Answer:

Explanation:

Both Sample A and B have the same mass (5g) and same temperature change (15°C). What is not said and may explain the difference in energy needed are their initial states and temperature.

For example Sample B may be liquid water at 90°C. Heating it up to 105°C will require additional energy to go from liquid to gas state. If Sample A is water vapor at 105°C at first, it has a lower specific heat and heating it up to 120°C does not involve a state change. So the eneregy needed is less.

Answer:

Characteristics of tundra include:

Extremely cold climate.

Explanation:

By the time thermal equilibrium is attained in the system, ice is completely converted to water.

Thermal equilibrium is a situation in which two substances are exactly at the same temperature. That is. Heat is no longer flowing beween the bodies.

Recall that an insulated thermos flask implies that heat does not eneter or leave the system. Heat will flow from the water to the ice untill the both  attains the same temperature and the ice is completely converted to water.

Answer:

a jagged black line along the right side of the table separates the metals from the nonmetals. The metals are to the left of the line, the nonmetals are to the right of the line, and the elements immediately next to the line are the metalloids.

Explanation:

The electronic configuration helps to determine if the element is a metal or non-metal.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

This exercise is from Barbershop can keep men healthy by Joseph Ravenell, and is related to High Blood Pressure.

Mr. Ravenell describes the essence of the black barbershop as a place where there is friendship, trust and cooperation, and peace. (1a)

He considers it a safe haven because is void of stress and societal threats. (1b)

Some of the health-related topics that were discussed in the barbershop include but are not limited to:

Denny states that black men trust their barbers more than their doctors because most of them relate more with their barbers than with their doctors.

Mr. Ravenell taught barbers how to measure blood pressure, and how to counsel their customers to go see a doctor if their blood pressure was too high.

It was discovered that the number of those whose blood pressure were controlled in the 18 shops that were studied for one year were higher in the shops where the barbers had been trained.

Answer:

The total number of atoms must be the same on both sides in order for it to be a balanced chemical equation.

Explanation:

Answer: Five moles of CH4 would require ten moles of O2.

Explanation: Start with a balanced equation. You can see from the balanced equation that one mole of CH4 reacts completely with two moles of O2. So five moles of CH4 would require ten moles of O2.

Answer:

Atomic number is 30

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom it is also called nucleon number,

while the number of protons are number of electrons is the atomic number of an atom.

For example

if an element have 12 neutron and nucleon number is 42 it means the number of protons will be = nucleon number - number of neutrons

42 - 12 = 30

Thus atomic number is 30.

Answer:

30.

Explanation:

The nucleon or mass number is the total of protons and neutrons in the  nucleus.

Atomic number = nucleon number - number of neutrons in the nucleus

= 42 - 12

= 30.

Answer:

A derived unit is gained by adding two or more base quantities and in this case area is obtained by adding two more base quantities.

Quantity :Area = length(base quantity) × breadth(base quantity)

Derived unit of area = m(SI base unit ) × m(SI base unit) = m²

Answer: It is a molecular compound. (2) It contains a metal. (3) It can conduct electricity as a solid.

This problem is providing us with both the concentration and moles of a solute and asks for the volume in liters. At the end, the answer turns out to be 0.5 L according to the following.

In chemistry, units of concentration are used to represent the relative amounts of both solute and solvent in different units. In this case, we refer to molarity due to the relationship between the moles of solute and the volume of solution as follows:

[tex]M=\frac{n}{V}[/tex]

Thus, having both the concentration and moles, 10 M and 5 moles respectively, one can obtain the following volume after solving for it:

[tex]V=\frac{n}{M} =\frac{5mol}{0.5 mol/L}\\\\V=0.5 L[/tex]

The net ionic equation for the reaction between  KC₆H₇O₂ and HCl is:

C₆H₇O₂⁻(aq) + H⁺(aq) ⇒ HC₆H₇O₂(aq)

The net ionic equation is a chemical equation for a reaction that lists only those species participating in the reaction.

KC₆H₇O₂(aq) + HCl(aq) ⇒ HC₆H₇O₂(aq) + KCl(aq)

HC₆H₇O₂ is a weak acid so we will write it in the molecular form.

K⁺(aq) + C₆H₇O₂⁻(aq) + H⁺(aq) + Cl⁻(aq) ⇒ HC₆H₇O₂(aq) + K⁺(aq) + Cl⁻(aq)

We will not include spectator ions.

C₆H₇O₂⁻(aq) + H⁺(aq) ⇒ HC₆H₇O₂(aq)

Titrations test the pH level of an unknown solution by using a known solution.

A titration is a method in which a solution of known concentration is used to find out the concentration of an unknown solution. The titrant which is a known solution is added from a buret to the unknown solution until the reaction is complete.

So we can conclude that titrations test the pH level of an unknown solution by using a known solution.

The new volume of the gas at a temperature of 273 K and at pressure of 101.33 KPa is 706.01 L

The new volume of the gas can be obtained by using the combined gas equation as illustrated below:

P₁V₁ / T₁ = P₂V₂ / T₂

(303.98 × 250) / 290 = (101.33 × V₂) / 273

Cross multiply

290 × 101.33 × V₂ = 303.98 × 250 × 273

Divide both side by 290 × 101.33

V₂ = (303.98 × 250 × 273) / (290 × 101.33)

V₂ = 706.01 L
