Yes, it is very likely that non metals will form an ionic bond with other non metals. This occurs through chemical bonds that are created by electrostatic attraction.

What is the difference between the grassland and savanna biomes?

goblinko [34]

Answer:

C)Grassland biomes contain mostly grasses.

Explanation:

The main differences between a savanna biome and a grassland is that grasslands biomes contain mostly grasses.

Savanna are made up of both grasses and shrubs.

Savanna are a mix of grasslands with some scattered trees in the area.
Grasslands are open grass fields.
They do not contain much trees as such.
The savanna and grasslands are renowned for their fauna diversity of beasts.

A reaction between liquid reactants takes place at in a sealed, evacuated vessel with a measured volume of . Measurements show t

Semmy [17]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The pressure is $P = 0.76 \ atm$

Explanation:

From the question we are told that

The mass of the carbon monoxide is $m_c = 17 \ g$

The temperature at which takes place $T = 30 .0^oC = 30 + 273 = 303 K$

The volume of the sealed vessel is $V = 20 .0L$

Generally the ideal gas law is mathematically represented as

$PV = nRT$

Where R is the gas constant with value $R = 0.0821 \ L \ atm \ mol^{-1} K^{-1}$

n is the number of moles of carbon monoxide which is mathematically evaluated as

$n = \frac{m_c}{M_c}$

where $M_c$ is the molar mass of carbon monoxide which is a constant with value

$M_c = 28 \ g/mol$

So $n = \frac{17}{28}$

$n =0.6071$

Now Making P the subject we have

$P =\frac{ 0.6071 * 0.0821 * 303}{20}$

$P = 0.76 \ atm$

g Tibet (altitude above sea level is 29,028 ft) has an atmospheric pressure of 240. mm Hg. Calculate the boiling point of water

Marina CMI [18]

<u>Answer:</u> The boiling point of water in Tibet is 69.9°C

<u>Explanation:</u>

To calculate the boiling point of water in Tibet, we use the Clausius-Clayperon equation, which is:

$\ln(\frac{P_2}{P_1})=\frac{\Delta H}{R}[\frac{1}{T_1}-\frac{1}{T_2}]$

where,

$P_1$ = initial pressure which is the pressure at normal boiling point = 1 atm = 760 mmHg (Conversion factor: 1 atm = 760 mmHg)

$P_2$ = final pressure = 240. mmHg

$\Delta H_{vap}$ = Heat of vaporization = 40.7 kJ/mol = 40700 J/mol (Conversion factor: 1 kJ = 1000 J)

R = Gas constant = 8.314 J/mol K

$T_1$ = initial temperature or normal boiling point of water = $100^oC=[100+273]K=373K$

$T_2$ = final temperature = ?

Putting values in above equation, we get:

$\ln(\frac{240}{760})=\frac{40700J/mol}{8.314J/mol.K}[\frac{1}{373}-\frac{1}{T_2}]\\\\-1.153=4895.36[\frac{T_2-373}{373T_2}]\\\\T_2=342.9K$

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

$T(K)=T(^oC)+273$

$342.9=T(^oC)+273\\T(^oC)=(342.9-273)=69.9^oC$

Hence, the boiling point of water in Tibet is 69.9°C
