therefore, empirical formula of solution in A = H₁O₁

Solution in beaker B:

Mass of Hydrogen = 7.38 g

Moles of hydrogen = reacting mass/molar mass = 7.38 g / 1 g/mol = 7.38 moles

Mass of oxygen = 117.6 g

Moles of oxygen = reacting mass/molar mass = 117.6 g / 16 g/mol= 7.35 moles

Mole ratio of Hydrogen to Oxygen = 7.38 : 7.35

Simplest mole ratio = 1 : 1

Therefore, empirical formula of solution in B = H₁O₁

The solutions in beakers A and B have the same empirical formula. Their molecular masses are not given, so their molecular formula is not certain. However, the solutions are most likely hydrogen peroxide since it is the compound of hydrogen and oxygen that has a ratio of Hydrogen to Oxygen ratio of 1 : 1.

Chemical Bonding refers to the formation of a chemical bond between two or more atoms, molecules, or ions to give rise to a chemical compound.

These chemical bonds are what hold the atoms in the resulting compound together.

A chemical bond is a bond formed when the atoms in a compound's molecule combine and are held together by a strong combining force.

Chemical bonds are classified into two types namely ionic bonds and covalent bonds.

Chemical bonding enables scientists to combine the elements of the periodic table in a variety of ways to create chemical compounds and materials.
