I believe the correct answer here is 6.2. Since you would have to multiply the specific heat of gold by the amount of gold by the new heat of the gold. So this would be:

0.031 x 10 x 20 = 6.2

DaniilM [7]

Answer:

The answer to your question is: letter A

Explanation:

A combination reaction is when there are two reactants that gives only one product.

a. 2SO2 + O2—> 2SO3                          This is a combination reaction,

                                                               2 reactants gives one product.

b. Zn + Cu(NO3)2–>Zn(NO3)2 + Cu     This is not a combination reaction,

                                                                it's a single replacement reaction.

c. 2H2O2–> 2H2O+O2                          This is a decomposition reaction

d. AgNO3 + NaCl → AgCl+NaNO3        THis is a double replacement reaction.

A sample of a pure compound that weighs 59.8 g contains 27.6 g Sb (antimony) and 32.2 g F (fluorine). What is the percent compos
Rama09 [41]

Answer:

53.85%

Explanation:

Data obtained from the question include:

Mass of antimony (Sb) = 27.6g

Mass of Fluorine (F) = 32.2g

Mass of compound = 59.8g

Percentage composition of fluorine (F) =..?

The percentage composition of fluorine can be obtained as follow:

Percentage composition of fluorine = mass of fluorine/mass of compound x 100

Percentage composition of fluorine = 32.2/59.8 x 100

= 53.85%

Therefore, the percentage composition of fluorine in the compound is 53.85%
