Perhaps you need the reaction between $CaCO_3$ and HCl:

$CaCO_3 + 2HCl\ \to\ CaCl_2 + CO_2 + H_2$

The polymer formed from the monomer ch2=ch–cn is select one:

podryga [215]

Answer:
None of the given options show polymer made up of H₂C=CH-CN (Acrylonitrile).

Explanation:
Acrylonitrile (H₂C=CH-CN) which is a monomer on self linkage results in a large chain polymer called as Polyacrylonitrile.
The structure of Polyacrylonitrile is as follow,

--(H₂C-CHCN-)n--

Where n shows the number of Acrylonitrile units joined together in the formation of Polyacrylonitrile. This polymerization reaction can take place by different mechanisms including free radical mechanism, acid catalyzed addition or base catalyzed addition reaction.

The polymerization is shown below,

Density is an intensive physical property that relates the mass of an object to its volume. Density, which is simply the mass of

xz_007 [3.2K]

Answer: 40731.8 grams of this gasoline would fill a 14.6gal tank

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

Given : Mass of gasoline = ?

Density of the gasoline = $0.737g/ml$

Volume of the gasoline = 14.6gal = 55267.01 ml (1gal=3785.41ml)

Putting in the values we get:

$0.737g/ml=\frac{mass}{55267.01ml}$

${\text {mass of gasoline}}=40731.8g$

Thus 40731.8 grams of this gasoline would fill a 14.6gal tank

Point E is located at (-2, 2) and point F is located at (4-6). What is the distance between

Flauer [41]

Answer:

10

Explanation:

Given endpoints:

E (-2,2) and F(4, -6)

To find the distance between two points;

Use the expression below;

D = $\sqrt{(y_{2} - y_{1} )^{2} + (x_{2} - x_{1})^{2} }$

x₁ = -2,

x₂ = 4

y₁ = 2

y₂ = -6

Insert the parameters and solve;

D = $\sqrt{(-6 - 2 )^{2} + (4 -+ 2)^{2} }$

D = $\sqrt{64+ 36 }$ = 10
