Which of the following elements will NOT reach an octet when in a bond?

Answer:

Within each element square, information on the element's symbol, atomic number, atomic mass, electronegativity, electron configuration, and valence numbers can be found. At the bottom of the periodic table is a two row block of elements that contain the lanthanoids and actinides.

Explanation:

Answer:

One week.

Explanation:

I would think one month because on weather websites you can see a month of weather. But the closer the day your looking at the prediction will be more accurate.

The most accurate range of data for weather forecasting is: A. one week.

Weather can be defined as the average atmospheric conditions of a particular area (region) over a short period of time.

Some examples of the elements of weather include the following:

In meteorology, the most common forecasted element of weather is temperature (degree of hotness or coldness) and it usually done a weekly basis such as one week.

The mass of lithium metal that is used in lithium batteries is 6.17 grams,  this can be calculated by using number of moles formula.

It is defined as the ratio between mass and molar mass.

It is given by:

Number of moles = mass / Molar mass

What information do we have?

Number of moles= 0.89 moles

Molar mass of Lithium metal= 6.941 g/mol

To find:

Mass of Lithium metal=?

On substituting the values

n= m/M

0.89 = m/ 6.941

m= 0.89*6.941

m= 6.177 grams

Thus, the mass of lithium metal is 6.177 grams.

Answer:

options B,C and E are correct conditions for forming hydrogen bonds.

Explanation:

In order for particles to stick together or shows certain characteristics, there must be a bond of attractions that is making them to be able to stay together. Some of these attractions are strong while some are weak. The kind of attraction that is being considered in this question  is the hydrogen  bonding which is considered as part of the weak forces of attractions.

In order for hydrogen bonds to occur, there must be hydrogen atoms [option B is correct] and a much more electronegative elements such as oxygen, Fluorine and Nitrogen. Hence, option C is correct.

Since the Fluorine or oxygen or nitrogen have much more electronegative properties than hydrogen, it causes a partial negative charge on  Fluorine or oxygen or nitrogen and a partial positive charge on the Hydrogen. Thus, option E is correct.

Answer:

0.57 moles (NH4)3PO4 (2 sig. figs.)

Explanation:

To quote, J.R.

"Note:  liquid ammonia (NH3) is actually aqueous ammonium hydroxide (NH4OH) because NH3 + H2O -> NH4OH.

H3PO4(aq) + 3NH4OH(aq) ==> (NH4)3PO4 + 3H2O  

Assuming that H3PO4 is not limiting, i.e. it is present in excess

1.7 mol NH4OH x 1 mole (NH4)3PO4/3 moles NH4OH = 0.567 moles = 0.57 moles (NH4)3PO4 (2 sig. figs.)"

Answer:

B. It becomes plutonium-239.

Explanation:

When uranium  - 238 absorbs a neutron, it creates and becomes plutonium - 239 atom.

 This is a nuclear fission process in which a radioactive nucleus is bombarded with a neutron:

  ²³⁸₉₂U    +     ¹₀n   →      ²³⁹₉₂Pu

The plutonium produced is not stable and it immediately disintegrates further.

Answer:

B.) It becomes plutonium-239

Answer:

9717.246 J

Explanation:

From the question given above, the following data were obtained:

Mass (m) of water = 40.5 g

Initial temperature (T₁) = 15.6 °C

Final temperature (T₂) = 73 °C

Specific heat capacity (C) of water = 4.18 J/gºC

Heat (Q) =.?

Next, we shall determine the change in the temperature of water. This can be obtained as follow:

Initial temperature (T₁) = 15.6 °C

Final temperature (T₂) = 73 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 73 – 15.6

ΔT = 57.4 °C

Finally, we shall determine the heat energy required. This can be obtained as follow:

Mass (m) of water = 40.5 g

Specific heat capacity (C) of water = 4.18 J/gºC

Change in temperature (ΔT) = 57.4 °C

Heat (Q) =.?

Q = MCΔT

Q = 40.5 × 4.18 × 57.4

Q = 9717.246 J

Thus, the heat energy required is 9717.246 J

Answer:

3 mol

Explanation:

Given data:

Volume of ethane = 15.0 L

Temperature = 30°C

Pressure = 5.0 atm

Number of moles of ethane = ?

Solution:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

30+273 = 303 K

5.0 atm × 15.0 L = n×0.0821 atm.L/ mol.K   × 303 K

75 atm.L =  n× 24.87 atm.L/ mol

n = 75 atm.L / 24.87 atm.L/ mol

n = 3 mol
