Answer: 2LiI(aq)+Hg_2(NO_3)_2(aq)\rightarrow Hg_2I_2(s)+2LiNO_3(aq)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

Precipitation is a type of displacement reaction in which one the products is formed in the solid state.

2LiI(aq)+Hg_2(NO_3)_2(aq)\rightarrow Hg_2I_2(s)+2LiNO_3(aq)

Problem: If you push an object with a constant force of 100 N over a 10-meter distance. How much energy transfer occurs on the o
Sveta_85 [38]

The energy transferred on the object is 1000 Joules.

Given:

An object on which a constant force of 100 N was applied to displace it over a distance of 10 meters.

To find:

The energy transfer occurs on the object.

Solution

The force applied on the object = F = 100 N

The displacement of the object = d = 10 m

The energy transferred on the object or work done is given by:

W = F\times d\\W=100 N\times 10 m = 1,000 J

The energy transferred on the object is 1000 Joules.

How many moles of CO2 are produced
Sergio039 [100]

Answer:

30.0 mol CO₂

Explanation:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

To answer this problem we need to convert moles of C₃H₈ into moles of CO₂: We'll do that by using the <u>stoichiometric coefficients</u>, using a conversion factor that has C₃H₈ moles in the denominator and CO₂ moles in the numerator:

10.0 mol C₃H₈ * \frac{3molCO_2}{1molC_3H_8} = 30.0 mol CO₂

Consider the condensed structure shown.
neonofarm [45]

Answer:

C_{5}H_{10}\:C_{2}H_{6}

Explanation:

Expanded Structure shows all the atoms and the bonds of the molecule. It is important to remember, each Carbon molecule have four bonds, while the Hydrogen just one. So:

1)C_{5}H_{10}

Pentene. 5 Carbon molecules, 10 Hydrogen molecules. It's an isomer, so this organic compound has multiple arrangements.

2) C_{2}H_{6}

Ethane. 2 Carbon and 6 Hydrogen Molecules. Check it below.
