H and Br are both non-metals which means the bond that comes in between them is covalent. If the composing elements are non-metal and metal, then the bond should be ionic. In this case, HBR is considered polar because the Br atom pulls on the electron much harder than the H atom. Answer is C.
Answer:
Being a weak acid and a strong base, where it is diluted in a neutral medium such as water, the basic medium predominates, almost alkaline pH.
Explanation:
The acidity of the solution, being weak, means that its pH is not so low, therefore it will be easier to reach the values of 7 or 7 where alkalinity or basity is indicated.
Answer:
200 °C
Explanation:
Let’s convert all the temperatures to the same scale, say, Celsius.
<em>Celsius</em>
Water boils at 100 °C, so 200 °C is the temperature of <em>superheated steam</em>.
<em>Fahrenheit
</em>
Water boils at 212 °F, so 200 °F is <em>just below the boiling point of water</em>.
<em>Kelvin
</em>
Standard temperature is 0 °C = 273.15 K. Ice melts at 273.15 K (0 °C), so
200 K is <em>well below the melting point of ice</em>.
C = K – 273.15
C = 200 -273.15 = -73 °C
Thus, 200 °C is the hottest temperature.
The symbol for copper is CU, which means copper cuprum, the Latin word for copper.
