Explanation: The awnser would be The effects of warmed water on aquatic life
Answer:
At about 51 °C
Explanation:
Hello there!
In this case, according to the attached solubility chart of potassium nitrate, our first step for this problem is to calculate the grams of this solute in 100 g given that 23 g are soluble in 25 g of water:
Thus, such solubility of 92 g in 100 g of water is exhibited at about 51 °C.
Regards!
Answer:
I think it is aluminombecause it just makes sense
Answer:
(A) II only
Explanation:
<em>If a compound has a number of individual dipoles, then:
</em>
<em>
(I) It is polar overall.</em> FALSE. If the individual dipoles cancel each other (as it happens in a symmetrical molecule), the net dipole moment is zero.
<em>(II) There is an electronegativity difference between the bonded atoms.
</em> TRUE. If the difference in electronegativity between the elements is higher than zero and lower than 1.7, the bond is polar covalent.
<em>(III) it is ionic.</em> FALSE. If there is a number of individual dipoles, the bonds are most likely to be covalent.
<em>(IV) It doesn't have resonance.</em> FALSE. There is no relation between the resonance and the polarity of the bonds.
