I really don't know what the answer is
Answer:
B. They can for covalent bonds with other atoms.
Explanation:
Carbon = King of the elements on the periodic table
For its proclivity to form stable covalent bonds with multivalent atoms.
0.781 moles
Explanation:
We begin by balancing the chemical equation;
O₂ (g) + 2H₂ (g) → 2H₂O (g)
21.8 Liters = 21.8 Kgs
To find how many moles are in 28.1 Kg H₂O;
Molar mass of H₂O = 18 g/mol
28.1/18
= 1.56 moles
The mole ratio between water vapor and oxygen is;
1 : 2
x : 1.56
2x = 1.56
x = 1.56 / 2
x = 0.781
0.781 moles
The hypothesis should be; "Increasing the amount of ice increases the rate at which the ice will melt"
<h3>What is a hypothesis?</h3>
The term hypothesis refers to a tentative explanation that could be applied in order to explain an observation. When we give a hypothesis, it must be subjected to rigorous experimentation thus it can be confirmed or repelled by experiment.
Now, we can see that the question here is; "How does the amount of salt added to ice affect the rate at which the ice will melt?" This implies that the correct hypothesis here ought to have to do with the impact of the amount of ice in the affirmative.
Thus, the hypothesis should be; "Increasing the amount of ice increases the rate at which the ice will melt"
