What is nuclear fusion what role does it play in the sun
GalinKa [24]

Answer:

Nuclear fusion is when two atomic nuclei combine and form one nucleus. Nuclear fusion generates all of the Sun's energy. Inward pulling by the Sun's gravity is counteracted by outward pushing by the Sun's nuclear fusion; this balance keeps the sun from collapsing or exploding.

What leads to the formation of an ionic bond with Hg2+?
statuscvo [17]

The attraction of an SO_4^{2-} ion leads to the formation of an ionic bond with Hg^{2+}

<h3>What is an ionic bond?</h3>

Ionic bond, also called an electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

Since the question asking among all these options:

(a) The attraction of a noble gas

(b) The attraction of a NH^{4+} ion

(c) The attraction of a group 1 element

(d) The attraction of a SO_4^{2-} ion

An ionic bond can be formed after two or more atoms lose or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons.

Hence, option D is correct.

A gas system has volume, moles and temperature of 9040 mL, 0.447 moles and -35.50 oC, respectively. What is the pressure in atm?
babymother [125]

Answer : The pressure of the gas is, 0.964 atm

Solution : Given,

Volume of gas = 9040 ml = 9.040 L        (1 L = 1000 ml)

Moles of gas = 0.447 moles

Temperature of gas = -35.50^oC=237.5K       (0^oC=273K)

Using ideal gas equation,

PV=nRT

where,

P = pressure of the gas

V = volume of the gas

T = temperature of the gas

n = number of moles of gas

R = gas constant = 0.0821Latm/moleK

Now put all the given values in this formula, we get the pressure of the gas.

P(9.040L)=(0.447moles)\times (0.0821Latm/moleK)\times (237.5K)

By rearranging the terms, we get

P=0.964atm

Therefore, the pressure of the gas is, 0.964 atm
