Of the reactions below, which one is a double-replacement reaction?
MakcuM [25]
<h3><u>Answer;</u></h3>

D. Cd(NO3)2 + Na2S -> CdS + 2 NaNO3​

<h3><u>Explanation;</u></h3>
  • <u>A double displacement reaction</u> is a type of chemical reaction that takes place when two compounds reacts, and the positively charged ions or cations and the negatively charged ions or anions of the two reactants switch places resulting to the formation of two new compounds.
  • In this case; t<em><u>he reaction Cd(NO3)2 + Na2S -> CdS + 2 NaNO3​; is an example of double displacement reaction, in which Cd2+ ions in Cd(NO3)2 switch places with Na+, while NO3- in Cd(NO3)2 switch places with S^2- in Na2S, to form two new compounds CdS and  NaNO3​. </u></em>

A patient is given 200 mg of a drug with the formula: C32H34N6O10. How many mg of the drug is carbon?
Mice21 [21]

200 mg of C₃₂H₃₄N₆O₁₀ contains 116 mg of carbon.

To obtain the answer to the question, we'll begin by calculating the molar mass of C₃₂H₃₄N₆O₁₀. This can be obtained as follow:

Molar mass of C₃₂H₃₄N₆O₁₀ = (12×32) + (1×34) + (14×6) + (16×10)

= 384 + 34 + 84 + 160

<h3>= 662 g/mol </h3>

From the molar mass of C₃₂H₃₄N₆O₁₀, we can see that:

<h3>662 g of C₃₂H₃₄N₆O₁₀ contains 384 g of carbon. </h3>

Converting 662 g of C₃₂H₃₄N₆O₁₀ to mg, we have

1 g = 1000 mg

Therefore,

662 g = 662 × 1000

<h3>662 g of C₃₂H₃₄N₆O₁₀ = 662000 mg</h3>

Converting 384 g of carbon to mg, we have,

1 g = 1000 mg

Therefore,

384 g = 384 × 1000

<h3>384 g of carbon = 384000 mg</h3>

Thus, we can say that:

662000 mg of C₃₂H₃₄N₆O₁₀ contains 384000 mg of carbon.

Finally, we shall determine the mass (in mg) of carbon in 200 mg of C₃₂H₃₄N₆O₁₀. This can be obtained as follow:

662000 mg of C₃₂H₃₄N₆O₁₀ contains 384000 mg of carbon.

Therefore, 200 mg of C₃₂H₃₄N₆O₁₀ will contain = \frac{200 * 384000}{662000} = 116 mg of carbon.

Thus, we can conclude that 200 mg of C₃₂H₃₄N₆O₁₀ contains 116 mg of carbon.

What is the speed of a man that travels 2 meters in 6.5 seconds?
sergij07 [2.7K]

Answer:

0.305556 m / s

Explanation:

Speed = distance / time

2 metres = 0.002 km

6.5 sec = 0.00180556 hrs

Therefore,

Speed = 0.002 / 0.00180556

           =  1.1 km / hr

           = <u>0.305556 m / s</u>

Calculate the pH of a 2.0 M H2SO4 solution.
noname [10]
 <span>H2SO4 gives 2 moles oh H+ per mole of acid 

[H2SO4] = 2M so [H+] = 4M 

pH = -log(4) = -.6 

Therefore, the pH </span><span>of a 2.0 M H2SO4 solution is -0.6
