Natural gas is comprised of methane with small amounts of ethane,propane,butane and pentane.

The simpler molecular structure of natural gas enables a clean burn, so it's combustion does not produce solid particles or sulpher. It is used for heating,cooking,electricity generation and fuel for some cars.

Where are Metals and nonmetals found on the periodic table

vovangra [49]

Metals are found in group 1, 2, and abit of 3.
Non-metals are found in group 0/8, abit in 4, 5, 6 and 7 too. Here is a picture. Most of the periodic table are metals.

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's asserti

nadya68 [22]

No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect

<h3>Perpendicular lines</h3>

In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

$m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1$

For the slope of ln:

$m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\$

For the slope of mn:

$m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\$

If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

$m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2$

Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect

The area between z= -2.31 and z= 0.47

siniylev [52]

Answer:

0.67038

Explanation:

One z-value is negative and the other is positive.

This means we are looking for area between the two given z-values on opposite sides of the mean.

From z-table attached, the area at z = -2.31 is 0.98956

Also, from the second z-table attached, the area at z = 0.47 is 0.68082

But since we are looking for the area between both z-scores, we will now have;

P(-2.31 < x < 0.47) = (0.98956 + 0.68082) - 1

P(-2.31 < x < 0.47) = 0.67038

Determine the formula weight of ca(no₃)₂. provide an answer to two decimal places.

Ronch [10]

The formula weight of $Ca(NO_3)_2$ is equal to 136.02 g/mol.

The formula weight of a chemical compound is calculated by adding the atomic masses of each chemical element contained in the compound, while multiplying them by the number of atoms respectively.

From the periodic table, the atomic mass of each chemical element is:

Carbon = 12.0107 u

Nitrogen = 14.0067 u

Oxygen = 15.999 u

Formula weight of $Ca(NO_3)_2$ = $12.0107 + [14.0067+ (15.999 \times3)]\times 2$

$F = 12.0107 + [14.0067+ 47.997] \times 2\\\\F = 12.0107 + 124.0074$

F = 136.02 g/mol.
