Answer:

2NaBr + CaF₂ ⟶ 2NaF + CaBr₂

Explanation:

Put a 1 in front of the most complicated-looking formula (CaF₂?):

                       NaBr + 1CaF₂ ⟶ NaF + CaBr₂

Balance Ca:    NaBr + 1CaF₂ ⟶ NaF + 1CaBr₂

Balance F:      NaBr + 1CaF₂ ⟶ 2NaF + 1CaBr₂

Balance Na: 2NaBr + 1CaF₂ ⟶ 2NaF + 1CaBr₂

————————————————————

<em>Check</em>

<u>Atom</u>  <u>On the left</u>  <u>On the right </u>

  Na             2                   2

  Br              2                   2

  Ca             1                     1

  F               2                    2

The balanced equation is

2NaBr + CaF₂ ⟶ 2NaF + CaBr₂

How did you use QPOE?​
Jlenok [28]

QPOE Files

The x-ray data are stored in QPOE files (Quick Position-Ordered Events, *.qp) rather than image arrays. These are lists of photons identified by several quantities, including the position on the detector, pulse height, and arrival time. Note that, unlike IRAF images, QPOE files have no associated header file, and are always stored in the current directory, unless explicitly specified otherwise. Non-PROS IRAF tasks can also access QPOE data files in place of image arrays.

Calculate the final Celsius temperature when 634 L at 21 °C is compressed to 307 L.
Illusion [34]

Answer:

- 130.64°C.

Explanation:

  • We can use the general law of ideal gas:<em> PV = nRT.</em>

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

  • If n and P are constant, and have two different values of V and T:

<em>V₁T₂ = V₂T₁</em>

<em></em>

V₁ = 634.0 L, T₁ = 21.0°C + 273 = 294.0 K.

V₂ = 307.0 L, T₂ = ??? K.

<em>∴ T₂ = V₂T₁/V₁ </em>= (307.0 L)(294.0 K)/(634.0 L) = <em>142.36 K.</em>

<em>∴ T₂(°C) = 142.36 K - 273 = - 130.64°C.</em>

A shiny, smooth piece of black plastic and an identical piece of white plastic are exposed to visible light and sound waves. Whi
Nana76 [90]

Answer:

The awnser is D

Explanation:

Since the black pieces absorb light better than white pieces, the white pieces will reflect light better. But since color doesn't affect sound, the sound waves are reflected the same.
