Answers

Answer 1

Answer:

i) 2 C(s) + O2(g) → 2 CO

ii) Carbon monoxide poisoning occurs when carbon monoxide builds up in your bloodstream. When too much carbon monoxide is in the air, your body replaces the oxygen in your red blood cells with carbon monoxide. This can lead to serious tissue damage, or even death.

The iron oxide gets reduced.

The carbon gets oxidised.

the reason is that aluminium is more reactive than carbon to be extracted in a blast furnance.an element lying lower in the metal reactivity series can be reduced by carbon (a reducing agent) but aluminum lies above carbon metal series.

i) electrolysis.

ii) It is soft and malleable. Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts. This is because of its particular properties.

Which of these indicates that a liquid has transferred thermal energy to the air?
O The liquid increases in temperature, and its particles lose kinetic energy
O The liquid decreases in temperature, and its particles gain kinetic energy
O The liquid increases in temperature, and its particles gain kinetic energy.
O The liquid decreases in temperature, and its particles lose kinetic energy
No

Answers

Answer:

The liquid decreases in temperature and its particles lose kinetic energy.

Temperature is proportional to kinetic energy, so if temperature decreases, kinetic energy decreases. Energy has been removed from the liquid, because it is in the air

The liquid decreases in temperature,and its particales lose kinetic energy

Identify 5 factors of weather

Answers

Answer:

"The five factors are: the latitude zone, the elevation of the land, topography (landforms), ocean currents and winds."

Explanation:

Answer:

The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area's elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and thunderstorms resulting from air-mass differences; and the distribution of air pressure over the land and nearest oceans, which produces varying wind and air mass patterns.

If water is added to 145 mL of a 0.55 M KOH solution until the volume is 250 mL, what will the molarity of the diluted solution be?

Answers

Answer:

0.319 M

Explanation:

M1V1 = M2V2

M1 = 0.55M

V1=145 mL = 0.145 L

V2 = 250mL = 0.250L

M2 = M1V1/V2=0.55x0.145/0.250 = 0.319 M

It takes 5.54 mL of a 2.18 M NaOH solution to neutralize 6.19 mL of an HCl solution. What is the concentration of the HCl solution? Do not include units in your
answer. Round to the tenths place or further.

Answers

Answer:

2 M

Explanation:

NaOH + HCl --> NaCl + H2O,

5.54 mL = .00545 L,

If we consider 2.18 M, M [molarity] = mol/L, so we have 2.18 mol/L. From this we can get the moles of NaOH.

.00545 L * 2.18 mol/L ≈ .0121 mol

The concentration of HCl can be found from the following:

.0121 mol = .00619(x) [where x = concentration of HCl]

x = 1.955 M ≈ 2 M

We equate the two as we require the same amount in order to neutralize the base.

An independent variable is
a.
directly changed by the experimenter.
b.
manipulated by changes to the dependent variable.
C.
a variable that is kept constant.
d.
a variable that is used as a control.

Answers

Answer:

a. directly changed by the experimenter.

Explanation:

In the case of mathematical modeling, analytical modeling , and experimental sciences, the number of dependent variables based upon the amount of independent variables.

The dependent variables represent the result or outcome whose changes is being determined.

An independent variable expressed in the name form like experimental or expected variable, is a variable i.e. created in an experiment in order to verify the effect on a dependent variable

Therefore the option a is correct

An ideal gas occupies a volume V at an absolute temperature T. If the volume is halved and the pressure kept constant, what will happen to it's temperature?

a. It will halve to T/2.

b. It will increase to 3T.

c. It will increase to 2T.

d. It will remain the same.

Answers

Answer:

It will be halve of T

Explanation:

V1 = V

T1 = T

V2 = ½V

T2 = x

V1/T1 = V2/T2

V/T = ½V/x

Vx = ½VT

2Vx = VT

2x = T

x = ½T
