The odd of being injured if a collision occurs as a result of increasing speed to 65 on a 55 mph road zone is 24%.

Speed limits are set for safety, to reduce the likelihood of crashes, and reduce the likelihood of getting injured should crashes occur.

In a report released by the National Cooperative Highway Research Program in 2006, breaching the maximum on a road with a speed limit increases the likelihood of crashes and getting injured as a result.

Specifically, increasing the speed to 65 on a road with a 55 mph speed limit increase the chances of crashes by 5% while increasing the chances of getting injured as a result by 24%.

Explanation:

aluminum oxide made of moles or atoms less then other elements need to decrease

Reaction

SiCl₄+ 2Mg ⇒ Si + 2MgCl₂

to find limiting reagents: divide the number of moles by their coefficients

SiCl₄ = 1 mole : 1 (coefficient) = 1

Mg = 5 mole : 2 (coefficient) = 2.5

SiCl₄ as a limiting reactant (smaller), and Mg as an excess

then all the compounds involved in the reaction are based on moles of SiCl₄

Si produced =

[tex]\tt \dfrac{coefficient~Si}{coefficient~SiCl_4}\times mole~Si=\dfrac{1}{1}\times 1=1[/tex]

Reacted Mg (excess) = 2/1 x 1 = 2 mole

mole Mg remaining = 5 - 2 = 3 mole

Explanation:

Answer:

V = 250 cm3

= 250 × 10^(-3) dm3

= 1/4 dm3

no. of mole = 0.2×1/4 mol

= 0.05 molExplanation:

Total , 0.050 moles of sodium chloride (NaCl) is required to prepare 250 cm³ of a 0.200 mol/dm³ solution.

To calculate the amount of NaCl (sodium chloride) in moles required to prepare a 0.200 mol/dm³ solution in a volume of 250 cm³, you can use the formula:

Amount of substance (in moles) = Concentration × Volume

Given:

Concentration (C) = 0.200 mol/dm³

Volume (V) = 250 cm³

First, convert the volume to dm³:

Volume (V) = 250 cm³ = 250/1000 dm³

= 0.250 dm³

Now, use the formula to calculate the amount of NaCl in moles:

Amount of NaCl = Concentration × Volume

Amount of NaCl = 0.200 mol/dm³ × 0.250 dm³

Amount of NaCl = 0.050 moles

Therefore, 0.050 moles of NaCl is required to prepare 250 cm³ of a 0.200 mol/dm³ solution.

A.) Carbon

Explanation:

Carbon:
Living things want carbon to measure, grow, and reproduce. Carbon could be a finite resource that cycles through the planet in several forms. This makes carbon obtainable to living organisms and remains in balance with different chemical reactions within the atmosphere and in bodies of water like ponds and oceans.

Oxygen:
Cellular respiration describes the part of the organic process once food breaks right down to offer cells energy. Throughout internal respiration, cells use oxygen to interrupt sugar to provide ATP or nucleotides.

Hydrogen:
Hydrogen plays a vital role in energy production within the body. For our bodies to operate, they have to have energy within the type of nucleotide or ATP. Your body gains energy by overwhelming foods wealthy in substances like carbohydrates.

All household electrical circuits are wired in parallel with each other; there's nothing special about fluorescent lights. This is so that the full 120 volts is presented to each device. If you put devices in series, they will "share" the voltage, say 70 volts to one device and 50 volts to the second (adding up to the 120 volts in the circuit).

The equation is the representation of the chemical reaction. The reaction to be added to equation 1 to produce equation 2 is [tex]\rm 3\;CO\;+\frac{1}{2}\;O_2\;\rightarrow\;CO_2[/tex].

The chemical reaction is the change in the reactant for the formation of the product.

The given equation 1 has been:

[tex]\rm Fe_2O_3\;\rightarrow\;2\;Fe+2\;O_2[/tex]

The final reaction 2 has been:

[tex]\rm Fe_2O_3+3\;CO\;\rightarrow\;2\;Fe+3\;CO_2[/tex]

The reaction with carbon to utilize the reactant oxygen of reaction 1 forming carbon dioxide, results in reaction 2.

When calcium oxide (chemical formula: CaO) reacts with water (chemical formula: H

2

​

O), the following reaction takes place:

CaO+H

2

​

O→Ca(OH)

2

​

he product of this reaction is calcium hydroxide, also known as slaked lime.

Thus, when calcium oxide reacts with water, slaked lime is produced.

Calcium oxide is also known as lime and is most commonly used for many purposes. It can be used for pH correction of water or for its disinfection (with excess lime). More importantly, lime has been used for a very long time to produce calcium carbonate by reaction with carbon dioxide. Calcium carbonate has been used as mortar for sealing the gaps between bricks, stones, etc.

The reaction for the production of calcium carbonate is:

CaO+CO

​

→CaCO

In reality the reaction is a two-step process, with formation of slaked lime in the first step and reaction of slaked lime with carbon dioxide to form calcium carbonate in the second.
