Lets get this straight:-
Protons → Positive charge, found in nucleus, heavy
Now, the only one we see that seems to be correct is A) positive charge, heavy, found in the nucleus of an atom
Answer:
345.44 g or 0.34544 kg
Explanation:
Applying
D = m/V...................... Equation 1
Where D = Density of mercury, m = mass of mercury, V = Volume of mercury.
make m the subject of the equation
m = D×V................. Equation 2
From the question,
Given: D = 13.6 g/mL = 13.6 g/cm³, V = 25.4 cm³
Substitute these values into equation 2
m = 13.6×25.4
m = 345.44 g
m = 0.34544 kg
Hence the mass of mercury is 345.44 g or 0.34544 kg
Answer: Cesium chloride dissolves in pure water has 
> 0.
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
is positive when randomness increases and is negative when randomness decreases.
a) 
As 2 moles of gas are converting to 1 mole of gas and 1 mole of liquid, the randomness decreases and hence is negative.
b) 
As gas molecules are converting into aqueous and liquid form, the randomness decreases and hence is negative.
c) lithium fluoride forms from its elements: 
As elements are combining to form a compound, the randomness decreases and hence is negative.
d) Cesium chloride dissolves in pure water : 
As compound is dissociating into ions, the randomness increases and hence is positive.
Answer
Used up faster than they are able to be replaced
Explanation:
The word renewable itself mean non-depletable or naturally replenish able. They cause little to no environmental impact that it can be used for long term. They are available in plenty and cannot be used up in quick time. Hence option a is correct. Rest all are correct about characteristic of a renewable resource
