What is the x-coordinate of the function below when the y-coordinate is 0?(0,5) (2,-5)

Chemistry
1 answer:
maria [59]4 years ago
4 0

The equation of the function is assumed to be a straight line is of the form,

y= mx+c,  where  m,c

are the gradient and the y intercept respectively.

The gradient is computed using the formula for the gradient, i.e

m=\frac{y_2-y_1}{x_2-x_1} =  \frac{-5-5}{2-0} = -5.

The equation of the line is,

y= -5x+c\\=>5=-5(0)+c\\=> c= 5


The equation of the function is ,

y = -5x+5..

The value of the x-coordinate when the y coordinate is 0 is found as shown below.

0=-5x+5\\=>x=1\\.

so the x-coordinate is 1.

Ence / Module 8<br> 5. How does water get back into the atmosphere in a rainforest after it rains?
Phantasy [73]

Answer:

The rooe of rainforests in the water cycle is to add water to the atmosphere through the process of transportation(which in plants release water from their leaves during photosynthesis). When forests are cut down, less moisture goes into the atmosphere and rainfall declines, sometimes leading to drought

A sample of cobalt has a mass of 27 g and a density of 9 g/cm^3. What would be its volume?
8_murik_8 [283]
Given ,

Mass of sample of cobalt = 27 g

density of sample of cobalt = 9g/cm^3

We know that ,

Density = mass of sample/volume of sample

From that relation ,

We can deduce the following as

Volume = mass of sample/density of sample

Hence , required volume of sample of cobalt = 27 g /9 g/cm^3 = 3 cm^3

The volume is \fbox{3cm cube}

Which of the following scenarios best illustrates the opponent-process theory of color vision?
Kitty [74]

Answer:

Kayla sees afterimages of opposing colors when she stares at a poster for a long time.

Explanation:

The "opponent-process theory" is a theory developed by <em>Edward Hering. </em>It states that<u> three color pairs</u>, which are opposing in nature, are linked by the cone receptors. These pairs are:

  • blue/yellow
  • red/green
  • black/white

This can be done when you stare at an<em> afterimage patch</em> for<u> 30 seconds.</u> Such as what Kayla is doing. Once the color stimuli is removed and she fixates her attention to a dot at the center of her field,<em> she'll notice the colors being reversed</em>. This means that if she sees the original color as<em> "blue,"</em> she'll see it now as <em>"yellow"</em> and<em> vice-versa</em>.

Extended inspection of a color in a pair results to it being <u>fatigued</u>. This allows the<u> non-fatigued color pair to be noticed</u>.

So, this explains the answer.

A student titrated 25.0 cm3 portions of dilute sulfuric acid with a 0.105 mol/dm3 sodium hydroxide solution.The equation for the
Rzqust [24]

Answer:

This question is incomplete

Explanation:

This question is incomplete as the volume of the base that was used during the titration was not provided. However, the completed question is in the attachment below.

The formula to be used here is CₐVₐ/CbVb = nₐ/nb

where Cₐ is the concentration of the acid = unknown

Vₐ is the volume of the acid used = 25 cm³ (as seen in the question)

Cb is the concentration of the base = 0.105 mol/dm³ (as seen in the question)

Vb is the volume of the base = 22.13 cm³ (22.1 + 22.15 + 22.15/3)

nₐ is the number of moles of acid = 1 (from the chemical equation)

nb is the number of moles of base = 2 (from the chemical equation)

Note that the Vb was based on the concordant results (values within the range of 0.1 cm³ of each other on the table) of the student

Cₐ x 25/0.105 x 22.13 = 1/2

Cₐ x 25 x 2 = 0.105 x 22.13 x 1

Cₐ x 50 = 0.105 x 22.13

Cₐ = 0.105 x 22.13/50

Cₐ = 0.047  mol/dm³

The concentration of the sulfuric acid is 0.047  mol/dm³

The strongest intermolecular interactions between propanol (CH3CH2CH2OH) molecules arise from hydrogen bonding
pickupchik [31]

The claim that the strongest intermolecular interactions between propanol molecules arises from hydrogen bonding is True.

Intermolecular forces are weaker attraction forces that are utilized to define physical characteristics of molecules such as:

  • boiling point
  • temperature
  • density
  • melting points

Hydrogen bonding is an type of intermolecular forces.

It is a type of dipole-dipole interaction that only happens when a hydrogen atom is connected to the atomic element of oxygen, nitrogen, or fluorine.

From the question given, in the propanol (CH3CH2CH2OH) molecule, the hydrogen usually has a partially positive charge which attracts the partially negative charge of the oxygen.

Therefore, we can conclude that the claim is True.
