Which of the following is the general format for a double displacement reaction?

Physics
2 answers:
Shkiper50 [21]3 years ago
8 0

Answer:

AX + BY  → AY + BX

Explanation:

In double displacement reaction, the cations and anions of the two compounds switch places and form two new compounds. Exchange of bonds takes place. One of the product usually precipitates.

AX + BY  → AY + BX

In this general format, AX and BY compounds react, X and Y exchange places and form different compounds (AY and BX).

This is the general format for a double displacement reaction
A + B = AX + BY
It would be the fourth option.

A 100g block is initially compressing a spring 5.0 cm. The spring launches the block 50cm horizontally along the ground with a f
Setler [38]

Answer:

7200 N/m

Explanation:

Metric unit conversion

100g = 0.1 kg

5 cm = 0.05 m

50 cm = 0.5 m

As the block is released from the spring and travelling to height h = 1.5m off the ground, the elastics energy is converted to work of friction force and the potential energy at 1.5 m off the ground

The work by friction force is the product of the force F = 15N itself and the distance s = 0.5 m

W_f = F_fs = 15*0.5 = 7.5 J

Let g = 10 m/s2. The change in potential energy can be calculated as the following:

E_p = mgh = 0.1*10*1.5 = 1.5 J

Therefore, as elastic energy is converted to potential energy and work of friction:

E_e = W_f + E_p

kx^2/2 = 7.5 + 1.5 = 9 J

k = 9*2/x^2 = 18/0.05^2 = 7200 N/m

3. A car has a mass of 1000kg. What is its weight?<br><br> A) 9.81x10 ^ 3N<br> B) 1.89x10 ^ 3N
Strike441 [17]

Answer

A

Explanation:

Weight = Mass x Acceleration due to gravity

Weight = 1000 x 9.81

= 9810 or 9.81x10^ 3

A radio station broadcast on a frequency of 3.7 mhz what is the energy of the radio wave
Ratling [72]

A radio station broadcast on a frequency of 3.7 mhz what is the energy of the radio wave A radio station broadcasts its programmes at a wavelength of 500 m. Find the frequency of the radiowaves transmitted by the radio station, if the speed of radiowaves in air is 3 x 108 m/s. Ans: 6 x 10 Hz

<h3>What is radio station ?</h3>

Radio broadcasting is the act of sending audio (sound), occasionally together with accompanying metadata, across radio waves to radio receivers used by the general public. Unlike satellite radio, which uses a satellite in Earth's orbit, terrestrial radio broadcasting uses a land-based radio station to transmit radio waves. The listener needs a broadcast radio receiver to hear the material (radio). A radio network with which stations frequently have affiliations provide content in a standard radio format, whether through broadcast syndication, simulcasting, or both. Radio stations use a variety of modulations to transmit their signals, including FM (frequency modulation), which is an older analog audio standard, and AM (amplitude modulation).
