In general, people of __ heritage will be the last to get

white hair.

Answer:

Below

Explanation:

In a chemical reaction, per the law of conservation of mass, no atoms or subatomic particles will be created or destroyed; for example, H2O2 will decompose into H2 and O2, meaning no matter was created or destroyed.

Answer:

A

Explanation:

A liquid will will have the same color, it will not have the same shape and its volume will always be constant because you are not creating mass.

Hope this helps!

The formula for calculating the amount of energy or heat released is:

ΔH = C ΔT

where ΔH is heat of combustion, C is heat capacity, while ΔT is change in temperature

ΔH = 8.69 kJ / °C * (5.14°C)

ΔH = 44.67 kJ

Then we calculate the moles of CH3OH which has molar mass of 32.04 g/mol:

moles = 1.922 / 32.04 = 0.05999 mol

SO the molar heat of combustion is:

ΔHm = 44.67 kJ / 0.0599875 mol

ΔHm = 744.60 kJ / mol

One approach focuses on tradition, while the other focuses on the treatment of women in their culture the response is cultural value. Hence option A is correct.

Traditions are defined as a notion or practice  that has been passed down within a community or society and has unique importance or symbolic value that dates back in time. Traditions are notions and convictions that are passed down from generation to generation.

Cultural value are defined as the fundamental values and concepts that underpin a community's existence and provide a foundation for its protection and reliance on peaceful coexistence. Cultural values are the fundamental notions of right and wrong held by a culture.

Thus, one approach focuses on tradition, while the other focuses on the treatment of women in their culture the response is cultural value. Hence option A is correct.

ABRAHAM DIDN’T THINK ISAAC WOULD DIE!

When they reached the mountain, Abraham told his servant, “Stay here with the donkey; I and the boy will go over there and worship and come again to you” . The text is careful to include both Abraham and Isaac in the return journey.

Or consider Isaac’s question about where the lamb for the sacrifice would come from. Abraham responds, “God himself will provide the lamb”. It seems Abraham prepared himself to do what God asked, but he expected something else to happen.

The author of the book of Hebrews gives us insight to Abraham’s thoughts. It says, “He considered that God was able even to raise [Isaac] from the dead” Instead of a resurrection, Abraham was spared the sacrifice.

The setup above is used to collect hydrogen gas

Both filtration and distillation are useful ,methods to purify or separate components of a mixture. To collect soluble gas such as ammonia the best method is distillation. Thus setup 2 is better for collection of solute.

Distillation is the process of separation of compounds using  heat and condenser. The mixture is first boiled to the boiling point of solvent. When it is heated the solvent such as water passes from the beaker on which the mixture is taken.

The steam of the solvent is then cooled in the condenser tube and then liquid is collected to a second beaker. Therefore, the solute remains in the first beaker and can be collected.

Using filtration, we can only separate solution with insoluble solutes. Using filter paper the solid from the solution can be separated out.

First set up shows the filtration method  which is not applicable for collecting soluble gas like ammonia. Therefore, the second setup that is distillation is better to collect soluble gases.

Answer:

sensory experience of a chemical reaction called combustion. In a way, fire is like the leaves changing color in fall, the smell of fruit as it ripens, or a firefly's blinking light. All of these are sensory clues that a chemical reaction is taking place

Explanation:

Sensory encounter with the combustion chemical process. Fire can be compared to the fall foliage's shifting hues, the aroma of ripe fruit, or the blinking light of fireflies. These are all sensory indicators that a chemical reaction is occurring.

Combustion is defined as a chemical interaction between different compounds, usually involving oxygen, that produces heat and light in the form of flames. Hydrocarbons and oxygen are the only reactants in a combustion reaction. The fuel is a hydrocarbon, and oxygen is required for burning.

It stimulates several of our senses at once, producing the vivid experience we anticipate from a tangible object. By using fuel, heat, and oxygen during combustion, that sensory experience is produced.

Thus, sensory encounter with the combustion chemical process. Fire can be compared to the fall foliage's shifting hues, the aroma of ripe fruit, or the blinking light of fireflies. These are all sensory indicators that a chemical reaction is occurring.

A bomb calorimeter with a heat capacity of 3.63 kJ/°C experiences a temperature rise of 4.21 °C when .8210 g of naphthalene is burned.

The combustion of naphthalene is used to calibrate the heat capacity of a bomb calorimeter.

It is a device used to measure the change in the internal energy of a reaction.

To determine the heat capacity of the calorimeter (C), we need to follow a series of steps.

The heat of combustion of naphthalene is -40.1kJ/g and .8210g were burned.

Qcomb = -40.1kJ/g × .8210g = -32.9 kJ

According to the law of conservation of energy, the sum of the heat released by the combustion and the heat absorbed by the bomb calorimeter is zero.

Qcomb + Qbomb = 0

Qbomb = -Qcomb = 32.9 kJ

32.9 kJ were absorbed, part by the calorimeter itself and part by the 1,000 g (m) of water, whose specific heat capacity (c) is 4.18 J/g°C.

A temperature rise (ΔT) of 4.21 °C is observed. We can determine the heat capacity of the bomb calorimeter (C) using the following expression.

Qbomb = Qcal + Qwater

32.9 kJ = C × ΔT + c × m × ΔT

32.9 kJ = C × 4.21 °C + (4.18 × 10⁻³ kJ/g.°C) × 1,000 g × 4.21 °C

C = 3.63 kJ/°C

Answer:

because those are the only thermometers that are truly accurate for kelvins

Explanation:

The Kelvin temperature in thermometers is used by scientists because it provides a temperature where zero indicates the complete absence of thermal energy.

All thermometers have a scale on them that we use to find the temperature, known as a temperature scale. Kelvin proposed that the temperature interval from the ice point to the steam point be defined as 100° containing earlier centigrade scales.

Lord Kelvin had given an absolute temperature scale based on the Carnot cycle.  The zero point is 273.15 on Kelvin’s scale below that of the Celsius scale.

On the kelvin scale, Each division is called a Kelvin (K) and is equal to a degree on the Celsius scale. On the Celsius scale, zero degrees is the freezing point of water while on the Kelvin scale the zero point is at absolute zero temperature.

Therefore, 0 K is equal to - 273.15°C, and 0°C is equal to 273.15 kelvins. A mathematical expression that gives the relation between the Celsius and Kelvin scales:

Temperature (K) = Temperature (°C) + 273
