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.

It is an open series circuit and this is why:

Pachacha [2.7K]

Answer:

p = \boxed{\text{593 torr}}

Explanation:

For this question, we must use Dalton's Law of Partial Pressures:

The partial pressure of a gas in a mixture of gases equals its mole fraction times the total pressure:

p = \chi p_{\text{tot}}

Data:

χ = 0.7808

p_{\text{tot}} = \text{ 760 torr}

Calculation:

p = 0.7808 \times \text{ 760 torr}\\\\p= \boxed{\textbf{593 torr}}
