Examine the reactants of the incomplete double displacement reaction.
Bumek [7]
<h3>Answer:</h3>

AgCl + NaNO₃

<h3>Explanation:</h3>
  • The reaction between silver nitrate and sodium chloride is an example of a double displacement reaction.
  • In a double displacement reaction compounds or salts reacts and exchange cations or anions to form new compounds or salts.
  • In this case, silver nitrate and sodium chloride exchange anions and cations to form silver chloride and sodium nitrate.
  • Therefore, the complete reaction is given by;

AgNO3 + NaCl → AgCl + NaNO₃

  • But since silver chloride is a precipitate, the reaction may also be an example of a precipitation reaction.

A bicyclist traveling at 5 m/s hits a fence, the bicyclist files over the fence. Which
Margarita [4]

The Newton's Laws that BEST describe the situation is Newton's second law of motion.

<h3>What is Newton's second law of motion?</h3>

Newton's second law of motion states, the force exerted by an object is directly proportional to the product of mass and acceleration of the object.

Also, the law can also be states as force is equal to the rate of change of momentum.

F ∝ Δp

Ft = m(v2 - v1)

The force exerted on the bicyclist by the fence is equal to the change in momentum of the bicyclist. The bicyclist was able to fly over the fence because there is a change in his momentum.

Thus, the Newton's Laws that BEST describe the situation is Newton's second law of motion.

Can anyone plz give me a right answer now?
grandymaker [24]

Answer:

Dy = - 0.0789 [m]

Explanation:

The vertical component of the vector can be determined with the sine of the angle.

Dy = 0.250*sin(18.4)

Dy = 0.0789 [m]

As the y-component is pointing downwards the component is negative.

Dy = - 0.0789 [m]

8) Granite has a specific heat of 800.00J/gºC. What mass of granite is needed to store 150,000.00J
uysha [10]

Answer:

Explanation:

specific heat of granite  S = 800 J /g°C

increase in temperature = 15.5 °C .

mass  = m ( let )

Heat needed to raise temp  = mass x specific heat x rise in temperature

150,000 = m x 800 x 15.5

m = 12.096 g .
