When two carbon atoms are covalently bonded together, they try to achieve an octet structure so their electrons are 4 in number while each of them donates their remaining 2 so they end up sharing 4.
Answer:
P= 0.87g/mL or 0.87g/cm^3
Explanation:
P=m/v
P=density
P=17.4g/20mL
P= 0.87g/mL
1mL=1cm^3
Answer:
<h3>THE CORRECT ANSWER IS</h3><h3>THE CIRCULATORY SYSTEM IS THE TRANSPORT SYSTEM FOR THE RESPIRATORY SYSTEM.</h3>
Below are the choices:
A The mercury will change temperature at a much faster rate under the same heating conditions.
<span>B The two metal samples will change temperature at about the same rate. </span>
<span>C The gold would float if placed in the mercury. </span>
<span>D The gold would sink to the bottom if placed in the mercury.
</span>
<span>a = false, it will take 0.031 cal to raise 1g Au 1degree while it will take 0.033 cal to raise 1g Hg 1 degree so, although Au will heat up faster, it will not be discernably faster so...
b = true
c = false, Au density > Hg
d = true</span>
Answer:
9L
Explanation:
Given parameters:
Initial volume V₁ = 3.6L
Initial pressure P₁ = 2.5atm
Final pressure P₂ = 1atm
Unknown:
Final volume V₂ = ?
Condition: constant temperature = 25°C
Solution:
This problem compares the volume and pressure of a gas at constant temperature.
This is highly synonymous to the postulate of Boyle's law. It states that "the volume of a fixed mass of gas is inversely proportional to the pressure provided that temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
where P and V are pressure and volume
1 and 2 are initial and final states
Input the parameters and solve for V₂;
2.5 x 3.6 = 1 x V₂
V₂ = 9L
