Answer:
82.97 K
Explanation:
Applying,
PV/T = P'V'/T'................ Equation 1
Where P = initial pressure, T = Initial temperature, V = Initial Volume, P' = Final pressure, V' = Final Volume, T' = Final Temperature.
Make T' the subject of formula in equation 1
T' = P'V'T/PV................ Equation 2
From the question,
Given: P = 877 mmHg = (877×0.001316) atm = 1.154 atm, T = 222.2 K, V = 7.9 L, P' = 0.327 atm, V' = 10.41 L
Substitute these values into equation 2
T' = (0.327×10.41×222.2)/(1.154×7.9)
T' = 82.97 K
Hence the new temperature is 82.97 K
B. The nucleus of an atom contains protons and neutrons.
The attraction between tow oppositely charged atoms or groups of atoms are an ionic bond
ANSWER______Ionic
Do you have more information than this
Is it a story?
1.Magnesium (Mg) has two electrons in its outer shell. Mg will <span>try to give two electrons to another atom (because the Mg is metal).
</span>2. When an atom loses electrons, it becomes <span>positively charged because its protons outnumber its electrons. ( In an atom, number of protons = number of electrons, when electrons are lost, the number of protons >the number of electrons.)</span>
