Answer:

The following are some ways of safely disposing of non-biodegradable waste.

1. Take them to a local recycling facility. Separate metal, plastic, glass, and other non-biodegradable waste and store them ready for recycling.

2. Combustion and energy recovery.

3. Disposal at sanitary facilities.

4. Reduce.

5. Landfills.

A chemistry student needs 50.0 g of methyl acetate for an experiment. By consulting the CRC Handbook of Chemistry and Physics, t

slamgirl [31]

Explanation:

As density is defined as the mass of a substance divided by its volume.

Mathematically, Density = $\frac{mass}{volume}$

It is given that mass is 50 g and density is 0.934 $g/cm^{3}$ .

Hence, calculate the volume of methyl acetate as follows.

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

0.934 $g/cm^{3}$ = $\frac{50 g}{volume}$

Volume = $53.53 cm^{3}$

or, = $53.53 ml$ (as 1 $cm^{3}$ = 1 mL)

Thus, we can conclude that the volume of methyl acetate the student should pour out is $53.53 ml$ .

drek231 [11]

Answer: Increase the rate of surface water evaporation

Irrigation is a process, in which the crops are supplied with water, to ensure their proper growth. Increased in the irrigation supply can be because of the environmental conditions like hot summer season or may be because of the type of soil is semi arid or arid means the soil does not retains moisture efficiently. This will result in increase in the rate of evaporation of the surface water.

Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail. Wh

astraxan [27]

The efficiency of any machine is given by:

efficiency = output obtained / input given

Substituting the values,
Efficiency = 105 / 150
Efficiency = 0.7

Converting this to a percentage, the efficiency of the hammer is 70%.
This is a fairly high efficiency, and this is due to the fact that the hammer is a simpler machine. The more complex a machine is, the greater are the losses in it due to friction, meaning there is a lower efficiency.

slega [8]

Answer:

${ \rm{F _{2(g)} + 2KCl _{(aq)} → { \bold{2KF _{(g)} + Cl_{2(g)} }}}}$

Explanation:

» The prediction is 98% correct because single displacement reaction type is highly possible.

This is because Fluorine has is more electronegative than Chlorine in Potassium Chloride. So, it strongly displaces Chlorine from the solution hence forming Chlorine gas.

» The 2% of wrong prediction maybe because of wrong reactant measurements following mole concept chemistry.

If you are asked the observation,

Observation » A green yellowish gas is formed.

This gas is Chlorine gas (Cl2)
