how many electrons does hydrogen need in order to have a full shell of valence electrons?

Answers

Answer:

One

Explanation:

In a hydrogen atom, the first outer shell only consists of two valence electrons, because it would already have one, the atom only needs one more.

It requires two electrons to completely occupy its outer shell, it frequently forms a single covalent bond with another atom. Because of this configuration, hydrogen can gain access to two electrons and completely occupy its valence shell.

What is Hydrogen?Hydrogen adheres to the duet rule because it only requires two electrons to completely occupy its valence shell. It deviates from the octet rule. Hydrogen only needs to form one bond. Because of this, H is always a terminal atom and never a central atom. Hydrogen is a chemical element with the symbol H and the atomic number 1.Hydrogen is the lightest element. Under normal conditions, hydrogen is a gas of diatomic molecules with the formula H2. It is colorless, odourless, tasteless, non-toxic, and extremely flammable. Hydrogen is a more environmentally friendly alternative to methane, also known as natural gas. It is the most abundant chemical element, accounting for 75% of the universe's mass. Water, plants, animals, and, of course, humans contain massive amounts of hydrogen atoms.

Answers

Heat required is mcΔT=100×0.39×50=1950 J

Solve any question of Thermodynamics with:-

The specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.

Specific heat capacity of the substance

The specific heat capacity of the substance is calculated as follows;

Q = mcΔФ

where;

c is the specific heat capacity

c = Q/mΔФ

c = (270) / (4.2 x 25)

c = 2.57 J/g⁰C

Thus, the specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.

Explanation:

2AlCl3 --> 2Al + 3Al2 If you produce 15 moles of Al, how many grams of AlCl3 decomposed? ​

FIRST, you need to write down the the correct reaction.  Your equation makes no sense

here is the correct question

2AlCl3 --> 2Al + 3Cl2    If you produce 15 moles of Al, how many grams of AlCl3 decomposed?

for every mole of Al produced, we decomposed a mole of ​AlCl3

so we produced 15 moles of Al, so we decomposed 15 moles of AlCl3

15 moles are 15 X 106.5 = 1597,5 gm AlCl3 decomposed

1.0g of solid AgNO3. They were told to devise an experiment to identify which compound was which. A student did so by adding 50 mL of distilled water to each beaker. Describe the student's observations that allowed him to identify each compound.

Answers

When the student adds 50 mL of distilled water to each beaker, CaCO3 will not dissolve in water while AgNO3 will dissolve completely in water.

We have to recall that according to the solubility rules, the carbonates of group two elements are insoluble in water. The solubility rules offer a convenient way of predicting the solubility of a compound in water.

A student graphed the position of a cart during a 7-second time interval.
Which statement best describes the cart?

A.
The cart was stationary except for a short burst of acceleration of 0.5 m/s².

B.
The cart accelerated at a constant rate of approximately 0.8 m/s².

C.
The cart was stationary with a velocity of 0 m/s for the entire 7 seconds.

D.
The cart moved at a constant velocity of 0.5 m/s for the entire 7 seconds.

Answers

Hi!
Answer: D the cart moved at a constant velocity of 0.5m/s for the entire 7 seconds.

The cart accelerated at a constant rate of approximately 0.8 m/s². Option (B) is correct.

Option B is the best description based on the graphed position data during the 7-second time interval. The cart's acceleration can be determined by analyzing the shape of the position-time graph.

If the cart was stationary, the position-time graph would be a horizontal line (option C). If the cart moved at a constant velocity, the graph would be a straight line inclined at a constant angle (option D).

However, the graph likely shows a curved line, indicating changing position over time. This suggests that the cart experienced acceleration. To further confirm, calculate the acceleration:

Acceleration (a) = Δv / Δt,

where Δv is the change in velocity and Δt is the change in time.

Given the time interval is 7 seconds, and the initial and final velocities are likely different, you can calculate the average acceleration. If the average acceleration is approximately 0.8 m/s², then option B is correct.

The graphed data aligns with the scenario of constant acceleration, supporting option B.

The Russian physicist Leon Theremin invented this instrument in 1920, and he exhibited his innovation all over the world. The instrument has an unusual appearance and consists of two metal antennas. The upright antenna controls the pitch, and the loop antenna controls the volume. The musician moves his hands over the antennas to create electrical signals,, which are magnified through the instrument and relayed to the loudspeaker. The theremin sounds ethereal and transports the listener to another world.The instrument became very popular in the 1930s, but it soon faded into obscurity due to a lack of interest. However, it was revived in the 1990s, and since then, it has been featured in the soundtracks of many movies. Many composers have created musical symphonies that showcase the unique notes of the theremin. It is one of the most difficult instruments to master because even a proficient player requires a lot of practice to control the intonation of the musical notes. Today, many enthusiasts also build theremins as a hobby using building kits available online.options:a.
