Answer:
374°F
463.15K
Explanation:
This particular Question wants to test knowledge on the conversion of the units of temperature from celsius degree to degree Fahrenheit. Also, the conversion of degree celsius to kelvin.
The value given which is 190 degree celsius can be converted into degree Fahrenheit using the formula below;
(x°C × 9/5 ) + 32.
Therefore, x = 190°C =( 190°°C × 9/5) + 32 = 374°F.
The conversion of degree celsius to kelvin is given below as;
x°C + 273.15 .
Therefore, x = 190°C = 190°C + 273.15 = 463.15K.
Therefore, the temperature needed to bake at Fahrenheit and kelvin are 374°F and 463.15K respectively.

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.
Gases in which the molecules that make it up naturally consist of two atoms of the same type.
