What type of front is depicted here? (60 Points)


Cold


warm


stationary


Occluded

Answer:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we're finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

120 kPa = 120,000 Pa

We have

[tex]P_2 = \frac{120000 \times 10}{3} = \frac{1200000}{3} \\ = 400000[/tex]

We have the final answer as

Answer:

d. Mg²⁺

Explanation:

c. K⁺

d. Mg²⁺

Based on the Bohr's atomic model, the atom has electrons (Mass 0; Charge -1), protons (Mass 1; Charge +1) and neutrons (Mass 1; Charge 0).

The atomic number is equal to the number of protons. That means there are 10 protons. As the Neon is netural, the amount of electrons must be 10.

A neutral atom of Mg has 12 electrons, that means the Mg²⁺ has 10 electrons the same than Ne.

Lowering the activation energy

Explanation:

A catalyst does not participate in the reaction, instead it offers the reaction an alternative pathway by lowering the activation energy. This new pathway is faster and the rate of reaction is increased.

Answer:

Doubled.

Explanation:

The relationship between the temperature and the volume of a gas at a constant pressure can be described using Charles' law:

That means that the temperature and the volume of a gas are directly proportional: The higher the temperature, the higher the pressure. If one of those factors is increased twofold, the other one will be increased twofold as well.

Answer:

200g of NaOH in powered form  will react with HCl at a faster rate

Explanation:

200g of NaOH in powered form  will react with HCl at a faster rate because it is in powdered form and it will have high surface area to volume ration and hence high reactivity and rate of reaction as compared to the cube NaOH.

Answer:

Acceleration

Explanation:

Acceleration doesn't change one moment to the next, and therefore, doesn't count as a force.

The answer option which is not a force is: C. Acceleration.

A force can be defined as a push or pull of an object or physical body, which typically results in a change of motion (acceleration), especially due to the interaction of the object with another.

In Science, the three (3) most common examples of a force include the following:

In conclusion, acceleration is not an example of a force but a change in the rate of velocity of an object with respect to time.

Answer:

anion

Explanation:

anion undergoes reduction.

cation undergoes oxidation.

The ions are categorized according to the process of oxidation and reduction. The ion usually undergoes reduction is an anion.

A process involving the partial or complete gain of electrons and loss of oxygen. The ions acquire a net negative charge on them.

Thus, anions usually undergo a reduction.

Explanation:

Convert Atoms to Moles

The first step is to convert atoms to moles. 1 mole of every substance has the same number of particles: 6.022 ×10²³ or Avogadro's Number. The type of particle can be different, in this case it is atoms of silver. Let's create a ratio using this information.

[tex]\frac{6.022*10^{23} \ atoms \ Ag}{1 \ mol \ Ag}[/tex]

We are trying to find the mass of 8.23 ×10²³ silver atoms, so we multiply by that number.

[tex]8.23 *10^{23} \ atoms \ Ag *\frac{6.022*10^{23} \ atoms \ Ag}{1 \ mol \ Ag}[/tex]

Flip the ratio so the atoms of silver cancel. The ratio is equivalent, but places the other value with units "atoms Ag" in the denominator.

[tex]8.23 *10^{23} \ atoms \ Ag *\frac{1 \ mol \ Ag}{6.022*10^{23} \ atoms \ Ag}[/tex]

[tex]8.23 *10^{23} *\frac{1 \ mol \ Ag}{6.022*10^{23} }[/tex]

Condense into one fraction.

[tex]\frac{8.23 *10^{23} }{6.022*10^{23} } \ mol \ Ag[/tex]

[tex]1.366655596 \ mol \ Ag[/tex]

Convert Moles to Grams

The next step is to convert the moles to grams. This uses the molar mass, which is equivalent to the atomic mass on the Periodic Table, but the units are grams per mole.

Let's make another ratio using this information.

[tex]\frac {107.868 \ g \ Ag}{1 \ mol \ ag}[/tex]

Multiply by the number of moles we calculated.

[tex]1.366655596 \ mol \ Ag*\frac {107.868 \ g \ Ag}{1 \ mol \ ag}[/tex]

The moles of silver cancel out.

[tex]1.366655596 *\frac {107.868 \ g \ Ag}{1 }[/tex]

[tex]1.366655596 * {107.868 \ g \ Ag}[/tex]

[tex]147.4184058 \ g\ Ag[/tex]

Round

The original measurement of atoms has 3 significant figures, so our answer must have the same. For the number we calculated, that is the ones place.

The 4 in the tenths place tells us to leave the 7 in the ones place.

[tex]147 \ g\ Ag[/tex]

8.23 ×10²³ silver atoms are equal to approximately 147 grams.

The solutes in a solvent can be make more soluble by heating. Thus upon heating the sugar lumps forming at the bottom of the water can be easily dissolved.

Solubility of substance is the fraction of its concentration which dissolves in a solvent. Solubility is affected by several factors such as temperature, pressure, molecular weight, bond type etc.

Water is known as universal solvent because, it can dissolve almost all the inorganic and organic compounds. The hydroxide ions in water forms hydrogen bonds with compounds and easily dissolve them.

By providing thermal energy the intermolecular attraction of the solute molecules can be weekend and they easily forms bonds with the solvent molecules results in dissolution. Thus option 1 is correct.

Answer:

1.43 grams

Explanation:

Fe = 55.8 grams Fe = 1 mole Fe

2.56 • 10^-3 moles Fe / 1 • 55.8 grams Fe / 1 mole Fe = 1.43 grams Fe

Basically, you're just multiplying the molar mass of Fe (iron) by the moles of 2.56 • 10^-3 Fe, to find how many grams are in it.

2.56 • 10^-3 moles Fe = 1.43 grams Fe
