The given 2 triangles are similar

Explanation:

Step 1 :

Given,

ABC is a triangle

N is the point on AB so that ∠ABC = ∠ ACN

We need to show that the triangles ABC and ACN are similar

Step 2 :

Two triangles are said to be similar if the corresponding angles are equal.

In the given triangles we have

∠A as the common angle

∠ABC = ∠ ACN

Since 2 angles of both the triangles are same, the third angle is also same, because the sum of the measures of all angles is 180 degrees

Hence the given 2 triangles are similar

Fill in the coefficients that will balance the following reaction:

dalvyx [7]

Answer:

C₃H₈₍g₎ + 5O₂₍g₎→ 3CO₂₍g₎ + 4H₂O₍l₎

Explanation:

Propane is an alkane that burns in enough oxygen to produce carbon (iv) Oxide and heat as the only by products. Balancing the equation: The number of atoms of each kind on either side should be equal. Hydrogen on the left has eight atoms same as the right side after balancing, oxygen has 10 while carbon has 3 on each side.

A mixture of methane and krypton gases is maintained in a 8.99 L flask at a pressure of 1.68 atm and a temperature of 46 °C. If

sweet-ann [11.9K]

Answer:

22.81 g

Explanation:

Given that:

Pressure = 1.68 atm

Temperature = 46 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T = (46 + 273.15) K = 319.15 K

Volume = 8.99 L

Using ideal gas equation as:

PV=nRT

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = 0.0821 L.atm/K.mol

Applying the equation as:

1.68 atm × 8.99 L = n × 0.0821 L.atm/K.mol × 319.15 K

⇒n = 0.5764 moles

Given that :

Amount of methane = 4.88 g

Molar mass = 16.04 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{4.88\ g}{16.04\ g/mol}$

$Moles= 0.3042\ mol$

Moles of Krypton = Total moles - Moles of methane = 0.5764 - 0.3042 moles = 0.2722 moles

Also, Molar mass of krypton = 83.798 g/mol

So,

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$0.2722\ moles=\frac{Mass}{83.798\ g/mol}$

Mass of krypton = 22.81 g
