In the molecule, C2H4, what are the atomic
Angelina_Jolie [31]
<span>Ethene (C2H4) is an alkene which means this compound has a double bond between the carbons. The hybridization hence is sp2. In this hybridization, the 2s orbital mixes with only two of the three available 2p orbitals, forming a total of 3 sp2 orbitals with one p-orbital remaining.</span>

A box has the weight of 120N and the bottom of the box is 12 cm² what is the pressure the box exerts on the floor
Molodets [167]

100000N/m²

Explanation:

Given parameters:

Weight of the box = 120N

Area of the box = 12cm²

Unknown:

Pressure of the box on the floor = ?

Solution:

Pressure is the force exerted by a body per unit area:

            Pressure = \frac{force }{area}

We need to convert the area into m² from cm²

     10000cm²  = 1m²

      12cm²  =     \frac{12}{10000} = 0.0012m²

 Pressure = \frac{120}{0.0012} = 100000N/m²

Balance the equation ? c4h10 (g) + ? o2 (g) → ? co2 (g) + ? h2o (g), using the smallest possible integers. what is the coefficie
max2010maxim [7]
C4H10 (g) + (6.5) O2 (g) --> 4CO2 (g) + 5H2O (g)

Smallest coefficient of C4H10 is 1.

First, balance out the Carbon and Hydrogen atoms as they are limiting.

Second, calculate the number of Oxygen atoms and minus away those found in C4H10.

Divide the number with 2 as oxygen exists as O2. [It is OK to put a fraction in front of the molecule as long as there is 1 atom used in the reaction. ]

16. Explain why antifreeze is used in vehicle radiators. Use your knowledge of the properties of
Fynjy0 [20]

Answer:

Antifreeze is whats used to keep your engine cool without freezing.

Explanation:

it keeps the engine from overheating.

It also prevents corrosion.

Here is a quote from google "Antifreeze works because the freezing and boiling points of liquids are “colligative” properties. This means they depend on the concentrations of “solutes,” or dissolved substances, in the solution. A pure solution freezes because the lower temperatures cause the molecules to slow down"

That quote is from "The Science Behind Antifreeze"

If you have any questions feel free to ask in the comments.
