What is your standing regarding compostable plastics? Is it really environmental-friendly?

1 answer:

6 0

If a biodegradable plastic or bioplastic ends up in a landfill site it will never decompose. In landfill sites waste is essentially mummified, in a complete absence of light and oxygen. Food that has ended up in landfill will not biodegrade, so there is no hope for biodegradable plastics or even bioplastics.So it is bad.

For the reaction 2 NO(g) + 2 H2(g) => N2(g) + 2 H2O(g) the following data were collected. What is the rate law for this react

harkovskaia [24]

Answer: The rate law expression for the given reaction is written below.

Explanation:

Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

For the given chemical equation:

$2NO(g)+2H_2(g)\rightarrow N_2(g)+2H_2O(g)$

Rate law expression for the reaction:

$\text{Rate}=k[NO]^2[H_2]^2$

Hence, the rate law expression for the given reaction is written above.

If the symbol X represents a central atom, Y represents outer atoms, and Z represents lone pairs on the central atom, the struct

Inessa05 [86]

Answer:

The correct option is: bent 109°

Explanation:

Covalent molecules are the molecules in which the atoms are linked by covalent bonds. The electrons involved in the formation of a covalent bond are known as shared pair or bond pair of electrons.

The three-dimensional arrangement of the atoms of a molecule in space is known its molecular structure or geometry.

Given molecule: XY₂, having two lone pairs around the central atom X.

Since the molecule XY₂ has two lone pairs and two bond pairs of electrons. Therefore according to the VSEPR theory, the given molecule has a bent molecular geometry with 109° bond angle.

If a swimming pool contains 2,850 kiloliters (kL) of water, how many gallons (gal) of water does it contain? (1 gal = 3.785 L)

siniylev [52]

we are given

a swimming pool contains 2,850 kiloliters (kL) of water

2,850 kiloliters (kL)=2850000L

we know that

$1gal=3.785L$
