Answer:

Answer Below

Explanation:

Your feet and hands are thin compared to the rest of your body. Thin stuff has a large surface area compared to volume. Surface area is where you lose heat and volume is where you generate heat. Because of this, they lose heat quickly and do not generate enough heat to stay warm. To fix this your body also moves heat around from your warm core to your hands and feet using your blood. Your blood is warm. It gets to be that way because it runs through areas, mostly in your torso, that are always warm

Answer:

Investigating a data breach

Explanation:

A data breach usually involves data exfiltration over a computer network. the other options involve data being stored on a device locally which isn't volatile data like text messages, photos or rearranging data in defragmentation all of which does not require a network.

Answer:

The correct answer is "[tex]1.21\times 10^5 \ Pa[/tex]".

Explanation:

The given values are:

Number of moles,

n = 2.5 moles

Volume,

V = 45 liters

Temperature,

T = 261 K

As we know,

⇒  [tex]PV=nRT[/tex]

or,

⇒  [tex]P=\frac{nRT}{V}[/tex]

On substituting the values, we get

⇒      [tex]=\frac{2.5\times 0.0821\times 261}{45}[/tex]

⇒      [tex]=\frac{53.57}{45}[/tex]

⇒      [tex]=1.19 \ atm[/tex]

On converting it in Pa, we get

⇒      [tex]=1.19\times 1.01325\times 10^5[/tex]

⇒      [tex]=1.21\times 10^5 \ Pa[/tex]

2.85 grams

4.28x10^2 atoms (40.08 grams of Ca/ 6.02x10^23)

Answer:

(9.03x10^-14)x(8.455x10^20)=7.634865x10^7

(5.2x10^11)/(2.10x10^-4)=2.476190x10^15

(7.67x10^12)x(3.8x10^15)=29146000000000000000000000000

(9.237x10^20)/(4.5x10^-6)=2.0526x10^26

Explanation:

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]

We have

[tex]P_2 = \frac{0.5 \times 150}{75} = \frac{75}{75} = 1 \\ [/tex]

We have the final answer as

Answer:

inversely proportional

Explanation:

Answer:

Amphoteric oxide is an oxide that reacts with both acids and bases. In other words, it possesses both acidic and basic properties. For example both zinc and aluminium are metals but their oxides, ZnO and Al2O3 are amphoteric oxides as they react with both acids and bases.

Explanation:

Answer:

It says that the energy (E) in a system (an atom, a person, the solar system) is equal to its total mass (m) multiplied by the square of the speed of light (c, equal to 186,000 miles per second).

Explanation:

Answer: 16.0 g

Explanation: M(NaOH) = 39.998 g/mol. N = m/M = cV

Mass m = McV = 39.998 g/mol·0.200 mol/l · 2.0 l = 16.0 g

Answer:

5.83 M

Explanation:

3.5 M * 125.0 ml  =  M₂ * 75.0ml

437.5 M.ml = M₂ * 75.0 ml

M₂ = 437.5 M.ml / 75.0 ml

M₂ = 5.83 M

Answer:

-217 kJ

Explanation:

ΔH =  reactant energy - product energy

ΔH = [(C-H) × 2 + (C≡C)] + [2 × H-I] - [(I-C) × 2 + (C-H) × 4 + (C-C)]

ΔH = [ (413 × 2 ) + 839 + 2(299)]  - [(240 × 2) + (413 × 4) + 348]

ΔH = [826 +839 + 598] -  [ 480 +1652 + 348]

∴ ΔH = -217

Answer:

We will increase the temperature for a solution to be dissolved more into water.

To form a solution, energy is required to break the particles. If more energy is required to break the bonds of solute and solvent than the energy is released, then its called endothermic reaction.

For an endothermic solution, we would have to provide heat / temperature (energy) so that more solute can be dissolved in water which can increase the rate of solution.

Answer:

The white stuff we know as sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). Like all compounds made from these three elements, sugar is a carbohydrate

Answer:

2.114 atm

Explanation:

Since it is just pressure and volume, use Boyle's Law

P1V1 = P2V2

Then plug in numbers

(1 atm)(1 L) = P2(.473 L)

P2 = 2.114 atm

Answer:

[tex]\boxed {\boxed {\sf 3.94 *10^{23} \ molecules \ C_6 H_ {14} }}}[/tex]

Explanation:

1 mole of any substance has the same number of particles: 6.022 * 10²³. This number is as Avogadro's Number.

The particles can be molecules, atoms, formula units, etc. For this problem, the particles are molecules of C₆H₁₄ or hexane.

We can set up a ratio using Avogadro's Number.

[tex]\frac {6.022 *10^{23} \ molecules \ C_6H_{14}}{1 \ mol \ C_6H_{14}}[/tex]

Multiply by the given number of moles: 0.655

[tex]0.655 \ mol \ C_6H_{14} * \frac {6.022 *10^{23} \ molecules \ C_6H_{14}}{1 \ mol \ C_6H_{14}}[/tex]

The moles of hexane will cancel, because one is the "numerator" (techincally 0.655 is over 1) and the other is in the denominator of the ratio.

[tex]0.655 * \frac {6.022 *10^{23} \ molecules \ C_6H_{14}}{1 }[/tex]

[tex]0.655 * {6.022 *10^{23} \ molecules \ C_6H_{14}}[/tex]

[tex]3.94441*10^{23} \ molecules C_6H_{14}[/tex]

The original value of moles has three significant figures, so our answer must have the same. For the number we found, that is the hundredth place.

The 4 in the thousandth place tells us to leave the 4 in the hundredth place.

[tex]3.94 *10^{23} \ molecules \ C_6H_{14}[/tex]

0.655 moles of hexane is equal to approximately 3.94 *10²³ molecules of hexane.

Answer:

New pressure = 42216.66 Pa

Explanation:

Given that,

Initial volume, V₁ = 5 m³

Final pressure, P₁ = 101320 Pa

Final volume, V₂ = 12 m³

We need to find the final pressure of the gas. We know that the relation between pressure and volume is given by :

[tex]P\propto \dfrac{1}{V}\\\\P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{101320 \times 5}{12}\\\\P_2=42216.67\ Pa[/tex]

So, the new pressure is equal to 42216.66 Pa.

Answer:

It represents a decomposition reaction because one reactant breaks apart and forms two products

Explanation:

Your welcome

To solve such this we must know the concept of redox reaction. Therefore, the correct option is option C. It represents a decomposition reaction because one reactant breaks apart and forms two products.

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

Decomposition reaction is a chemical reaction where one reactant breaks down into two or more than two products on supplying energy in form of heat or electricity.

Therefore, the correct option is option C. It represents a decomposition reaction because one reactant breaks apart and forms two products.
