The classification would be as follows:

<span>*water → hydrogen + oxygen = decomposition
*iron + oxygen → iron oxide = synthesis
*sodium + chlorine → sodium chloride = synthesis
*sulfur + oxygen → sulfur dioxide = synthesis
*potassium + chlorine → potassium chloride = synthesis
*calcium carbonate →calcium oxide + carbon dioxide = decomposition

Hope this answers the question. Have a nice day.</span>

Decomposition reactions are said to be those reactions in which a reactants breakdown into two or more products. The general reaction for decomposition reactions is as follow,

ABC → A + B + C

Specific Examples are as,

Water → Hydrogen + Oxygen

2 H₂O → 2 H₂ + O₂

Calcium carbonate → Calcium oxide + Carbon dioxide

CaCO₃ → CaO + CO₂

While, Synthetic reactions are said to be those reactions in which two or more reactants combine to form two or more products. The general reaction for synthetic reactions is as follow,

A + B + C → ABC

Specific Examples are as,

Iron + Oxygen → Iron Oxide

2 Fe + 3 O₂ → 2 Fe₂O₃

Sodium + Chlorine → Sodium chloride

2 Na + Cl₂ → 2 NaCl

Sulfur + Oxygen → Sulfur dioxide

S + O₂ → SO₂

Potassium + Chlorine → Potassium chloride

2 K + Cl₂ → 2 KCl

What is the wavelength of 7.0-TeV protons? A) 550 nm B) 750 nm C) 5.4x10^-15 m D) 3.2x10^-18 m E) 1.8x10^-19 m

AnnZ [28]

Answer:

1.776 x 10^-19 m

Explanation:

Energy, E = 7 TeV

Let λ be the wavelength.

Energy = h c / λ

Where, h is the Planks,s constant and c be the velocity of light

h = 6.63 x 10-^-34 Js

c = 3 x 10^8 m/s

Convert TeV into J

1 TeV = 1.6 x 10^-7 J

So, E = 7 x 1.6 x 10^-7 = 11.2 x 10^-7 J

11.2 x 10^-7 = (6.63 x 10^-34 x 3 x 10^8) / λ

λ = 1.776 x 10^-19 m

A disk with a radius of R is oriented with its normal unit vector at an angle Θ with respect to a uniform electric field. Which

marissa [1.9K]

Answer:

The expresion for the flux through the disk is:

Ф = E·πR^2·cos(Θ).

Explanation:

Let's sat the electric field has direction e and the normal to the disk has direction n (bold means vector quantities). So we have:

E=E·e (where E is the magnitud of the electric flied)

A=A·n

The flux for an uniform electric field and a flat surface is:

Ф=E×A

⇒ Ф = E·A·e×n = E·A·cos(angle(e,n)) = E·A·cos(Θ)

Since in this case the area is for a disk of radius R, $A=\pi R^{2}$

So, Ф = E·πR^2·cos(Θ)

A machine shop worker reports the mass of an aluminum cube as 176 g. If one side of the cube measures 4 cm, what is the density

Zarrin [17]

-- Since it's a cube, its length, width, and height are all the same 4 cm .

-- Its volume is (length x width x height) = 64 cm³ .

-- Density = (mass) / (volume)

= (176 g) / (64 cm³)

= 2.75 gm/cm³ .

The value of acceleration due to gravity (g) on Pluto is about . 0.61 meters/second2. How much will an object that weighs 250 ne

Annette [7]

First, determine the mass of the object by dividing its weight on Earth by 9.8 m/s² as shown below,
m = 250 N / 9.8 m/s² = 25.51 kg
Then, multiply the obtained mass by the acceleration due to gravity (g) on Pluto.
W (in Pluto) = (25.51 kg) x (0.61 m/s²) = 15.56 N
Therefore, the object will only weigh 15.56 N.
